Timing Component Alignment Marks: Locations

CAUTION: Incorrect removal or installation of the timing belt can result in damage to internal engine components.

For complete Timing Belt Removal and Installation information, please refer to Timing Belt; Service and Repair. Service and Repair

TIMING BELT
a. Check the timing belt idlers No.1 and No.2.
1 Visually check the seal portion of the idler pulley for oil leakage.
If leakage is found, replace the idler.
2 Check that the idler turns smoothly.
If necessary, replace the idler.





b. Check the water pump.
1 Visually check the air hole and water hole for coolant leakage. If leakage is found, replace the water pump and timing belt.
2 Turn the pulley, and check that the water pump bearing moves smoothly.
If necessary, replace the water pump.
c. Remove any oil or water on the crankshaft pulley, oil pump pulley, water pump pulley, idler No.1 and idler No.2, and keep them clean.

NOTICE: Only wipe the pulleys; do not use any cleansing agent.





d. Set the No.1 cylinder to the TDC/compression.
1 Turn the hexagonal portion of the camshaft to align the timing marks of the camshaft timing pulleys and timing belt plates.





HINT: By turning the camshaft timing pulleys clockwise as follows, installation of the timing pulleys will be easy:
1/2 teeth turn for the left bank camshaft timing pulley
1 tooth turn for the right bank camshaft timing pulley





2 Using the crankshaft damper bolt, turn the crankshaft to align the timing marks of the crankshaft timing pulley and oil pump body.





e. Install the timing belt.
1 Remove any oil or water on the each pulley, and keep them clean.

NOTICE: Only wipe the pulleys; do not use any cleansing agent.

2 Face the front mark (arrow) on the timing belt forward.
3 Put the timing belt on the crankshaft timing pulley.
^ Align the installation mark on the timing belt with the timing mark of the crankshaft timing pulley.
4 Put the timing belt on the idler No.2.
5 Put the timing belt on the camshaft timing pulley (LH bank).
^ Align the installation mark on the timing belt with the timing mark of the camshaft timing pulley.
6 Put the timing belt on the water pump pulley.
7 Put the timing belt on the camshaft timing pulley (RH bank).
^ Align the installation mark on the timing belt with the timing mark of the camshaft timing pulley.
8 Put the timing belt on the idler No.1.





f. Set the belt tensioner.
1 Using a press, slowly press in the push rod using 981 to 9,807 N (100 to 1,000 kgf, 220 to 2,205 lbs.) of pressure.
2 Align the holes of the push rod and housing, and pass a 1.27 mm hexagon wrench through the holes to keep the setting position of the push rod.
3 Release the press.
4 Install the dust boot to the belt tensioner.





g. Install the belt tensioner.
1 Temporarily install the belt tensioner with the 2 bolts.
2 Alternately tighten the 2 bolts.
Torque: 26 Nm (270 kgf-cm, 19 ft. lbs.)
3 Using pliers, remove the 1.27 mm hexagon wrench from the chain tensioner.





h. Check the valve timing.
1 Using the crankshaft damper bolt, slowly turn the crankshaft pulley 2 revolutions from the TDC to TDC.

NOTICE: Always turn the crankshaft pulley clockwise.





2 Check that each pulley is aligned with each timing mark as shown in the illustration.
If the timing marks are not aligned, remove the timing belt and reinstall it.
3 Remove the crankshaft damper bolt.
