Why would a 1994 Geo Prism belts squeal when the car starts?

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.
