Nissan Pathfinder Elusive Chirping!
I've been having a problem with my 98 Pathfinder for about a year now, and no mechanic has really figured out what is causing it. I've got a VERY loud chirping noise coming from my engine. Sometimes it will come and go, other times it will be consistent for weeks. It gets louder when I accelerate and a little louder when I turn on the AC. Here's what has been concluded so far:
1) It's not the belts - They were changed two years ago
2) Mechanics have tried spraying the pulleys with some WD-40 but if anything, it got louder (They also replaced two of these pulleys...)
3) In warmer weather, after driving for more then 30 minutes or so, the chirp will stop completely (when idling).
4) Doubt this is related but maybe it's relevant - When listening to AM radio only, pressing the gas pedal causes a loud static to interfere with the signal...The more I press the pedal, the louder it gets
I've seen 3 other Pathfinders with the same exact problem. Perhaps it's something common? Any ideas or starting points?
