CAUTION: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.
1. With the vehicle in neutral, position it on a hoist.
2. Remove the RH exhaust manifold.
3. Remove the push rods from the RH cylinder head.
4. Remove the lower intake manifold.
5. Remove the power steering pump.
6. Remove the coolant pump outlet tube.
7. Remove the accessory drive belt tensioner.
8. Remove the parts in the order indicated in the illustration and table.
9. To install, reverse the removal procedure.
10. NOTE: Tighten oil filter one-half turn after gasket makes contact with oil filter housing.
Fill the engine with clean engine oil.
- Drain the engine oil.
- Install a new engine oil filter.
- Fill the engine with clean engine oil.
Item 7: Cylinder Head Bolt Removal Note
1. The lower exhaust manifold studs must be removed to access the cylinder head bolts.
Item 9: RH Cylinder Head Removal Note
1. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.
CAUTION: Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.
NOTE: If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.
Clean the cylinder head-to-cylinder block mating surface of both the cylinder head and the cylinder block.
1. Remove any large deposits of silicone or gasket material with a plastic scraper.
2. Apply silicone gasket remover, following package directions, and allow to set for several minutes.
3. Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4. Apply metal surface prep, following package directions, to remove any traces of oil or coolant, and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
2. Inspect the cylinder head for distortion.
Items 8-7: Cylinder Head Bolt Installation Note
1. CAUTION: Always use new bolts.
NOTE: Lubricate the bolts with clean engine oil prior to installation.
Install the new bolts. Make sure the bolts are installed in the correct locations.
1. Install the new long bolts.
2. Install the new short bolts.
2. Tighten the bolts in the sequence shown in three stages.
- Stage 1: Tighten to 20 Nm (14 ft. lbs.).
- Stage 2: Tighten to 40 Nm (29 ft. lbs.).
- Stage 3: Tighten to 50 Nm (36 ft. lbs.).
3. CAUTION: Each bolt must be loosened and the final tightening carried out prior to working on the next bolt in the sequence. Do not loosen all of the bolts at one time.
Carry out the following final tightening process on each bolt in the sequence shown.
- Long bolts:
- Loosen the long bolt and back out 3 turns.
- Tighten the long bolt to 40 Nm (30 ft. lbs.).
- Tighten the long bolt an additional 180 degrees.
- Go to the next bolt in sequence.
- Short bolts:
- Loosen the short bolt and back out 3 turns.
- Tighten the short bolt to 25 Nm (18 ft. lbs.).
- Tighten the short bolt an additional 180 degrees.
- Go to the next bolt in sequence.
4. Install the exhaust manifold lower studs.
