hello everyone i amnew to this and i have a 1996 cadillac deville v8 with overheating issues. everythin has been changed, head gasket, radiator, etc. i realized my fans dont turn on and a friend of mine aid it was the coolant temperature sensor that was bad and wasnt lettin the fans turn on. but when i turn on the ac both fans turn on. anyways i bought the sensor and i cant find the location of it.
any help
greatly appreciated
thanks

 

Possibly in the radiator itself. Be aware without climate control on, the fan does not turn on till approx 220 degrees F. To confirm operation, put a cardboard sheet in front of radiator while it idles in the driveway. This should speed up fan engaging. When the word overheating is said it means to most mechanics that the system boils over and the gauge goes to red. Running too warm means the temp gauge reads higher than before. On a Northstar the bleed hose from the engine to the holding tank can become plugged enough to cause circulation issues. Make sure this small hose is open as well as the nipple on the engine is not plugged.
