When the engine is cold, check for serpentine belt condition and tension with a flashlight and your hand by pushing on the belt at about the halfway mark between pulleys. There should be 1/2 inch or less play in the belt. Also check for cracking along the inside surface ribs of all belts. There should be 3 total belts if you have air conditioning. Any cracking along the belt ribs and the belts should be replaced and properly tensioned. If the belts look ok so far, have a helper start the vehicle while you watch the pulleys with a flashlight. Any signs of a pulley that is not rotating with the engine is a sign of the component attached to the pulley begining to seize. Whether this is a power-steering pump, A/C compressor or other pulley driven item, it should be inspected or possibly replaced by a qualified individual.

It sounds like you have a belt that slips when you take off. This will cause a high pitched squeal.

What causes a squeal in the engine on a 1999 Chevy Corvette to increase with acceleration?

I have a 99 and had a nasty squeal that would be intermittant upon acceleration, I changed the belts (upper and lower) and used Gatorbacks (belts by Goodyear), and the squeal is gone.. Don't know if this is the problem or not, but it will only cost you about 50 bucks and hour worth of your time to find out. Good luck!

You may need to tighten your belts. The power steering unit can be low on fluid.

Why would the serpentine belt on a 2001 Tahoe squeal?

Incorrect tension, or contamination. A bad bearing in the alternator, A/C compressor, etc will cause excessive stress on the belt, and it will squeal as is slides over the stiff parts. Also, serpentine belts are very sensitive to grease or oil. DO NOT use traditional V-belt dressing on a serpentine belt. The least it will do is squeal. At worst, it will pop off while the engine is running and you're under the hood looking at something. They have quite the bite when they let go.
