TIMING BELT

CAUTION:
- Do not bend or twist timing belt.
- After removing timing belt, do not turn crankshaft and camshaft separately because valves will strike piston heads.
- Make sure that timing belt, camshaft sprocket, crankshaft sprocket and belt tensioner are clean and free from oil and water.
- Installation should be carried out when engine is cold.





Removal
1. Remove engine under cover.
2. Drain engine coolant from radiator.
Be careful not to spill coolant on drive belts.
3. Remove radiator.
4. Remove engine cooling fan and water pump pulley.
5. Remove the following belts.
- Power steering pump drive belt
- Compressor drive belt
- Alternator drive belt
6. Remove all spark plugs.
7. Remove distributor protector.





8. Remove compressor drive belt idler bracket.
9. Remove fresh-air intake tube for rocker cover.
10. Remove water hose for thermostat housing.

Timing Marks:

11. Set No. 1 piston at TDC on its compression stroke by rotating crankshaft.
12. Remove crankshaft pulley bolt.
13. Remove crankshaft pulley using a suitable puller.
14. Remove front upper and lower belt covers.





- Align punchmark on LH camshaft sprocket with punchmark on timing belt rear cover.
- Align punchmark on crankshaft sprocket with alignment mark on oil pump housing.
- Temporarily install crankshaft pulley bolt on crankshaft so the crankshaft can be rotated.





15. Loosen timing belt tensioner nut, rotate tensioner, then remove timing belt.

Inspection








Visually check the condition of timing belt. Replace if any abnormality is found.

BELT TENSIONER AND TENSIONER SPRING





1. Check belt tensioner for smooth turning.
2. Check condition of tensioner spring.

Installation





1. Confirm that No. 1 piston is set at TDC on its compression stroke.





2. Install tensioner and tensioner spring.
Once stud is removed, apply locking sealant to threads of stud on cylinder block side before installing.





3. Turn tensioner fully outward with hexagon wrench, and temporarily tighten lock nut.





4. Set timing belt when engine is cold.
1) Align white lines on timing belt with punchmarks on camshaft sprockets and crankshaft sprocket.
2) Point arrow on timing belt toward front belt cover.

Tension Adjustment

AFTER BELT REPLACEMENT
If the timing belt was replaced (or to adjust tension on a used belt), follow the steps below.





1. Loosen tensioner lock nut, then turn tensioner clockwise and counterclockwise with hexagon wrench at least 2 times.
2. Tighten tensioner lock nut.
3. Turn crankshaft clockwise at least 2 times, then slowly set No. 1 piston at TDC on its compression stroke.





4. Measure deflection of timing belt midway between camshaft pulleys while pushing with 98 N (10 kg, 22 lbs.) force.
Belt deflection when engine is cold (Reference value): 13 - 15 mm (0.51 - 0.59 inch)/98 N (10 kg, 22 lbs.)
5. If No return to step 1.

AFTER ENGINE OVERHAUL OR ENGINE REASSEMBLY (WITH ROCKER COVERS REMOVED)
If the engine was overhauled or previously disassembled (i.e. intake manifold and/or cylinder head were removed), follow the steps below.
1. Loosen rocker shaft bolts to relieve belt tension caused by the cam shafts.
2. Loosen tensioner lock nut, keeping tensioner steady with hexagon wrench.





3. Turn tensioner 70 to 80 degrees clockwise with hexagon wrench to release belt tension, and temporarily tighten lock nut.
4. Turn crankshaft clockwise at least two times, then slowly set No. 1 piston at TDC on its compression stroke.





5. Push middle of timing belt between RH camshaft sprocket and tensioner pulley with force of 98 N (10 kg, 22 lbs.) to apply tensions on part A and part B.
6. Loosen tensioner lock nut, keeping tensioner steady with hexagon wrench.





7. Set feeler gauge as shown in figure which is 0.5 mm (0.0206 inch) thick and 12.7 mm (0.500 inch) wide.





8. Turn crankshaft clockwise until feeler gauge is positioned as shown in figure.
- Timing belt will move about 2.5 teeth.
9. Tighten tensioner lock nut, keeping tensioner steady with hexagon wrench.
10. Turn crankshaft clockwise or counterclockwise, and remove feeler gauge.
11. Turn crankshaft clockwise at least two times, then slowly set No. 1 piston at TDC on its compression stroke.





12. Measure deflection of timing belt midway between camshaft pulleys while pushing with 98 N (10 kg, 22 lbs.) force.
Belt deflection when engine is cold (Reference value): 13 - 15 mm (0.51 - 0.59 inch)/98 N (10 kg, 22 lbs.)
13. If NG, return to step 1.





14. Install lower and upper belt covers.
