As soon as I start my car it starts a really loud squealing
belt sqeals when starting in extremely cold times. Belt has broken twice when below zero temperature. replaced adjuster and it has helped some but broken another time after that as well. temperature was below zero when it broke.
Oil leak suspected in wearing down / loosing alternator belt, eventually breaking altogether.
A couple of times I have had to replace the belt.
Squealing after about the first 100 yards. Not fixed yet.
Tightened alternator play
has not been fixed yet
My car usually squeals during a cold startup. I just replaced the belts and the squealing persists. From reading this, I am now suspecting that its the timing belt.
