For the life of me I can’t quite narrow down this squeaking sound. I little while back, I thought it was the belt and/or tensioner. Replaced belt with a spare used one I carry and a new tensioner. Also ordered a new Goodyear belt.
Checked water pump, A/C compressor, power steering pump, alternator and idler pulleys for play, no play noticed and spun smoothly with no odd or grinding noises. Power steering pulley did have some noise if you rotated it back and forth quickly in a rotational direction, but didn’t continue if you just spin it in one direction. Also checked all these with a mechanics stethoscope where I safely could while the engine was running and didn’t hear anything unusual.
Ran the engine with no belt at all and no squeaks or any other noises. .
New Goodyear belt came in so I put it on and no squeak for a few days. Then it started up again.
I ran it with the a/c on to see if the compressor kicking on and off made a difference and it seems like it’s slightly different but I don’t know if that means anything or not. Also replaced the idler pulley with a new spare, still squeaking.
Any ideas where to go next without just throwing parts at it?
Power steering pulley from earlier this month.
