Most of the time when an ac compressor is going bad it will make the noise you are speaking of. A quick way to check it if it makes the noise even when setting still is to pop of your serpentine belt and if there is no longer a noise it is most likely your ac compresor. If it is the ac compressor it will most likely lock up soon and the car wont start but if you can live without ac a bypass pulley is a quick and cheap solution.

First question. IS IT NOISY ONLY WHEN THE A/C IS ON ? If yes , its the compressor, if not could ne the A/C compressor clutch bearing. Best found using a " mechanics " stethoscope such as a doctor uses to pinpoint the noise. Hope this helps

My Mazda Verisa has just start making a grinding type noise when it's turned on. It sounds as if it's coming from the fanbelt area but I'm no expert at all. I'm thinking it's either a worn fanbelt, maybe...

A grinding, gritty noise usually means a bearing is worn out. The best advise is drive it straight to your nearest good mechanic and get it looked at!
If the bearings on the water pump collapse the timing belt could slip causing VERY expensive damage. Might be worth getting the timing belt changed anyway while he's got it off.

Does the 98 cadillac deville have a timing belt or chain

My book shows 3.0 ltr 1997-01 "V" engine with a timing belt recommended change at 100.000 miles or 60.000 miles under adverse conditions. It shows 3 idler pulleys that should be changed as well and all the cam and crank seals should be replaced as well because oil is the main killer of timing belts.. While you may consider the extra cost to be a burden you will not think so when you get 100.000miles trouble free in the timing belt area . Do not replace any of the items and you run the risk of all that work again in say 30.000 miles

I have a 1999 Buick LaSabre 3800cc engine V-6 with 130,000+ miles on it. It recently developed a unusual sound which seems to come from the front of the engine compartment (belt area). I had a very good...

fire your mech,
then find a ASE mech (see sleeve?)
he is incompetent.
this is the proof
When the tension mechanism is lifted (pressure taken off the belt) the sound goes away.

no real mechanic ignores this simple hard fact.
take to any ASE show him this check above,
he will find it , in under 1hr. I promise you.

Honda Accord metal grinding sound, esp when starting car when cold

A timing belt usually makes a loud squealing noise (like a 'shriek/scream') when it is worn or slipping, not a grinding noise.

A quick check - before you start the car - is to pour some water onto the inside of the belt where it goes around the pulleys. If there's no noise at start up, you know it is the belt at fault (or the metal pulley/s are worn).

There are kits to replace the timing belt (and bearings). Have a look on Ebay:
843results for accord v6 timing belt

If the noise happens before the car moves - it obviously can't be your brakes. When backing up the noise may appear louder simply because your head is turned ..

If the noise is actually coming from a wheel, it possibly could be the backing plate on the brakes - the thin disk behind the brake may be rubbing on the rotor.

However.. a grinding noise ... if it is coming from the front of the engine in the general area of the timing belt be very wary - if a bearing or the belt fails, your engine will be history.

Why not give a mobile mechanic a call? Those guys are usually quite good and a lot cheaper than a workshop

Loud chatter on start and rattle from timing chain area

The timing chain area also takes in the alternator and water pump. To isolate the source of the noise, use the old mechanics trick.

Place a 3 foot 1/4 inch brass rod against the flap at the opening of your ear and push until it closes. Place the other end of the rod against various engine components and listen. The noisy problem will conduct the noise up the rod to your ear and you can hear quite precisely where the problem is. Much safer than laying your ear all over a running engine.

You can also loosen the fan belt and run the engine without alternator or water pump (briefly) to see how that affects the problem. Chatter on start makes me think of starter and Bendix gear problems. Sounds like a 2 person diagnostic team to me; one to start the car and one to listen and probe.

Don't know if Subaru Forrester has an engine that has valve interference at piston Top Dead Center. If it is and the timing chain breaks, you are looking at major $$ to recover.

I have ratlling sound coming from the timeing chain area worse when first started

This sounds like the tensioner is broke or came loose, this is something you need to have looked at, if the chain jumps it will cause piston to valve damage, heres a picture to show you what im talking about more clearly, also i would remove the belt and run the engine to make sure its not a pulley or the ac compressor clutch making the noise.i circled the parts that may be cause the timing chain to be noisey and also the ac tensioner, hope this helps,fb714f4.gif

Hi, i am using a Honda Civik EK3 1996, recently i changed Clutch / Pressure plate and timing belt, But now i am getting a Grinding sound (very noisy grinding sound like TV channel is not tuned ... ) when...

You may have to do some testing...if it is coming from the belts, start disconnecting them, don't drive the car since you will loose the power steering, but see if the noise still exists. Then if it does, is it coming from around the timing belt area, which brings me to my next question, has the timing belt been changed? Even if it isn't the area of noise; it needs to be done, and the water pump has to be replaced at the same time...location of the grinding noise is important in order to diagnose properly.

Suski sidekick wont start HELP!

Turn the key to the on position. You should hear the fuel pump make a whirring noise.If not, the pump failed. But I don't think it's the fuel pump. It may be the idle control valve tha'ts dirty. this can be cleaned with carb cleaner while running at about 1200 rpms. Spraying into the fuel system to the sides diretly at the holes in the sides. remove the air duct work to do this. What I think happened that you had this problem before . Or the crankshaft position sensor went bad. When you were climbing up the hill your timing belt may have broken. It makes a rough noise when it comes off. check the timing belt . If thats the problem replace it, and then clean the idler control valve as explained. If thats not it. Check the crankshaft position sensor. Try to get a code if possible.At any parts store for free.
