Chirping sound 2003 Alero makes a very irritating chirping sound. I know it's coming from one of the belts. The dealership I bought it at replaced the belt and I've used conditioner. That helped but it's still there and very annoying. Could it be the pulley the belt is on? As far as I know and can tell, it does not affect the actual driving of the car - it runs great and I have had no problems with it!

check the entire engine freeze plugs hoses radiator . check engine oil .if look like milk shake you got a blown head gasket. if it dont burn oil dont smoke . fix the leak . if it got 150000 or more . cost to much to fix buy another engine.

it depends what you want to do. you can take the compressor right out and run a smaller belt.,if it will allow that,or replace it if you want air conditioning.

Brute force - you have to pry up the tensioner pulley. The way we did it was put the belt over the alternator and A/C compressor, and get it back in place around the main bearing pulley. Then we took a bar and forced up the tensioner and slid the belt over the main bearing pulley. Voila . . .

its not a hard job to do you need a wrench to rotate the tensioner bolt.a socket and breaker bar wont fit.

seems like the pressure line to the rack&pinion is plugged.open the line at the rack see if fluid flows if not replace line if fluid flows then replace the rack.
