Warning: Allow the engine to cool completely before performing this procedure.
Removal
1. Drain the coolant (see chapter 1).
2. Remove the drive belt (see chapter 1).
3. Remove the radiator fan together with the shroud (see chapter 3).
4. Remove the cooling system pump (see chapter 3), as well as the power steering pump (see chapter 10).
5. Remove the crankshaft pulley (see subsection 11).
6. Remove the engine sump (see subsection 16).
7. Remove the front shroud bolts, starting with the 7mm bolt located in the center.
8. Insert two bolts into the holes in the front casing intended for mounting fasteners. Gradually tighten the bolts, thus removing the casing.
9. If necessary, remove the oil pump from the front casing (see subsection 12).
10. Clean the mating surface of the front housing with solvent, removing any remaining gasket material. Inspect the surface for chips and other types of damage.
Note: To avoid damaging the surface of the casing, do not use power tools when cleaning (wire brush or disc with electric drill).
Installation
11. Align the splined connection of the oil pump and crankshaft (to do this, you will have to temporarily install a casing without a seal).
12. Remove the casing and apply a 5mm thick bead of RTV sealant to the mating surface and to the areas around the three bolt holes located inside.
13. Place the front engine cover in its original location without disturbing the alignment of the splines of the oil pump and crankshaft. Temporarily install the crankshaft pulley and center the seal on it to align the position of the front cover.
14. Tighten all bolts finger tight and then to the specified torque. The last thing to tighten is the central bolt with a diameter of 7 mm (located just above the center line of the crankshaft).
15. The rest of the installation is carried out in the reverse order of removal. Fill with engine oil and coolant (see chapter 1), start the engine and check for leaks.
