Installing toothed belt, tensioning (setting timing)
  Note
t  Also when carrying out repairs which necessitate taking the toothed belt only off the camshaft sprocket, it is then necessary to carry out the installation of the toothed belt as follows.
t  When rotating the camshaft, the crankshaft must not be positioned at TDC. Risk of damaging valves and piston crowns.
Condition
l  The pistons must not be positioned at top dead centre.
   
–  Bring the marking on the camshaft sprocket in line with the marking on the rear timing belt guard -arrows-.
–  Position crankshaft to TDC cylinder 1 → Chapter (except when engine removed).
–  Fit toothed belt onto toothed belt sprocket of crankshaft and coolant pump (pay attention to direction of running) → Chapter
  Note
  S13-0575
When engine removed, after this, install bottom toothed belt guard and vibration damper. Position crankshaft to TDC of cylinder 1 -arrows-.
–  Fit timing belt onto tensioning pulley and onto camshaft sprocket.
Pay attention to installation position of semi-automatic tensioning pulley → Fig.
  S13-0572
–  Before tensioning the toothed belt, rotate the tensioning pulley at the eccentric with the two-hole nut turner -T10020- about 5 times in both directions as far as the stop.
–  Turn the semi-automatic tensioning pulley fully to the left with two-hole nut turner -T10020--in direction of arrow-.
–  Loosen tensioning pulley until the notch -1- and the pointer -2- are positioned opposite.
–  Tighten nut securing semi-automatic tensioning pulley to 25 Nm.
–  Turn crankshaft two turns further in the direction of running of the engine and again position on TDC for cylinder 1.
   When doing this, it is important that the last 45° (1/8 turn) are rotated without any interruption.
–  Once again inspect tension of toothed belt.
   Specified value: Pointer and notch are positioned opposite.
–  Install bottom and middle toothed belt guard.
  S13-0577
–  Install belt pulley with vibration damper. Tightening torque: 25 Nm
  Note
Before installing engine support, insert bolts into engine support.
–  Install engine support and engine mounts. Tightening torques:
t  Engine support to cylinder block: 45 Nm
t  Engine mount to engine support → Chap. 10-2
t  Engine mount to body → Chap. 10-2
–  Align component mounting engine → Chap. 10-2.
–  Remove supporting device -MP 9-200-.
–  Install top toothed belt guard.
–  Install tensioning device for V-ribbed belt. Tightening torque: 25 Nm.
–  Install the V-ribbed belt → Chapter 13-1.
–  Install coolant expansion reservoir.
–  Install the reservoir for the power-assisted steering.
–  Install noise insulation and engine cover
