i fannied around a bit when engine was totally cold. unplugged the stat sensor, sprayed it. plugged it back on. checked all fluid levels and started it up with expansion tank cap off.
fan came on immediately!!!! weird!
anyhow. gauge was at minus whatever and resting below 50. water was warming behind stat(small pipes) and still cold in front(large pipe)
the fan stopped after about 5 mins of tickover.
temp needle not moved at all at this point.
blower air was lukewarm in cabin. 5 mins after fan stopped large pipe was becoming warm. replaced expansion cap. expansion pipe became warm.
after 20 mins, the temp gauge was at 50, just!!
engine now nice and warm and pipes all nearly too hot to touch. fan still off. temp nearly 60. cabin heat nice. went for drive, temp didn,t change and fan didn't kick in. all back to, a weird, normal!?!?
