VIDEO: It Is Not Just The Belt That Wears Out
At 100,000 miles it is not just the belt that is worn, it’s the entire drive belt system. Failing to inspect and service the tensioner, pulleys and all the components the belt touches can cause premature failure of the new belt. Sponsored by Litens.
Engineering Better Belt Systems
When a piston accelerates downward after the ignition of the fuel and air, the crankshaft speeds up and then slows down as it reaches the bottom of the stroke.
Advanced Belt Noise Diagnostics
One of the noisiest components under the hood of a vehicle can be the belt and the drive components. Noise is not the fault of the belt, but the result of how the power comes from the crankshaft and the components attached to the belt.
10 Tips For Serpentine Belt System Inspection And Service
The serpentine belt is part of a system and is not the only component susceptible to wear. The tensioner, idler pulley and, on some vehicles, the decoupler pulley all wear over time and need periodic inspection and replacement. If you are replacing just the belt without looking at the other components, you could be sending a new belt to a premature death.
Top 10 Timing Belt Tips
Inspection is the most critical first step that must be performed before the first bolt is removed from the timing belt cover. The inspection needs to include looking for the usual leaks and inspecting items like the oil, motor mounts and accessory drive belt components. You should also scan the vehicle for both active and historical codes.
Automotive Belts, While Lasting Longer Than Ever, Still Wear Out Over Time
The typical replacement interval for serpentine belts and flat belts today is around 90,000 miles – which for many vehicles means only once every seven to nine years! That’s a lot of miles between belt changes.

Inspect The Belt Before The Replacement Interval
If you have looked at some maintenance schedules on late-model cars and trucks, you may notice that there have been some changes to the interval schedule for drive belts. Some manufacturers like GM are shifting to an inspection of the drive belt, instead of specifying a set replacement interval. While some manufacturers like Chrysler are recommending a 120,000-mile replacement interval in the owner’s manual.
Locking Down The Engine For Timing Belt Replacement
The relationship between the cam and crank is a critical one. You might say they are heavily dependent on each other for their survival because any slip-up and their union ends in catastrophe. Locking down engines for timing service is a necessity anytime you remove the crank or cam pulley or have to replace the belt itself.
Subaru Stretch Belt Inspection & Replacement
If you see a belt on a late-model Subaru that does not have an automatic tensioner and runs between only two or three components, it’s probably a stretch belt. These types of belts typically are used to turn the A/C compressor on the 2.5L four-cylinder engine in 2008 and later models.
