Rev On start up causing problems

[park233]

So.. If i start my car and rev a little I get a swelling/screech sound, like a belt or something..It only happend like 1 min and before after starting..Its fine after a min or two of running.. Just wondering if its something to worry about and, or what its caused but specifically.

replace your belts

Could be a pulley

That is definitely something to worry about. Pull the belts and check each rotating part for rough bearings. While the belts are off and the engine is cold, fire the engine and see if the noise is still present. The noise being present then indicates a problem with timing belt and/or tensioner. If The TB is okay and the rotating parts are okay, install new belts and properly tension them.
