Note: Ensure that the cylinder head and the cylinder block sealing surfaces are clear of oil, grease and old gasket material.
- Clean the sealing surfaces
- Inspect the flatness of cylinder head and cylinder block sealing surfaces
- Install EN-301 bridge (2) in compound with GE-571-B gauge (1)
Note: The largest piston projection is decisive for the selection of the cylinder head gasket with the corresponding marking.
- Measure the piston projection dimensions at all pistons.
- Select the cylinder head gasket with the correct identification marks:
| 5.1. | Piston projection 0.028 - 0.127 mm (0.0011 - 0.005), choose cylinder head gasket with identification mark - without holes |
| 5.2. | Piston projection 0.128 - 0.227 mm (0.005 - 0.00894), choose cylinder head gasket with identification mark - one hole |
| 5.3. | Piston projection 0.228 - 0.327 mm (0.00898- 0.01287), choose cylinder head gasket with identification mark - two holes |
- Turn crankshaft in engine direction of rotation until EN-50516 fixing tool (1) to engage with the drilling at flywheel (2) and cylinder block
- Install cylinder head gasket (3)
- Install cylinder head (2)
- Loosely install 8 NEW cylinder head bolts (1)
- Align the cylinder head (1) to the engine block (3) with a straight edge (2)
Note: Use a rubber mallet to adjust the cylinder head. The overhang of the timing side should be under 0.1 mm (0.00394 in).
Caution: Refer to Fastener Caution in the Preface section.
Caution: Refer to Torque-to-Yield Fastener Caution in the Preface section.
- Tighten the 8 cylinder head bolts in sequence as shown and in the following order:
| • | Tighten the bolts in sequence as shown to 40N·m (30 lb ft) |
| • | Tighten in sequence as shown to additional 180° Use EN-470-B torque angle |
