Description
Outline
The air conditioner system delivers cooled air into the passenger compartment by circulating refrigerant through the sys-
tem as shown below.
CONDENSOR
This car uses HFC-134a {R-134a) refrigerant which does not contain chlorofluorocarbons Pay attention to the following
service items:
. Do not mix refrigerants CFC-I2 (R-l21 and HFC-134a (R-134a) They are not compatible'
. Use onty the recommended potyatkytenegtycol {PAG) refrigerant oil (ND-OIL 8: P/N 38899-PR7-A01) designed for the R-
134a compressor. Intermixing the recommended (PAG) refrigerant oil with any other refrigerant oil will result in com-
pressor tailure.

. Use a halogen gas leak detector designed for refrigerant R-134a'
. R-.12 and C-l34a refrigerant servicing equipment are not interchangeable. Only use a Recovery/Recyclins/Charging
System that is U.L.-listed and is certifLd to meet the requirements of sAE J2210 to service R-134a air conditioning sys-
rems.
. Always recover the refrigerant R-134a with an approved Recover/Recycling/Charging System before disconnecting any

A/C Service Tips and Precautions
The air conditioner system uses HFC-134a (R-134a) .efrigerant and polyalkyleneglycol (PAG) retrigerant oil (ND-OIL g: p/N
38899 - PR7 - A0l ), which are not compatible with CFC-12 \R-'12) refrigerant and mineral oil. Do not use R-12 refrigerant ormineral oil in this system, and do not attempt to use R-'12 servicing equipment; damage to the air conditioner system oryour servicing equipment will result.
only use service equipment that is u.L,-listed and is certified to meet the requirements of sAE J2210 to remove R-134afrom the air conditioner svstem.
CAUTION: Exposure lo air conditioner refrigorant and lubricanl vapor or mi3t cln irritato gyos, nose and throat. Avoidbreathing lhe air conditioner refrigerant and lubricant vapor or mist.
lf accidental system discharge occurs, ventilate work area befor€ resuming service.R-134a service equipment or vehicle air conditioner systems should not be pressure tested or leak tested with compressedair.
@ some mirtures of air and R-l3ifa have been 3hown to be combu3tible at slsvated prossuros and can relultin fire or explosion causing inlury or property damage. Never use complessod ai. to prgssure t€|st R-134a service equip-ment or vehicle air conditiongr systems.
Additional health and safety information may be obtained from the refrigerant and lubricant manufacturers.'1. Always disconnect the negative cable from the battery whenever replacing air conditioning pans.
2. Keep moisture and dust out of the system. When disconnecting any lines, plug or cap the fittings immediately; don'tremove the caps or plugs until just before you reconnect each line.
3. Before con necting a ny hose or line, apply a few drops of refrigerant oil (ND-OIL 8: P/N 38899 - PR7 - AO1) to the O-ring.4. When tightening or loosening a fitting, use a second wrench to support the matching fitting.5. When recovering the system, use a R-134a refrigerant Recovery/Recycling/Charging System; don't release refrigerantinto the atmosDhere.
6. Add refrigerant oil (ND-OlL 8: P/N 38899 - PR7 - A01) after replacing the following parts:
NOTE:
. To avoid contamination, do not return the oil to the container once dispensed, and never mix it with other refriqer-ant orls.
. lmmediately after using the oil, replace the cap on the container and seal ittoavoid moisture absorption,. Do not spill the refrigerant oil on the car; it may damage the paint; if the re{rigerant oil contacts the paint, wash itoff immediately.

Overhaul
L Pull out the Ay'C thermostat sensor from the evapo-rator fins.
2. Remove the self-tapping screws and clamps fromthe housing.
3. Carefully separate the housings and remove theevaporator.
4. lf necessary, remove the expansion valve.
NOTE: When loosening the expansion valve nuts.use a second wrench to hold the expansion valve orevaporator pipe. Otherwise, they can be damaged.
Assemble in the reverse order of disassembly, and:
. feplace the O-rings with new ones at each fitting,and apply a thin coat of refrigerant oil (ND-OIL 8:P/N 38899 - PR7 - A01) before installing them.NOTE: Be sure to use the right O-rings for HFC-134a {R-134a) to avoid leakage.. install the expansion valve capillary tube withthe capillary tube in contact with the suction linedi.ectly, and wrap it with tape.. reinstall the Ay'C thermostat sensor to its originallocation.
