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

Yes, it's probably the PCM. I had the same problem, and upon replacing the PCM it started working again. If your cooling sending unit is new, and so many parts of your fan assembly are new, it's probably not receiving the signal from the sending unit. Hope this helps.

SOURCE: overheating fan will not run ! I change cooling

there isa short in the wiring somewhere,which a shop can check for you,or check your thermostat. after 20 years i still have to make sure tat i dont install it upside down. which is easy to do if your in a hurry. my bet is that the wiring going to the coolant sensor has a bare spot and grounding somewhere.

SOURCE: engine is getting hot and radiator fan will not

You should have a check engine light on if your coolant temperature sensor is bad. It could be your fan relay. It's position should be located on your fuse box cover(s). To check the fan itself, unplug it and notice that the black (or darkest) wire is the ground, so you can hook your jumper wire to any metal part of the car. The other wire goes to the positive terminal of a car battery. Good luck.

2006 chevy hhr hvac blower/fan

The fan is normally used for both heating and cooling. Check the owners manual for the fuse location and see if it is blown. If so, replace it and try the fan again. If the fuse blows again, the motor is probably seized and will need a mechanic to oil and free or replace it. If you can get to it your self, BE CAREFUL, and touch the motor when it is turned on. if it gets hot without turning, it is probably electrically OK and seized. If it does't get hot or hum and the fuse is OK, Its either bad or has a problem that will need to be traced. Best to take it to a GOOD mechanic that you trust. Trouble shooting can get complicated.

My 2006 hhr temperature goes up too often.

There should be some relay controlling the electric radiator cooling fans. Usually 2 heat sensors are on the motor, 1 for the dash gauge and the other for the fans.

You are trying to cool the transmission when the truck is in gear. When you go to Park or Neutral, the trans is freewheeling and the engine can also rev up slightly. Both of these actions will help bring down the temperature.

You need to have the electric radiator cooling fans checked. Sometimes they are built with 2 speeds and the high speed may not be switching on.

Also, some engines have a cooling fan clutch which is suppose to grip better when the engine heats up. This function can be checked with a timig light. If the clutch on and the fan clutch slips too much, it will overheat.

My 2007 Chevy HHR 2.2L, coolant temp sensor is reading that the coolant temp is 20 degrees warmer than the outside temp after sitting for over 12 hours and the operating temp gets to 214 degrees without...

Sure the engine coolant will be warmer than the outside temperture and if the car has been sitting a long time in cold weather and the outside temperture warms up it could be the other way around. The coolant temperture sensers aren't real accurate as they are a relaitive senser beween hot and cold and the numbers reported don't have to be real just the change from hot to cold and the reching of the coolant to the operating temperture. Noe it the senser doesn't read the opertating temperture coprrectly you'll have all kinds of problems. The therostaste will try to set the temperture of the water to it's set temperture and can open or close completly to get 195 degrees F. Many times if it's too cold then the stat is bad and needs to be replaced This shows up in alot of cars first thing after winter and the first onset of cold weather when the daily tempertures vary the most from day to night.

Cooling fan quit running and i cant find relay

Relay may be ok, check the temperature sending unit that signals the relay to run the fan, it may just provide the ground for the cooling fan! Temperature sensor for the cooling fan circuit!

I have a 96 ford probe and it keeps over heating rad. Is full the over flow is full and just put in a new thermo in it please help

You have an Electric cooling fan. Most cooling fans have 2 speeds and if the high speed is not working, eventually the low speed will not keep up and you will overheat.

The cooling fan depends on Electric relays and a temperature sensor on the motor. This sensor on the motor can be different than the sensor that makes your dash gauge work. Go to Autozone or Orellys for a free scan and view the part you need.

If possible, when the engine is cold take off the Radiator cap and have it tested for the amount of Pressure it will hold before letting the coolant go to the overflow. When the engine is running turn on the heater in case you have an airlock in the water system.

Cooling fan for rad not working.. if relay is

either the relay has shorted out or the coolant temperature sensor has failed. start witht he relay, install a new one and see if the situation improves, if not then do the temp sensor.
