Observe the Safety instructions – Air conditioning system, see page 205.
The condenser Fig. 163-A of the air conditioning system is located on the
left-hand side of the vehicle behind the vehicle cab. Check the condenser
for contamination at regular intervals. Maintenance intervals according to
maintenance plan, see page 167.
Attention
If the condenser is clogged, the heat cannot be dissipated and
the coolant will heat up and expand. This increases the pres-
sure within the system. The system can burst, coolant can
escape, which would stop the air conditioning system from
A
being operational.
Clean the condenser as follows:
1. Place the vehicle on a level surface and secure it with the parking
brake.
2. Switch the engine off and pull out the ignition key. Allow the engine to
cool down.
3. Remove the left side cover Fig. 163-B, see page 183.
4. Blow out the condenser with compressed air towards the left-hand side
of the vehicle.
Observe the Safety instructions – Air conditioning system, see page 205.
Due to the design, vehicle air conditioning systems cannot be hermetically
sealed systems. Therefore, a (certain) creeping coolant loss is accepted
by the automotive industry. It can thus be assumed that each vehicle air
conditioning system becomes less efficient after a few years and must be
refilled.
Have the air conditioning system filled by an authorised workshop.
Maintenance intervals according to maintenance plan, see page 167.
