I have this annoying problem with my escalade. I bought one for around 40k and the engine squeaks like crazy! When at idle when you turn it on, it makes a squeaky noise, sounds like it's the belt. When I rev it at idel it gets more intense.... Occasionally driving down the highway on colder days or any day under 65 degrees you can hear the belt or something squeal at high speed and them sometimes it's warm and it does do it at all.
Is it just the belt? Any Ideas?
