- Align arrow on timing belt forward.
- Align white lines on timing belt with punch mark on camshaft sprocket and crankshaft sprocket.
- Adjust belt tension with all exhaust side spark plugs removed.
- After removing timing belt, do not rotate crankshaft and camshaft separately, because valves will hit piston heads.

- Cooling fan
- Radiator shroud
- All spark plugs (Exhaust side)
2. Remove the following belts.
- Power steering oil pump drive belt
- Compressor drive belt
