Withdrawal
Remove the parts of the front of the engine, do the following:
Remove all attachment drive belts.
Remove the top toothed belt guard.
Using a felt-tip pen, mark the direction of rotation of the toothed belt on its outer side if the belt is to be reinstalled.
Crank the engine until the #1 piston is at TDC. In this case, the indicated marks must match (1, 2, 3, 4).
Loosen vibration damper bolts. With the engine installed, engage a gear and apply the parking brake, or use a socket to hold the crankshaft gear bolt and unscrew the vibration damper bolts. With the engine removed, block the flywheel at the ring gear.
Remove the lower toothed belt guard. Its attachment points are indicated by numbers (1, 2, 3, 4).
Loosen the toothed belt tensioner nut. This requires a TORX key (T45). Press the belt tensioner down in the direction of the arrow to loosen the toothed belt and remove the belt from the gears. If it is to be reinstalled, the belt must not bend or twist.
Installation
To adjust the belt tensioner, a special key is required. This is a digital key that is inserted into both holes in the tension roller. This key is produced by various companies, Hazet designates it with the number 2587.
When installing a new toothed belt, the alignment marks must match, as described in the text. The engine must be at room temperature in order to properly tension the belt. When installing a toothed belt, the following operations must be performed:
Install the toothed belt on the gears of the crankshaft and intermediate shaft without bending it. When installing the old belt, follow the direction of its rotation.
Temporarily put on the vibration damper and secure it with one bolt. To prevent the engine from turning, the alignment mark (TDC) on the camshaft gear (left) should be opposite the arrow on the protective cover of the belt, and the notch on the vibration damper and the alignment mark on the intermediate shaft gear (on right) should be facing each other. If everything matches, put the belt on the camshaft gear.
Now you need to tighten the belt. There is a special key for this (MATRA V 159) insert into the belt tensioner and move in the direction of the arrow until it is possible to rotate the belt between the gears of the camshaft and intermediate shaft by 90°, holding it between the index and thumb fingers. In this position, tighten the 2 bolts (1) torque 20 Nm.
Rotate the crankshaft 2 full turns and check that the tension remains correct.
Remove vibration damper and fit toothed belt cover.
Now fix the vibration damper and tighten its bolts. Lubricate threads and heads of bolts with oil. While holding the crankshaft, tighten the bolts to 90 Nm and from this position tighten another 90°in 2 passes.
Install all drive belts. Install the front parts of the car.

Withdrawal
Disconnect the wire from the minus AB. Using the large bolt on the crankshaft sprocket, rotate the crankshaft. so that the #1 cylinder piston is at TDC for the compression stroke. Align Label "ABOUT" with a label on the cover. If the belt has not skipped, the alignment mark on the back of the camshaft sprocket will align with the upper left edge of the valve cover.
Remove the alternator and A/C compressor drive belts.
Remove the top and bottom timing belt covers.
Loosen the water pump bolts to turn the pump clockwise.
Pull the toothed belt off the sprockets.
Installation
If necessary, rotate the camshaft so that the mark on the back of the sprocket aligns with the left edge of the cylinder head gasket.
Align label if necessary "0" with a label on the cover.
Install the toothed belt and turn the water pump counterclockwise to tension the belt. Tighten water pump bolts to 20 Nm.
Attention. The timing belt is correctly tensioned when it can be twisted 90°midway between the camshaft sprocket and the water pump. Make sure that the belt is not wedged between the oil pump and the sprocket when installing the vibration damper.
Install toothed belt covers and tighten bolts to 10 Nm.
Install the alternator and A/C compressor belts. These belts are properly tensioned when they can be bent 10mm in their middle.
