the driver side fan in my 2002 ss is no long working i have to keep a/c running so the right side fan can keep engine cool . but when the a/c is off the car over heats a little so can some one tell me if its the riley thats bad or do i have to change the whole fan system also there is a lot of pressure in both hose i think thermostat might be bad also . can some one please help me.

 

Your radiator and heater hoses will be tight because they are under pressure when you engine is at operating temperatures. This is normal. Your antifreeze at the overflow bottle should be at the "hot" level. I would replace the fan relay that supports the non-working fan as you indicated only 1 fan works.

 

yes ok i wil go ahead and replace the relay for that fan to see happens thanks .

 

OK so I have a similar problem ... a couple months ago I realized my car was over heating while in traffic ... first thing I did was check the fuses nothing was blown then i went to autozone and they were nice enough to loan me a relay so I could swap out one after the other and no changes. Then I bought fans and was going to replace them today but I wanted to get my ac working first so I replaced the high side port that was leaking and recharged the system and ac worked fine and was sitting in the parking lot idling and realized my temp wasn't going up so i popped the hood and both fans were running. So I'm a bit confused it seems to me it would be a sensor fuse or relay or g** forbid the pcm or bcm any one have this happen to them or have any ideas? its a 3.4L btw ... thanks in advance -Rob

 

thats kind of weird lol.....

 

did you replace your relay?

 

i didnt have to replace them. they work fine but the guy at auto zone said the fan motor might be the problem. so what you guys think. i also replace the thermostat it was bad.

 

can you run power to the fan to test if its the motor or not?

 

yes auto zone told me to do the same thing you said now, im waiting for the motor to cool down a bit before i put my hands down there . they told me to switch the plug from the one that works to the one that dont work to see what happens.

 

thats a way to do it. i thought you could just run a 12 volt and ground the motor, but there way im sure is safer, and would also work.
