Serpentine Belt Replacement Cost - HEIYI

A serpentine belt drives vital engine components such as the water pump, alternator, power-steering pump and air-conditioning compressor. The belt, named serpentine because it winds through the front of the engine in a snake-like manner, replaces the system of multiple belts that was common on older vehicles.

Typical costs:

Hiring a mechanic to replace a serpentine belt typically costs about $60-$200 or more. This includes $25-$75 for the belt plus half an hour to an hour of labor, at $75-$120 per hour. 

The job could even take longer on some vehicles, if the belt is difficult to access or install quickly. RepairPal allows drivers to get an online estimate based on their location and the year, make and model of the car.

Purchased separately, a serpentine belt typically costs $10-$75. For example.

What should be included:

If a serpentine belt breaks, certain systems in the car may shut down, so experts recommend that a belt be replaced early, especially if it shows signs of cracking or wear. If possible, it is best to get an estimate before approving any work. However, if the belt has failed, the car may not run.

Replacing a serpentine belt can be done either by a skilled do-it-yourselfer or a professional repair technician. Popular Mechanics explains how to replace a serpentine belt.

Additional costs:

A failed belt could require the vehicle to be towed, which can cost more than $200, depending on the distance.

A technician may find other repairs he or she would like to perform. These repairs could include any damaged or worn parts a technician may find or any factory-recommended maintenance an owner has overlooked.

If any pulleys, such as the idler pulley, need to be replaced, that could cost an extra $13-$33 for the part.

Discounts:

Some repair shops might offer a discount on repairs for regular customers, usually about 10%. For example, some shops give discounts to AAA members.
