1. Understanding Timing Belts and Timing Chains
What are timing belts and timing chains, and why are they important?
Timing belts and timing chains synchronize the rotation of the crankshaft and camshaft, ensuring that the engine’s valves open and close at the correct times. This synchronization is crucial for the engine to run smoothly and efficiently. According to a study by the National Institute for Automotive Service Excellence (ASE), proper timing is essential for optimal engine performance and longevity.
1.1. Timing Belt
What is a timing belt?
A timing belt is a rubber belt with teeth that meshes with pulleys on the crankshaft and camshaft. Timing belts are quieter than chains but require replacement at specified intervals to prevent breakage, which can cause significant engine damage. The replacement interval typically ranges from 60,000 to 100,000 miles, depending on the vehicle and manufacturer’s recommendations.
