Failure Symptoms
  • Coolant loss without visible external leaks
  • White smoke from the exhaust after warm-up
  • Milky or emulsified engine oil
  • Overheating at low speeds or under load
  • Rough idle, misfiring, or loss of power
  • Pressurized coolant hoses
  • No hot air from the heater
Critical Installation Notes

⚠️ IMPORTANT: Always use new cylinder head bolts — never reuse old head bolts. The cylinder head bolt tightening procedure requires 100 N·m for the 18 main M12 bolts, and 24 N·m for the 2 smaller M8 bolts, in the specified sequence.

The cylinder head warpage limit is 0.05 mm — resurface or replace if exceeded. Always replace the cylinder head gasket with a new unit.
