Before anything else check thoroughly for rust holes in both wheel arches. Peel back the boot carpet and shine a bright light around the wheel arch while an assistant looks for light penetration inside the boot. This may help in spotting small holes. Even a tiny hole can allow significant amounts of water to enter the boot. Pay particular attention to the towing eyes that are welded to the wheel arch. Water can penetrate up between the towing eye and the wheel arch and then into the boot area.

The following chart gives details of points of entry where water may get into your boot together with some information to assist in diagnosis and rectification. You can establish most of this with 2 people and water testing just deciding who is the unlucky one to get wet. Kaz always loses on this one.




Tailgate Glass seal

(A in diagram 1)

Water passing between seal & glass or between seal & tailgate

Reseal using a window sealer paying particular attention to corners. Check also that wiper motor is not fouling parcel shelf as this tends to push screen outwards and break seal on lower edge.

Drip Moulding flange

 (B in diagram 1)

Crack or pinhole in drip moulding. Sealant Can allow water to enter and run down between e posts & drip moulding & emerge below light seal. Note water entry at this point can be mistaken for a light leak

Reseal flange with sealant note it may not be necessary to remove chrome strip to carry out this operation if a suitable tool such as a small screwdriver is used for the application of the sealer.

Quarter light (C in diagram 1)

Leaking between seal and body or seal and glass

Reseal insuring that quarter light is set correctly in aperture

Wiper motor (D in diagram 1)

Water entry passed rubber grommet in tail gate glass

Gain entry to grommet and apply sealant to area and reassemble



Tail lamps (E in diagram 1)

Water passing between lamp and body and entering boot

Apply sealant around lamp gasket over lapping on to body and lamp

Rear motive (F in diagram 1)

Water entry through holes for plinth securing bolts

Ensure grommets are fitted between plinth and body and apply sealant between grommets and body

Rear bumper mountings

(G in diagram 1)

A loose mounting or missing rubber gasket will allow water to travel along mounting bolts in to the boot

Insure rubber gaskets are fitted apply sealant around bolt heads and tighten bolts

Tailgate seal (H in diagram 2)

Seal not fitting correctly on top corners of flange a build up in this area can cause water to enter seal carrier and travel down the seal dripping out at lower point

Dress flanges to ensure seal fits properly make sure flanges are fully home ensure that seal is fitted with uppermost lip pointing outwards

Wiring sheath between tailgate and E post left hand and right hand (I in diagram 2)

Water passing between grommet and tailgate aperture and running down inside E post into boot

Check for cracks splits in sheath and ensure grommet is fitted correctly in E post. If necessary apply sealant between grommet and E post

Tail gate aperture seams and back panel wing vertical seams

(J in diagram 2)

Water entry through cracks or pinholes in sealer

Reseal aperture seams and back panel wing seams and repaint

Rear wheel arch (K in diagram 2)

Water entry through double panel joint on rear lower flange

Seal joints inside boot adjacent to sunroof drain tube

Sunroof motor (if fitted)

Water entry passed motor fixings in boot floor

Remove motor and apply sealant around fixing bolt threads and refit motor

Tailgate support struts

Water entry passed mounting struts on tailgate aperture

Remove nut apply sealant to both sides of mounting and washer and tighten nuts

 Verify by water testing again.
