2005 Buick Park Avenue QuestionsThis is my elderly sister's car. There is a clicking sound under the hood and her mechanic cannot find the source. Replaced alternator and belt. Is there a sensor or bearing that would make that sound and not show up on a diagnostic check? (2 answers)
Can't be brakes because it happens while idling. She can't afford to have them guess. It really is a nice car.
I found 2 external torx under front pulley.Is that it?
It's not the gas cap. Could changing the Canister Purge Valve solve the problem? I reset the code about 4 times per tankful of gas.
