Ive already changed coolant temp sensor,cooling fan switch, thermostat, still the fans wont come on unless I make them
Hi Matt ,
In this case if after pulling fuse fan get start it means all the wiring, relay and fan is fine you just need to replace the thermostat/Tempratue sensor sensor, it comes on the radiator.
Thanks

SOURCE: cooling fan not working
The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.
SOURCE: I am trying to change coolant temp sensor
have you checked you fueses and relays?
the coolant sensor is located
Under hood, driver side, rear engine area, mounted on intake manifold

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

Hello. I understand your frustrations as I too own a 2001 monte carlo and have had the same problem...along with several others. My engine temp gauge would show ZERO degrees because of the bad coolant temp sensor. So I replaced it with one from autozone (BIG MISTAKE) The one from autozone was **** and gave the car a different problem. The fans would not run while the engine was running and would run when the engine was off until the battery rundown protector would shut them down. this lasted about 2 weeks during which I had to keep my heater on (in the middle of summer) to keep my car from over heating because my fans wouldnt run. The autozone jerks said "if my temp gauge was working then the sensor was doing its job" and that "there is another problem" Well I finally called the dealership and they told me that autozone is junk and to try advance auto parts and to get the next one up from the cheapest...this is what they use...and NASCAR uses. It was a few dollars more (around $25) Problem solved. However a few months later the cooling fans went completly out..this was due to them experiencing such high temperatures for 2 weeks. I replaced them with ones from a salvage yard for $50. Dont let this happen to you...

The cooling fans work with a sensor. It has to reach a certain temperature in order for it to work. Maybe it is not the fan. Fan not coming is definitely caused by a faulty thermostat.
