Working on the special tool, rotate the crankshaft in a clockwise direction until the piston for cylinder no. 1 is at T.D.C. in the explosion stroke.

If TDC is exceeded, do not turn backwards, but proceed by rotating the crankshaft through a further two revolutions in the same direction until the piston for cylinder no. 1 is at TDC.

1. Slacken the nut on the timing belt moving tensioner.2. Prise off and remove the timing belt.
