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 wont turn on

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...

Looked it up in Chilton's, confirmed in http://www.obd-codes.com/trouble_codes/

P0481 Cooling Fan 2 Control Circuit Malfunction

Each fan will throw a different code. See 3 fans listed for your model. Here's a link for the wiring schematic: http://www.chiltonlibrary.com/content/images/WD/GM/014/WD_GM_014788.pdf


Best of luck.

SOURCE: 2001 Impala Cooling Fan Not coming on ever and car

Cooling fan relay switch (in the fuse box uner the hood). Look for othger relays in there that are the same type number (they are all marked). If you find one that is the same as the cooling fan relay, then swap the two relays and check. (Turn on car and turn on A/C ... fan will start ... or not).

Fan motor could be bad (most likely).
If you remove it yourself, don't scrapr the radiator fins with the fan blades.

Hope this helps!

SOURCE: 2003 impala 3.8 cooling fans not coming. repaled

Check the coolant temperature sensor, it may have dirty contacts which is an easy job to fix. Signal from the coolant sensor indicates to the ECM that the engine is at running temperature and for the ECM to reduce the amount of fuel from the injectors (always a rich mix when warming up). (A little while later the thermostat should open allowing hot coolant to flow via the top hose to the radiator) The ECM rthen triggers the (5 pin) relay and the fans then come on. Check also the coolant relay fuse.

Ck engine light problem on 2001 Impala


Well the code is for the circuit - the computer commands the relay to turn the fan on and it doesn't happen.
The computer provides the ground for the relay.
If you have replaced the relay and the fan and the fuse still blows, I would look for a problem in the harness between the fuse box and the fan, including the ground circuit for the fan.
The fuse for the cooling fan is usually a 30amp marked "cooling fan" in the fuse box in the engine compartment.
Do you know what the 25amp fuse that is blowing is for ?

Hi!!
I you are looking for the cooling fan relays, they are located on the Power Distribution Box on the engine compartment, close to the battery. They should be labeled Cooling Fan 1 and 2.
Good Luck! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.
