I've noticed last year or 2 years ago that if I turn my climate control past 80 sometimes the coolant temp gauge drops and the fans come on and stay and check engine light comes on but when I scan there is no code, anybody else get this??? 06 rwd 4.6
coolant level is fine, but never changed t stat might just go ahead and do that. I know on my 03 cts the t stat is stuck open and the light stays on and that t stat is too much for me to change so I'll deal with it but on here it doesnt look too bad to change. Might as well flush system even though I flushed it last year
t stat is under the throttle body. if you remove tb you will have acess to it. I need to make time to do mine just didnt think it would cause fans and temp to drop, I might change sensor since i will be dirty lol
my brain farted i meant intake and air box. too much jp-8 lol. and i doubt its the sensor anyway now that i thought about it, i do wanna polish the tb but i have another project to tackle this weekend............ the damn freaking diff bushing again, i went poly this time(rev shift)
