Ok, so I recently switched out my serpentine belt (82K miles) because it was squealing regularly. A loud squeal when accelerating could be that you have a loose or worn fan belt. 3 Reasons why my car makes a squealing noise when I drive Squeal While You Accelerate (Belts) you're probably going to need to look at the timing belt as. I don't think it is the stepper motor because there is no popping while driving in circles. But also, not always, it's just when I'm accelerating. Without proper tension a belt will slip, the sidewalls will wear smooth, and the belt will eventually harden through "heat-ageing", a process referred to as glazing. my car had a bad head gasket, and my mechanic helped me do the head gasket, but after he did it, it is now squealing when i accelerate. Well now it sounds like a moped going down the road. Heavy Exhaust Fumes - If you notice more smoke and fumes than normal coming from the exhaust, this could be another indication that your timing belt is overdue for a replacement. When I accelerate at just about any speed, 25mph, 50mph, I get a strange noise that sounds like bearings that aren't properly lubricated, raspy, high pitched and metallic. New timing belt. All was well. Improper Installation: When installed, the belt must be tensioned appropriately and then re-tensioned again after a few minutes of running the engine. Its not bad,not loud, just mildly annoying to me. I have a 2007 MK3 Ford Galaxy 1. The 2000 Ford Focus has 4 problems reported for high pitched whining noise while accelerating.
