PAINT PAINT PROCEDURES
Replacement Panels
Service panels are supplied with a cathodic primer
coating as part of the panel protection, and in
compliance with the vehicle’s Corrosion Warranty
where applicable.DO NOT remove this primer
before paint refinishing. In the event of localised
surface damage or imperfections, ensure that the
minimum of primer is removed during rectification
work for effective repair.
Rectify damage by panel beating or straightening. To
remove corrosion or paint runs on outer surfaces,
abrade primer coat in the affected area as necessary
using the following procedure:
1. Clean the panel using a solvent wipe.
2. Treat exposed areas of metal with an etch
phosphate process.
3. Re-treat the affected area using either a
separate acid-etch primer and two-pack
surfacer, or an integrated etch primer/filler.
Bolted Panels
Before fitting bolt-on panels, ensure that all mating
and adjacent surfaces on the vehicle and replacement
panel are free from damage and distortion. Rectify if
necessary as described in this section, and apply
preformed strip sealer where specified.Welded Panels
1. Remove primer from the immediate vicinity of
new and existing panel flanges, cleaning to
bright metal finish.
2. On joints to be spot welded, apply weld-through
zinc rich primer to joint faces of both flanges.
Make spot welds while primer is still wet or
according to the manufacturer’s instructions.
3. Dress accessible weld seams.
4. Clean panel using solvent wipe.
5. Treat bare metal with an etch phosphate
process.
6. Re-treat repaired areas.
NOTE: It is not satisfactory to use
weld-through, zinc rich primers in
conjunction with MIG welding.
Sectioned Panels
When replacing part or sectioned panels, the basic
procedure is the same as for welded panels described
above, with the following variations:
1. Remove primer from both new and existing joint
faces, cleaning to a bright metal finish.
2. Where an overlap joint with the existing panel is
to be spot welded, apply weld-through, zinc rich
primer to both joint faces and spot weld while the
primer is still wet or according to the
manufacturer’s instructions.
3. MIG weld joints where applicable.
4. Clean the panel with a solvent wipe.
5. Treat bare metal areas using an etch phosphate
process.
6. Re-prime affected areas as necessary as for
rectifying transit damage.See this section.
7. Treat the inner faces of lap or butt joints with a
suitable cavity wax.See Sealing and Corrosion
Protection.

PAINT Clinch Panels (eg Door skins etc.)
1. Abrade primer on new and existing panel joint
faces, and clean using a solvent wipe.
2. Apply metal-to-metal adhesive where applicable.
3. Where joints are to be spot welded, apply
suitable weld-through, zinc rich primer to weld
areas.
4. Where joints are to be MIG welded, apply zinc
rich primer in adjacent areasbut leave the
welded area untreated.
5. To retain the panel whilst clinching the flanges,
tack spot weld or plug weld as appropriate.
6. Clean the panel with a solvent wipe.
7. Treat bare metal areas with a suitable etch
phosphate process.
8. Re-prime affected areas as necessary as for
rectifying transit damage.See this section.
NOTE: Replacement doors, bonnets and
tailgates must be treated with a suitable
seam sealer on clinched seams, following
the primer coat.
Paint Refinishing
1. Seal all accessible exterior and interior seams
with an approved seam sealer. Certain joints
such as sill lower flange seams must be left
unsealed.
2. Apply a suitable anti-chip primer where
specified.
3. Apply a two-pack paint refinishing system.
4. Repair any damage to underbody sealers either
at this stage or before paint operations.Paint Repairs
Before carrying out paintwork repairs, the vehicle
must be thoroughly cleaned using either a steam
cleaner or high-pressure washer.
Wash locally repaired areas using a mild
water-mixable detergent and wipe them clean with
solvent, immediately prior to paint application.
Abrade damaged paintwork where bare metal has
been exposed until the metal is clean and extends
beyond the area of immediate damage. Treat the bare
metal with an etch phosphate to remove all traces of
rust and provide a key for new paint coats. Re-treat
the affected area using either a separate acid-etch
primer and two-pack surfacer or an integrated etch
primer/filler, and follow with a two-pack paint system.
Those surfaces not receiving paint must be treated
with a cavity wax following paint operations.

RECHARGING
Service repair no - 82.30.02
WARNING: The air conditioning system is
charged with a high pressure, potentially
toxic refrigerant. Repairs or servicing must
only be carried out by an operator familiar with
both the vehicle system and the charging and
testing equipment.
WARNING: All operations must be carried
out in a well ventillated area away from
open flame and heat sources.
WARNING: Wear eye and hand safety
protection.
CAUTION: Overcharging air conditioning
system will cause excessive head
pressure.
An air conditioning portable Refrigerant Recovery
Recycling Recharging Station for use with R134a
refrigerant incorporates all the features necessary to
recover R134a refrigerant from the air conditioning
system; to filter and remove moisture; to evacuate and
recharge with the reclaimed refrigerant. The unit can
also be used for performance testing and air
conditioning system analysis.
The operator must adhere to the equipment
manufacturer’s instructions.
Refrigerant Recovery
1.Remove dust caps from high and low pressure
connectors.
2.Connect high and low pressure hoses to
appropriate connections.
3.Open valves on connectors.
4.Turn valves on refrigerant station to correct
positions.
NOTE: Operate the refrigerant station in
accordance with the manufacturers
instructions.
5.Turn Process switch to correct position.
6.Turn Main switch to’ON’.
7.Allow station to recover refrigerant from system.8.Close valves on refrigerant station.
9.Turn Main switch to’OFF’.
10.Close valves on connectors.
11.Disconnect high and low pressure hoses from
connectors.
12.Fit dust caps to connectors.
13.Open tap at rear of station to drain refrigerant oil
recovered from system.
14.Measure and record quantity of refrigerant oil
recovered from system.
15.Close tap at rear of station.
Evacuation
CAUTION: Whenever the refrigerant
system is opened, the receiver/drier must
be renewed immediately before evacuating
and recharging the system.
1.Remove dust caps from high and low pressure
connectors.
2.Connect high and low pressure hoses to
appropriate connections.
3.Open valves on connectors.
4.Turn valves on refrigerant station to correct
positions.
5.Turn Process switch to correct position.
6.Turn Main switch to’ON’.
7.Allow station to evacuate system.
NOTE: If the vacuum reading is below
700mmHg after 15 minutes, suspect a leak
in the system. Partially recharge the
system and check for leaks using an electronic
leak tester. Check suction lines first, then run the
compressor for 5 minutes. Next check the high
pressure lines.
NOTE: The system must be evacuated
immediately before recharging
commences. Delay between evacuation
and recharging is not permitted.
