Question about GMC Envoy

I recently replaced the clutch fan on a 2009 Envoy but the vehicle is still making the same noise as before I changed out the clutch fan - does anyone have any ideas on what else the problem could be.

Check the A/C Cluch . This is a common problem on today's Cars .
If that is not it , It is most likely your Idler pulley for the Serpentine Belt , once they get some miles on them or a little dirt they start to be trouble . Hope this helps!!! Grant

SOURCE: 1995 gmc sierra clutch pressure problem

could be wrong here but sure sounds like its out of fluid at the "master cylinder" look near the brake master cylinder for a seperate little container for the clutch. bleeding is tricky because it is small and wants to run out of fluid quick. you have to keep adding each time you bleed. Hope I helped. Thanks

SOURCE: My air conditioner fan speeds have all stopped

Yes,it is the blower resister,it controls all the speeds to the blower motor,it is located near the blower motor,and it might have a wire harness that is burned up too,replace it,and the wire harness,and the blower motor,the blower motor is what causes the resister to fail,it draws too many amps,even though it might sound good,and run fine,it is requiring to many amps to run it.If this was at all helpful,please rate,thank you.

Sounds like you may have disconnected the battery. Does the rough idle only happen when the defroster or A/C is on? If so clean your throttle body with throttle body cleaner with the battery disconnected. When finished, drive it for 5 or so miles with the defroster / AC off to let the computer relearn the settings. This will solve your problem.

My engine is making clicking noises when I start it. This lasts for about 10 minutes.


Sounds like a lifter hasn't pumped up . Put an additive in the engine oil that quiets noisy lifters. Any auto parts store or even walmart has it.

Envoy cant get to water pump to change it. Removed grill exc but can't get radiator out and fan out


The fan and fan shroud need to be removed as one assembly. You will need a 34mm wrench to get the fan clutch removed from the water pump. Once the fan clutch is unthreaded and the bolts that hold the fan shroud to the radiator are removed you will be able to remove the fan clutch/ shroud assembly from the vehicle. You do not need to remove the radiator nor can you remove the radiator without first removing the clutch/shroud. You will notice that when you are removing it it will be a little tight getting around the inlet for the upper hose on the radiator . Once the shroud is removed trim a notch where the shroud was hitting on the inlet and I will make install a lot easier. If you have any questions let me know. Thank you for using fixya.com!

I have a GMC 2003 Envoy, each time i drive it sounds like im speeding but im going really slow , i need to change the oil could this affect that and what do i do about the sound


Difficult to know what sounds like speeding: engine, road noise, what ?

If the oil change were to help, you have bad, bad engine problems. I suspect you may have a wheel bearing that may have failed. This makes a lot of road noise, alters with vehicle speed and NOT engine speed (drop to idle, noise the same).
There is a possibility of transmission slipping. this lets your engine speed up, but not actually move the car.

There is a third common issue and that is FAN. When your fan clutch fails, is locks up a normally free spinning (somewhat) fan, as if the vehicle needed max cooling... This noise follows engine speed, the vehicle seems to go just fine, but huge noise.... This sometimes is called Jeep fan noise, as many of those used to have direct drive fans.... If this is your case, the fan clutch gets replaced, not huge $, but more than it should be.

CLUTCH FAN IS MAKING NOISES RPM IS LOW AND WHEN DEFROST IS ON IT IDLE UP AND DOWN


the fan clutch is electronic and has most likely gone bad we replace them at work on a regular basis also this vehicle is bad for throttle body coking large amount of carbon build up at the throttle plate and should be cleaned good replacing the fan clutch and a throttle body service will take care of your problems

2004 gmc envoy. has a 6cyl and a serp belt. the center pully off set to the left (i think its a water pump) has a bad wobble and making a horrible noise. Not over heating and no leaks. should i just change...


If the fan is attached to it than it is the water pump making the noise and it will need to be replaced. If the fan clutch is not attached to it than it is either the idler pulley or the tensioner pulley. The tensioner is on the passenger side (left) of the front of the motor.

I have a 2006 gmc envoy xl that sounds real loud like a jet when you start it up and when excelerating it gets louder and louder. Could it be the fan clutch or the relay any answers anyone


Fan clutch failure is common on these........and very costly to replace. With the engine cold, engine off, reach in and turn the fan, it should turn with minimal resistance, if it has heavy drag, or wont turn at all, it needs replaced.

I have a 2002 gmc envoy bringing up codes P0440 and P0495 does anyone know what these are? it seems to run fine but it makes an awful noise like a jet plane when you accelerate and the check engine light...


P0440 - Evap system large leak. This code has a real common problem of the fuel fill cap either loose or the seal or check valve bad in the cap. There are also some hose and lines from the fuel tank to the charcoal canister that can be the problem. But most common is fuel cap loose or bad.

P0495 - Cooling fan rpm too high. This code sets when the control module has commanded the cooling fan rpm to zero and the rpm exceeds a predetermined amount. Your vehicle has a clutch driven cooling fan that the control module regulates through a solenoid valve. Most common problem is a stuck fan clutch which is consistant with the "jet plane" noise you are hearing. The clutch staying engaged when it should be slipping or "idling"
Good luck
