REMOVAL
1) Remove A / C condenser assembly (1) from vehicle (Refer to
ªA / C CONDENSER ASSEMBLY REMOVALº in this section.).
2) Remove the condenser dryer cap from condenser.
3) Remove the filter (1) from the condenser (2).

INSTALLATION
Reverse removal sequence to install condenser dryer, according to
instruction manual with supply parts.
NOTE:

When replacing condenser dryer, add 40 cc of refrigerating
oil the same as compressor oil.

Do not remove the dryer from the plastic bag until just before
inserting it into the receiver.

Install the condenser dryer (1) with its double-layer portion
facing the bottom of the receiver.

COMPRESSOR ASSEMBLY
CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of A / C:
one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
For identification between these two types, refer to page 1B-2.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A / C installed in the vehicle being serviced.
Use of incorrect refrigerant or compressor oil will result in leakage of refrigerant, damage in parts or
other faulty condition.
PRECAUTION
When servicing the compressor, keep dirt or foreign material away from getting on or into the compressor parts
and system. Clean tools and a clean work area are important for proper service.
The compressor connection and the outside of the compressor should be cleaned before any ªOn-vehicleº repair
or before removal of the compressor. The parts must be kept clean at all times and any parts to be reassembled
should be cleaned with Trichloroethane, naphtha, kerosene or equivalent solvent and dried with dry air. Use only
lint free cloths to wipe parts.
The operations described are based on bench overhaul with compressor removed from the vehicle, except as
noted. They have been prepared in order of accessibility of the components.
When compressor is removed from the vehicle for servicing, the oil remaining in the compressor should be dis-
carded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair procedures re-
quire that the system be discharged of refrigerant.
INSPECTION
1) Install manifold gauge set (1) as shown in the figure.
2) Close Hi (4) and Lo (5) hand valves.
3) Run engine at fast idle.
4) Check compressor assembly for following items.
If any of the above checks indicated a defect, repair compressor
assembly.

High pressure gauge reading is not low and low pressure
gauge reading is not higher than normal.

TIRE DIAGNOSIS
IRREGULAR AND / OR PREMATURE WEAR
Irregular and premature wear has many possible causes. Some of
them are: incorrect inflation pressures, lack of tire rotation, driving
habits, improper alignment.
If the following conditions are noted, rotation is in order:
1. Front tire wear is different from rear.
2. Uneven wear exists across the tread of any tire.
3. Left front and right front tire wear is unequal.
4. Left rear and right rear tire wear is unequal.
5. There is cupping, flat spotting, etc.
A wheel alignment check is in order if the following conditions are
noted:
1. Left front and right front tire wear is unequal.
2. Wear is uneven across the tread of any front tire.
3. Front tire treads have scuffed appearance with ªfeatherº edges
on one side of tread ribs or blocks.
WEAR INDICATOR
The original equipment tires have built-in tread wear indicators to
show when tires need replacement. These indicators will appear as
12 mm (0.47 in.) wide bands when the tire tread depth becomes 1.6
mm (0.063 in.). When the indicators appear in 3 or more grooves
at 6 locations, tire replacement is recommended.
RADIAL TIRE WADDLE
Waddle is side to side movement at the front and / or rear of the ve-
hicle. It is caused by the steel belt not being straight within the tire.
It is most noticeable at low speed, 8 to 48 km / h (5 to 30 mph). It is
possible to road test a vehicle and tell on which end of the vehicle
the faulty tire is located. If the waddle tire is on the rear, the rear end
of the vehicle will shake from side to side or ªwaddleº. From the driv-
er's seat it feels as though someone is pushing on the side of the
vehicle. If the faulty tire is on the front, the waddle is more visual.
The front sheet metal appears to be moving back and forth and the
driver feels as though he is at the pivot point in the vehicle.
Waddle can be quickly diagnosed by using a Tire Problem Detector
(TPD) and following the equipment manufacturer's recommenda-
tions.
If a TPD is not available, the more time consuming method of sub-
stituting known good tire / wheel assemblies on the problem vehicle
can be used as follows:

NOTE:
All steering wheel and column fasteners are important parts in that they could affect the performance of
vital parts and systems, and / or could result in major repair expense. They must be replaced with one of
the same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality of substitute design. Torque values must be used as specified during reassemb-
ly to assure proper retention of this part.

GENERAL DESCRIPTION
This double tube type steering column has the following three important features in addition to the steering function:

The column is energy absorbing, designed to compress in a front-end collision.

The ignition switch and lock are mounted conveniently on this column.

With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified bolts be used as designated and that
they are tightened to the specified torque. When the column assembly is removed from the vehicle, special care
must be taken in handling it. Use of a steering wheel puller other than the one recommended in this manual or a
sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly could shear the
plastic shear pins which maintain column length and position.
