Use only NEW, moisture-free refrigerant oil in A/C systems.
Refrigerant oil is highly refined with a very low moisture content.
Oil container must be tightly closed when not in use, or moisture from
air will be absorbed into refrigerant oil.
Refrigerant R-134a systems use Polyalkylene Glycol (PAG)
refrigerant oil. Using a mineral oil based lubricant with R-134a
systems will result in A/C compressor failure due to lack of proper
lubrication.
All compressors have different lubrication requirements and
use different Polyalkylene Glycol (PAG) refrigerant oils. Use only the\
specified PAG refrigerant oil for the appropriate system and A/C
compressor. Always check the underhood A/C specification label or A/C
compressor label before adding refrigerant oil to A/C
compressor/system. See listing of refrigerant oils currently available
from the vehicle manufacturers.
NOTE: PAG oil absorbs moisture very rapidly, 2.3-5.6 percent by
weight as compared to a mineral oil absorption rate of .005
percent by weight.
CHRYSLER CORP., JEEP & EAGLE
Use ND-8 PAG oil, SUN PAG 56 oil, SP-10 PAG oil, or SP-20 PAG
oil.
FORD MOTOR CO.
Use YN-12B or YN-12C PAG Refrigerant Oil (specification WSH-
M1C231-B) or SP-20 PAG Oil (specification WST-M1C231-B2).
GENERAL MOTORS
On all models except Saturn, use PAG Refrigerant Oil (Part
No. 12345923). On Saturn, use Saturn PAG refrigerant oil.
SERVICING PRECAUTIONS
DISCHARGING SYSTEM
Discharge A/C system, using approved refrigerant
recovery/recycling equipment before loosening any fittings. Follow
refrigerant recovery/recycling equipment manufacturer's instructions.
DISCONNECTING LINES & FITTINGS
After system is discharged, carefully clean area around all
fittings to be opened. Always use 2 wrenches when loosening or
tightening fittings. Some refrigerant lines are connected with a
spring-lock coupling. Special tools may be required to disconnect
lines. To prevent dirt and moisture from entering system, cap all
openings as soon as lines are removed. DO NOT remove service valve
caps until ready to connect lines and fittings.
NOTE: All R-134a based systems use 1/2-16 ACME threaded fittings.
Ensure all replacement parts match the connections of the
system being worked on.
CONNECTING LINES & FITTINGS
Always use new a gasket or "O" rings when connecting lines or

MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection communication standards
