    I R&R the fan clutch Assembly,because I am getting a growling noise from the engine. The noise gets worse when you accelerate. I tried a tube to listen for the noise at the pulleys. I think it maybe the water pump because check engine light came on. What do you think it could be?

    If it is fine this is really sounding like a driveline balance problem or maybe a worn yoke or possibly even a bearing.

    It makes the sound when I am in park also. Sound coming from the engine.

    Does the sound die out in park or persistent?

    If check engine light is on we can just scan for error code and identify the fault. Most autozone shop does the scanning for free..

    the sound increases when you run the rmps up in park.

    Its hard to find out whats the problem by just trouble shooting like this. Please do perform a scan on your car.

Hi! Try using a tube pipe to sort out the sounds. This procedure is old school but still works. Pay good attention to the pulley and tensioner. The one you are hearing can be a bad bearing which will need replacement. Hope this helps and have a good one!

2006 F150 5.4, 4x4, Lariat. Intermittent excessive humming/fan noise from engine compartment


Sounds like the fan clutch bearing is locked up. Running in direct drive will affect MPG drastically. Its a 2006 so its time to replace it. See if the fan blade will spin by hand with the engine off or if excessive wobble is present at the bearing.

Loud noise from the drivers side engine bay area or behind pedals


Sometimes the A/C unit will make noise 2 different ways. The compressor pump requires oil to lube itself. An oil charge with the proper weight (there is a difference just like in motor oil) will silence the noise. Second, the compressor clutch can get a build up of rust. When the clutch is freewheeling, the rust will make noise until it is knocked off. Since the clutch is magnetic, a little oil wiped between the freewheeling edge of the clutch will silence it, and not affect clutch performance. Once you start getting a rust "bloom" it will require periodic oiling. Though both would be affected by engine RPM.

I would also look at the engine cooling fan. Its' speed is independent of the car motor, and will operate while driving or parked. It could easily produce a rotary noise. Also your heater/AC interior fan could be making noise.

I hope my solution helps.

Loud noise when I turn on the A/C


probably the ac clutch gone bad or at least the bearing. Is the noise increasing with rpm and is the pulley on clutch turning true and not wobbling?

I have a 1997 dakota 5.2 motor. Had to replace fan blade & clutch. Im putting a new water pump on now. if i still have noise what other things should i check.


Alternator, A/C Compressor, Power-steering pump, smog pump, idler pully(s).

I would pull the belt(s) and check each pulley for wobble or rough spinning.

Hope this helps

High pitched howling and screeching (yes two different noises). The howling appears to happen when the air conditioning compressor pulley engages. The screeching, my guess would be from the belt. Any...


When the AC compressor kicks on, an electrical load is placed on the alternator and the drive belt that turns the alternator pulley, if not tight enough, can cause the belt to squeal. Replacing the belt should help with that noise if the belt is stretched from wear. The screeching noise can be from a bad idler pulley, a bad belt tensioner pulley or a bad alternator pulley or a failing clutch on a very old ac compressor and rarely a water pump pulley. To check pulleys remove the drive belt and turn them individually to see if they can be tilted up down or sideways with play in the "bearing" of the pulley. Also, you may wish to visually inspect the clutch on the ac and look for melted black rubber around the bolts that secure the clutch to the compressor (stinks,smokes and melts these rubber areas if ac compressor clutch fails).

What would cause a grinding noise in the front part of a motor sounds like gears grinding


generally if this vehicle is equipped with a timing chain and gears that would be suspect...the chain/tensioners wearing out...possible water pump bushing but you should see a fan blade wobble or signs of coolant leaking from below...I have seen A/C compressor clutches coming apart that create one hell of a noise before they let loose.... even serpntine belt tensioners can have bearing problems and sound like hell. Good luck hope this helps!! John

I have noise at the front end i had it check and they did not find nothing they said i was wear of the truck does that sound right one more thing when i turn my ac on it makes a roaring sound when i mash...


for your first question, there are so many noises that can be found in the front end of a truck. You will need to be ALOT more detailed in your discription.
For the second one; when I first read you question I think fan clutch. Which would be normal for the truck. When fan clutches lock the truck can sound like a B52 airplane taking off.
BUT you say something about the blower motor, so I don't really know how to answer the question. You mean it's a noise inside of the car or a noise in the engine, or a noise only when the ac compressor is cycling in the on position?

My radiator fans are wobbly


Well its probably bent and a fan blade is hard to bend back. and make it right. My advise is to buy another one.
