LEAKS WATER - IDENTIFICATION AND CORRECTION
LIGHT TRUCK:
1984-91 ECONOLINE
This TSB Article was originally published as TSB 84-19-15 on September 12, 1984. It is being republished because the basic water leak corrective procedures and techniques remain applicable for the more recent models as well.
ISSUE:
The water leak identification and correction procedures outlined in this article are the most common conditions you may encounter. It is unlikely that you will ever find it necessary to perform all of the possible corrections on a single vehicle. Each vehicle is unique and, therefore, careful attention is required in evaluating the vehicle and making the necessary corrections.
ACTION:
If service is required, use the following procedure to identify and correct the water leaks.
DIAGNOSING WATER LEAKS
The actual sources of these various water leaks may often be misleading.
^ The spot where the water shows up is not always the location of the trouble.
^ Do not always rely on the service order, or even the customer, to pinpoint the actual leak area.
^ The description of the water leak will usually reflect only where the water is noticeable, not necessarily where the cause is located.
GENERAL TEST PROCEDURES
Although every dealership has its own method for testing water leaks, the following methods will be helpful to the technician in solving the more difficutt and persistent water leaks.
NOTE:
DETECTION OF WATER LEAKS IN THE REAR CARGO FLOOR AREA MAY BE ENHANCED BY PLACING A LARGE LIGHT BULB IN THE CARGO AREA, RAISING THE VEHICLE ON A HOIST AND CHECKING THE FLOOR PAN JOINT FOR ANY LIGHT SHINING THROUGH.
LOCATION OF "WET AREAS
Areas to examine for potential wet spots are shown in Figure 1 and are described as follows:
a. Front Door Step Well
b. Base of "B" Pillar on Floor
c. Side Door Step Well
d. Base of "C" Pillar on Floor
e. Forward of Rear Wheelhouse on Floor
f. Behind Rear Wheelhouse on Floor
g. Around Fuel Filler Housing on Floor
h. Base of Rear Cargo Doors on Floor
i. Rear Corners of Floor
j. Miscellaneous - All Window and Door Weatherstrips
SEALING MATERIALS
A list of sealing materials is shown below.
1. Silicone Rubber Adhesive
^ Clear - Ford (D6AZ-19562-AA) or 3M 08661
^ Black - Ford (D6AZ-19562-BA) or 3M 08662
These are rapid curing adhesives/sealants formulated for such uses as sealing leaks, remounting trim and servicing torn weatherstripping adheres to a wide variety of surfaces.
2. Weatherstrip Adhesive
^ Yellow Colored - Ford (E8AZ-19552-A)
This adhesive holds weatherstripping on doors, bodies, cowl ventilators and other locations. It is used to service loose weatherstripping or install new weatherstripping. It is also used to bond numerous rubber-to-metal, rubber-to-wood, rubber-to-cardboard and rubber-to-rubber surfaces. It stops leaks in windows set in rubber mouldings. It sets up fast.
3. Joint and Seam Sealer
^ White - 3M 08646 (Cartridge Type)
^ Black - 3M 08648 (Cartridge Type)
This joint and seam sealer is a firm setting, but flexible sealer for interior and exterior body joints and seams. Typical applications are in floor and wheelwell areas. It skins over quickly and can be painted in about 30 minutes.
