The Purpose of A Serpentine Belt
Engines rely on the serpentine belt to deliver energy to various components to power them, such as the water pump, alternator, power steering pump, and air conditioning compressor. Before being installed, the serpentine belt is a single continuous circular loop. When installed, it snakes around the crankshaft pulley where it accepts engine power and delivers it into the accessories that need the power to operate.
When Does my Serpentine Belt Need to Be Replaced?
Replacement intervals will vary according to the Ford model and its driving conditions. The average serpentine belt will need to be replaced at 100,000 miles if it does not fail an inspection before. Because a failed serpentine belt can cause major damage to the engine if the water pump is offline, we recommend routine inspections and replacement service if your belt shows any signs of integrity loss or risk.
Symptoms of a Faulty Serpentine Belt
If you notice any of the symptoms of a serpentine belt losing integrity, it has poor reliability and an increased risk of failure while driving. We recommend getting the serpentine belt replaced promptly if you detect any of the three telltale symptoms of a faulty serpentine belt:
- Squealing sound at the front of the vehicle, especially when starting the engine
- Belt has lost integrity due to excessive cracking, rib separation, or fraying.
- Power steering, air conditioning, or alternator not working correctlyÂ
