How Often Should You Replace Your Tensioners, Idlers and Dampers?
Tensioners, idlers and dampers are three incredibly important engine components. Without them, your car wouldn’t be able to run. But how do you know when to replace these vital car parts? What are the risks if you don’t replace them?
In this blog post, we’ll explain how often you should replace your tensioners, idlers and dampers.
When Should You Replace Tensioners?
Tensioners add pressure from an adjustable pivot point or spring mechanism to keep your serpentine belt taut as it circulates around the engine.
There is no recommended timeframe in which to replace your tensioner, especially as the belt itself usually needs replacing before the tensioner does. However, you should inspect your tensioner each time you service your car to monitor its condition and replace it if necessary.
When Should You Replace Idlers?
Idlers guide the drive belt around its cycle, creating the tension needed to keep it on track. Idler pulleys are designed to last beyond the lifespan of the car, so it’s one of the car parts that you’re less likely to need to replace.
However, the plastic or metal (depending on the idler) does wear away as the part is in constant use. A failing idler can bring an engine to a grinding halt, so it’s important to self-service idlers despite their reputation as long-lasting engine components.
When Should You Replace Dampers?
Dampers – shock absorbers – are mechanical or hydraulic devices that absorb and dissipate shock impulses. These tiny devices are integral to your car’s suspension system, but how often should you replace them?
Some manufacturers recommend replacing your dampers at around the 50,000-mile mark or after four to five years. However, if you frequently drive over potholes, bumpy roads or sharp cracks, your dampers will wear faster. Therefore, it’s not always ideal to measure damper length via mileage or years. Instead, use these as guides as you inspect your dampers for signs of damage.
