SOURCE: High Pitch whine during acceleration

well it could be a few things but most likely you belt is sliping. That is very common and happens to all cars over the years if the belt is not changed. You should check it out. The belt could be bad but it could also be a bad pully. If you dont know what these parts are look them up on google. its very simple

SOURCE: high pitch whistling noise in engine compartment of 2005 envoy

There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.

SOURCE: van brakes squeal/whistle even when stopped

Sounds to me like a dry, loose or worn serpentine belt. With the motor idling, lightly spray the serpentine belt as it's spinning with WD-40 or other oil based lubricant (Don't spray near the alternator). If this doesn't work, turn the mortor off and check the tension and for cracks or worn spots. The brakes will not squeal when you are completely still.

Makes high pitch whistle


Do you have the brakes taken apart once a year,
on all your vehicles, for rust removal,inspection,
needed work & lubing,that is required
Have to flush brake fluid every 2 years, if you
don't want moisture in the system ruining it
Don't know what the noise is,work on the
brakes & then get back to the noise, if it's
still there

I have a 2003 Jeep Wrangler that has a high pitch SQUEALING sound when I release the accelerator. Any ideas what's causing it or how to fix it?.


I know i have the same problem, and i also noticed than when i open the Hood the whistle just stops, so i figure out it must be some air cycling in or out osmewhere, I found out my air intake connected to throttle body was misplaced a weird gap was left open allowing air to whistle. u might wanna check there

When i give my car gas a whistle comes from the engine. It's a high pitch continual sound. When i let off the gas the whistle stops. It sounds like it's coming from the top of the block.70k miles...


Sounds like a vacume leak, chk. for a cracked or broken vacume line or maybe one came off. Does it idle ruff? With it running open hood and listen for a low pitch whistle you may have to rev it up a little.
