The average lifespan of a belt tensioner can vary greatly depending on the make and model of your vehicle, as well as the type of driving you do.
If your belt tensioner fails, it can cause extensive damage to your engine. Not only will this cost you time and money to repair, but it can also be dangerous.
So How Long Does A Belt Tensioner Last? In this post, we’ll help you learn more information about belt tensioner, let’s find out together!
The belt tensioner keeps the engine components moving by working with the drive belt, also known as the serpentine belt. The rubber loop keeps the air conditioning compressor, water pump, alternator, and power steering pump pulleys in motion while the engine is operating. With the aid of the belt tensioner, this component transmits power from the engine to these systems.
The belt tensioner is generally a pulley that’s attached to a bracket designed specifically for the vehicle. By adding tension to the pulleys, this part ensures that all engine components are running as intended.
The belt tensioner is under pressure from a spring, which allows it to adjust as needed. With any type of belt, having the correct amount of pressure is key to keeping your engine running properly. Over time, though, the belt tensioner will lose its ability to apply tension to the serpentine belt. Sometimes this is because of repeated use weakening or freezing up the mechanism. Or sometimes the pulley itself warps, cracks, or starts making noise (usually a squeak) from throwing a bearing.
You should expect to replace your belt tensioner every 40,000 to 60,000 miles. Some vehicles have a maintenance-free belt tensioner that contains a sealed bearing that doesn’t require lubrication. For these models, all you need to do is keep an eye out for any signs that the tensioner is going bad.
If your belt tensioner is going bad, you may notice one or more of the following symptoms:
The cost of belt tensioners varies widely, but the average is around $200. The price of components and labor may range from $140 to nearly $400, depending on the make and model of your car.
Belt or tensioner squealing. When the engine is running, the tensioner should be silent. If the pulley is broken, replace both the tensioner and assembly.
Bad belt tensioners leads to less power for accessories, which is dangerous. Eventually, the bad tensioner will cause the belt to slip, generate noise, and create heat along the accessory pulleys – all of which are unsafe.
Serpentine belt replacement is now easier than ever before because of modern automatic drive belt tensioners. With these, there’s no need to loosen bolts or position pry components back into place for retensioning. All you have to do is rotate the tensioner, remove the oldbelt and put a new one on.
If you think your tensioner or idler is failing, look for the following symptoms: Excessive tensioner movement – Worn-out coil springs can also loosen the grip of drive belt tensioners on the drive belt, causing vibrations and rattling.
If the tensioner breaks, the serpentine belt falls off and snaps. This also causes the alternator, power steering pump, and AC compressor to seize. Since there is no longer a belt rotating the pulley, the battery light Turns on and makes steering much harder. The AC will also stop cooling at this point.
When a car’s timing belt begins to deteriorate, it makes a ticking sound in front of the vehicle. If the belt fails, it will make a whining noise when attempting to start the engine. There is no compression in the engine, making an audible whine.
If your serpentine belt fails, it can cause a domino effect of car failures, the most severe being that your engine will stall. Not to mention, this is dangerous and wildly inconvenient.
The lifespan of a belt tensioner can vary greatly depending on the make and model. However, by following the guidelines provided in this article, you can help to extend the life of your belt tensioner and keep your engine running smoothly.
