10. INSTALL GLASS
HINT:
Confirm that the dam is attached the body panel as shown in
the illustration.
(a) Position the glass so that the reference marks are lined
up, and press in gently along the rim.
(b) Using a spatula, apply adhesive on the glass rim.
(c) Use a spatula to remove any excess or protruding adhe-
sive.
(d) Fasten glass securely until the adhesive sets.
11. INSPECT FOR LEAKS AND REPAIR
(a) Perform a leak test after the hardening time has elapsed.
(b) Seal any leaks with sealant.
Part No. 08833-00030 or equivalent.
12. INSTALL WINDSHIELD MOULDING
(a) Using a knife, cut off the adhesive around the moulding
installation area.
(b) Apply adhesive at moulding installation area.
(c) Place the moulding onto the body and tap it by hand.
13. INSTALL COWL LOUVER AND WIPER ARMS (See
page BO-26)
14. INSTALL INNER REAR VIEW MIRROR

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 RECURC is 30 - 35 °C (86 - 95 °F).
Engine running at 1,500 rpm.
Blower speed control switch set at high.
Temperature control set at max. cool.
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

3. INSPECT IDLE-UP SPEED
(a) Warm up engine.
(b) Inspect idle-up speed when the these conditions are es-
tablished.
Test conditions:
Blower speed control switch HI
Electrical lood OFF
A/C switch ON
Put gear shift in neutral
Standard idle-up speed: 800 - 900 rpm
If idle speed is not as specified, check the IAC valve and air in-
take system.
4. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Perform in these conditions:
Stop engine.
Secure good ventilation (If the gas leak detector
may not react to volatile gases which are not refrig-
erant, such as evaporated gasoline and exhaust
gas.)
Repeat the test 2 or 3 times.
Make sure that there is some refrigerant remaining
in the refrigeration system.
When compressor is OFF: approx. 392 - 588 kPa
(4 - 6 kgf/ cm
2, 57 - 85 psi)
(b) Bring the gas leak detector close to the drain hose before
performing the test.
HINT:
After the blower motor has stopped, leave the cooling unit
for more than 15 minutes.
Expose the gas leak detector sensor under the drain
hose.
When bring the gas leak detector close to the drain hose,
make sure that the gas leak detector does not react to the
volatile gases.
If such reaction is unavoidable, the vehicle must be lifted up.
(c) If gas leak is not detected on the drain hose, remove the
power transistor from the cooling unit. Then insert the gas
leak detector sensor into the unit and perform the test.
(d) Disconnect the connector and leave the pressure switch
for approx. 20 minutes. Then bring the gas leak detector
close to the pressure switch and perform the test.
(e) Bring the gas leak detector close to the refrigerant lines
and perform the test.
