No cooling action;
Engine may overheat.
Suction line is very hot.Condenser is often
found not functioning
well.Check condenser
cooling fan.
Check condenser for
dirt accumulation.
Check engine cooling

2 MaskingMask specified part (black base) with masking tape. Use masking tape for PP (e.g., Nichiban No.
533, etc.).
3Degreasing, clean-
ingClean all parts to be painted with white gasoline, normal alcohol, etc. to remove dirt, oil, fat, etc.
4 Primer paint First, apply one coat of primer to all parts to be painted, using air gun. Use primer (clear).
5 DryingDry at normal temperature [10 to 15 min. at 20°C (68°F)].
In half-dried condition, PP primer paint is dissolved by solvent, e.g. thinner, etc.
Therefore, if dust or dirt must be removed, use ordinary alcohol, etc.
6 Top coat paint (I)Solid color Metallic color
Use section (block) paint for top coat.

Paint in use (for each color):
Solid paint
Hardener PB
Thinner T-301

Mixing ratio:
Main agent vs. hardener = 4:1

Viscosity: 10—13 sec/20°C (68°F)

Film thickness: 35—45µ

Spraying pressure: 245—343 kPa
(2.5—3.5 kg/cm
2,36—50 psi)Use section (block) paint for top coat.

Paint in use (for each color):
Metallic paint
Hardener PB
Thinner T-306

Mixing ratio:
Main agent vs. hardener = 10:1

Viscosity: 10—13 sec/20°C (68°F)

Film thickness: 15—20µ

Spraying pressure: 245—343 kPa
(2.5—3.5 kg/cm2,36—50 psi)
7 Drying Not required.Dry at normal temperature [10 min. or more at
20°C (68°F)].
In half-dried condition, avoid dust, dirt.
8 Top coat paint (II) Not required.Apply a clear coat to parts with top coat paint (I),
three times, at 5—7 minutes intervals.

Paint in use:
Metallic paint
Hardener PB
Thinner T-301

Mixing ratio: Clear vs. hardener = 6:1

Viscosity: 14—16 sec/20°C (68°F)

Film thickness: 25—30µ

Spraying pressure: 245—343 kPa
(2.5—3.5 kg/cm
2,36—50 psi)
9 Drying60°C (140°F), 60 min. or 80°C (176°F), 30 min.
If higher than 80°C (176°F), PP may be deformed. Keep maximum temperature of 80°C (176°F).

make sure ignition switch is OFF.
2. Inspection and Replacement
Standards
1. VEHICLES WHICH BECOME INVOLVED IN A
COLLISION
If the vehicle equipped with an SRS airbag system is
damaged in a collision, the airbag system parts must
be checked and replaced in accordance with the fol-
lowing standards:
After faulty parts are replaced, the warning light opera-
tion must be checked.
When the ignition switch is turned ON, it lights up
for 8 seconds and then it goes out for at least 30 sec-
onds.
The trouble code stored in memory must be erased
after the check.
2. AIRBAG MODULE (DRIVER AND PASSENGER)
Inspection standard:
The vehicle damaged in a collision (regardless of
whether or not airbag is deployed).
The designated trouble code is output during self-diag-
nosis. (Refer to“Diagnostics”Section.)
Replacement standard:
Airbag is deployed.
The pad surface is scratched or cracked.
Harness and/or connector is deformed or cracked, their
circuits are broken, lead wire is exposed, etc.
Mounting bracket is cracked or deformed.
The module surface is fouled with foreign matter.
(grease, oil, water, cleaning solvent, etc.)
Airbag module dropped to the floor/ground.
Airbag module determined as faulty during self-diagno-
sis.
