4. Anti-rust treatment after installation

(A) body sealer application

(A) body sealer application

Purpose: for water-proofing and anti-rust measures, always apply the body sealer to the body panel seams and hems of the doors, hood, etc.

Notice

: apply body sealer neatly to parts that require a high quality appearance.

(B) undercort application

(B) undercort application

Purpose:

to prevent corrosion and protect the body from gravel, always apply a sufficient undercoating to the areas indicated.

(C) vehicle body anti-rust agent

(C) vehicle body anti-rust agent application

Purpose:

the purpose is to protect areas from rust which are difficult to paint such as the backside of the box-shaped cross section frame parts.

Method

: apply anti-rust agent through the service holes and/or installation holes of the parts.

5. Headlight bracket repair

Hint:

  • if the installation area of the headlight assembly is damaged, use the supply retainer for low-cost repair.
  • Ensure that the headlight assembly is not damaged.

    Inspection procedure
    Hint: read freeze frame data using the hand-held tester or the obd ii scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the ...
