Serpentine Belts

The serpentine belt is a part of your car’s engine that’s crucial to many components. It’s also known as the drive belt. It provides power to the AC, alternator, power steering pump, and sometimes the water pump. Belt failures are usually caused by a damaged belt tensioner, misalignment, incorrect tension, fluid leaks, or wear.

How Long Do Subaru Serpentine Belts Last?

To know detailed information about the lifespan of your Subaru’s belts, refer to your owner’s manual. In general, serpentine belts last between 50,000 to 100,000 miles. Where your vehicle might fall within this range depends on many factors. These factors include the model and trim of your vehicle, as well as exposure to heat. Regardless of condition, experts suggest replacing the belt at 90,000 miles.

What are the Signs of a Failing Serpentine Belt?

Here are signs the serpentine belt is starting to fail:

  • Power steering isn’t working.
  • Air-conditioning isn’t working.
  • Check engine light flashes.
  • You hear a squealing or squeaking sound from your car’s hood.
  • You smell burnt rubber.
  • The engine overheats.
  • When checking the serpentine belt, you see cracks or glazing on the sides.
