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.

Have you double checked the electronic switch type thermistat mounted on the radiator that senses the temperature of the anti freeze. You can jumper around the switch while the car is started and the fan should start running (watch your fingers).

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.

Need to find location of coolant fan relay and sensor for 1990 pontiac sunbird ?


if your rad coolant fan is not working check the fan itself as this is a common problem on these cars. disconnect the plug from the fan motor and run jumper wires directly from battery to the fan motor terminals. if the fan doesn`t run replace fan motor. if it does run the check fuses then fan relay. the relay is in the relay box, the coolant sensor for the fan motor is in the head that goes into a coolant passage that has a 2 wire connector.

Cooling fans are not coming on, what could be the problem?


Either the temp sensor is bad, or the relay is bad. or the fan motor is bad. Or you have a blown fuse.
Look for fuse first.... To test if fan motor is bad disconnect the connector to the fan and jumper it to the battery.if it spins it's good. the other two. use a component locator to find their location and replace. they are inexpensive. Temp sensor is in the cooling circuit (radiator...maybe next to thermostat) the relay will be in a fuse box under the hood.

What did I miss?


If you can disconnect the wire coming from the fan and connect directly to a 12V source, you will learn if your problem is downstream from there or if your fans are blown, which is unlikely. Check your wiring continuity as far as you can with an Ohm meter.

Radiator fan stopped working, car over heating


unplug the fan at the connector,, use jumper wires from the battery to see if the fan works with direct current, if it does, check the relay for the fan in the under hood fuse box, and also the fuse itself

I HAVE 1995 CHEVY CAPRICE CLASSIC AND IT KEEPS OVERHEATING. I CHANGE THE THERMOSTAT. THE MAIN PROBLEM I AM HAVING IS THAT THE COOLANT FANS AREN'T WORKING. I REPLACE THE RELAYS AND TESTED THE WIRING...


Check for power and ground directly at the cooling fan connector (the red and black wires). You can either jumper across the relay or with the key on, disconnect the coolant temperature sensor (2 wire connector near the thermostat housing, usually yellow and black). This should override the computer and energize the fans. If you have good power and ground at the fan connector, then the fan motor is no good. If you don't have power and ground there, it's a wiring issue from the relay, the relay itself, or no power to the cooling fan circuit (fuse).

Fan has stopped working causing over heating, what is the most likely cause


There are 3 possible things;
The fan motor itself
The coolant temperature switch, which operates the fans, usually screwed into the engine block near the thermostat housing. Have to drian radiator to change it.
The relay-- It's a small black square shaped object, some are located in the fuse box in the engine compartment, and some are mounted on a bracket on the firewall, passenger side.
Could be in the wiring that connects these components.
To check the fan motor----- disconnect the wire plug from the fan motor, use jumper wires directly from the battery to the connector on the fan, If the fan works, then either the temp switch is bad, the relay, or the wiring.If the doesn't work, that is bad and needs to be replaced.

My 2002 s type jaguar doesn't heat. the fans


Probably the heater control valve, had same issue, started with one side not hot, then erratic, hot then cold while heat is set to hot, now both side are cold to lukewarm. diagnosed as heater control valve, common for jag s-types and x-types. located on the passenger side, down low the side of the radiator, it has several hoses into and out of valve, and a electrical connector.

Overheating Jag???


Chances are you have an electric fan that is not coming on when the car isn't moving so you have no airflow through the radiator. Check for fan operation. If the fan is working fine, you may have a faulty water pump. Some Jags had water pumps with plastic impellers and they came loose inside. You will have to remove the pump to check this, but if the fan(s) are working this is a very good possibility.
