  Note!
t  Always replace the cylinderhead bolts.
t  In the event of reparation, carefully eliminate the remains of the gasket from the cylinderhead and from the engine block. Do not scratch the surfaces. If using sandpaper, the grain must be no less than 100.
t  Carefully eliminate abrasive particles.
t  Do not remove the new cylinderhead gasket from its packaging until just before fitting.
t  Handle the gasket with extreme care. Damage to the silicone coating or grooved area may cause leaks.
–  Before fitting the cylinderhead, set the crankshaft at TDC.
–  Turn the crankshaft against engine rotation until the pistons are all roughly evenly below TDC.
–  Position the cylinderhead gasket.
–  Position the cylinderhead, fit the 8 cylinderhead bolts and hand-tighten them.
   
–  Tighten the cylinderhead in four stages in the tightening order shown below:
1. Pretightening with torque spanner:
Stage I = 40 Nm
Stage II = 60 Nm
2. Retightening with rigid spanner:
Stage III = 1/4 turn (90°)
Stage IV = 1/4 turn (90°)
  Note!
It is not necessary to retighten the cylinderhead bolts after reparations.
  N15-0290
–  The retightening of the bolts with rigid spanner can be measured with the protractor -T20030-.
–  After tightening the cylinderhead, turn the camshaft pinion so that the cams of cylinder 1 point upwards uniformly. Before fitting the toothed belt, turn the crankshaft in the direction of engine rotation until TDC.
–  After installing the cylinderhead drain the fuel with vacuum pump -SAT 1390- with purge tank -SAT 1390/1- on the tandem pump → Chapter; Tandem pump: removing and installing.
–  Road test the vehicle and consult the fault memory: → Vehicle diagnosis, testing and information system VAS 5051
