Hi everybody! I have this situation with my car. I hear a high pitch sound in my engine bay when I'm pressing the gas mostly on low gears. It happens between 2000rpm-3500rpms and pass 3500rpms the squeel will disappear. I was thinking it was the belt, I was gonna tighten them but I don't have any tool to do it.. so I took it to the shop and they said my belt are tight(which I believe it is because I checked it myself) and would not try to tighten them more because they said that it may break or create more damage to the car if they will tighten the belt more that it needs to which I understand. So they came to a conclusion that maybe its the transmission so they recommended to flush it and replace with a new fluid and include a the SLICK 50, I agreed because I know that my transmission fluid needed to be change anyways(past 60,000 miles already). The thing is when they change the fluid the noise is lessen but it still there, the noise is very little now and still in high pitch. What could this be? How to eliminate this? Thanks guys!

My car is a 2001 Honda Accord Coupe LX 4 cylinder

 

try being a little more specific. What kinda noise is it and what part of the bay do you hear it from?

 

left side of the engine bay

 

Spray some window cleaner on your belt tensioner and see if the squealing goes away. If it does replace it.

 

Don't use anything but Honda Transmission Fluid in your tranny:doh:

 

Why can't you figure out where the squeeling is coming from yourself? I don't get it.

 

It because I can't judge where the exact problem is if the problem happens only when the car is moving and you know I can't look at the engine bay when the car is moving. Anyways.. even the mechanic where I brought my car in can't figure it out, and I'm not a mechanic. I just know a little something about fixing cars.

 

Take a peek at your alternator, does it only make noise when you turn on alot of accessories (headlights, AC, stereo, etc)... and is really loud?

 

im not sure what in the transmission would squeal. u may have a bearing going in the distributor, alternator or water pump.

 

take it to the dealer.
