Removing

–  Unscrew the fastening bolts -arrows- and remove the engine noise damping cover.

–  Unscrew the right-hand noise damping -fastening points 1 ... 3-. –  Remove the ribbed-belt → Chapter.

–  Position the support -U 30025E-. –  Fit the spindle hook -A- into the socket and tighten slightly. –  Release the coolant expansion tank and lay to side. –  Release the vacuum pipe for the carbon filter system. –  Remove the clips from the upper timing belt guard and remove the cover.

–  Position the crankshaft at TDC -arrow-.

–  Check that the mark on the camshaft sprocket is lined up with the mark on the guard -arrows-.

–  Unscrew the bolts -arrows- securing the drive train, engine side.

–  Unscrew the bolts -arrows- and remove the Poly V-belt tensioner. –  Remove vibration damper / pulley → Chapter.

–  Remove the fastening bolts of the console to the engine block -arrows-. –  Remove notched belt guard centre and lower parts. –  Mark the toothed belt D.O.R.

–  Loosen bolt -3- and turn the tensioning device nut using the turning tool -T20197--in the direction of arrow B-. –  Detach notched belt.   Note t  If the camshaft turns, the crankshafts is not at TDC. Danger of valve/piston crown damage. t  Turn crankshaft back slightly. Fitting   Note Respect the timing belt D.O.R. - risk of breaking.

–  Check that the mark on the camshaft sprocket is lined up with the mark on the guard -arrows-.

–  Position the crankshaft at TDC -arrow-. –  Fit the timing belt on the crankshaft sprocket (observe direction of rotation). –  Fit the timing belt onto coolant pump, the tensioning roller and camshaft sprocket. Tightening

–  Before tightening the timing belt, turn the nut on the tensioning device using the turning tool -T20197- about five times in both directions - arrows -. –  Tighten the timing belt by turning the tensioning device nut using the turning tool -T20197- in the direction of -arrow A- as far as it will go. –  Then slacken the timing belt until the break -1- is facing the indicator -2-. –  Tighten the fastening bolt -3- on the tensioning device. –  Turn the crankshaft two complete turns in the direction of rotation of the engine until it reaches TDC again.   Note It is important that it turns non-stop for the last 45°. –  Check the tightness of the timing belt again. The indicator and the break must be facing each other. –  Install lower and centre notched belt guards.   Note Place the bolts into the console support before positioning it.

–  Fit the console to the engine block and tighten the bolts -arrows-. –  Fit vibration damper / pulley → Chapter.

–  Position the ribbed belt tension damper and tighten the bolts -arrows-.

–  Fit the driven train mounting, engine side, and tighten the bolts -arrows-.   Note Tightening torques of the mechanical unit engine mountings → Chapter. –  Fit the Poly-V belt → Chapter. Continue the fitting, following the reverse order of the removal process. Torque values
