Cleaning to be carried out just prior to refitting the cylinder head
WARNING: Clean the contact faces with the approved CITROËN cleaning product.
Do not use abrasives or cutting tools on the contact faces.
The contact faces must not bear any traces of impact or scratching.
Insert a tap in the threads of the holes in the cylinder block receiving the cylinder head bolts.
Brush the threads of the cylinder head bolts.
Oil the threads and under the heads of the bolts, using MOLYKOTE G RAPID PLUS.

CHECKING AND SETTING THE VALVE TIMING
Engine: DT17BTED4
Peg the camshafts, using tools [3]at "h"and "g".
Slacken:
- The 3 screws (15)of the camshaft pulley (23).
- The 3 screws (17)of the camshaft pulley (18).
- The screw (21)of the tensioner roller (20).
Remove the timing belt (22).
Checks.
IMPERATIVE: Just before refitting, carry out the checks below.
Check that the rollers (16), (20)and (19)and the coolant pump (14)can turn freely (without play
and without any tight spot).
Check that there are no signs of oil leaks (from the crankshaft and camshaft seals).
Check that there are no signs of coolant leaks (from the coolant pump).
Replace components that are faulty (if necessary).
Refitting.
Reposition the timimg belt on the crankshaft pinion (24).
Hold the timing belt (22)in position, using tool [4].
Tighten the screws (15)and (17)by hand.
Turn the camshaft pulleys (23)and (18)clockwise, to place them at the end of slots.
