Land Rovers are popular for their durability and ease of driving over rough road surfaces. However, one problem that is common to Land Rovers is the idler pulley failure. The idler pulley is an important car component that supports the drive belt system, giving it enough tension to keep car parts like the AC, alternator, and water pump running.
Idler pulley failures are common in Land Rovers, so you need to understand why they happen and what to do to prevent such failures.
Leading Causes of Idler Pulley Failure in a Land Rover
If a Land Rover’s Idler Pulley fails at any point, it could be due to any of these reasons.
1. Poor Quality Pulley
As is common knowledge, anything that has a manufacturing fault will have a short lifespan and can fail easily. Hence, the idler pulley could cause problems if any of its parts are made with materials that are as strong or as durable as required by Land Rover.
2. Misalignment
Aside from bad quality, another reason why the idler pulley in any vehicle could fail is if the pulley is not installed properly, causing a misalignment. The pulley needs to be aligned right with other parts of the belt system to effectively perform its function. If this is not so, the pulley is under more stress than necessary, which could cause it to fail.
3. Contamination
The presence of contaminants in any part of a car system is a great risk, and this can be the case for a failing idler pulley. The idler pulley needs to be in contact with some engine parts to function adequately. However, if dirt or debris get stuck around the pulley areas, they could cause more wear and eventually lead to a failing system.
4. Overloading
Because Land Rovers are large SUVs with the ability to handle extreme road conditions, many Land Rover owners overdo it by overloading the vehicle. While the Land Rover can effectively navigate difficult roads, the idler pulley could get damaged in the process. Hence, if you constantly overload your Land Rover, you are putting it at risk of idler pulley failure.
Warning Signs to Watch For
The signs you will notice in your Land Rover if the idler pulley fails are:
- Strange squeaking, grinding, or rattling sounds from the engine.
- Fault in car components like the Air condition system, water pump, or alternator.
- Engine overheating.
- Loose serpentine belt.
- Visible signs of wear and damage on the pulley.
- “Check engine” light comes on.
