Toyota Corolla (E140): Introductions

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.

(A) install upper headlight protector

(A) install upper headlight protector retainer

(1) cut off the part shaded in the illustration and smooth with sandpaper.

Notice

: after cutting off the part, place the upper headlight protector retainer against the bosses and gradually file away the old bracket if it interferes with the installation of the supply bracket.
