Removing

- Remove ribbed belt.
- Remove camshaft drive belt.






- Remove crankshaft toothed belt sprocket by counterholding sprocket with 3415.
- Remove oil pan.
- Unbolt front sealing flange.
- Remove sealing flange (release using light blows from rubber hammer, if necessary).

Installing

Note:

^ Check expiration date on sealant before using.
^ Install the sealing flange within 5 minutes of applying the silicone sealant.






- Cut-off tube nozzle at forward mark (nozzle diameter approx. 3 mm, or 1/8 in.)
- Apply silicone sealing compound, as shown, to clean oil pan sealing surface. Sealing compound bead must be:
Continuous, passing inside of bolt holes in oil pan (arrows)
Thickness of sealant bead (arrows): 2 to 3 mm (3/32 to 1/8 in.)

Note:
- The sealing bead must not be thicker than the specification, otherwise excess sealing compound could enter the sump and block the oil suction pipe strainer.






- Apply silicone sealant bead (as shown) to a clean sealing surface on sealing flange.
- Immediately install sealing flange and slightly tighten all bolts.

Note:
- Use guide sleeve from 2080A to install sealing flange with oil seal already installed.

- Tighten sealing flange mounting bolts using alternate sequence.
Tightening torque: 15 Nm (11 ft. lbs.)
- Install oil pan.

Note:
- After installing, allow sealant to dry for approx. 30 minutes before filing with engine oil.






- Install crankshaft toothed belt sprocket and hold with 3415 counter-hold.
Tightening torque: 90 Nm (66 ft. lbs.) + 1/4 turn (90°)
- Install toothed belt and adjust timing.
- Install ribbed belt.
