Fig. 4: Determining Caster Angle

TOE-IN ADJUSTMENT
Toe-in is the width measured at the rear of the tires subtracted by the width measured at the front of the tires at about spindle height. A
positive figure would indicate toe-in and a negative figure would indicate toe-out. If the distance between the front and rear of the tires is the
same, toe measurement would be zero. To adjust:
1) Measure toe-in with front wheels in straight ahead position and steering wheel centered. To adjust toe-in, loosen clamps and turn adjusting
sleeve or adjustable end on right and left tie rods. See Fig. 2
and Fig. 5 .
2) Turn equally and in opposite directions to maintain steering wheel in centered position. Face of tie rod end must be parallel with machined
surface of steering rod end to prevent binding.
3) When tightening clamps, make certain that clamp bolts are positioned so there will be no interference with other parts throughout the entire
travel of linkage.

Fig. 5: Wheel Toe
-In (Dimension A Less Dimension B)
TOE-OUT ON TURNS
1. Toe-out on turns (turning radius) is a check for bent or damaged parts, and not a service adjustment. With caster, camber, and toe-in
properly adjusted, check toe-out with weight of vehicle on wheels.
2. Use a full floating turntable under each wheel, repeating test with each wheel positioned for right and left turns. Incorrect toe-out
generally indicates a bent steering arm. Replace arm, if necessary, and recheck wheel alignment.

1991-92 AIR CONDIT IONING & HEAT ING
A/C System General Servicing
HANDLING/SAFETY PRECAUTIONS
1. Always work in a well-ventilated, clean area. Refrigerant R-134a is colorless and is invisible as a gas. Refrigerant (R-12 or R-134a) is
heavier than oxygen and will displace oxygen in a confined area. Avoid breathing refrigerant vapors. Exposure may irritate eyes, nose
and throat.
2. The system's high pressure can cause severe injury to eyes and skin if a hose were to burst. Always wear eye protection when working
around A/C system and refrigerant. If necessary, wear rubber gloves or other protective clothing.
3. Refrigerant evaporates quickly when exposed to atmosphere, freezing anything it contacts. If liquid refrigerant contacts eyes or skin, DO
NOT rub eyes or skin. Immediately flush affected area with cool water for 15 minutes and consult a doctor or hospital.
4. Never use R-134a in combination with compressed air for leak testing. Pressurized R-134a in the presence of oxygen (air concentrations
greater than 60% by volume) may form a combustible mixture. DO NOT introduce compressed air into R-134a containers (full or
empty), A/C system components or service equipment.
5. DO NOT expose A/C system components to high temperatures, steam cleaning for example, as excessive heat will cause
refrigerant/system pressure to increase. Never expose refrigerant directly to open flame. If refrigerant needs to be warmed, place bottom
of refrigerant tank in warm water. Water temperature MUST NOT exceed 125°F (52°C).
6. Use care when handling refrigerant containers. DO NOT drop, strike, puncture or incinerate containers. Use Department Of
Transportation (DOT) approved, DOT 4BW or DOT 4BA, refrigerant containers.
7. Never overfill refrigerant containers. The safe filling level of a refrigerant container MUST NOT exceed 60% of the container's gross
weight rating. Store refrigerant containers at temperature less than 125°F (52°C).
8. R-12 refrigerant (Freon) will be sold and stored in White containers, while R-134a refrigerant will be sold and stored in 30- or 50-
pound Light Blue containers.
9. R-12 and R-134a refrigerants must never be mixed, as their desiccants and lubricants are not compatible. If the refrigerants are mixed,
system cross-contamination or A/C system component failure may occur. Always use separate servicing and refrigerant
recovery/recycling equipment.
10. Follow equipment manufacturer instructions of all service equipment to be used. The Material Safety Data Sheet (MSDS), provided by
refrigerant manufacturer/suppliers, contains valuable information regarding the safe handling of R-12 or R-134a refrigerants.
IDENTIFYING R-134A SYSTEMS & COMPONENTS
To prevent refrigerant cross-contamination, use following methods to identify R-134a based systems and components.
Fittings & "O" Rings
All R-134a based A/C systems use 1/2" - 16 ACME threaded fittings (identifiable by square threads) and quick-connect service couplings. See
Fig. 1
. Besides the use of these fittings, most manufacturers will use Green colored "O" rings in R-134a systems. CAUT ION: When discharging air conditioning system , use only approved refrigerant recovery/recycling
equipm ent. Make every attem pt to avoid discharging refrigerant into the atm osphere.

compressor label before adding refrigerant oil to A/C compressor/system. See Fig. 2 . The following R-134a refrigerant oils are currently
available.

compressor.
Saab

SERVICE EQUIPMENT
Because R-134a is not interchangeable with R-12, separate sets of hoses, manifold gauge set and recovery/recycling equipment are required to
service vehicles. This is necessary to avoid cross-contaminating and damaging system.
All equipment used to service systems using R-134a must meet SAE standard J1991. The service hoses on the manifold gauge set must have
manual (turn wheel) or automatic back-flow valves at the service port connector ends. This will prevent refrigerant from being released into
the atmosphere.
For identification purposes, R-134a service hoses must have a Black stripe along its length and be clearly labeled SAE J2196/R-134a. The low
pressure test hose is Blue with a Black stripe. The high pressure test hose is Red with a Black stripe, and the center test hose is Yellow with a
Black stripe.
R-134a manifold gauge sets can be identified by one or all of the following.
Labeled FOR USE WITH R-134a on set
Labeled HFC-134 or R-134a on gauge face
Light Blue color on gauge face
In addition, pressure/temperature scales on R-134a gauge sets are different from R-12 manifold gauge sets.
SYSTEM SERVICE VALVES
SCHRADER-TYPE VALVES
Schrader valve is similar in construction and operation to a tire valve. When a test gauge hose with built-in valve core depressor is attached,
Schrader stem is pushed inward to the open position and allows system pressure to reach gauge.
If test hose does not have a built-in core depressor, an adapter must be used. Never attach hose or adapter to Schrader valve unless it is first
connected to manifold gauge set.
Refrigerant R-12 Schrader-type valve cores have TV5 thread size. Refrigerant R-134a Schrader-type valve cores use M6 (Metric) threads. R-
134a valve cores can be easily identified by use of "O" rings and external spring. See Fig. 1
.
SERVICE VALVE LOCATIONS
SERVICE VALVE LOCATIONS NOTE:Synthetic/PAG oils absorb m oisture very rapidly, 2.3-5.6% by weight, as com pared to a m ineral oil
absorption rate of .005% by weight.
NOTE:Refrigerant R-12 service hoses will ONLY be labeled SAE J2196.
NOTE:Although sim ilar in construction and operation to a tire valve, NEVER replace a Schrader-type valve
with a tire valve.
