Re: 1991 ST 1100 overheats when Im not going 45-55 mph. Water pump? Thermo switc
It will run out of coolant and overheat again. At that age the hoses and elbows and all gaskets should be replaced. My 97 thermostat came out in pieces as they have been known to failure and mine had. Overflow tube, hoses, thermostat, elbows, elbow gaskets, thermostat gasket, and go ahead and replace your hose clamps while your in there too. I had a few bad ones. The parts arent that expensive, but it ate up a whole weekend for me doing it. Go ahead and clean the carbs too. I thought my bike was running fine but when I opened the carbs all 4 pilot jets and emulsion tubes had blockages. Almost feels like it could wheelie now in comparison to how it was before
