What does interference mean?
In an interference engine, the valves and pistons can collide if the timing belt breaks. This can cause serious damage to the engine, including bent valves, broken pistons, and even damage to the cylinder head.
Why is it important to know this?
It's crucial to replace the timing belt on an interference engine at the recommended intervals. This helps prevent catastrophic engine failure.
How to find out if your specific 2002 Lancer is an interference engine:
* Check your owner's manual: The manual should specify whether your engine is interference or non-interference.
* Look up your engine code: The 4G63 engine is an interference engine.
* Consult a mechanic: A mechanic can tell you for sure if your engine is interference.
Remember, even if your engine is non-interference, it's still important to replace the timing belt on schedule. However, the consequences of a broken timing belt are less severe in a non-interference engine.
