Pre-Installation Checks:
- Ensure the cylinder head and engine block surfaces are clean, dry, and free from any debris or old gasket material.
- Verify surface roughness: For MLS gaskets, the recommended roughness is 0.5 / 1.0 µm, with a maximum of 2.3 µm. For cast iron, 1.5 / 1.8 µm, with a maximum of 3.8 µm.
- Head Bolts: Head bolt replacement is highly recommended. Refer to HBS Ref.: 81036100 for compatible head bolts.
- Hydraulic Lifters: It is highly recommended to replace the hydraulic lifters. Refer to AJUSA Ref.: 85009000 for compatible lifters.
Gasket Placement and Torque Sequence:
Position the new cylinder head gasket carefully on the engine block, ensuring correct alignment with all bolt holes and passages.

It also includes references for recommended head bolts and hydraulic lifters. For more detailed information, scan the QR code or visit http://aj.tl/imk.
Follow the specific torque sequence and values provided in the diagram for tightening the cylinder head bolts:
- Step 1: Tighten all cylinder head bolts to 22.5 Nm (16.5 lb.ft) in the specified sequence (refer to diagram for bolt numbering 1-8).
- Step 2: Tighten all cylinder head bolts again to 22.5 Nm (16.5 lb.ft) in the specified sequence.
- Step 3: Turn all cylinder head bolts an additional 90 degrees in the specified sequence.
Always use a calibrated torque wrench for accurate tightening. The torque sequence is critical for even pressure distribution and preventing gasket failure.
Operating Considerations
After installation, it is important to follow proper engine break-in procedures if recommended by the vehicle manufacturer. Monitor coolant levels and engine temperature closely during the initial operation. Check for any leaks around the cylinder head area after the engine has reached operating temperature and cooled down.
Maintenance
Regular engine maintenance, including coolant system checks and proper fluid levels, contributes to the longevity of the cylinder head gasket and overall engine health. Adhere to the vehicle manufacturer's recommended service intervals for optimal performance.
Troubleshooting
If issues arise after installation, such as coolant leaks, oil leaks, or engine overheating, it is crucial to diagnose the root cause promptly. Common issues related to cylinder head gaskets often stem from improper installation, incorrect torque, or surface imperfections. Consult a qualified mechanic for diagnosis and repair.
