Oil Pan

Installation

Install the oil pan in the reverse order of removal:

• Always use new O-rings.

• Oil pan and cylinder block mating surface must be

clean.

1. Apply liquid gasket to the cylinder block, then install

the oil
pan.

NOTE:

• Use liquid gasket, Part No. 08718 - 0001 or 08718

0003.

• Check that the mating surfaces are clean and dry

before applying liquid gasket.

• Apply liquid gasket evenly, being careful to cover

all the mating surface.

• Do not apply liquid gasket to O-ring grooves.

• To prevent oil leakage, apply liquid gasket to the

inner threads of the bolt holes.

• Do not install the parts if 5 minutes or more have

elapsed since applying liquid gasket.

Instead, reapply liquid gasket after removing old

residue.

•
After assembly,
wait
at
least
30
minutes before
fill-

ing the engine with oil.

2. Apply a pressure of 93- 123 kPa (0.95- 1.25 kgf/cm2,

14-18 psi).

3. Check for a drop in pressure.

4. If the pressure drops, replace the cap.
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.

2. Attach the pressure tester to the radiator and apply

a pressure of 93-123 kPa (0.95 - 1.25 kgf/cm2, 14 -

18
psi).
