2001 montie carlo fans wont cool off engine

Lifters tap because of low oil pressure. Or extreme amount of dirt. Either way it goes to the crank bearings. Replace the engine.

I have a 2000 Chev Monty Carlo we have replaced the transmission, water pump, rewired fan and tested for gage pressure. The problem is water is not circulating through the hoses. Any suggestions

check your gauge,,, there is a tool wheere u can check real temperature on ur engine from 1 or 2 feet of distance...

Change the thermostat and the coolat resevoir cap.These are the 2 main things for overheating problems. The thermostat sticks and the cap will let coolant escape from the tank, after a couple of trips the engine overheats. Also make sure your cooling fans are coming on. Physically pull the relays and all fuses, as the do lose contact.

spray with wd40 or liqid wrench let soak take a hammer hit the rotor around the front where it wont mess u rotor then hit at back where caliper is maybe it will come off

Hi, check the connection on your temperature sensor. If the connection is good, replace the sensor. The cost is about $11 at autozone. The sensor is located at the back of the engine, near the transmission. See pictures below. Use some water pump sealant on the threads when installing the new sensor. Please let me know if you have any questions, and thanks for using FixYa.

Hi;
If your engine cools down when moving fast, you either have a problem with your water pump or your electric fans that cool off your radiator and a/c condenser. This is controlled by a temperature switch, but these fans should kick on instantly when A/C is selected.

Better make sure the fan works. There is a switch on the radiator that turns the fan on when it gets to a certain temperature. It could be the fan or the switch. Your thermostat is not your cap, it's in a different location. (Usually at the engine end of the upper radiator hose) Get the leak check! A good garage can pressure test the system to see what leaks you might have.

if you have power there then the fuses are good or relays but if you have power then you ethier have a bad fan or ground wire also that fan should only come on when the ac is 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...
