You will need:
Note: Directions such as left are when looking at the vehicle from the front
Jack the car up and support it on axle stands, you may wish to remove the wheel arch liner on the left hand wheel for extra space but this is not essential.
Remove the upper timing belt cover (this is located on the left hand side of the engine). There is a small bolt on the front and one on the back. Lock the camshaft using the timing hole on the pulley and lock the flywheel in position using the hole in the front of the block *This is very important!* To ensure that the timing holes line up, it will be necessary to rotate the engine. Do this using a socket and bar on the crankshaft pully IN A CLOCKWISE DIRECTION. Taking the spark plugs out will make the engine easier to rotate.
Disconnect the battery negative terminal and undo the two conections from the alternator, you will notice that these wires pass through two clips on the plastic engine cover, unclip them and position the wires out of the way.
To remove the remaining covers you will need to remove the crankshaft pulley wheel, this is at the very base of the engine and has three bolts going through it, slacken the alternator belt and slide it off the pulley then undo the three bolts and remove the pulley. Now remove the remaining bolts from the plastic covers and remove them.
You should now see the timing belt assembly
To remove the belt you must loosen its tensioner wheel, this wheel has a small square hole in it and is towards the rear of the engine, loosen the nut slightly and rotate the wheel upwards. The belt should now slide off the rest of the pulleys, note how its fitted (Do not remove the timimg lock or rotate any part of the engine until the new belt is fitted)
Now place the new belt in position over the pulleys ensuring that the arrow marked on it is facing the front of the car (the tensioner wheel should be the only pulley on top of the belt) Also make sure that you first ensure that the longest run of the belt (between the cam pully and the crankshaft pully)is put on first. Then you can allow the tensioner to take the “slack” up.
Find an allen key that fits fairly snug in the square hole on the tensioner wheel, Use this as a lever to rotate the wheel down onto the belt, when the square hole is at the very bottom of the wheel tighten the nut.
We now need to check the tension of the belt. To do this grip the belt between the thumb and forefinger in the middle of its longest stretch (at the very front of the engine) and gently twist the belt, it should twist approximately 90' either way if not then retension the belt by adjusting the pressure of the tensioner wheel accordingly.
Once the correct tension is acheived, ensure the tensioner wheel is done up tightly and remove the locking pins from both fly and cam sprocket. You now need to turn the engine by hand in a clockwise direction using a large spanner or socket on the end of the crankshaft (do not attempt to turn the engine in any other manner), you need to turn it three full revolutions to settle the cam belt
Now re-check the tension as before and adjust if neccesary. Once tensioned, the covers for the cam pulley can be replaced and the car lowered to the ground
NB: Ensure all locking tools are removed before turning or starting the engine
