3.
Connect the UV lamp and from the interior of the vehicle illuminate the affected area (Illustration 21).
4.
The leak is located as soon as a bluish reflection can be seen in the area of the water leak.
Note:
Light colors absorb a part of the test fluid.
Once a leak path has been identified, the test fluid must be thoroughly washed away using an appropriate cleanser.
APPENDIX 3
WATER LEAK TESTING PROCEDURE
The water leak detection can be carried out using one of 2 methods:
^
Using a car wash/jet wash when the ingress path is not clear.
^
Using a variable water spray gun, when the ingress path has been isolated to a specific area.
Note:
Before beginning with the following procedures, recommended Tools, Equipment and Materials can be found in Appendix 1.
USING A CAR WASH/JET WASH:
A car wash/jet wash should be used when a water leak ingress path is not clear.
If it is suspected that a vehicle is leaking water from e.g. the front lower door area, ensure the area is completely dry then:
1.
Have at least one person inside the vehicle while the car is being washed using the car wash/ jet wash checking for signs of water ingress.
2.
Look at the suspect area for signs of water seeping into the vehicle.
3.
Once water seepage/ingress has been identified, mark the general location.
Note:
When checking for signs of water ingress in darkened areas use a light.
4.
Ensure there is no water ingress in any other area of the vehicle.
5.
Once the car wash/jet wash is complete, return the vehicle to the workshop to perform the water leak test using the spray gun (see below).
USING A VARIABLE SPRAY GUN:
The variable spray gun should be used once the leak ingress path has been isolated to a specific area i.e. door, luggage compartment etc...
If it is suspected that a vehicle is leaking water from e.g. the front lower door area, ensure the area is completely dry, then:
1.
Have at least one person inside the vehicle checking for signs of water ingress.
