Timing Belt: Installation

CAUTION: Make sure the arrow on the timing belt is pointing away from the engine when installed.

CAUTION: A new timing belt has three white timing marks that indicate the correct timing positions of the camshafts and the crankshaft. These marks will help make sure that the engine is timed correctly. When the engine is correctly timed each white timing mark on the timing belt will be aligned with the corresponding camshaft and crankshaft timing mark on the crankshaft sprocket and the camshaft sprockets. There should be 40 timing belt teeth between the timing marks on the LH and RH camshaft sprockets and 43 teeth between the timing mark on the LH camshaft sprocket and the timing mark on the crankshaft sprocket.

CAUTION: It is necessary to 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.
When installing the timing belt, start at the crankshaft sprocket moving around to the camshaft sprockets in a counterclockwise direction. Do not allow any slack in the timing belt between the crankshaft sprocket and camshaft sprockets. After all of the timing marks are matched up with the timing belt installed, slip the timing belt onto the timing belt tensioner.
