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.

[When removing the drive belt from the bottom of the vehicle]

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.

- Inspection Drive Belt Inspection

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.

- Inspection Check the drive belt tensioner for excessive foreign substances, crack, damage or sticking of pivot shaft. Replace if necessary.

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.

- Inspection Check the crankshaft damper pulley for vibration in rotation, oil or dust deposit of V-ribbed part. Replace if necessary.

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.

Hyundai Accent (HC) (2017 - 2022) Service Manual: ETC (Electronic Throttle control) System

- Description The Electronic Throttle Control (ETC) System consists of a throttle body with an integrated control motor and throttle position sensor (TPS). Instead of the traditional throttle cable, an Accelerator Position Sensor (APS) is used to receive driver input. The ECM uses the APS signal to calculate the target throttle angle; the position of the throttle is then adjusted via ECM control of the ETC motor.
