Overheating problems Cavalier

My Cavalier Overheats Owners of GM 2.4 engines may encounter overheating problems that drive them crazy.

Water pump leaks on GM

Leaking water pump on GM Water pumps are built with a hole directly below the seal assembly. The purpose of the hole is too allow the seal to breathe as it expands and contracts from heat. During those periods of expansion and contraction, a small amount of coolant may seep past the seal and drip out the hole. To most of us, coolant coming out of the “weep” hole is the sign of a pump about to give up the ghost. In this case however, it’s considered normal. Changing the … Read More

Clunk noise in steering

Fix clunk noise in steering on GM vehicles If you have a Clunk noise in steering in a 1997-2005 GM it’s caused by a “stick/slip” condition in the intermediate steering shaft. This is the portion of the shaft that goes from the steering column down to the rack. Because it has a flexible joint in it, the shaft is made to expand and contract. You guessed it, the grease they used causes it to bind. The new grease is part of a kit #26098237. You remove the intermediate shaft and inject … Read More

Droning noise from car on Cavalier and Sunfire

Fix droning noise from car on Cavalier and Sunfire Cavalier or Pontiac sunfire Got one of these with the 2.2L (Vin4) engine?  The droning noise happens most at high outside temps with the engine idling and the A/C on.  The problem is the accessory drive belt developing a resonance in the span between the alternator and A/C compressor.  The fix is to install a newer design belt GM #12575450.  The new belt is made out of a newer rubber compound that eliminates the noise. © 2012 Rick Muscoplat Save
