Air conditioning system precautions
General
The air conditioning system contains fluids and
components which could be potentially hazardous to
the service engineer or the environment if not
serviced and handled correctly. The following
guidelines are intended to alert the service engineer
to potential sources of danger and emphasise the
importance of ensuring the integrity of the Air
Conditioning operating conditions and components
fitted to the vehicle.
Where necessary, additional specific precautions are
detailed in the relevant sections of this Manual which
should be referred to prior to commencing repair
operations.
The refrigerant used in the air conditioning system is
HFC-134a (Hydrofluorocarbon) R134a. Always
adhere to the following precautions:
WARNING: Servicing must only be carried out by
personnel familiar with both the vehicle system
and the charging and testing equipment. All
operations must be carried out in a well
ventilated area away from open flame and heat
sources.
WARNING: Do not allow a refrigerant container to
be heated by direct flame or to be placed near
any heating appliance. A refrigerant container
must not be heated above 50
°C.
Do not leave a container of refrigerant without its
cap fitted. Do not transport a container of
refrigerant that is unrestrained, especially in the
boot of a car.
WARNING: Do not smoke or weld in areas where
R134a is in use. Inhalation of concentrations of
vapour can cause dizziness, disorientation,
incoordination, narcosis, nausea or vomiting.
R134a is odourless and colourless. Do not
handle or discharge in an enclosed area, or any
area where the vapour and liquid can come in
contact with a naked flame or hot metal. R134a is
not flammable but can cause a highly toxic gas.
WARNING: Do not allow fluids other than R134a
or compressor lubricant to enter the air
conditioning system. Spontaneous combustion
may occur.WARNING: R134a is a hazardous liquid and when
handled incorrectly can cause serious injury.
Suitable protective clothing, consisting of face
protection, heat proof gloves, rubber boots and
rubber apron or waterproof overalls, must be
worn when carrying out operations on the air
conditioning system.
WARNING: Due to its low evaporating
temperature, R134a must be handled with care.
R134a splashed on any part of the body will
cause immediate freezing of that area. Also,
refrigerant cylinders and replenishment trolleys
when discharging will freeze skin to them if
contact is made.
WARNING: Under no circumstances should
refrigerant hoses be disconnected without first
discharging the system.
Do not disconnect any pipes in an air
conditioning refrigeration system unless trained
and instructed to do so. A refrigerant is used
which can cause blindness if allowed to contact
eyes.
WARNING: Refrigerant must always be recycled
before re-use to ensure that the purity of the
refrigerant is high enough for safe use in the air
conditioning system.
Recycling should always be carried out with
equipment which is design certified by
Underwriter Laboratory Inc. for compliance with
SAE J1991. Other equipment may not recycle
refrigerant to the required level of purity.
A R134a Refrigerant Recovery Recycling
Recharging Station must not be used with any
other type of refrigerant.
Refrigerant R134a from domestic and
commercial sources must not be used in motor
vehicle air conditioning systems.

CORROSION PREVENTION AND SEALING
LEAK DETECTION 77-4-31
LEAK DETECT ION
Water Leaks
Where water leakage is involved, always adopt a logical approach to the problem using a combination of skill,
experience and intuition. Do not reach a conclusion based only on visual evidence, such as assuming that a wet
footwell is caused by a leak emanating from the windscreen. It will often be found that the source of the leak is
elsewhere. Use of the correct procedure will increase the chance of locating a leak, however obscure it may seem.
Tools and equipment
The following tools and equipment are recommended for the purpose of detection and rectification of water leaks:
1Garden sprayer (hand-operated).
2Wet/dry vacuum cleaner.
3Dry, absorbent cloths.
4Battery torch.
5Small mirror.
6Weatherstrip locating tool.
7Trim panel remover.
8Small wooden or plastic wedges.
9Dry compressed air supply.
10Hot air blower.
11Sealer applicators.
12Ultrasonic leak detector.
During leak detection, the vehicle should be considered in three basic sections:
lThe front interior space.
lThe rear passenger space.
lThe loadspace or boot.
Testing
From the information supplied by the customer it should be possible for the bodyshop operator to locate the starting
point from which the leak may be detected. After the area of the leak has been identified, find the actual point of entry
into the vehicle.
A simple and effective means in the first instance is an ordinary garden spray with provision for pressure and jet
adjustment, which will allow water to be directed in a jet or turned into a fine spray. Use a mirror and a battery-powered
torch (NOT a mains voltage inspection lamp) to see into dark corners.
The sequence of testing is particularly important. Start at the lowest point and work slowly upwards, to avoid testing
in one area while masking the leak in another. For example, if testing started at the level of the windscreen, any water
cascading into the plenum chamber could leak through a bulkhead grommet and into the footwells. Even at this point
it could still be wrongly assumed that the windscreen seal was at fault.
Another important part of identifying a water leak is by visual examination of door aperture seals, grommets and
weatherstrips for damage, deterioration or misalignment, together with the fit of the door itself against the seals.
Sealing
When the point of the leak has been detected, it will then be necessary to rectify it using the following procedure:
1Renew all door aperture seals and weatherstrips which have suffered damage, misalignment or deterioration.
2Check all body seals to ensure that they are correctly located on their mounting flanges/faces using a lipping
tool if necessary.
3Dry out body seams to be treated using compressed air and/or a hot air blower as necessary.
4Apply sealant on the outside of the joint wherever possible to ensure the exclusion of water.
5When rectifying leaks between a screen glass and its weatherstrip (or in the case of direct glazing, between the
glass and bodywork), avoid removing the glass if possible. Apply the approved material at the appropriate
location (i.e. glass to weatherstrip or glass to body).
