S40 2.4i belt squeak

Post by Katethes40 » Mon Jan 07, 2019 8:57 pm

Hey! First post! Hoping to get some help. Any and all is appreciated.

I have what sounds like a belt squeak. Not at all the PCV squeak sound. I should mention the PCV squeak occurred in August and was replaced.

Squeak has primarily only occurred at idle. This morning when I started it it was making a humming when I revved it a bit. This is extremely unnerving for me.

Sometimes it does not squeak at all, but it always goes SQUEAAAAAAAAK when I turn off the car.

I took the car to firestone and they said everything is fine.

Any help? I have no issue replacing both SERP belts and tensioners but I’m terrified it might be the timing belt or water pump. If my car dies I am absolutely screwed.

Go someplace else and get a second diagnostic. The big incorporated persons don't get the best mechanics because they woun't pay for the best.
