Think of it as your engine’s safety belt. Belt failure can cause permanent damage to your vehicle’s engine.
Serpentine belts power the air conditioner, air pump, alternator, cooling fan, power steering pump, water pump and other accessories. Heat and mileage cause belts to become brittle, crack, stretch out and break, causing your vehicle to stop. A worn or frayed serpentine belt is a hazard and will cause your vehicle to shut off and not operate. Serpentine belts should be replaced before you become stranded on the side of the road.
Potential problem? Simple solution.
While getting your oil changed, trained technicians check your serpentine belt and can replace it at recommended intervals (for most cars, that’s 40,000-50,000 miles) in a matter of minutes. So ask your service technician about your serpentine belt, and experience the feeling of driving as though you didn’t have a care in the world.
Oil ‘N’ Go recommends changing belts when there are four cracks per inch, a single crack is more than half the depth of belt, or every 40,000-50,000 miles.
