2. Disconnect negative battery cable.
3. Remove both cylinder head covers and loosen the rocker arm assemblies.
4. Remove the front timing belt cover See: Timing Cover/Service and Repair/Timing Cover - Removal.
5. Mark belt running direction, if timing belt is to be reused.
CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or
piston damage.
6. Rotate engine clockwise until crankshaft (10) mark aligns with the TDC mark on oil pump housing (9) and the camshaft sprocket (2, 7) timing
marks (1, 8) are aligned with the marks on the rear cover.
7. Remove the timing belt tensioner (12) and remove timing belt.
8. Inspect the tensioner for fluid leakage.
