Several timing belts supplied for the automotive aftermarket marketplace will not adhere to OE specs, carry “belt only” warranties and may perhaps leave services dealers at risk for high-priced engine repairs, based on the Gates Corporation.

A timing belt failure can be a critical problem. Not merely does it strand the motorist, however it also can cause critical engine injury. The high compression “interference,” OHC automobile engines of these days are more compact and lighter than their predecessors, with really near tolerances in between the pistons and the valves. Timing belts synchronize the action from the pistons and valves in the combustion chamber, protecting against them from occupying the same area simultaneously. In the event the timing belt breaks, synchronization is lost, valves and pistons collide, and major engine harm benefits.

Repair outlets and do-it-yourselfers who set up a timing belt which has a “belt only” guarantee could be stuck for virtually any associated engine repairs when the belt fails.

The situation has surfaced thanks to the role of some “repackagers” while in the automotive aftermarket marketplace. These businesses acquire up 1000’s of timing belts from several producers, “rebox” them and promote them to parts suppliers. A number of these parts provided on the automotive aftermarket may possibly not meet the exacting specifications of today’s modern-day engines. They might break or put on out faster than high-quality, OEM-approved parts. Most significantly, these price range belts tend not to cover engine repairs or labor if there exists a dilemma.

Adjustments in belt resources in recent years have led on the creation of prolonged daily life belts manufactured of the particular high-temperature grade composite known as “highly-saturated nitrile” (HSN), or EPDM. An HSN or EPDM belt appears no diverse than a chloroprene belt, but considerably outperforms in the high temperature engine compartments of present day cars. Regrettably, tests present that some timing belts supplied by some “repackagers” are produced of chloroprene when HSN or EPDM is required in the OE level. Chloroprene belts when misapplied can result in premature engine failure and high priced repairs

When you are buying a replacement timing belt, request the seller what kind of guarantee comes with the belt and what precisely it covers. If it doesn’t include things like a comprehensive guarantee, do not get it. The threat is not really worth it. Spend several dollars much more to get a high-quality belt made of HSN or EDPM that meets OEM specifications and it is backed by a parts and labor warranty.
