REPAIR
1. INSPECT WINDOW GLASS (ANTENNA WIRE)
NOTICE:
When cleaning the glass, use a soft, dry cloth, and wipe the
glass in the direction of the wire. Take care not to damage
the wires. Do not use detergents or glass cleaners with
abrasive ingredients. When measuring voltage, wind a
piece of tin foil around the top of the negative probe and
press the foil against the wire with your finger, as shown in
the illustration.
(a) Inspect the continuity at the center of each antenna wire
as shown in the illustration.
2. REPAIR WINDOW GLASS (ANTENNA WIRE)
(a) Clean the broken wire tips with a grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire to be
repaired.
(c) Throughly mix the repair agent (Dupont paste No. 4817).
(d) Using a fine tip brush, apply a small amount to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.

INSTALLATION

Temporarily install the new parts and measure each part of the new parts in accordance with the body dimension
diagram. (See the body dimension diagram)

Inspect the fitting of the related parts around the new parts before welding. This affects the appearance of the
finish.

After welding, apply the polyurethane foam to the corresponding parts.

After welding, apply body sealer and under-coating to the corresponding parts.

After applying the top coat layer, apply anti-rust agent to the inside of the necked section structural weld spots.
