Drive Belt Idler Pulley Replacement

What is a drive belt idler pulley?

The term “Drive Belt” is a generic term used to describe a set of belts that are used to run engine accessories such as the alternator or power steering pump. These belts must be routed in a manner that prevents contact with other belts or components, necessitating the use of an idler pulley. This helps locate the belt, while allowing it to spin freely.

How does the drive belt idler pulley work?

While the engine is running, the crankshaft pulley is constantly spinning. This provides drive to other mechanisms by means of a belt. The belt will be tightly wrapped around the crankshaft pulley and the accessory pulley, so the belt is unable to slip. Manufacturers use idler pulleys to route the belt around various engine accessories.

What is a drive belt idler pulley?

How does the drive belt idler pulley work?

What are the symptoms related to a bad drive belt idler pulley?

If the drive belt idler pulley fails, there will be a very audible chirping noise from the front of the engine. This is because the idler pulley bearing is no longer smooth, and rotating causes metal to grind at high speeds. If it is not changed immediately, there is a chance it will become dislodged, or allow the drive belt to slip off. If the belt falls off, the accessory that it drives will no longer function. For instance, if the alternator belt idler pulley fails, the alternator may stop functioning. Also if the pulley begins to wobble, allowing slack in the belt, it will make an extremely loud squeaking or screeching noise, especially on cold starts. This is the belt slipping on the crankshaft pulley, and will require belt replacement once the idler pulley is replaced.

Can I drive with a drive belt idler pulley problem?

Depending on which belt breaks, driving the car may be hazardous or impossible. The power steering belt and air conditioning compressor belt will not disable the vehicle, but the vehicle may be unpleasant to drive. If the engine cooling fan belt breaks the engine may overheat, causing further damage. If the alternator belt is broken or missing the vehicle will need to be towed, as battery power will only last a few short minutes.

How often do drive belt idler pulleys need to be replaced?

Idler pulleys tend to last quite some time. However, driving style and operating environment may affect part longevity. The majority of vehicles will surpass 100,000 miles before idler pulley replacement is needed.

How are drive belt idler pulley issues diagnosed?

If the pulley is making sufficient noise to be suspected, it will be physically inspected to verify the diagnosis. The drive belt will be relieved of tension, and the pulley turned by hand to feel for vibration, resistance, grinding, or looseness. If any of those symptoms are noted, it will be replaced.

Care must be taken to properly diagnose a noise from the drive belt area. In some cases, it can be quite difficult to determine which component is causing the abnormal noise.

How is a drive belt idler pulley replaced?

When replacing a drive belt idler pulley, the remaining parts of the pulley system will be inspected to ensure they are free from defects that will lead to damage of the new belt or idler pulley. If there are no defects, the belt tension will be released, and tightened once the new idler pulley and belt are in place. Proper belt tension is mandatory to prevent belt failure.

The drive belt(s) should the thoroughly inspected and replaced as necessary when servicing a drive belt tensioner or idler pulley.

RepairPal Recommendations for drive belt idler pulley issues

When one drive belt component fails, it is typical to notice the others in need of replacement as well. The belts should all be removed and inspected, as cracking or fraying may be hard to detect while on the vehicle. While the belts are removed, the idler pulleys and belt tensioners should be inspected and replaced if faulty. If the drive belt is broken or missing, all pulleys and components for that belt should be inspected for proper alignment and functionality.
