Engine Weaknesses 5

!! Timing belt maintenance interval

!! Timing belt interference engine

The Alpha G4EK is an interference engine with a timing belt. If the belt fails without timely replacement, valves bend and the engine is an economic write-off.

Symptoms: Engine suddenly won't start; loud bang on failure; no compression afterwards.
