TOYOTA SUPRA 1997 Service Repair Manual

25 SUPRAÐ NEW FEATURES
NEW FEATURES
 EXTERIOR DESIGN
1. Headlights, Turn Signal Light and Front Bumper
Multi±reflector type headlights, which contain a multiple paraboloid reflector, have been adopted for the
high±beam headlights. Accordingly, the lens cut in headlights has been significantly decreased to improve the
appearance.
The shape of the turn signal light lenses has been matched to the curvature of the bumper in order to make them
appear integrated with the bumper. In addition, clear lenses are used, and the parking lights gave been changed from
those enclosed in the headlights to those enclosed in the turn signal lights.
A bar has been added to the air intake opening in the center of the front bumper.
2. Rear Combination Light
The lens cut of the rear combination lights has been changed from the vertical cut to the lateral cut. In addition, the
rear combination lights have adopted multi±reflectors. As a result of these changes a light design has been achieved
to give a sensor for translucency and depth.

type seats without changing their basic design.
4. 2JZ±GTE Engine
An aluminum radiator core is adopted for weight reduction.
5. Differential

A differential gear ratio has been changed on he 2JZ±GE engine model.

A helical gear type torque±sensing LSD is available as an option on the 2JZ±GE engine model and 2JZ±GTE engine
with automatic transmission model.
6. Drive Shaft
An outboard joint of drive shaft has been changed from cross±groove type CVJ (Constant±Velocity Joint) to Rzeppa
type CVJ on the 2JZ±GE engine model.
7. Brakes

A master cylinder diameter has been changed on the 2JZ±GTE engine model.

An ABS has been changed to the 2±position solenoid valve type actuator.

23 SUPRAÐ NEW FEATURES
8. Suspension
Various areas of the suspension system have been revised to realize excellent riding comfort, in addition, this provides
excellent stability, and controllability.
9. Body

Reinforcements and gussets have been newly added to the bottom of the front and center pillars.

An energy absorbing pads are provided at the door trim.

Sound absorbing material is newly provided in the front pillar and in the quarter to reduce road noise.

The material of sound absorbing material used in the trim and garnish has been changed.
10.Light
An illuminated entry system has been discontinued.
11. SRS Airbag
As in the '95 Avalon, a 1±sensor type airbag system has been adopted.
12.Cruise Control System

ON-VEHICLE INSPECTION
1. INSPECT REFRIGERANT VOLUME
Observe the sight glass on the liquid tube.
Test conditions:
Running engine at 1,500 rpm
Blower speed control switch at ºHIº position
A/C switch ON
Temperature control dial at ºCOOLº position
Fully open the doors
ItemSymptomAmount of refrigerantRemedy
1Bubbles present in sight glassInsufficient*
(1) Check for gas leakage with gas leak de-
tector and repair if necessary
(2) Add refrigerant until bubbles disappear
2No bubbles present in sight glassNone, sufficient or too muchRefer item 3 and 4
3No temperature difference between com-
pressor inlet and outletEmpty or nearly empty
(1) Check for gas leakage with gas leak de-
tector and repair if necessary
(2) Add refrigerant until bubbles disappear
4Temperature between compressor inlet and
outlet is noticeably differentCorrect or too muchRefer to items 5 and 6
5Immediately after air conditioning is turned
off, refrigerant in sight glass stays clearToo much
(1) Discharge refrigerant
(2) Evacuate air and charge proper amount
of purified refrigerant
6When air conditioning is turned off, refriger-
ant foams and then stays clearCorrect-
*: Bubbles in the sight glass with ambient temperatures higher than usual can be considered normal if cooling
is sufficient.

2. INSPECT REFRIGERANT PRESSURE WITH MAN-
IFOLD GAUGE SET
This is a method in which the trouble is located by using a man-
ifold gauge set. Read the manifold gauge pressure when these
conditions are established.
Test conditions:
Temperature at the air inlet with the switch set
at RECIRC is 30 - 35 °C (86 - 95 °F)
Engine running at 1500 rpm
Blower speed control switch at ºHIº position
Temperature control dial on ºCOOLº position
HINT:
It should be noted that the gauge indications may vary slightly
due to ambient temperature conditions.
(1) Normally functioning refrigeration system.
Gauge reading:
Low pressure side:
0.15 - 0.25 MPa (1.5 - 2.5 kgf/cm
2)
High pressure side:
1.37 - 1.57 MPa (14 - 16 kgf/cm

During operation, pressure on low
pressure side sometimes become
a vacuum and sometime normal
Moisture entered in refrigeration
system freezes at expansion valve
orifice and temporarily stops cycle,
by normal state is restored after a
time when the ice melts Drier oversaturated state
 Moisture in refrigeration system

ant(1) Replace receiver
(2) Remove moisture in cycle
through repeatedly evacuating air
(3) Charge proper amount of new
refrigerant
(3) Insufficient cooling
Symptom seen in

 Pressure low on both low and
high pressure sides
 Bubbles seen in sight glass con-
tinuously
 Insufficient cooling performance
Gas leakage at some place in re-
frigeration systemInsufficient refrigerant in sys-
tem
 Refrigerant leaking
(1) Check for gas leakage with gas
leak detector and repair if neces-
sary
(2) Charge proper amount of re-
frigerant
(3) If indicated pressure value is
near 0 when connected to gauge,
create the vacuum after inspecting
and repairing the location of the
leak
