Remove the tool [5] .

Remove the pulley driving the accessories using the tool [10] .

Loosen the exhaust line from the turbo .

IMPERATIVE : uncouple the exhaust line to avoid destroying the hose; this cannot withstand the torsion, traction or bending stresses caused by the removal of one of the power train supports .

Remove :

• the fasteners (3) - (5)
• the lower torque reaction link (4)
• the fixings for the inlet air duct
• disconnect and move aside the priming cone

Support the engine with tool [7] - [8] .

Protect the radiator honeycomb with strong cardboard cut to the dimensions of the radiator .

Remove :

• the priming cone (9) bracket
• the 3 timing housings (6)
• the bolts (7)
• the right-hand engine mounting (8)

Turn the crankshaft with the tool [6] .

Peg :

• the engine flywheel using tool [2]
• the camshaft pulley

Unlock the nut from the tensioner roller (11) .

Retighten the fastener in the maximum slack position .

Remove the timing belt .

3 - REFITTING

IMPERATIVE : check that the rollers (11) - (12) as well as the coolant pump (8) turn freely (no play or hard spots) ; also check that these rollers are not noisy and/or do not show traces of grease .

NOTE : in the event of replacement ; tighten the bolt (12) to 4.3 da.Nm .

Slacken the bolts (14) .

Check that the pulley (15) rotates freely on its hub .

Tighten the bolts (14) by hand .

Turn the pulley (15) clockwise to the limit at the end of the slots .

Fit the timing belt, fully taut, in the following order :

• crankshaft ; immobilise the belt using the tool [4]
• roller tensioner (12)

Lay the timing belt on the pulley (16) .

Slightly turn the camshaft pinion in the opposite direction to the rotation of the engine in order to engage the belt on the pinion .

WARNING : the angular movement (α) of the pulley in relation to the belt must not be more than one tooth space .

Engage the belt on the roller tensioner (12) and on the coolant pump gear (13) .

Place the tensioner roller (11) in contact with the belt .

Pre-tighten the tensioner roller securing bolt (11) to 0.1 daN.m .

Remove the tool [4] .

4 - PRE-TENSIONING AND FITTING THE TIMING BELT

Fit the tool [1] .

NOTE : check that the tool is not touching anything in the near vicinity .

Turn the roller tensioner (11) anti-clockwise, using tool [9] .

Display 98 ± 2 SEEM units .

Tighten the bolt (11) to 2.3 da.Nm. without altering the position of the roller .

Remove the tool [1] .

IMPERATIVE : by removing a bolt (14) on the pulley (15), ensure that these bolts are not at the limit of the slot ; if this is the case, repeat the timing belt fitting operation .

Tighten the bolts (14) to 2 daN.m .

Remove the setting pins [3] - [2] .

Turn the engine over 8 times in the normal direction of rotation .

IMPERATIVE : never turn the crankshaft in the reverse direction .

5 - FITTING AND TENSIONING THE TIMING BELT

Refit the rods [2] -[3] .

Slacken the bolts (14) .

Tighten the bolts (14) by hand .

Slacken the bolts (14) by 1/6 turn .

Slacken the bolt (17) .

Place the tool [1] on the span (A) .

Turn the roller tensioner anti-clockwise, using tool [9] .

Display 54 ± 2 SEEM units .

Tighten the bolt (17) to 2.3 da.Nm. without altering the position of the roller .

Tighten the bolts (14) to 2 daN.m .

Remove the tool [1] to release the internal forces .

Refit the tool [1] .

The tension value should be between 51 and 57 SEEM units .

IMPERATIVE : if the value read is outside the tolerance : slacken the belt and repeat the operation .

Remove :

• the equipment [1]
• the pegs [2] - [3]

6 - CHECKING THE VALVE TIMING

Turn the crankshaft 2 revolutions in the direction of running without turning in the reverse direction .

Fit the rod [2] .

IMPERATIVE : visually check that the offset between the camshaft hub hole and the corresponding setting hole does not exceed 1 mm .

Remove the rod [2] .

Fit :

• the bottom timing cover
• the timing covers
• the engine mounting
• the bolts (14) ; 6.1 da.Nm
• the bolts ; 2 da.Nm
• the priming cone bracket

Refit the tool [5] .

Refit the torque reaction link (4) .

Tighten :

• the bolt (3) to 4.5 da.Nm
• the bolt (5) to 5 da.Nm

Refit the ancillaries drive pulley .

Clean the threads of the bolt of the pulley in the crankshaft by using a M16 X 150 tap .

Cleanthe thread of the bolt .

Tightening :

• pre-tighten to 4 danm+ LOCTITE FRENETANCH
• complete the tightening by rotating 51 degrees using a FACOM 360° type tool

Check the tightening :

• apply a torque of 19.5 danm using a torque wrench
• the wrench must trip before the screw rotates

If this is not the case :

• slacken the bolt
• recommence the entire tightening procedure

fit the ancillary drive belt .

Remove the tool [5] .

IMPERATIVE : always replace the exhaust clips .

Tighten the wheel bolts to 9 da.Nm .

Refit the various components in the reverse order to removal .

Initialise the various ECUs .
