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 fans on 2001 chevy malibu will not come on unless ac on

the relays control circuit is grounded by ECM (computer) . to check this make sure the is hot enough for the fans to be commanded on by computer and check to see if you have voltage at relay and it has ground from computer . you may need ECM.
good luck

Make sure you get the air out. There may be "high spots" on the engine that you can unscrew to let the air pockets t. Close this small valve when just hot water comes out.
Unplug the radiator fan and use jumper leads to test the fan operation. Use a scan tool to check for codes. If you get a scan tool that gives live data, see that the PCM sees the actual temperature of the engine after 5 to 10 minutes of running. It should see the temp. rising to 225 degrees farenheit.
Replace engine temperature sensor if the PCM doesn't recognize the proper temperature. You ARE going to compare this to the temperature gauge!!!
If all else fails, get the PCM recalibrated or flashed at the dealership.

Dash temp guage goes to red on 2000 ford focus dohc zetech


Because you have done so many repairs already I would most likely say that the gauge is defective. I would use a manual temp probe and probe the coolant temp after the car has reached operating temp. Coolant will be between 180- 230 degrees. If coolant temp checks out and you can see coolant moving in radiator and the vehicle does not overheat then you will need either a gauge or a coolant sensor. To locate the sensor it should either be mounted in the thermostat goose neck housing or the intake manifold.

Cooling Fan won't come on, coolant flows into overflow tank


there is a switch in the engine intake or cylinder head that controls the cooling fans. The switch is the one with only 1 green wire hooked to it. Turn the key to run, with the engine stopped pull this wire off and touch it to a ground( cylinder head, engine block) and the fan should start, if not look at the fuse, if it does you need to replace the switch.

Electric cooling fans will work.


The fans are actuated by coolant temp in the radiator. It is possible to have overheated coolant in the radiator, causing the steam, and your engine not overheating...the temp sensor for your engine is reflecting the engine temp, not the temp of the coolant in the radiator. You problem could be a bad temp sensor at the radiator...not allowing the fans to come on. Good Luck! I hope you find this to be very helpful!

Chevy Celebrity overheating


All you have is one or two fans? Have you checked or replaced the thermostat? The thermostat opens when the engine gets to operating temp, and allows the water in the radiator to flow through engine and the water pump pumps the water out of the engine back through the radiator to cool before it goes back through again. I check the lower radiator hose to see if it get hot like the top hose or you could take the lower hose of the pump to see if it is pumping. I would start with a radiator flush and do this a couple times, prestone makes a flush and Im sure someone else does. do that then change your thermostat, make sure when you put the new one in it goes in spring side down..

Have a 2002 cavalier Z24 and the cooling fan will not go on. Have a hard code on the engine saying Cooling Fan 1 Control Circuit. checked all the fuses and the relay, all are fine. what might the problem...


there are two coolant temp sensors on this car one controls the fans and one controls the temp guage in the car. one is located near the thermostat housing and the other is usually located in the block. the one near the thermostat housing usually controls the fans. also try to jumper the fan and make sure the fan is working.

1998 corvette water temp get up to 225 to 230 befor fan come on. where are the cooling fan control sencors located, not the relays


Fan wires go to relay, than after relay, they go to engine temperature sensor located on the side of the block. There is another sensor usually attached to thermostat housing. This would be coolant temp sensor. You can test both sensors with an ohmmeter or multi-meter

My 1987 Chevrolet Z24 Cavalier cooling fan will


since you have already tested fan and relay and both work, the problem may be the engine temp sensor. There are two sensors. One goes to instument cluster. This is engine coolant temp sensor, the other is engine temp sensor which is usually attached to engine block, sometimes they are connected to thermostat housing with the coolant sensor. You can pully the engine temp sensor and test that sensor same way as relay. (with mulitimeter)

Coolant temperature relay switch


Most vehicles use a coolant temperature sensor which is located near the thermostat directly connected into the coolant line, or near the thermostat housing, there are relays for the cooling fan which is usually located in the power distribution box under the hood.
