Coolant Leaks

[hippo888]

Terry on the MSN board asked this first: Is there an endemic problem with coolant leaks on the ST1300? It seems like too many people are reporting problem(s) for it to be an isolated issue. If possible, could you please post your mileage (and leak status) too? I'd like to see if the problem is isolated to higher mileage bikes or applies across the ST1300 population.

[hippo888]

Water tight at ~5,000 miles.

[dond]

That's 100% so far 8)

62,500 miles

fingers crossed

[Mellow]

I'm assuming I have two leaks, one at the thermostat area and a gasket/housing leak at the water pump.

Once I find out more, I'll update w/comments.

[clmixon]

04 non ABS No leaks @ 6800 miles. Had all the plastic off last week so I looked around pretty good.

[Daryl]

"SEEP" 1300 might be a better name for mine!

During the cylinder valley plug oil leak @ 600 miless the waterpump seal was replaced, then a new waterpump 2 weeks later, still seeps to this day @ 8,000 miles. Smell it on occasion. Have lines of dried antifreeze running down the right of the engine case always. Not much but............should be none.

Read one post somewhere about the front case not being square / level??

[dond]

Uh-oh, we're now at 30% leakers :(

Maybe we should go by leaks per 1000 miles? 8)

Make sure we all take the bikes in for this..Mama does track the repairs and I know she races ahead at glacial speed but they will be addressed. It took 1 year to get a response from Mama regarding my wire rub/short.

One problem the FJR owners are having is not all owners are reporting problems to Yam and Yam is NOT going to respond to nothing!

My situation. Second day I had the bike I rode up to Morrow Mountain in 90 deg heat, about 60 miles. Stopped and parked and two minutes later saw a larrge puddle of antifreeze under the bike. Rode home , parked no more leak. Two weeks later after a ride in hot weather another puddle under the bike. Since then in five months, not a drop. One thing. the dealer had WAY overfilled the coolant overflow tank so my best guess is it was burping a bit out the overflow tube. I took some coolant out and no more problems.

[dannyk]

Posed this same question on another site, I don't speak, write or read German, french, Italian etc. but anyone that does are the Pan europing bikes having the same problem? Being that there are more sold in Europe etc. it should be more prevelent there, and will most likely get the fix there first if H owns up to it. I remember the stator failures on the 1200 wings that never had a problem but I replaced 2 of them in 70 thousand miles, and just about everybody that I talked to that had a early 1200 did the same.

[Lola]

Today I took mine to the shop for the recall and another leak (3 seperate trips to the dealer for leaks). I'm tring a differant Honda dealer this time.
Took to dealer first time for leak at 18557 miles, second time 18850 miles and now the third time at 20268 miles.

Wow, you have dealers there that are open on Mondays?
All of them here are closed on Mondays.

[BentAero]

I swear you guys put a hex on my bike. I hadn't paid any attention to the 'coolant leaks' threads at all until last week, when I finally read them. No sooner than I had done so, the very next time I started my bike... drip, drip, drip.

'04, 10,500 miles. Never a problem until just after the bike sat (covered) outside for a couple days in temps that got down to about 5º f. I started it up to move it, and after shutting it off, the drip appeared right away. I tore the bodywork off, and sure enough, leaking from the water pump cover. Dealer closed up for Christmas/NewYears so I can't even get it scheduled yet.

Could being exposed to the cold temps have anything to do with the leak starting?

I'm leaving the plastic off when I take it in. They can do the ground recall at the same time.

[dannyk]

Most definatly the cold weather will cause them to start to leak, my Wing never leaked until the weather got real cold, bike is stored in a seperate garage with heat and the other toys. Any way I didn't have the heat on yet and there was a small puddle under the bike, when the furnace was lit and it warmed up in the garage the leak quit, turns out it was only a hose clamp that needed to be tightened. Contraction of the metal parts when they get cold.

[dond]

Not uncommon for cold weather coolant leaks.



The dry guys are leading!!

GO DRY GO!!

[crazykz]

11,000 miles and I've had one leak but I'm almost positive it has been leaking since about 1000 miles.

04' ST1300A in Wisconsin.

Curt

[MikeP1300]

Yes, 4K miles, 2 visits. Hose clamp and currently in for water pump and front cover.

I guess that's 2 leaks.

[seiseman]

10K miles and dry. (As of three weesk ago.) Some of you are starting to make me nervous. :confused: I haven't been out to the bike in three weeks and I think I will go out to the shed to say hello tonight. :chatter:

What !!!!!! you don't make a nightly ritual of visiting your ST and dreaming of warmer days ??? What the heck kind of ST owner are you ????? :)

[ssls6]

I voted as "1" leak but it started leaking again. I just returned from a Big Bend, Hill Country romp and noticed the distinctive smell and dried glycol traces. My first leak was found at 3k miles. I noticed my latest leak at 7k miles. My current mileage is 8.2k.

[dond]

If mine STarts leaking I'm changing to Evans and riding :mcrider: on..and on..and on.

No pressure = No leaks!

[georgeorge]

hey don.....problem with that theory is that my bike has not been started for two weeks and there were no leaks until yesterday. So there was no pressure in the system when it leaked!

Brian

[eddiemack]

3000 miles on my 2004. I've riden extensively in the teens and twenties before putting it away for the winter. Although it dropped the oil level a bit the coolant never leaked. I'll have to pick up a roll of duct tape just in case....

[Purm1300]

Don,

I checked the site and Evans is a propylene glycol base.
Amsoil has a propylene glycol coolant that I have been using for years in my autos.
It was designed for use in aircraft engines and is most compatable with aluminium block engines.

Andy

[ST13-JHW]

I've had one leak on my 2003 ST1300A. The bike was parked in the unheated but attached garage for the winter (2003-2004 winter). A puddle about 3 inches or so in diameter. The outside temp was well below zero F. No more leaks since then. :confused:

[Dketchum]

I went to the Dealers today and talked to the Service manager, I told him about where the coolant was leaking and he said that I would be the Guinea pig for them on working on the ST1300 :eek: Also said he couldn't schedule me for the recall work cause I didn't buy bike there so parts were not allocated to him for my bike and that he can't order the parts yet because Mother Honda hasn't opened up for ordering yet.

I really think I may take care of this leak on my own. I can get the parts from Service Honda for about $35.00 and have read the service manual and have the tools to do the job.(not all the 'Special Honda Tools'), but I can make due. I really don't want to be the Guinea pig here. In any case, I am not going to take it in till they can address everything at one time..We are in prime riding season here in South Texas...It was 84 degrees today!!!!!

[Don Webster]

2003 No leaks so far 22000 miles. ;)


After writing this it will probley be leaking next time I look. :mad:

Don W.

[georgeorge]

My 2003 with just over 7000 leaked last week a wet spot in the garage about 3 inch in diameter. I started the bike up....let it warm to 3 bars....shut it off....cleaned up the coolant that had dripped.....burnt my knuckle on the exhaust header (^*%#@#&!!!)...and no more leak so far! I think the bike was just letting me know how it felt about sittin' there in the garage.....all alone.....and so once I burnt my knuckle if felt some crazy sort of revenge toward me had been taken care of. It just leaked to suck me into burnin' my knuckle!

Me and my bike are now at peace and just waiting for warm weather!

Brian

[sandman]

900 miles this morning and no leak so far.

Bike has only seen a temp spread from 40f to 75f so far.

I keep it stored in an unheated attached garage.

Gordon

[Dketchum]

No on doubling the gaskets, that would move the housing out and also change the amount of engagement of the water pump drive shaft.

The pn's I used are:
19217-MAL-300 mechanical seal
19226-MCS-000 Gasket
91201-148-003 Oil Seal.

Dave

[hippo888]

So far, I've got 18 people who gave me mileage figures (11 no-leakers and 8 leakers).

Since the sample size is so small, conclusions are pretty meaningless.

No Leaks: :D
Median mileage with no leaks: 5,000 miles.
Mean mileage with no leaks: 11,345 miles.
If you get rid of the outlying score of 62,500, you get a mean of 6,230 miles.

Leaks, using first occurence: :mad:
Median mileage with leaks: 7,000 miles.
Mean mileage with leaks: 6,380 miles.

Meaningless conclusions:
Looking at median mileage, there is a tendency for bikes to leak as they accumulate mileage. However, the mileage is pretty low, only 7,000 miles.

If you have a leak, 36% of one-leakers turn into multiple-leakers. Not good.

If more people could post their mileage and leak status, we can get more meaningful conclusions.

thanks!

[Dketchum]

I agree, I put 10K miles on it this summer in trips etc..then It didn't start to leak till the temps started to drop...from 100-105 in summer down to 35 at night here. Temps went back up here to 75-80 and now it won't leak! : :(

[georgeorge]

mine was a 3 inch diameter wet spot....not even a puddle. I had to get a paper towel and soak up a little to confirm it was green. But since I warmed up the bike and cleaned up the mess...no more leak.

Brian

[Mellow]

I didn't even know mine was leaking until I took the plastic off and saw the line of anti-freeze residue on the side of the engine case. Mine has been a very slow and very small leak, not sure how long it's been there so I don't know how many miles or when it started.

Boy, that ought to screw up your statistics a little... lol :D

[BentAero]

Just FYI: In addition to my 'only when cold' water pump leak, I had an even bigger leak coming from one of the hose clamps on the "T" shown in the photo. Nearly every hose clamp on the bike was mildly loose.

[dbst1300]

I've owned two 2003 ST1300ABS bikes.........13,500 miles on the first with no leaks and 14,000 miles on the second with no leaks.

[AZST]

1675 miles...not a drop.

[georgeorge]

I'm starting to agree that it's a temperature related issue, so I've commited myself to going into the garage and start the beaST for a couple minutes every couple days. I'm thinking that it has to do with the way aluminum and stainless steel contract and expand with changes in temp. When it gets cold, for some reason, the stainless bolts that hold the cover on don't expand/contract at the same rate as the aluminum block & pump housing causing a loose gasket and thus a drip.

I'm no engineer so I have no data to back this up......It's just a theory......but sounds good. Would explain the situation the way it DOES happen.

Brian

[tccox]

Day two of ownership of new ST, rode to Morrow Mountain on a 90 deg F day. Got to top , parked, and after about three minutes bike spit out about a 3-4" diameter circle of antifreeze.

2 weeks later, 60 mile ride on blistering hot day, got home parked, three minutes later same 3-4 diameter circle

Checked coolant overflow tank leve, noticed dealer had WAY overfilled tank, coolant was at very top of tank, I siphoned some out. No more leaks since July

[Kirby]

I'm at the first stage of having a leak.....I smell anti-freeze when I ride and stop. And I just had the tupperware off last week doing farkles!...Drat!

[Fireball18]

'03 nonABS, 15500 miles, very minor leak at around 15K. Dealer replaced water pump gasket seal. So far so good. Wife's '04 has 8500 miles and no leaks.

[The Highwayman]

My 2003 has about 15,000km (10,000miles) and I've never noticed a leak.

I've only owned it for about 4 months/3000miles and you guys are making me paranoid. :confused:

But it is too flipping cold in the garage to go check tonight... :mad:

[gunther1300]

05 abs no leak yet. Its not being delivered for 2 weeks yet though. HAHAHAHA

gunther1300

[AgSTreak]

Brian, you may have hit the nail on the head. I'm a material engineer with an aerospace company. Aluminum has a much higher coefficient of expansion than steel. For any given rise or drop in temperature aluminum will expand or contract more than the steel for a given length. Simply stated, when the temps drop a small gap may/will develop due to aluminum shrinking more than steel. On a positive note, running your engine raises the temperature of the associated parts and closes the gap. For example, the super fast SR-71 Blackbird leaked fuel like a sieve until heat from friction sealed the leaks in the titanium skin. The SR-71 was designed that way.
Quote- "At rest on the ground, fuel leaks out constantly, since the tanks in the fuselage and wings only seal at operating temperatures, the Blackbird stretches a few inches during flight.
There is little danger of fire since the JP-7 fuel is very stable with an extremely high flash point."

[gunther1300]

It being aluminum may be a contributing factor but its no excuse!!! Honda has billions of all aluminum engines in cars that don't leak coolant and some of them cost less to buy than the ST-ABS :mad:

Gunther..they are asking for you on the FJR ezboard..They wanna know how your new ride is doing.

And then probably rip your lungs out! :-) rough crowd sometimes.

[gunther1300]

They have to wait 2 weaks yet, I told them that in my last post. My dealers said it was not arriving until Feb 2nd. I know their waiting to try to kick my butt again. Bring it on. As I see it I am one of only a few that did something to show Yamaha how crappy they are treating their costomers regarding the ticking issue. (getting rid of that POS).

26k, '03, No Leaks. Cold weather once caused a re-occuring leak in my bathroom so I suppose it could happen on a bike too. Proper torquing was the solution. If I had a re-occuring leak on my bike, cold or no cold, I'd be watching for the lemon law to kick in. :(

[georgeorge]

Green fluid leaks are Limes, not Lemons. Lemons are yellow! :crackup

[dond]

Roll it into a walk-in freezer, wait a few hours....Torque everything to spec and ride baby :mcrider:

[Kennedy]

7000 KM and not a drop. And it better not start after I hit the submit button. Just had her out in -7 C weather with no problems and she is stored in an un heated shed.

[zed x]

3,600 miles, my 04 st leaks when cold but it stops when it warms up had the plastic off and started the bike when it was cold and it started to leak from around one of water pump cover bolts near the top water pump cover but as it warm up it stops.

[JOHNNYST4]

No leaks at all.

ST4Johnny :D

[mishkee]

warming it up at work gettin the gear on talking to a guy ... and he goes you have a coolant leak... ah nice new bike... bright green spewing... UGH

[steve18]

Today I notice a very slight amount of coolant on the right side at the bottom of the engine. When I looked in the right side of the engine, I saw 3 hoses connected to a T. There appeared to be a clump of dried coolant. I am attaching a picture.

Has anyone else had any leaks from this location?

Thanks,
Steve

[drhude]

I have a small leak occasionally coming down the right side of the engine block. Leaves a puddle about the size of a nickle. Had it to the dealer once they can't find anything. It doesn't leak all of the time. I have 4000 miles on my 04 and this problem has been present for the last 1500 miles.

[Carl_T]

nothing so far (fingers crossed).

[kingprawnokay]

No leaks after 11,000 miles. Could it be a dealer issue?

[Rider]

I haven't noticed any leaks yet.
But you know what's weird? After a ride on a hot day, when I pull the bike into the garage and put it up on the center stand, it will burp. I'm not kidding. I hear a * gurgle gurgle glug * sound. :confused: :nuts1: :-o

[kingprawnokay]

My Z1000 whistles like a tea kettle when I turn it off.

[ST1300CAZ]

Drhude:

I had the exact nickle size drip you have... but it only happened in the winter at temperatures below 45 degrees upon start up and warm up.... then it would stop. I agreed with others that it was hose clamps. So when I had my recalls done I had all the clamps tightened and have had no problem since.

I do routinely check my coolant and it seems I add some every year. Be careful not to overfill.

Hope this and the other posts help !

[tccox]

Been over a year now and no more leaks since the two incidents 1 day after I got the bike and then once more a week later. Only thing I could figure was coolant tank was overfilled. No more leaks since and each time I change oil I also remove the lower fairing to check for leaks.

[buckeyest1300]

04 with 3300 miles on it. No leaks so far.

[Mongo]

5500 miles on 04, leaks when engine is cold, stops when engine warms up. This is the only downside I have with this bike.

[jsl]

I have 26000 on the 03, I've topped off the coolant tank a few times, but no visible leaks so far

[wjbertrand]

'05 with no leaks, no funny smells at 10,500 miles. I did tighten every hose clamp I could see when I had the tupperware and air cleaner off. Some seemed pretty loose. Perhaps I pre-emted any leaks that way. My ST1100 experienced 2 leaks over it's 150K with me, both happened after I'd replaced all the cooling system hoses at about 88K. In both cases I found the clamps were too loose. I think the hose material "creeps" or takes a compression set initially. Once I followed up and tightened all the clamps there were no further issues.

[RON S]

No Leaks At This Time :)

[Drew]

'05 with 8500mi, no leaks (please Coolant Gods)

FWIW...why the hell does Honda have 871 hose clamps and coolant lines on the ST? It seems they could have intergrated some of these internaly to the engine.

Note To All St1300 Owners:
I Have Owned 2 St1300a's In 2 Weeks ( Hence The Tag, 02hst) Of Each Other.
After Taking Delivery Of The First Machine, Rode Home 27km, Machine Was Leakig Oil To The Dripping Off Sump Fins Stage, Coming From The Oil Gallery Plug Apparently. This Was Confirmed By Honda Australia Head Office, Only After It Was Stripped And Checked,the Second Time At Head Office Service Centre.the Dealer Rightly Refused To Tackle The Job, After I Insisted That I Want A New Replacement Machine, Honda Australia Came To The Party And Supplied A New Machine 2 Weeks Later. Alas ,the Second Machine Leaked Coolant, Is Now On It's Second Water Pump And Cover. WITH ONLY 6,700 KMS AS OF 19/4/06 BIKE IS NOW 3 MONTHS OLD
I Have Little Faith That This Will Fix The Problem Permanently.
Having Been A Honda Motorcycle Mechanic For 15 Years In My Younger Days,don't Hold Your Breath For A Remedy To This World Wide Problem.

[eddiemack]

Leaked at 2000 miles in cold weather only. Dealer couldn't find a problem. Leak became more non weather related so I fixed it. Clamps loose at thermostat housing. Took the opportunity to flush cooling system. Leaks appear to be a thing of the past.

[PanAmerican]

'05 ST1300A
8800 miles
no leaks to date

[billxp]

No leaks here yet.
:biker: 14K miles took delivery in Sept of 2005.

[ccryder]

Hmmm, seems like Indigo has done pretty good, 47,000 miles in 2 years. Just Monday I noticed a telltale smell when changing my oil. Viewing through the opening in the mid-cowl I could see the signs of a weep from the "weep" hole. No puddles on the floor or lower cowl.

Time for a water pump seal, bearing, oil seal, and cover o-ring. My Dealer is ordering the parts. I had all the tupperware off in January and did a T-stat R&R. At that time the weep hole was not weeping.

Neil S.

[805gregg]

'04 12,000 miles, in the shop yesterday for drip out of weep hole on water pump, not a bad leak, sometimes a little leak, sometimes no leak,if it wasn't under warrantee I would have ignored it.

[ccryder]

That is about what mine is like. If I had been riding in the rain or given her a good washing then the evidense would be gone. From my background and experience and from reading the SM, even a small weep is reason to change the seal(s) and bearing.

Neil S.

[RideCoach]

15,649 miles in Sunny Florida no leaks

[Slider13]

My '04 is leaking again. Not alot, but the same small puddle coming from the thermostat housing. I had it fixed last summer for the same problem at the same location. They replaced the 5 different seals as I was told. It took them 2 weeks to get all the seals, some were on back order.

Slider13 :04biker:

[IndyST]

My 03 (26K) would only leak in the winter durring temperature swings. First of March had the thermostat & o-ring relaced under waranty. Fine now.

Mike

[DocNeal]

2004 non-ABS, one leak at 3200 milage. Leak was from a hose connected to the thermostat. Search "coolant leaks" on this site and see my photos. My leak also occured when I first started her up after sitting in the garage through the cold winter. Temp was 40F when I first started up.

[maxedout]

20,000 plus miles on 05 and no leaks.
If the water pump housing is leaking has anyone checked the torque?
I had slight oil weeping on the bottom front off the engine and found two bolts barely hand tight. Torqing them stopped the weep. I wonder if undertightening some bolts at assembly may be the problem?

[SupraSabre]

Since my trip up to Sacramento last month, I've been smelling coolant. I took off the tupperware and opened up under the aircleaner to look for a leak. So far no dice. I'll need to remove the radiator next to look. :(

And BTW, I have 32K now.

[Gem STate ST]

06ABS 8,000 miles no leaks but it hasn't gone thru a winter yet as it was at the dealer until 6-19-07.

[Mike]

Mine still leaks. Three times in the shop at two different dealers. Last one replaced the waterpump though I told them that there was NO coolant from the weep hole, It leaked from the weep hole within 10 miles after the replacement.

Sure I can do the job right myself but I have a warranty....next shop visit I am going to invite the regional rep to have a look in to the leaks issue....Four times in the shop for the same issue is three times to many.

[S2000-Dave]

My 05 hasn't leaked a bit,,,oh wait,,its a Road Star air cooled,,oooppppssss. My 04 ST leaked once,,in the dead of winter when I started it up, it was -10 degrees out! Only time! Started it to keep the parts lubed

[04ST1300TX]

Smell it on occasion. Have lines of dried antifreeze running down the right of the engine case always. Not much but............should be none.


+1 !

I bought my 04 ST 1300 used with 4200 on the clock 18 months ago. The dealer replaced the water pump and seals before I bought it. I now have 21860 and smell coolant any time I come to a stop. I plan to take the plastics off next month find and fix the problem.

[John-DownUnder]

By deduction, my first coolant leak at 56,000 miles (90,000 km)! No sign of coolant from the outside or on the floor. No obvious odour from evaporating coolant (note: no antifreeze in use in Australia - only anti-rust).

At the recent 90,000 km major service, the workshop guys reported a very low radiator reserve tank and no obvious signs of leakage. A week or so later, the reserve tank was almost dry again!

I have searched this Forum (open threads) and the My-MC forum for details from others on coolant leak fixes, however the only major threads I found pertain to ST1100s. My next steps will be to ascertain more accurately the rate of loss of fluid, to inspect the bike more closely after a ride, and to remove the fairings and tank etc to look at all the possibilities.

Can anyone point me to threads here on specific (common?) ST1300 coolant leakage problems with fixes.
Cheers

CheersInteresting. Your avatar shows you standing in a snow drift, yet you use no antifreeze? Antifreeze is more than just antifreeze. 50/50 antifreeze/water mix adds cooling capacity and raises the boiling point of your coolant system all while protecting from corrosion.

Perhaps your radiator was also low and the coolant added to the reservoir is now in the radiator. I would check the coolant level in the radiator, top off the reservoir and see what happens. Also take a good look at your radiator cap.

[John-DownUnder]

Interesting. Your avatar shows you standing in a snow drift, yet you use no antifreeze?

Perhaps your radiator was also low and the coolant added to the reservoir is now in the radiator. Thanks for the advice, hawkeye. Will check those.

The photo was take on our trip through Europe (May to September 07). It only got down to 3 degrees C through one of the Swiss passes. As these low temperatures were only brief on a couple of occassions, I simply ran the entire trip on my standard fluids from Australia.
Cheers

For the poll to be accurate my vote counts twice. Damn, I should have been a Democr...... Nope can't even say it!

[Mike]

Three times in the shop for antifreeze leaks. I wrote Honda of Torrance inquiring what it's gonna take to get this fixed..no reply x 2 letters. My ST is still marking it's territory with green puddles....

[acedantinne]

PULL THE PLASTIC AND TIGHTEN THOSE HOSE CLAMPS. THERE IS A COUPLE UNDER THE THROTTLE BODY HARD TO GET AT.
THAT WILL TAKE CARE OF YOUR PROBLEMS.

[johnephlin]

At 60K while checking my valve clearances I noticed a slight leak at the water punp mechanical seal, I called my dealer and was informed that it was to be taken care of under warranty, what a bike. 05-the fast color.:biker: :biker: :bow1:

[GitGoFast]

I voted Yes – Single but I don’t think I have a leak per say. Story; There is a small amount of coolant on the driveway during warm up. I checked the reservoir and found it rather difficult to read the level, the casing is too opaque. After getting in closer the level looks way too high. I think (speculation, I never asked) the dealer checked it but not very carefully, he couldn’t see through the case and thought it was empty. He then “topped” it off as a courtesy. Ooops. Will there be a problem (other than the mess) if I just leave it as is or should I somehow adjust the coolant level?

As of today, no leaks at 22706 miles and just had plastics off last week.

There is a small amount of coolant on the driveway during warm up.

Congratulations, you have a leak! :radleak: I should qualify that: if it's at the front of the bike, you have a leak. If it's in the middle, it's normal (see below).

The system will eventually purge itself to the right level. As the system heats up, the coolant will expand out of the radiator into the recovery tank and will be sucked back in as it cools (and contracts). If the tank is too full, the excess will run out through the hose at the filler neck and get dumped onto the ground.

I get a smell in the colder weather but never a puddle. Are the people with leaks losing fluid and getting a puddle or just a smell from time to time?

The smell is the beginning of a bigger leak.
