AIR CONDITIONING
- General Information
Compressor - The prime purpose of the compressor IS to
r:ompress the low pressure refrigerant vapor from the evapo-
rator rnto a high pressure, high temperature vapti The 6
cylinder DR6148_compressor_rs used on all vehicles in this
.~
Service Manual. .~ ~~
Magnetic Clutch - are mounted on the compressor provrdrng
d convenrent way to drrve and disengage it in accordance to the
coolrng needs.
Condenser - IS located In tront of the radiator. Its function
IS
to
cool the hot, high pressure retngerant gas causing it to
condense into high pressure_lrqurd refrigerant.
Receiver Drier - is used to remove any traces of moisture from
the refrigerant system. This component rncorporates the sight
glass.
Sight Glass - at the top ot the recerver drier 1; provrded as a
diagnostic tool to observe refrigerant flow and indjcate re-
frigerant level.
Dual Pressure Switch - prevents damage to the compressor
In case ot system loss and over of refngeran7 charge.
Fusible Plug - is 1ocate.d on the receiver drier. Its function IS to
prevent damage to the air-condrtroning system In the event that
ekcessrve pressures develops due to condenser air flow being
restricted by forexample, leaves, newspaper, and overcharge
of refrigerant, or air In the system.
Expansion Valve - The expansion valve
IS
used tor all
applicatrons. Its functron
IS
I to meter refrigerant into the

Evaporator Coil - is located rn the evaporator and Its tunction
is to cool, and dehumidify the arr before it enters the vehicles.
Freeze Control - A thermistor is Installed at the heater srde
evaporator.

water -on the fa_ce of the esporator coil fro-m freezing and
restricting air flow.
Service Valves - at the compressor and the discharge. The
