The shop releases the belt tensioner, routes a new belt around the pulleys, and checks the tensioner and idler pulleys for wear and noise.
Signs you need it
- Squealing on cold starts or when turning
- Cracks across the ribs of the belt
- Belt looks glazed or frayed
- Battery light or heavy steering if the belt slips
What changes the price
- Some engines need a motor mount or splash shield removed
- A worn tensioner or idler pulley is often replaced at the same time
- Belts themselves are inexpensive
Shop or do it yourself?
Usually easy with a long breaker bar and a photo of the routing.
Questions drivers ask
How much does serpentine belt replacement cost?
At a typical shop, labor runs $50 to $160 (about 24 min to 1 hr of work), and the serpentine belt costs about $25 to $75. That puts most jobs between $75 and $235 total. With SwaxFix you can buy the part yourself and have local shops bid on the labor only.
How long does a serpentine belt last?
Typically 60,000 to 100,000 miles. Replace it sooner if it is cracked or noisy.
What happens if the belt breaks?
The alternator, power steering and often the water pump stop. The engine can overheat quickly.
Should I replace the tensioner too?
If it is noisy, wobbly or past about 100,000 miles, doing it now saves a second labor charge.
