Reasons Behind Idler Pulley Failure in Your Land Rover
The Land Rover is a great vehicle for all your driving adventures. The brand is known to offer both luxurious style and durability to traverse rugged terrain. Whether you’re travelling on major highways or experiencing the fun of off-roading, Land Rovers are built for high performance, strength, endurance, and power. However, as with all vehicles, Land Rovers do experience issues from time to time. One of their more common issues is a failed idler pulley, which can become serious if the problem isn’t diagnosed and repaired as soon as possible.
This article will explain the basic function of the idler pulley and discuss symptoms you should look for when your Land Rover’s idler pulley is malfunctioning and what you can do to fix it.
What does the idler pulley do?
The idler pulley is a vital component in your vehicle’s ability to function properly and safely. As a part of your engine, the idler pulley is responsible for preventing slack in the engine drive belt. This belt transfers power to the alternator, water pump, AC compressor, and power steering pump. In doing so, this allows your engine to run smoothly and efficiently. Therefore, without the idler pulley, these four engine accessories won’t receive the power necessary to fulfill their individual roles. So, if the idler pulley fails, your vehicle’s engine will ultimately fail too.
What are the symptoms of a failed idler pulley?
Fortunately, when an idler pulley malfunctions or fails altogether, there are some clear and basic signs that you can look for to help you to easily diagnose the problem. Here are 5 of the most common symptoms:
Unusual noises are never a good sign when it comes to your vehicle. This is why it’s important to always be listening and paying attention to the sounds your Land Rover is making. If you hear a squealing or chirping noise coming from underneath your hood, you may have a bad idler pulley.
Because the idler pulley plays such a major role in the function of your engine, noticeable engine problems may be a result of a failed pulley. Since a bad idler pulley can damage your car’s drive belt, which is necessary for your engine to be able to regulate its temperature and to perform, overheating and stalling are two signs that your idler pulley might need to be replaced.
One way to test if your Land Rover has a frozen pulley is, while your car’s engine is turned off, carefully remove the drive belt and try to spin the pulley. If you can’t spin it easily, then this is indicative of bad ball bearings, and both the bearings and the pulley will need to be replaced.
Wear and tear
It’s inevitable that your vehicle will experience some wear and tear as the years go by. Since Land Rovers are often used to travel across rough terrain, their parts can tend to wear down faster than in vehicles that are only used for driving on the road. You should regularly check the idler pulley for signs of wear, such as scoring marks.
Drive belt slack
Since the idler pulley is the component tasked with maintaining the tension in the engine drive belt, significant slack in the belt is a sign that the idler pulley has stretched and is unable to fulfill its primary role in your Land Rover.
What is the solution?
Because the idler pulley is vital to your engine’s ability to function, it’s important to quickly diagnose the issue and have it repaired as soon as possible if you suspect that the idler pulley is failing. If left unfixed, a failed idler pulley will wreak havoc on your engine and can cause permanent damage to your Land Rover.
