Water Leak Diagnostic Procedure
This procedure has been developed to aid diagnosis and rectification of water ingress on Defender vehicles with the aim of
providing a right first time fix .
The procedure provides suggested points of water in gress and guidelines for a recommended fix.
It is assumed the technician working on the vehicle will be at least level 3 trained and normal vehicle service protection
equipment will be used where appropriate i.e. seat covers, wing covers etc.
Water Leak Diagnosis
There are certain basic tools required for effectiv e water leak detection the following are a few reco mmendations.
There are several adaptations of tools that can be used, for example a watering can rose attached to a hosepipe to create a
spray, or a new sealant tube nozzle attached to a hosepipe can be very effective to direct water into awkward corners, there are also several ready made hosepipe nozzles availa ble from DIY stores which can be switched through s everal different
water patterns, and finally not forgetting a normal car wash. With the exception of a car wash initial diagnosis is more
accurate if carried out by two people, one inside and one outside the vehicle, the perso n outside can direct the water onto
the areas where the leak is suspected to be enterin g, and the person inside can inspect with a 12 volt hand lamp to confirm
the entry point.
It is worth bearing in mind that the location that the water appears in the interior of the vehicle, m ay not be the leak
source, for example water lying in the passenger footwell c ould be entering on the drivers side and running
across, behind the fascia . In order to find the water entry point, trim or c omponents may have to be removed.
Often when water has been entering over a period of time, the water entry point can be located visually by following the
stains or tracks left by the leak.
