Drive Belt

- Removal and Installation * There are two methods to when removing the drive belt.[When removing the drive belt from the top of the vehicle]

1.Install the wrench to the drive belt tensioner repair hole (A) and turn it clockwise.

• Fix the drive belt tensioner by installing fixing pin (B) after turning the drive belt tensioner to clockwise.

• Use fixing pins that have the same outer diameter as a 6mm(0.2362 in.) hex wrench or a 6mm(0.2362 in.) hex wrench.

2.Remove the drive belt (A).

• When removing the drive belt, remove the drive belt from the water pump pulley.

3.Install in the reverse order of removal.

• When installation of drive belt, make the drive belt as a round hook shape bigger than alternater pulley as a picture down below. Then install it with following order of alternator → airconditioner compressor → crankshaft damper pulley → water pump → drive belt tensioner.

1.Remove the engine room under cover.(Refer to Engine and Transaxle Assembly - "Engine Room Under Cover")

2.Turn the spanner to clockwise after installing it to drive belt tensioner arm boss (A).

• Fix the drive belt tensioner by installing fixing pin (B) after turning the drive belt tensioner to clockwise.

• Use fixing pins that have the same outer diameter as a 6mm(0.2362 in.) hex wrench or a 6mm(0.2362 in.) hex wrench.

3.Remove the drive belt (A).

• When removing the drive belt, remove the drive belt from the water pump pulley.

4.Install in the reverse order of removal.

• When installation of drive belt, make the drive belt as a round hook shape bigger than alternater pulley as a picture down below. Then install it with following order of alternator → airconditioner compressor → crankshaft damper pulley → water pump → drive belt tensioner.

1.Visually check the belt for excessive wear, frayed cords etc.If any defect has been found, replace the drive belt.

• Cracks on the rib side of a belt are considered acceptable. If the belt has chunks missing from the ribs, it should be replaced.

Drive Belt Tensioner

- Removal and Installation

1.Remove the drive belt.(Refer to Timing System - "Drive Belt")

2.Remove the drive belt tensioner (A).

Tightening torque Bolt (B) : 18.6 - 23.5 N.m(1.9 - 2.4 kgf.m, 13.7 - 17.4 lb-ft)Bolt (C) : 34.3 - 41.2 N.m(3.5 - 4.2 kgf.m, 25.3 - 30.4 lb-ft)

3.Install in the reverse order of removal.

Crankshaft Damper Pulley

- Removal and Installation

1.Remove the engine room under cover.(Refer to Engine and Transaxle Assembly - "Engine Room Under Cover")

2.Remove the drive belt.(Refer to Timing System - "Drive Belt")

3.Remove the crankshaft damper pulley (A).

Tightening torque :66.7 - 70.6 N.m + 98 - 102°[6.8 - 7.2 kgf.m + 98 - 102°, 49.2 - 52.1 lb-ft + 98 - 102°]

• Fix the ring gears using the SST (09231-2B100,09231-3N100) after removing the starter. Then remove the crankshaft damper pulley.

4.Install in the reverse order of removal.

Front Oil Seal

- Replacement

1.Remove the engine room under cover.(Refer to Engine and Transaxle Assembly - "Engine Room Under Cover")

2.Remove the drive belt.(Refer to Timing System - "Drive Belt")

3.Remove the crankshaft damper pulley.(Refer to Timing System - "Crankshaft Damper Pulley")

4.Remove the front oil seal (A).

5.Using the SST (0K231-2C200), install a new front oil seal.

• Always use a new front oil seal.

6.Install in the reverse order of removal.
