Checking

- Start engine.

- Set temperature control to maximum "cold".

- Press A/C button and select second blower

speed.

- Adjust air distribution to instrument panel

outlets.

- Insert thermometer into center instrument panel

outlet.

- Raise engine speed to approximately 1500

RPM.

Specified result

With normal humidity and outside (ambient)

temperature between 20 -25 C (68 -77 F),
system is sufficiently charged if air temperature
from center instrument panel vent drops below
10 C (50 F) within one minute.

For higher ambient temperatures and/or higher

humidity, specified air temperature from center
instrument panel vent can be slightly higher.

A/C refrigerant system,
checking for leaks

Use halogen leak detector, Hitec

HI400A-TEL or equivalent, to check
for refrigerant leaks, following the
leak detector manufacturer's
instructions.

Refrigerant gas dissipates very
quickly. To make the job easier,
avoid drafty or windy areas when
checking for leaks.

If the refrigerant system is
discharged (empty), re-charge the
system with approx. 100 g (3.5 oz) of
refrigerant in order to check for
leaks.

Notes:

R-134a refrigerant is packaged in different

containers. Some are used only for commercial
applications which are sold in cylinders using a
1/4" flare fitting. This does not connect to the
vehicle fittings and servicing equipment. Use
only R-134a which come in containers having
the correct type of service fitting.

Refrigerant oil attracts moisture from the air. It

is important that refrigerant oil containers are
closed tightly immediately after use.

Dispose of contaminated refrigerant oil

following laws governing hazardous waste
disposal. Do not combine any refrigerant oil
with any other old oils such as engine oil or
transmission fluid.
