3. Undo the fixing nuts (3a) and remove the mounting bracket (3b) complete with heater plugs control unit.

1. Undo the fixing bolt and nuts (1a) and remove the mounting bracket (1b).

1. Undo the studs on the camshaft housing and remove them.

1. Fit camshaft timing tools (1a) and insert until the cylindrical part of the tool is fully fitted into hole (1c) on the camshaft. Secure the tool in place tightening the tool ring nuts (1d).

With the crankshaft close to T.D.C. the openings in the camshafts are already in the correct position for fitting the timing tools.

1. Undo the nut fixing the timing drive belt tensioner.2. Release the belt from the pullies and remove it.

Refitting ( Removing

) 1. Using the reaction tool (1a) with pins, stop the rotation of the pulley and undo the bolt (1b) fixing the timing drive pulley.

1. Position a hexagonal bolt in the housing for the pulley fixing bolt.2. Position the USAG 452/1 universal extractor and tighten the extractor pin until it is in contact with the bolt positioned previously.3. Continue tightening the tool pin until the camshaft pulley is extraected.

1. Refit the timing pulley (1a) in the housing on the shaft, position the pin (1b) for timing the pulley in relation to the timing sensor, then lock the bolt (1c) fixing the pulley to the shaft.

Before fitting the pulley timing pin, check that the pulley can move freely on the shaft.

1. Rotate the moving tensioner to the position illustrated to facilitate the fitting of the timing belt.

If the mileage of the belt is more than 25,000 km it must be replaced irrespective of its appearance or wear. If it is not being replaced, it should be remembered that the replacement interval for the timing belt and automatic tensioner set out in the maintenance programme is every 240,000 km or 5 years.

1. Fit the timing belt onto the pulleys and gears.

- Remove the timing pin for the timing pulley in relation to the timing sensor.
