1. Rotate the crankshaft in a clockwise direction until the camshaft lobes at number 3 and 4 cylinders are angled upwards. Fit the camshaft Locking Tools B over the camshaft lobes on cylinder numbers 3 and 4. Gently rock the Crankshaft until the tools can be ﬁtted snugly and tightened in position using the integral adjuster. Remove the blanking plug from the cylinder block position rear left hand side and replace with the Crankshaft Locking Tool A

2. Remove the centre blanking cap and circlip from each camshaft sprocket and slightly slacken the centre bolt.Using an 8mm Hex Key turn the Tensioner Pulley anti-clockwise until the holes in both Tensioner Body and Pushrod are aligned and retain in this position with the Tensioning Pin D. Once the Tensioner Pulley Bolt has been slackened the Timing Belt can be removed. During the installation of the new timing belt it is necessary to turn the Camshaft Sprockets using tool C with a torque of 10 Nm. After tightening each Camshaft Sprocket Bolt the Blanking Caps can be re-ﬁtted with the circlips to retain.

3. The Camshaft and Crankshaft Locking Tools should be removed and the ﬁnal installation procedure followed.Support Guides (Optional Set) can be used to slide the front panel forward to provide additional working space. Remove Timing Belt covers and rear engine cover and move the coolant expansion tank to one side, it is unnecessary to disconnect the hoses.
