hey everyone moving this into the thirdgen section...
Hi everyone, well I just got my car back from the autobody repainted etc. Ok so I reinstalled my fans and the whole nine. I had originally removed all that stuff to make the painting of the car easier for the painters.
well my primary fan does not come on when the car gets hot. My Heavy duty cooling fan does kick on at 240 like is suppose to but the primary does not kick on at all. I plugged in the scan tool into the ALDL and turned the key to run and as I found out in the book that energizes all relays (except the fuel pump) and that turned on my primary fan. So the fan motor is working.
Now I know what you are thinking its the coolant temperature sensor
at the front of the block. well I changed that sensor about 8 months ago with one from autozone it was a "Wells" brand. Now I am questioning whether that was wise or not. I also changed the heavy duty coolant fan switch
at the rear of the passenger block (again with a wells) and finally I yesterday I changed the coolant temperature sender
(the one the sends readings to the temp gauge)
again is not kicking on
. So either my guage is messed up and or the sensor is messed up and or of course one of my wires is bad from what I have gathered at this point.
Does anyone know if there is a way to check the temp that the sensor is registering? I read that a thermometer is an option (maybe I can go buy one at pepboys or something)
Any other suggestions would be greatly appreciated
