Tensioning the V-belt
The tension of these compressor V-belt is
checked every 20.000 km. If the airconditio-
ner is used frequently the V-belt tension
should also be checked between the ser-
vice intervals.
The three mounting bolts (A) must be
loosened for tensioning the V-belt. Correct
the V-belt tension with tensioning nut (B)
and tighten the mounting bolts (A). The V-
belt is correctly tensioned when it can be
depressed approx. 5 mm using thumb pres-
sure, between both V-belt pulleys.
Checking cooling medium level
Due to the fact that the system loses cool-
ant it is necessary to check the coolant level
at the reservoir at least once a year.
Should air bubbles be visible at the inspec-
tion glass of the reservoir (arrow) for an
extended period, with the air conditioner
switched on, this indicates a lack of coolant.
Air bubbles will be normally visible for a short
time.
If necessary have the system re-filled in an
appropriately equipped service workshop.
