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).
