This adjustment is to be made with a cold engine. A suitable temperature is approximately 20°C/68°F.
At higher temperatures, for example with engine at operating temperature or at higher ambient temperature, the needle is further to the right.
The position of the needle, when aligning the camshaft belt tensioner at different engine temperatures, is shown in the illustration.
Tighten the timing belt:
There are two variants of the belt tensioner.
From engine number 3188688 the eccentric must be turned anticlockwise to tighten the belt.
From engine number 3188689 the eccentric must be turned clockwise to tension the belt.
turn the crankshaft clockwise carefully until the camshaft belt is tensioned. The belt should be tight between the intake camshaft pulley, idler
pulley and crankshaft.
hold the center screw on the belt tensioner in position and turn the eccentric on the belt tensioner clockwise/anticlockwise, depending on the
variant, until the tensioner's needle passes the marked position.
Then turn the eccentric back so that the indicator reaches the marked position in the center of the window.
Secure the eccentric and tighten the center screw to 20 Nm.
Check that the needle is in the correct position.
