I've taken the coolant thermostat out to test it - it opens at around 90deg, and will close in cool/warm water, so I'm sure it's working....
Starting from cold, the 'water temp' needle will climb to 90-95, then obviously the therm opens and it seems to plummet the temp to 80 (or below - that's as low as it goes). Then it never heats up again?
I've previously replaced the therm as it was stuck open, but that's not the case now (as it does heat up?)
It seems it doesn't close when it should??
Maybe it's fubar'd and it's only closing when properly cold - does that happen??
DrP
