50. If the timing marks do not line up correctly, turn either of the camshafts or the crankshaft to line up the marks.
NOTE: Ensure that the timing marks on the camshaft sprockets are aligned with the marks on the rear engine front cover. Also check that the timing mark on the crankshaft is aligned with the mark on the oil pump housing.
51. Install the timing chain/belt starting at the crankshaft sprocket and moving around to the camshaft sprockets in a counterclockwise direction. Do not allow any slack in the timing chain/belt between the crankshaft sprocket and camshaft sprockets. After all of the timing marks are matched up with the timing chain/belt installed, slip the timing chain/belt onto the timing chain/belt tensioner.
CAUTION: Pay special attention to the tooth shape of the timing chain/belt. The current timing chain/belts are not interchangeable with the timing chain/belts from the 1993 model year. The 1993 model year uses a square or trapezoidal tooth timing chain/belt while the current model year uses a rounded tooth design. The design change was made to extend the service life of the timing chain/belt from 60,000 miles for the square or trapezoidal toothed belt to 105,000 miles for the rounded tooth belt. If the proper timing chain/belt is not used, the customer may complain of a "whining" noise coming from the engine compartment. If the camshaft sprocket has a square cut in the valley of the gear tooth, it will require a square or trapezoidal tooth timing chain/belt. If the camshaft sprocket has a rounded cut in the valley of the gear tooth, it will require a rounded tooth timing chain/belt.
(Part 2 Of 2):
NOTE:
- If a new timing chain/belt is to be installed, make sure that the arrow is pointing away from the engine. If a timing chain/belt is to be reused, make sure that the directional arrow that was marked during disassembly is facing the correct direction.
- A new timing chain/belt has three white timing marks that indicate the correct timing positions of the camshafts and the crankshaft. These marks will help ensure that the engine is timed properly. When the engine is properly timed each white timing mark on the timing chain/belt will be aligned with the corresponding camshaft and crankshaft timing mark on the crankshaft sprocket and the camshaft sprockets. Because the white timing marks are not evenly spaced you will need to refer to the illustration for proper timing chain/belt placement. There should be 40 timing belt teeth between the timing marks of the front and rear camshaft sprockets and 43 teeth between the timing mark on the front camshaft sprocket and the timing mark on the crankshaft sprocket.
- Verify that the camshaft timing marks are aligned with the timing marks on the seal plate, and that the crankshaft sprocket timing mark is aligned with the timing mark on the oil pump.

a. Install a 0.35 mm (0.0138 inch) thick and 12.7 mm (0.500 inch) wide feeler gauge as shown.
b. Turn the crankshaft sprocket clockwise to position the feeler gauge between the timing chain/belt tensioner Timing chain/belt tensioner and the timing chain/belt.
