Why Idlers And Tensioners Also Require Replacement When Changing S Timing Belt?
Timing belts have a limited service life. That’s why belts should always be replaced at the vehicle manufacturer’s suggested mileage period. But a belt alter alone may not be sufficient because the majority of belt failures are in fact caused by faulty belt tensioners and idlers. These failures can result in major engine spoil and costly repairs. Consequently, the new timing belt you’ve just installed may fail after a few thousand miles if the tensioner or idler is worn or loose.The peculiar idlers and/or pulleys that are used on many OHC engines to maintain belt tension also have a limited service life — which in some cases may be less than that of the belt! Their lifespan depends on their location, operating temperature, load, engine rpm and other environmental factors. Most tensioner and idlers have a design life of around 2,000 hours, which may be the equivalent of 40,000 to 60,000 or more miles of service depending on how the vehicle is driven. Unless these apparatus are also repl
