Acura TL (1995-1998) body repair. Instruction - page 1

Preparation of Work

Description

• Most monocoque bodies are composed as a single unit by welding together pressed parts made of steel plates which come in

a variety of different shapes and sizes. Each part is responsible for displaying a certain strength and durability in order that it

may play its role in meeting the functions of the body as a whole.

Damage to the exterior of the body can be inspected visually, but where there has been an external impact, it is necessary to inspect

the extent of the damage. In some cases, the deformation has spread beyond the actual areas which were in the collision and so

this has to be inspected closely.

Checkpoints

• Accurate Inspection of Damaged Parts (Visual)

Seat Belts
Replace the seat belts if:

1. The belt material is cut, punctured, burned or in any way damaged.

2. The buckle or retractor does not work properly.
3. They were being worn at the time of a collision (check for damage at the seat belt anchor points).
4. Their condition is questionable.

Front Section:

1. Is there any bending, splitting, denting or other damage to the suspension and its related parts?

2. Is there any deformation of the front bulkhead or radiator core? Have any of the connected sections come apart?
3. Are there any creases or distortion in the front wheelhouse or side frame? Have any of the connected sections come apart?
4. Is there any bending or twisting of the whole front area?
5. Is there any deformation like creases, bulges, or dents in the front pillar, dashboard, floor, etc.?
6. Is there any vertical twisting or misaligned clearance in the door?
7. Is the windshield seal broken?
8. Is there any deformation in the vicinity of the top part of the roof panel's center pillar?
9. Is there any damage inside the automobile (is there any twisting of the dashboard, or anything irregular with the clearances

or sheet-mounting parts)?

10. Is there any damage to the steering wheel? Is there any deformation in the column and the column-mounted parts?

11. Is there any oil or water leakage and damage to the engine, transmission or brakes?
12. Is there any irregular noise in the gear changing operation, engine and transmission rotation?
13. Are there any traces of contact between the engine block and the dashboard lower panel?
14. Is there any damage to brake or fuel lines, or wire harnesses?

Rear Section:
1. Is there any twisting, bulging or denting of the rear floor and rear bolsters? Have any of the connected sections come apart?

2. Is there any irregular bulging or denting in the rear fender?
3. Is there any distortion in the rear inner panel? Is there any bending and denting in the vicinity of the rear pillar?
4. Is there any distortion or creasing is the rear wheelhouse and arch sections? Have any of the connected sections come apart?

5. Is there anything irregular in the rear glass and quarter glass seal clearance?
6. Is there any twisting or misalignment of the clearance of the trunk lid or tailgate opening section?
7. Is there any bending, splitting, denting or other damage to the suspension and its related parts?
8. Is there any deformation of the rear floor, rear floor cross member and damper base? Have any of the connected sections

come apart?

Preparation of Work

Correction of the Damaged Area

Set the frame corrector on the car body.

The side sill is flangeless to allow reshaping by pulling it out.

Use the horizontal pinch welds for anchoring the car.

UNDERBODY CLAMPS

1. Apply load to the damaged section and pull it out until

the section is almost restored to the original shape.

2. Check that the parts of the body they cover have been

more or less restored to their original shapes.

NOTE: Check the original position using the body
dimensional drawings (see

section 6

) and the position-

ing jigs (see page

1-7

).

3. Remove the parts that require replacement.

4. Decide whether to replace all the affected parts or

whether to cut the weld joint parts and replace them.

5. Cut off and separate the damaged parts.

NOTE: When cutting the parts off, take special care

that you do not damage adjacent parts on the automo-

bile.

Setting Condition of Replacement Parts Joint Sec-
tions:

• Make sure that you can perform straightening work

after welding.

• Make sure that the locations are not susceptible to

distortion caused by other parts.

• Make sure that there are few removable parts and

that the location allows safe welding.

• Make sure that the joints are short, and that paint

repair can be performed easily.

• Make sure the locations are such that the joints can

be finished in a way that does not affect the outward
appearance.

• Make sure that the locations do not hinder the

removing and attaching of parts.
NOTE: Bear in mind all of these conditions, and after
determining the joint locations, cut the joints for an
overlap of 20~30 mm (0.8~1.2 in).

6. Mold the related parts.

7. Set and tack weld the replacement parts.

NOTE: Temporarily mount the related parts and check

the clearance and level differences.

8. Weld the replacement parts.

Welding methods (see

section 2

).

NOTE: Use of the positioning jig is recommended.

CAUTION: Protect body parts with the heat-resistant
protective cover to prevent damage, when welding.

The paint film, which is designed to prevent corrosion
caused by moisture, is destroyed around the edges of the

locations which have been repaired by welding.

Therefore, in such places and especially in those areas

which are not visible, apply another coat of the paint,

referring to the anti-corrosion painting manual. This
operation is designed to maintain durability and quality
(see

section 7

).
