Common Rain Leaks?

[zeisshensoldt]

It started to rain today, so I thought it would be a good idea to see what the inside of the cab looked like. Surprisingly it wasn't leaking at all from the soft top or windows, but instead water was pouring in from underneath the instrument panel and from under the steering wheel. Is this a common place for rain leaks? Also, I was wondering about the seal around the in-tank gas pump is that a good place for water to get into the fuel?

Check the cowl at the base of the windshield for pin holes.

A bad seal under the folding windsheld frame will cause and under dash water leak.

This one actually made me get up, walk outside and look at my 72 KJ M35A2. True story! Unless you have some bad rust issues, I'd be willing to bet the water is sneaking in under the windshield possibly near or under the safari latches, through the gap between the windshield frame and dash panel, rolling down inside the dash and down to the floor. I could be wrong here, but is it even possible to completely seal a deuce windshield and still be able to open it? Anyone?

Here is how I fixed the pin holes in my wifes truck. I just ran a wide bead of caulking that covered the pin holes. The same thing should stop the leak DH posted about.

I'll take a look again. What about around the top of the in-tank fuel pump, common for water to get in around the seal?

I keep an umbrella handy in mine! A mask and snorkel ain't a bad idea either!


Just joking!

I doubt the tank pump cover would leak unless it's been left loose, gasket removed, etc., but it's also covered by the bed unless you get some serious blowing rainstorms, I wouldn't worry too much about it. Any doubt? get a new gasket and make sure it's tight. Not too expensive but if finances just aren't allowing, the waxed cardboard used in 1/2-gallon milk cartons makes awsome gasket material, and you can use the original gasket for a pattern/template.

Almost all the deuces and five tons we have had in the shop have rust issues right where the cowl and windshield frame meet. I would bet that if you took a wire brush and ran it along that joint wyou will find several pin holes. We have been cutting the entire cowl out and replacing the steel with a continuous weld. We then grind it smooth, prime and paint it. Just be sure to double up the area where the hood bolts get mounted before welding. If in doubt of you welds, apply caulk for the entire length of the joint. after prime and before paint

Measure two inches above the pavement all the way around. Then check everything for leaks above that.

My cucv leaked pretty bad through the windows and seal around the top but luckily i had plenty of rust induced drain holes in the floor boards to prevent puddles

 

[03silverado]

Everywhere pretty much unless you've replaced all of the gaskets etc.

I'm pretty sure these things leaked a little right off the assembly line. They just aren't built that tight.

Best thing to do to prevent leaks is do what I did. Build a shed to park it under.

 

[Welder Sam]

Mine leak there too bro. We got your rain a day before

 

[goatijoe]

Mine leaks even where the new seals are!

I believe the way to receive the shortest list of spots where these trucks leak would be to ask where do these trucks not leak

That's a lot of water! Might want to strap a lifeboat to the side of your truck.

Air in the tires!!

Ive allways heard and found it true if it aint leaking it must be empty.

I did check the cowling and there is a large rust hole in the center about 6 inches in length. Then there's a few other small holes on either side of it, so silicone to fix this?

Grind it a little and MIG weld a patch on it like the military does. All my trucks were patched like that.
