REFITTING
I - REFITTING PREPARATION OPERATION
aparts always to be replaced: coolant tempera-
ture sensor seal.
aUse SURFACE CLEANER (see Vehicle: Parts
and consumables for the repair) (04B, Consuma-
bles - Products) to clean and degrease:
-the seal housing in the water chamber,
-the seal mating face of the coolant temperature
sensor if reused.
II - REFITTING OPERATION
aRefit:
-the coolant temperature sensor fitted with a new
seal,
-the coolant temperature sensor clip.
aConnect the coolant temperature sensor connector. IMPORTANT
The circuits are designed to be pressurised, so be
careful at high temperatures (risk of serious burns).
Do not remove the cap from the expansion bottle
while the engine is hot.
Take care when carrying out a repair under the bon-
net, as the radiator fan(s) may start to operate with-
out warning.
Do not open the bleed screw(s) with the engine run-
ning.
WARNING
Before the operation, protect the electrical accesso-
ries to prevent any risk of shor t circuiting and pro-
tect the belts to avoid damaging them.
WARNING
The coolant helps to keep the engine running prop-
erly (heat exchange).
The system does not operate using pure water.
