Looking for some help?? i got a 96 civic with a d16y8 and am having this horrible squeaking sound coming form around my timing belt and alternator. I know that is not my alternator or my power steering because i have removed the belts and it still does it. I changed my water pump and timing belt pulley thinking that was the problem but still nothing. right after i changed the parts i got it back together and it seamed to be good. i let it sit and get to running temp and no sound. I drove it about 15 mile and turned it of when i come back out i started it up and the squeaking was back. i notice that when i have a load on the motor the squeak goes way. but when i let off form accelerating it comes back. any help would be great thanks!!!

i would say check your idler pulley

Like my timing belt tensioner?

Former User

Did you remove the A/C belt?

Berge9798

yeah i sure did all my acc belts where taken off the pulleys

Former User

This would be your prime suspect.

Berge9798

i already replaced it

Former User

Does the sound go away when the clutch pedal is pushed down?

Berge9798

no its not anything with my trans. its on the timing belt side

Former User

Have you tried to pinpoint the noise with an engine stethoscope?

Berge9798

no not yet its pretty loud so it should be easy to find

Former User

You know the general area where the sound is coming from, but not exactly. A $5 stethoscope will help you precisely pinpoint the noise so you are not guessing.

Berge9798

is there anything u might think it is

Former User

I have already speculated too much. Engine noises can be tricky. Don't guess. Take the time to properly pinpoint the noise.

Berge9798

yeah thought it was water pump but that was not the problem so im out of ideas. have u heard of a oil pump making a squealing sound?

Former User

Possibly. Seriously, my engine stethoscope cost me $3 at Harbor Freight Tools.

thats what i will have to do

or just re tightin all your belts....

is there a bad spot in any of your belts?

and is your p/s pump bad?

Timing belt tension is too tight so the tensioner is screaming from too much load. loosen up the timing belt a lil bit and it should go away. Seen it happen quite a few times.

Berge9798

ill give that a try

Former User

If you tensioned your timing belt as described in the service manual, then it should be fine.
