| NOTE: |
Left side shown, right side similar. |
- If removed, using a new exhaust manifold gasket, position the exhaust manifold and install the retaining bolts finger tight.
- Using the sequence shown, tighten the exhaust manifold retaining bolts to the proper
NOTE: The cylinder head gaskets are not interchangeable between left and right sides. They are marked “T” for top, “B” for bottom, “L” for left side and “R” for right side.
- Clean all sealing surfaces of the engine block and the cylinder head(s) (2).
NOTE: Rotate crankshaft 45° so that all pistons are 1/2 the way down the cylinder bore to avoid piston to valve contact.
- Position the new cylinder head gasket(s) (1) onto the engine block.
- Position the cylinder head(s) (2) onto the engine block.
- Install the cylinder head bolts finger tight.
- Using the sequence below, tighten the retaining bolts.
- Using the sequence shown, tighten bolts 1-10 to 34 N·m (25 ft. lbs.).
- Using the sequence shown, tighten bolts 11-15 to 20 N·m (15 ft. lbs.).
- Using the sequence shown, tighten bolts 1-10 to 54 N·m (40 ft. lbs.).
- Using the sequence shown, tighten bolts 1-10 to 61 N·m (45 ft. lbs.).
- Using the sequence shown, rotate bolts 1-10 an additional 90 degrees.
- Using the sequence shown, tighten bolts 11-15 to 28 N·m (21 ft. lbs.).
- Install the push rods and rocker arms
- Install the power steering pump
- Install the catalytic converters
- Lower the vehicle.
- Install the supercharger assembly
- Fill cooling system
NOTE: Evacuating or purging air from the charge air cooling system must be done with the use of a pressurized air operated vacuum generator.
