Cylinder Head - Installation

INSTALLATION










NOTE: The cylinder head bolts (4) are tightened using a torque plus angle procedure. The bolts must be examined BEFORE reuse. If the threads are necked down the bolts must be replaced

Necking can be checked by holding a straight edge against the threads. If all the threads do not contact the scale, the bolt must be replaced.

CAUTION: When cleaning cylinder head and cylinder block surfaces, DO NOT use a metal scraper because the surfaces could be cut or ground. Use ONLY a wooden or plastic scraper.

1. Clean sealing surfaces of cylinder head and blockEngine Gasket Surface Preparation.
2. Lubricate bolt threads with clean engine oil and install bolts.
3. Install new head gasket over locating dowels.





4. Install cylinder head to block, assuring head is properly positioned over locating dowels.
5. Tighten bolts in sequence shown, using the following steps and torque values:
- Step 1: Bolts 1-8 to 48 Nm (35 ft. lbs.)
- Step 2: Bolts 1-8 to 75 Nm (55 ft. lbs.)
- Step 3: Bolts 1-8 to 75 Nm (55 ft. lbs.)
- Step 4: Bolts 1-8 to +90° Turn Do not use a torque wrench for this step.
- Step 5: Bolts 9-11 to 28 Nm (250 in. lbs.)
