Put red ST1300 for sale last week. Bought a newer blue one. Took red for ride yesterday. Of course it developed a problem.... Pissed at me for putting for sale sign on her!!
over heating. Fans both working. Spitting coolant. Gauge went to 5 bars many times. It has never gone past three bars before. Limped it home after many stops to let it cool. Tore it apart today. Rad full. I assume thermostat. Just removed thermostat. How do I know if if it is stuck closed. 1000,000 kms, never replaced thermostat before.
Is this stuck closed? Are there measurements for open and closed?
Closed is closed. Boil water, put in a mixing bowl and dump the t-stat in. If it doesnt open right away it is toast as long as the water is above 180F. Cant see from the photos but is the brass etched on the inner sleeve? Green corrosion there as well?
