SOURCE: Radiator Fan's Run All The Time

There are 2 things that will cause this to happen. 1. The thermostat needs to be replaced and, 2. The coolant sensor can be bad. When I had this problem, I changed them both at the same time, she been just fine since then. Also, I had the check engine light on, and got the code from AutoZone (it's free!)

SOURCE: 1998 sunfire temperature gauges quits working as soon as cooling fan comes on and check engine came on P0118 code

You may have a problem with the engine temp sensor or the wiring.
The fan would come on if the computer lost the signal from the sensor rather than the sensor failing because of the fan.
Low coolant is another possible cause.

Why is the cooling fan always running when car gets warm on my 2003 hyundai elantra


It is easier to cool a warm engine that to cool an engine at almost over heat condition. So manufacturers run the fan as soon as the engine gets to operating temperature and that gives the cooling system more control of the heat in the system

I have a 98 sunfire. should the cooling fan on the radiator come on from the initial start up?


The engine cooling fan is designed to come on when the engine reaches 225-235 degrees Fahrenheit. That is the only time it runs. Do you get a check engine light?

My 2001 sunfire starts fine.but after i drive for about half hour it will stall and wnt start again for half hour.the oil light stays on when this happens.wassup with this?


This happened with my Sunfire. It was the radiator. The engine wasn't cooling, but the sensor wasn't showing that it was overheating. So the engine would start when it was cool, but as soon as it got hot, then if I stopped it wouldn't start again.

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.
