The squealing is your belt, either tighten it, or replace it (I
would replace it as it has already lost allot of intergrity probably

I'm not sure if this has an autotensioner or a manual tensioner (if auto the auto tensioner will need to be replaced also

When I start my 2004 suzuki forenza sometimes there is a loud squealing noise that will stop if I rev the engine. It doesn't sound like a belt to me sounds more mechanical. It also sometimes makes the...


Squealing noises are more apt to be from belts, not mechanical parts. It doesn't necessarily have to be "a belt" per se, as the noise could, in part, be caused by an idler pulley. Open the hood and try to locate the sound. FYI I have posted the complete 2004 Forenza Service manual on FIXYA. Do a site search with those key words.

Tps on nissan quest makes loud noise when accelerates


As I look at your letter, which is very good, I might add, here are the few things that occurred to me.
The "loud squealing" should be a belt.
You have one or several belts, and if they get loose, or are worn out ( that includes the belt rubber getting old and hard) they will squeal like that.
However, the squealing also may be coming from one of the pulleys the drive belt or belts are attempting to turn.
If you have a bad bearing in one of the pulleys, you can get that loud sound like " a train".
If you are really careful, a "mechanic's stethoscope" might help you.
That is to take a really long screwdriver, and put the tip on each of the pumps or base of each pulley, and the handle end to your ear, and you can hear the bad bearing "scream" with the engine running.
Be blessed.

I have a gradually getting louder humming noise in the rear of my 1999 Astro van. Can you give me some problem posabilities?


Did you find out what it was? I have the same thing on my 1999 Astro van. It seems like an electrical issue and it varies when I press the gas. I'm thinking fuel pump. It used to make the noise and then stop. Now it doesn't stop.

Fast idle astro van


Check the base plate gasket under the throttle body, some time the gasket start to leak, and will cause a high idle, if possible with engine running get some water and pore it at the base of the throttle bode, you will hear a suction sound, that's the gasket, replace it.

When driving down the road my tires seem to lock up with a very loud squealing. If I let set a little bit and get back in car and put in reverse a little and then drive it goes again....but it seems when...


Sounds like your brake calipers are locking up your tires.I had a friend with the same car that had the same problem the next stop you should make is the auto shop.I would not drive any more until you get them looked at.Its not really the car that's warming up its your brakes one way that you can tell is if you smell a really strong odor coming from your brakes.When you put it in reverse your unlocking the brakes from the drum or disc.
