Why the Timing Belt is Integral to the Engine
A standard internal combustion engine has around 200 parts. Many of these require regular inspecting, servicing, and replacing. One pertinent component is the timing belt. This part manages the function of the camshaft, which opens and closes the intake and exhaust valves in precise correlation to the crankshaft; the crankshaft converts the pistons’ vertical movement into horizontal rotational movement. It uses teeth to turn the camshaft to ensure proper combustion. Most timing belts are made of rubber, making them quieter and more efficient than timing chains, though some can be made of polyurethane or neoprene. Because they are a rubber material, timing belts will last 60,000 to 100,000 miles, or seven to 10 years, before needing replacement. It’s essential to heed the recommended replacement interval outlined in your owner’s manual, as it can vary from model to model. We’re here for you if something goes awry with your timing belt.
