'94 Grand Cherokee chirping sound coming from engine?
I have a 1994 Grand Cherokee Laredo 5.2L V8 AT.
When the engine is cold, or has been sitting for a few hours (unless under extreme high temperatures), the engine area produces a "chirping sound." After the engine has been running (10-12 miles), the chirp quiets down.
The sound is loudest when I accelerate.
I've had a new water pump installed, as well as the idling/tension pulley and new serpertine belt.
The serpentine belt is NAPA, not a factory Jeep belt. I've had mechanics say putting a factory belt on it might help. Does anyone think, in addition to installing a factory belt, that the problem could be a bad bearing in the alternator?
The voltage gauge in the instrument panel cluster hovers around 11-13, which is a little lower than that in my 1994 Cherokee SE 4.0L.
Thanks for any input. The chirping drives me nuts!
