Be careful when loosening the drain bolt whils theengine is hot. Burns can resuh because the oil tem-peratu16 is very high.
Remove the oil filter with the oil filter wrencn.
Inspect the threads and rubber seal on the new filter.Wipe off the seat on the engine block, then apply alight coat of oil to the new filter,s rubber seal.
NOTE: Use onty fitters with a built-in bypass sys,tem.

18. Check that the oil pump turns freely.
19. Apply a light coat of oilto the seal lip.
20. Install the two dowel pins and new O-ring on the oilpump.
21. Apply liquid gasket to the cylinder block mating sur_face of the oil pump.
NOTE:
. Use liquid gasket, Part No.08718 - oOOj or 08718- 0003.. Check that the mating surfaces are clean and drybefore applying liquid gaskel. Apply liquid gasket evenly, in a narrow bead cen-tered on the mating surface.o To prevent leakage of oil, apply liquid gasket tothe inner threads of the bolt holes.. Do not install the parts if five mtnures or morehave elapsed since applying liquid gasket.Instead. reapply liquid gasket after removing theold residue.
. After assembly, wait at least 30 minutes beforefilling the engine with oil.
