2. Remove the windshield wiper arms (see WIPER MOTOR REPLACEMENT ).

3. Remove the engine cover, right upper fender trim, battery trim, and left upper fender trim, then

remove the upper grille cover and cowl cover (see step 3 under ENGINE REMOVAL ).

4. Remove the under-hood fuse/relay box, connector, and transfer breather hose from the strut brace,

then remove the strut brace (see step 18 under ENGINE REMOVAL ).

5. Remove the connector bracket from the front cylinder head; use the bracket bolt hole to attach engine

balance bar front arm (see step 55 under ENGINE REMOVAL ).

6. Remove the engine mount control solenoid valve bracket from the rear cylinder head; use the bracket

bolt hole to attach engine balance bar rear arm (see step 56 under ENGINE REMOVAL ).

7. Lift and support the engine with engine hanger and engine balance bar. Attach the front arm to the

front cylinder head with a spacer and the 10 x 1.25 mm bolt. Attach the rear arm to the rear cylinder
head with the 8 x 1.25 mm bolt (see step 57 under ENGINE REMOVAL ).

8. Remove the timing belt (see TIMING BELT REMOVAL ).

9. Remove the crankshaft position (CKP) sensor (see CKP SENSOR REPLACEMENT ).

10. Remove the rocker arm oil control solenoid/oil filter assembly (see step 9 under CRANKSHAFT

AND PISTON REMOVAL ).

INSPECTION

1. Remove the screws from the pump housing, then separate the housing and cover.

2. Check the inner-to-outer rotor radial clearance between the inner rotor (A) and outer rotor (B). If the

inner-to-outer rotor clearance exceeds the service limit, replace the oil pump assembly.

Inner Rotor-to-Outer Rotor Radial Clearance

Standard (New): 0.04-0.16 mm (0.002-0.006 in.)

5. Inspect both rotors and pump housing for scoring or other damage, Replace the parts, if necessary.

6. Apply liquid thread lock to the pump housing screws, then install the oil pump cover.

7. Make sure the oil pump turns freely.

INSTALLATION

1. Remove the old oil seal from the oil pump.

2. Gently tap in the new oil seal until the oil seal driver bottoms on the pump.

3. Remove all of the old liquid gasket from the oil pump mating surfaces, bolts, and bolt holes.

4. Clean and dry the oil pump mating surfaces.

5. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the engine

block mating surface of the oil pump. Install the component within 5 minutes of applying the liquid
gasket.

NOTE:



If you apply liquid gasket P/N 08718-0012, the component must be
installed within 4 minutes.



If too much time has passed after applying the liquid gasket,
remove the old liquid gasket and residue, then reapply new liquid
