Timing Belt: Service and Repair

TIMING BELT AND BELT TENSIONER

Remove or Disconnect

1. Crankshaft pulley.
2. Retaining clips and engine wiring harness from timing belt cover.

Timing Belt, Tensioner & Camshaft Gear:

3. Seven bolts, one nut and timing belt cover from vehicle.

Important

Timing Belt Alignment Marks:

- Before removing timing belt, align four timing marks by turning crankshaft.

Timing Belt Tensioner & Belt:

4. Timing belt tensioner, tensioner plate, tensioner spring, spring damper and timing belt from cylinder block.

Allowable Turning Range:

NOTICE: After timing belt is removed, never turn camshaft and crankshaft independently. If turned, interference may occur among pistons and valves, and parts related to pistons and valves may be damaged.

Inspect
- Timing belt for wear or cracks. Replace it as necessary.
- Timing belt tensioner for smooth rotation.

Install or Connect

Timing Belt Tensioner & Tensioner Plate:

1. Tensioner plate to timing belt tensioner. Insert tensioner plate lug into the timing belt tensioner hole.

Timing Belt Tensioner Installation:

2. Timing belt tensioner and tensioner plate to cylinder block; secure with one bolt and one stud. Do not tighten fully. check to make sure that plate movement in direction of arrow causes tensioner to move in the same direction. If it does not, remove timing belt tensioner and tensioner plate and reinsert tensioner plate lug in timing plate tensioner hole.

Upper Timing Marks:

3. Check that timing mark on camshaft timing belt pulley is aligned with "V" mark on cylinder head cover. If not, align the two marks by turning the camshaft but be careful not to turn it more than its allowable turning range.

Lower Timing Marks:

4. Check that punch mark on crankshaft timing belt pulley is aligned with arrow mark on oil pump case. If not, align the two marks by turning crankshaft but be careful not to turn it more than its allowable turning range.

Timing Belt Tensioner Installation:

5. Timing belt, tensioner spring, and spring damper. With two sets of marks aligned and tensioner plate pushed up, install timing belt on two pulleys in such a way that drive side of belt is free from any slack. Then install the tensioner spring and spring damper. Hand tighten tensioner stud only.

Important
- When installing timing belt, match arrow mark on timing belt with rotating direction of crankshaft.
- In this state, the number one piston is at top dead center of the compression stroke.

Timing Belt Tensioner Bolt & Stud:

6. To take up slack in timing belt, turn crankshaft two rotations clockwise after installing it. After making sure that belt is free from slack, tighten timing belt tensioner stud first and. tensioner bolt.

Tighten
- Timing belt tensioner stud to 11 N.m (97 lb. in.).
- Timing belt tensioner bolt to 27 N.m (20 lb. ft.).

7. Confirm again that both sets of timing marks are aligned properly.

Important
- Before installing timing belt cover, make sure that seal is between coolant pump and oil pump case.

8. Timing belt cover; secure with seven bolts and one nut.

Tighten
- Turning belt cover nut and bolts to 11 N.m (97 lb. in.).

9. Crankshaft pulley.
