2003 Chevy Malibu 6 cyl Front Wheel Drive Automatic 136000 miles
I'm getting a clicking/popping noise in the engine compartment. It sounds like it's coming frm the exhaust manifold and has the sound of the expansion/contraction of metal. The heat shield covering the manifold is intact. I just installed a new catalytic converter, but it hasn't eliminated this noise.
It's not just when the engine is hot that the problem occurs. Upon immediately starting the vehicle when it is cold, the clicking/popping noise is apparent. It's not extremely loud, but the sound is audible if you are standing next to the engine. It's not constant, but intermittent. The sound continues as the vehicle is driven ( I notice it when I'm at a stoplight) and doesn't stop until some time after the vehicle is shut off.
The engine temperature gauge is normal. I was thinking that perhaps coolant wasn't completely circulating in the engine.
have the same problem?
