Turning the Engine

To turn the crankshaft of a 4-cylinder engine by hand, place a 22 mm wrench on the alternator pulley nut. If the belt slips, press on it.

The cylinder head cover nuts of the 5-cylinder engine must be tightened in the sequence shown, first to 5 N·m, then to 10 N·m, and finally to 12 N·m.

Left: on the 5-cylinder engine, the crankshaft can be turned using the alternator pulley nut (24 mm wrench). If the belt slips slightly, load it by hand.

Right: the crankshaft of the 6-cylinder engine is turned using the central bolt of the crankshaft pulley. Use a 24 mm 12-point socket with a ratchet or breaker bar.

TDC is found when the "O" mark appears on the flywheel below the edge of the transmission housing (arrow).

Left: on 6-cylinder engines, another TDC mark is located on the pulley or the lower timing belt cover (arrows).

Right: at TDC of cylinder 1 ignition, the large holes of the timing plates on both camshaft drive gears point toward the center of the engine (arrow).

For some work, the crankshaft must either be set to a specific position or turned.

PROCEDURE

On a vehicle with a manual transmission, on a level surface, engage fifth gear and roll the vehicle slightly forward or backward.

On the 4-cylinder engine, place a 22 mm crow's foot (offset) wrench on the alternator pulley center nut and turn the engine via the V-belt. If the belt slips, press it between the pulleys with your free hand to tension it.

On the 5-cylinder engine, place a 24 mm open-end wrench on the alternator pulley center nut and turn the engine in the same way as the 4-cylinder engine.

On the 6-cylinder engine, place a 24 mm 12-point socket on the crankshaft pulley center bolt and turn the crankshaft with a ratchet or breaker bar.

Never turn the engine by the timing belt sprocket bolt on the camshaft with the timing belt cover removed! The timing belt may jump teeth, resulting in engine damage.
