Interior leaks

[atk1]

Hey, what are the typical places CFs let water/rain in from? I just noticed water running down into and thru the side tray above the drivers side front wheel arc. Most vans Ive seen have rust in the front floor area where u put your feet. Those rear side windows can leak abit thru the bottom rubbers too. How do u leak proof these vans? Do u seal up that gap under the bottom corners of the windscreen frame or something?
Cheers

get a chalking gun and some windscreen sealer and seal up the whole windscreen rubber (outer edge) and clean up the mess with petrol or wax and grease remover (prepsol), waste of time just doing bits, you have to do the whole thing.

the winscreens are prone to leak as they are never sealed - never use silicone, its attracts water

side windows are the same

top of doors can leak if the rubber is shot

under the front wheel arch is a commen spot to rust, i call this a design fault as the water sits up in a panel allowing the rust to eat away that panel, the bottom of the door pillar and guard top section.

Also gutters, if your van has had roof racks or holes drilled in the gutter to let water out, or for aerial or even had rust repairs the seam in the gutter will leak allowing water to get in, rust then the water travels down the front screen pillar (and stays in the panel the sun visors mount to) and rust from gutters to the section mentioned above.

Cheers Busy, yeah Im gonna get a new windscreen rubber. I notice theres always abit of water that sits in the front of the passenger side rear wheel arch, just in behind that pillar. I have no idea where thats coming from but I know its not from the window above.

Don't forget to seal the rubber where the wiper arms are, that's where mine was leaking, took weeks to find this out... Matt will PM tomorrow in regards to the Sealer, just catching up on all the work

another way water can get in is from your front doors, ideally you should have plastic under the door panel (stick it on with windscreen sealer), this is a very common place for jap cars too.
Don't use tape to hold plastic down as it will dry up and come off allowing water to leak into the inside.

The best way to find a water leak is like this:
get 2 people; 1inside van, the other squirts the hose on the van.
If you know the general area then have the water land in that area.

Notice I said land and not squirt, you want to point the hose into the air so the water falls onto the van as your trying to do what the rain does. If you squirt the hose into windows and stuff be sure to wear a rain coat as you WILL get wet as the hose can go where the rain can't (angle wise).

Water leaks can be a real pain to find, last year I fixed my girlfriends car, was always wet behind the front seats, I tracked it down to a tail light leaking
