Installation & Maintenance Tips

Surface Flatness Check
– Maximum allowable warpage: ≤ 0.05 mm. Resurface if necessary.
Use New Head Gasket & Bolts
– Only install a multi-layer steel (MLS) head gasket.
– Cylinder head bolts are torque-to-yield (TTY); never reuse.
Recommended Torque Sequence
- Step 1: Tighten to 29 Nm
- Step 2: Tighten to 78 Nm
- Step 3: Loosen all bolts
- Step 4: Retighten to 49 Nm
- Step 5: Final torque with 90° + 90° turns
Cooling System Must Be Flushed
– Overheating is the most common cause of head damage. Replace thermostat, inspect radiator, and ensure water pump is functional.
Check for Cracks and Pressure Test
– Particularly in exhaust ports and water jackets.
Timing Belt Replacement Recommended
– Replace belt and tensioner when replacing head to avoid future failure.
