Cant locate coolant temp sensor on 02 jag s-type 3.0

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: I have a 2003 VW Jetta 1.8t that is overheating.

Assuming engine tune / mechanical condition is not the cause of the overheating:-
Ensure cooling fan is cutting in at the appropriate engine temperature - check operation of the fan controlling relay,
Ensure fan switching control temperature sensor is serviceable,
Ensure cooling system is filled properly, taking care to bleed out air where necessary,
Ensure coolant pressure cap is of correct rating and in serviceable condition,
Check coolant hose on suction side of waterpump is not softened and collapsing at engine revs above idle,
Ensure radiator core is not blocked or cooling airflow inhibited by insects etc.
