Remember, your alternator and power steering pulleys are in that area too. With the power steering, if the pump goes bad it could sound like the pulley, not normally but I have seen it. And all the pulleys in that area will sound the same. Because they are so close to one another it makes it hard to tell which one it is. Turning them each by hand, as mentioned before, will give away the bad one!

 

i will give that a shot next time but i have to wait until the car is cold or something

 

update: i had replaced the altenator with a 125 amp and painted it, still squeaks. it deff sounds like its coming from the belt tensioner, put a metal screw driver to it/ear and its the loudest

 

OK so I did the squirting test at work and I hit the belt. The squeak went away. For mmoments. I hit the back of the pulley area and it stopped. The pulley is fairly new tho....

 

I also used my replacement belt and still it squeaks

 

I checked back at the details on this thread. First question, have you removed the belt and ran the engine to see if the noise goes away? If it does go away, it confirms if it is belt/pulley related. Second question, have you taken the belt off and spun the pulleys by hand, looking for odd sounds and/or play/slop in the pulley?

Lastly, the L36 3800 is known for an issue that if you don't have the O-rings properly installed on the PCV, it generates a noise commonly mis-diagnosed as a noise alternator.

 

Hey thanks mr. Jason for responding I haven't done the belt off test that will have to wait till Sunday morning. When I had the tensioner off I spun the pulley but nothing squeaked

 

OK. My guy says that may come to a PCV O-ring situation. Hopefully the belt off test well fruit some answers

 

ok so heres an update, i went and ordered a new pulley and a new gatorback belt, if these divdnt do the trick there was gonna b a bigger issue because i ran the car without the belt and there was no squeak, but when i changed them out im glad to say there was no more squeaking, thanks alot guys

 

If you have your belt start squeling again be sure to check the alignment of the pully. If one of them is off it will sometimes cause a squeal.
