AIR CONDITIONING

ADJUSTMENT

SYSTEM TEST

1. Place the vehicle in a ventilated, shaded area

free from excessive draught, with the doors and
windows open.

2. Check that the surface of the condenser is not

restricted with dirt, leaves, flies, etc. Do not
neglect to check the surface between the
condenser and the radiator. Clean as necessary.

3. Switch on the ignition and the air conditioner air

flow control. Check that the blower is operating
efficiently at low, medium and high speeds.
Switch off the blower and the ignition.

4. Check that the evaporator condensate drain

tubes are open and clear.

5. Check the tension of the compressor driving belt,

and adjust if necessary.

6. Inspect all connections for the presence of

refrigerant oil. If oil is evident, check for leaks,
and repair as necessary.

NOTE: The compressor oil is soluble in
Refrigerant R134a and is deposited when
the refrigerant evaporates from a leak.

7. Start the engine.
8. Set the temperature controls to cold and switch

the air conditioner blower control on and off
several times, checking that the magnetic clutch
on the compressor engages and releases each
time.

9. With the temperature control at maximum

cooling and the blower control at high speed,
warm up the engine and fast idle at 1000
rev/min. Check the sight glass for bubbles or
foam. The sight glass should be generally clear
after five minutes running, occasional bubbles
being acceptable. Continuous bubbles may
appear in a serviceable system on a cool day, or
if there is insufficient air flow over the condenser
at a high ambient temperature.

10. Repeat at 1800 rev/min.
11. Gradually increase the engine speed to the high

range, and check the sight glass at intervals.

12. Check for frosting on the service valves.
13. Check the high pressure hoses and connections

by hand for varying temperature. Low
temperature indicates a restriction or blockage at
that point.

14. Switch off the air conditioning blower and stop

the engine.

15. If the air conditioning equipment is still not

satisfactory, carry out a pressure test as
previously described in this section.
