1. Use a 10 mm socket wrench to loosen plug 1 of the timing belt tensioner screw, then use an 8 mm wrench to unscrew the two bolts 2 securing the tensioner to the cylinder block.
2. Remove the tensioner from the cylinder block.
Attention! With the timing chain tensioner removed, do not turn the crankshaft.
Using a slotted screwdriver with a thin blade, turn the screw counterclockwise. In this case, the tensioner rod should sink into the housing.
In the extended position, the stem should not sink when pressed.
And should be pushed out under the action of a spring from a recessed position.
Before assembly, remove the remains of the old gasket from the tensioner housing and the mounting hole on the engine. Using a slotted screwdriver, turning the screw inside the tensioner counterclockwise, recess the tensioner rod. We put a new gasket on the tensioner housing and install it on the engine. Tighten the mounting screws. After releasing the rod, turn the screw clockwise half a turn and tighten the screw plug.
