Body Leak Diagnosis and Repair

GENERAL INFORMATION.

Successful repair of body leaks depends on correctly performing diagnosis to locate

faults and is achieved by adjusting the relative position of body elements and body equipment, as well as by using special repair sealants.

The first step is determining the conditions under which water enters the body. For example, water may enter the body when parked on a sloped surface, or may enter only the spare wheel compartment

etc. Once the leak zone is approximately

determined, the exact location of water entry can be quickly

determined using a water or air jet from a hose. If the leak point cannot be found, perform a full body leak test using

special equipment. During diagnosis and repair

of the body, it may be necessary to remove some trim panels and part of the

body equipment.

Warning.

It is necessary to accurately determine the point where water enters the body before

taking any measures to eliminate the fault. Otherwise, only a temporary effect will be obtained. Further diagnosis and repair may be

significantly complicated.

Inspection of the suspect area should continue until

all water entry paths into the body have been found.

Body Leak Test Using a Water Hose

During this test, an assistant must be inside the vehicle to monitor

water entry into the body.

Use a hose without a nozzle guide.

Start the test from the lower part of the suspect area and gradually

move upward.
