I was leaving this morning for work it was around 35 out and I don't have a plug for my truck. Got it started and let it sit for about 10 minutes or so and left. Went a mile or so kept it around 40 and under 2000 Rpms when I slowed down for some people and then sped up I heard a squeak /squeal for about 10 seconds. What could it be it went away and haven't heard it since then
I'll put it this way: It was belt slipping over a pulley. But it could be cause by a weak tensioner, pulley bearing going bad, or a belt.
Mine wouldn't squeak all the time, but usually did when it was cold or humid. Until it does it a lot or you can pinpoint it, I wouldn't worry.
