Adjusting the timing belt tension (Hyundai Sonata Y3)

1. Remove the cover covering the hole. (This will be easier if you remove the air conditioner compressor drive belt.).

2. Loosen the timing belt tensioner mounting bolt by 1 or 2 turns.

3. Turn the crankshaft 2 turns clockwise.

4. Tighten the timing belt tensioner mounting bolt.

5. Install the previously removed cover.

Adjusting the tension of drive belts

1. Make sure that the belts are not damaged and are correctly positioned in the pulley grooves.

Warning:

• 1. When installing the V-ribbed belt, make sure that its V-ribs are correctly positioned in the grooves of the pulleys.
• 2. If there is noise or the belt is slipping, check it for wear, damage or breaks on the contact surface with the pulleys, also check the pulleys for grooved wear.

2. Apply a force of 100 N to the middle part of the belt between the pulleys as shown in the figure and measure its deflection.

Normal values:

Note:

• 1. Belt tension should be measured between the marked pulleys.
• 2. When installing a new belt, adjust its tension to the middle value "New". Then let the engine run for 5 minutes or more and check the value.

Adjusting the alternator drive belt and power steering pump

1. To increase the belt tension, slightly loosen the tension pulley mounting nut. Turn the left-hand threaded adjusting bolt in the direction

The material was obtained from a web resource [HYUNDAIBOOK.RU] clockwise and move the tension pulley blindly.



2. Tighten the fastening nut.

• Tightening torque: Alternator drive tension pulley nut - 39-60 Nm.

Note: Insert the adjusting bolt into the slot in the recesses.

Check the belt deflection. Re-adjust if necessary.

Note: Before checking, turn the crankshaft one or more revolutions.

Adjusting the air conditioning compressor belt

1. Loosen the tension pulley mounting bolt A.

2. Adjust the belt deflection with adjusting bolt B.



3. Tighten the mounting bolt A.

4. Check the belt deflection and readjust it if necessary.

Note: Before checking, turn the crankshaft one or more revolutions.
