pump housing screws.
Check that the oil pump turns freely.
Apply a light coat of oil to the seal lip.
Install the two dowel pins and new O-ring on the oil
pump.
Apply liquid gasket to the cylinder block mating sur-
face of the oil pump.
NOTE:
. Use liquid gasket, Part No. 08718-OOO1.
a Check that the mating surfaces are clean and dry
betore applying liquid gasket.
a Apply liquid gasket evenly, in a narrow bead cen-
tered on the mating surface.
a To prevent leakage of oil, apply liquid gasket to
the inner threads ot the bolt holes.
Do not install the parts if 20 minutes or more have
elapsed since applying liquid gasket. Instead.
reapply liquid gasket aftet removing the old
restclue.
After assembly, wait at least 20 minutes before
filling the engine with oil.

1.Remove the radiator cap, wet its seal with engine
coolant, then install it on the pressure tester.
Apply a pressure ol:
93- 123 kPa(O.95- 1.25 kgJ/cm', 13.5- 1 7.8 psi)
Check for a drop in pressure.

Pressure Testing
1.Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the top of the filler neck.
Attach the pressure tester to the radiator and apply
a pressure of:
93- 1 23 kPa(O.95- 1.25 kgf/cm,. 13.5-17.8 psi)
Inspect for engine coolant leaks and a dfop in
pressure,
Remove the tester and reinstall the radiator cap.
NOTE:
a Check for engine oil in the engine coolant and/or
