When my engine is cold it squeals a little when I first start it. Then it doesn't do it again. I have taken it in for service repeatedly and they can't find anything . Any Ideas, before I take it and leave it overnight?

 

loose belt?

 

They have checked everything a couple of times. He did mention maybe a pulley but I need to leave it overnight which is really hard for me since I live in a rural community and drive every day

 

Go to O'Reilly Auto Parts...

Buy some belt conditioner, it'll be on the maintenance chemicals wall...

Spray some on your belt following the directions on the can...

tada! That should fix it pretty good.
