Fan clutch screws on to the water pump. You can loosen it with a big adjustable wrench (it is about 1 1/2" or 1 9/16" hex). Leave the bolts for the pulley in so you could wedge a screwdriver under a bolt head to keep the pulley from turning. Give the wrench a hard **** to loosen and it should turn off by hand. Right hand threads so you will be turning it counter clockwise to remove.

SOURCE: How to replace the headlights on my 2003 GMC envoy.

The headlights on the envoy are the easiest parts of the car to repair. You just pull the two tabs at the top of the headlights, screw out the bulb containers and you are good to go

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.

I replaced the clutch fan on my gmc 2003 envoy. But I still have the same problem, the noise is so loud, is there a computer that controls the fan?


you mention you have a clutch fan then you don't have any electrical control on the fan.
remove the belt to see if it 's the problem could be water pump bearing or else
hope it helps

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.

After replacing the fan clutch and water pump do i have to reprogram the computer on a 2003 gmc envoy?


No! there is nothing to reprogram. The sensors in the coolant system and the temp sensor for the fans dont need to have anything done to them. If you are not getting any check engine light, you are good.

I replace the fan clutch and the water pump and its still making a clicking noise, what can this problem be?


Maybe the fan is hitting the shroud. Did you check the serpentine belt for fraying or damage?

Replace flan clutch and water pump and alternator but still makes a clicking noise, what can cause this problem?


A brand new out of the box fan clutch did this to me. Ticks are driving me crazy. It's probably your new fan clutch unfortunately. Mine was purchased at Autozone if this helps.

GMC Envoy 2003 overheating


Your fan clutch could be going out...iin other words, it may be turning, appearing to be fine, but not fast enough therefor, not cooliing the engine enough.

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.

2004 gmc envoy engine tapping sound, it has plenty of water/antifreeze, and plenty of oil.


We have the same tapping sound on our 2003 Envoy six cylinder engine. I believe the sound is coming from the radiator fan clutch assembly. When the engine reaches its operating temperature and the fan clutch engages, the tapping sound goes away.

Loss of power


For the person with the loud engine and poor acceleration, the problem is likely the fan clutch. I think it is about 800$ to be repaired.
