What is the Idler Pulley all about?

An idler pulley is responsible for guiding and maintaining tension with the drive belt. The drive belt (also called the serpentine belt) connects the engine to various components of the vehicle (such as the air conditioning, power steering, and alternator). Power is transferred from the engine to these systems via the drive belt. The belt is held in place by the idler pulley, which keeps the tension on the drive belt and guides it.

Keep in mind:

When an idler pulley is replaced, it’s a good idea to replace the drive belt as well.

How it's done:

Inspect engine for noises
Inspect the drive belts
Spin the pulley
Replace the pulleys if found bad
Check for proper operations of the belt

Our recommendation:

Any time that drive belt maintenance is performed on your vehicle, the idler pulley should be examined. Idler pulleys usually wear out with time, so it is a safe precautionary procedure to have your idler pulley replaced during any drive belt servicing.

What common symptoms indicate you may need to replace the Idler Pulley?

Noises from the engine
Warning lights are on
Loss of power steering
Car is overheating

How important is this service?

The idler pulley is responsible for keeping your drive belt aligned, and for maintaining the tension in the drive belt. The drive belt is used to transfer power from the engine to the alternator, power steering, and air conditioning, among other systems. If the driver pulley starts to degrade, the drive belt will be less efficient, and your vehicle will be liable to overheat or run poorly. If the idler pulley fully breaks, the drive belt will no longer work at all, and your car won’t run.

Mercedes-Benz 300E L6-3.2L - Battery - San Francisco, California

Was given a "fixed price" for two services, one was completed but the other was not because the price for egr valve jumped significantly. In conversations with company reps I was not satisfied with their explanation of "fixed price" being only in regards to service charge as the website does not state that, it stated that there will be "no surprises, fixed price for services requested..." I feel there was false advertising. the battery was installed as part two of the service before being informed of the price hike so I wound up paying for that and not getting the main service completed. had the higher price been given initially I would not have booked the service at all.

Although I had some difficulty reaching him at first, Alaa was communicative and honest on the phone. Helped me with a pre-purchase inspection of a vehicle I was planning to buy site unseen dealing with an extremely rude dealership.
