Possible leaking head gasket.
SOURCE: Cooling fan wont work
The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.
SOURCE: cooling fan
Whoever told you the temperature gauge on cavalier is normal 3/4th is the lie. It is however in operating temperature range but on the hot side. Have you flushed your coolant and replaced thermostate, and gotten air vapor locks out.
SOURCE: can't locate the cooling fan sensor or relay.
the radiator fan relay is located behind and slightly lower than the r/f headlamp.best way to get to this is by removing right side of front fascia out enough to get behind it. this will give you acsess to the relay.i work at a jeep dealer and have done this many times.
SOURCE: 2001 Oldsmobile Alero overheating
I have an 02 olds alero (142000) the radiator fans are not working, therefore overheating. I have replaced the thermostat, water pump, coolant, what causes the fans not to work?
SOURCE: 2002 pt cruiser - overheating - collant is up,
SOUND LIKE COOLANT TEMPERATURE SENSOR .BUT FIRST HOTWIRE COOLANT FAN USING JUMPER WIRES TO BATTERY IF FAN RUNS ITS GOOD IF NOT REPLACE FAN MOTOR..ALSO HOT WIRE RELAY TERMINAL 86 TO BATTERY POSITIVE POST AND 85 TERMINAL TO BATTERY GROUND POST USING JUMPER WIRES.IF IT CLICK ITS WORKING IF NOT NO SOUND REPLACE RELAY.IF ALL IS GOOD.THEN THE COOLANT TEMPERATURE SENSOR IS BAD.

Would that keep the fan from coming on at the right temp and make it smoke like it's burning oil when the temp goes up
I think that is most likely not oil but coolant burning in the engine due to a leaking engine cylinder head gasket. Coolant has a kinda sweet smell when it burns/vaporizes
