PROCEDURE

On the back of the crankshaft timing belt sprocket, align the mark with the upper left edge of the cylinder head cover (observe through the small slot). When turning the camshaft, no piston must be at TDC, otherwise the valves or piston crowns may be damaged.

Crankshaft: align the TDC mark on the flywheel with the mark in the observation hole of the clutch housing. Or use the timing mark on the V-ribbed belt pulley.

Fit the timing belt onto the camshaft, tensioner roller and water pump, without changing the positions of the camshaft and crankshaft any further.

Tension the timing belt.

Turn the engine two revolutions and check the valve timing again.

Check the position of the distributor, as described for the 4-cylinder engine.

Set the ignition timing.
