8 and 12 valve petrol engines
The toothed belt transmission has an automatic belt tensioning device.
If equipped, remove the servo pump V-belt.
Release the water pump belt pulley fastening, while pressing the belt slightly with your hand so that the pulley does not turn.
If equipped, remove the A/C compressor V-belt. Remove the A/C compressor belt pulley bracket.
Remove the alternator V-belt, see p. 1.21.
Remove the upper timing belt cover.
Remove the lower timing belt cover.
Remove the caps from all spark plugs and unscrew all spark plugs with a spark plug wrench.
Turn the crankshaft clockwise, checking the condition of the toothed belt. Note: The gearbox must be in neutral and the handbrake must be engaged. Turn the crankshaft using the head on the central bolt. Always turn the crankshaft clockwise. For turning the engine, see the section "Removal and installation the timing belt".
Set the engine shaft to the top dead center (TDC) of cylinder 1. To do this, turn the crankshaft to the position where the marking on the camshaft matches the corresponding mark.
Caution: Rotate the pulley only clockwise, otherwise the toothed belt tension will be disrupted. Do not rotate the engine by the camshaft, as this will overload the toothed belt.
Loosen both timing belt tensioner bolts enough to allow the tensioner to move.
Turn the crankshaft slightly clockwise so that the camshaft gear rotates by 2 teeth (18°).
In this position, press the tensioner in the direction of the arrow (see Fig. K-1037). This will achieve a position where the individual gears remain engaged with the toothed belt.
Then release the belt tensioner so that the belt is tensioned only by the spring.
Tighten the belt tensioner fastening. First tighten the bolt in the slot -in the picture on the right-. Then tighten the pivot bolt -in the picture on the left-.
Caution: Never tighten the pivot bolt first, as this will cause the belt tensioner to rotate and the belt to become overtightened.
Check the belt tension again. To do this, as shown in the figure, press the belt with your finger at about the middle of the belt tensioner. The belt should bend to about ¼ of the width of the head of the belt tensioner clamp bolt.
Install the spark plugs. Place the spark plug caps in the correct firing order, see p. 1.2.
Install the lower timing belt cover.
Install the upper timing belt guard.
Secure the air conditioning compressor belt pulley bracket.

Install the water pump belt pulley.
Install the V-belt, see p. 1.21.
16-valve petrol engine (1.6, 1.8 l)
The 16-valve engine has a hydraulic belt tensioner that ensures a constant belt tension. Adjusting the toothed belt tension is only done after removing and installing the toothed belt. Since this work requires a certain amount of experience and special tools, it should be entrusted to a specialist.
