ExZion Posted January 24, 2006 Report Posted January 24, 2006 What is a normal running temp for a cutlass supreme 3.1l?? My car will not overheat but it will run to like 215 and still no fan?? it wont go up or down just hover there? is it normal for the fan to not kick on. i have already checked the relay and the fan and they both work? WTF do i do next?? Quote
Prospeeder Posted January 24, 2006 Report Posted January 24, 2006 Turn the a/c on and see if the fans kick on, they should only kick on at abnout 220-225 or somthing, 215 sounds about perfect, if its cold out they may not ever kick on Quote
ExZion Posted January 24, 2006 Author Report Posted January 24, 2006 yeah one kicks on when the ac Turns on. but the running one NEVER turns on??? and yeah i guess it gets to around 220-225 because the needle is almost straight up?? Quote
Crazy K Posted January 24, 2006 Report Posted January 24, 2006 ExZion, Are you talking about 3.1 or 3100? your profuile vehcile being a 3100 powered 94 CS? info is still the same, however... my bros 94 CS is the same way. It has to get just a bit hotter for the fan to kick. The drivers side fan will turn on when it gets slightly hotter, and the passenger side one goes with the ac. (in fact, my expericence with w 3100 in a 95 ciera shows that the drivers fan turns on much earlier with ac on than off, something I have not observed in the 94 or 95 CS.) Try blocking the radiator with some cardboard to make it run a bit hotter, just to test. If a sensor is out of spec.... the coolant sensor beneath the throttle body (by the thermostat) is the one that tells the ecm the engine temp, and kicks the fan on. The gauge uses a sensor located in the corner of the rear head, on the drives side, by the firewall. Quote
THe_DeTAiL3R Posted January 24, 2006 Report Posted January 24, 2006 Let it run on the spot, with the hood closed. Takes a good 20+min until my engine gets hot enough for the fan to kick in. I dunno what temp it is, but it's like just over 2/3rds on the guage. Quote
Guest Anonymous Posted January 24, 2006 Report Posted January 24, 2006 my car always runs halfway between the 100 and 220 ticks... sometimes if im in traffic it will run up to 220, but i've never had my fans kick in. Quote
