Does our trucks have a rubber gasket that surrounds the windshield? I am getting water inside the cab and I can see it at the top of the windshield trim on passenger side, and behind the dashboard on passenger side. I'd like to order one if possible, or if there is a way to remove the aluminum/chrome trim without damaging it and just put some gasket sealer on it... I have no clue.

I did see a post about adding garage door strip to the cowl area, and mine does look beat up so I will be doing that. Also removing the cowl and cleaning it, putting down some flex seal or something to stop that leak as well if that's how water is getting in on the bottom..

Any tips or clues would be awesome.

Thanks gents!

 

I think it's butyl rubber, someone who has done one can verify that.

 

I haven't done one, but word around the forums is it's butyl, can get it in a roll or in a tube I believe. In addition to the windscreen seal, water gets in from the lower drains being clogged with leaves and pine needles and critter nests. That's corner of the windshield, straight down through the cowl. Tends to have water come in around your left foot IIRC. Lots of threads on that as well.

 

It does use Butyl "tape" that comes in a roll you want it in 5/16" I asked what size tape and just installed my glass last Sunday.

Make sure the pinch weld is clean and if rusty needs to be fixed & painted before the tape goes down.
Make sure the pinch weld & glass are free of oil & dirt before putting the tape down on the weld.
I used gloves so my hand oils would not get on the glass when installing it.
I also had gaps at the top corners the tape did not touch the glass but was touching in the top center of the glass.
I think that was because the roof looked like someone walked on it and may have hurt the front top edge?
I had a little of the tape left over and stuffed it in the corners to seal them/

You forgot to say the part about how our trucks don't have a solid roof and needs the flexible butyl tape and how the modern adhesives won't cut it, and that the windshield trim helps hold the glass tight against the tape. Thanks for dropping in though, I was way too lazy to go back and find your post about it, every time I scroll through your thread looking for something I end up missing in and have to read it top to bottom twice lol

 

The trim has nothing to do about holding the glass in it is there to finish off the body and is only for looks.

I had to prove this to a DMV officer who was going to fail my inspection because I did not have the trim on, no clips at the time. I banged on the glass from the inside almost breaking it to show the trim was for looks only.
He passed it but made a note on paperwork in case it fell out. Glass is still in the car 30 years later.

I am not a fan of gluing it in like the new cars are done as it will not let the body flex as it should and can Crack the glass.

Fuzz, I'm at the step where I need to transplant my windshield. On the cab I repainted and am going to install the window in, I cut down the existing windshield urethane to about 1/16" thickness and taped over it so paint wouldn't get on it. I did it this way because I initially thought I was going to have to use urethane in a tube for reinstallment but this Butyl tape seems much easier. My question is, can I do the Butyl tape right over the existing urethane? Do I need to prime the existing urethane first?

 

I did a little more research and it appears that the factory windshield seal was a butyl product or similar. When I was cutting it down it had a piece of string in the inside. So, that being said, with a clean existing cut down butyl (I think), would I need to prime the existing sealant or just put the new butyl tape over existing?

 

19562 = D9AZ-19562-A .. Butyl Tape Kit used when windshields are either replaced or resealed.

Says refer to paint section because after the paint is listed, the oils, lubricants, sealers and etc. are listed.

All auto glass shops have this tape because most new vehicles sold in the past 40 years do not use gaskets.

 

when I get on my pc after work I will answer your questions.

Ok when I painted my truck I cleaned all the old sealer off the pinch weld.
I then did the needed body work for any rust, etc. primed (body work primer) & painted when I painted the cab.

With a helper I test set the glass in the opening to make sure the adjustable blocks at the bottom were adjusted right for up / down.
I then made sure it was even left / right and then used masking tape at the bottom from glass to the cowl vent so when I placed the glass in I could line up the tape from the glass to the cowl to make sure it was good left / right.

So the pinch weld had just paint on it and the glass I made sure wash really really clean.
I wiped down the pinch weld with a oil / grease remover just to make sure no oils from my hands were on it, I also did the glass.
I put the seal on the pinch weld to the edge to make sure it would hit the glass.

Then wearing rubber gloves not to get hand oil on the glass helper & I fitted it to the truck.
Once set you can see where the tape has hit the glass, press the glass to the tape all the way around to set it better.
I found the 2 upper corners of the glass did not touch the glass so I took a little of the left over tape and pushed it into the void area.

I did not use any of that "glass primer" as it was never used back in the day, only with the glue they use on todays cars & trucks.

Got to say when I washed the truck about a week later I had no leaks.

ps; I have a windshield I did this way over 30 years ago and it is still leak free so I don't see why this will not be the same way.
pps: yes I got up at 1am for work and still up for a few more as I got to get up again at 1am

 

I appreciate it Dave, this was very helpful. I was on Gary's site yesterday and actually saw the post you made regarding this topic but you painted the picture in my head on this post very well.

 

Your welcome
Year I needed to know how thick the tape should be as it comes in think 3 different sizes.
