Windshield cowl gasket

I bought a new windshield cowl gasket off ebay for $24. I have never replaced one of these before and i was wondering what the quality of the part was going to be. It actually seemed to fit really nice and look identical to the factory piece. Until i went to put the window back up and reattach the roll bar back to the windshield, not happening!

So i loosen the dash brackets up and pull back on the corner until i can get the bolts threaded in. And i eventually get it kinda put back but it is tilted forward a lot. So i attach the roll bars to the windshield frame and then draw the windshield back using the bolts that bolt the bars to the main hoop. It worked and im hoping if i let it sit like this a few days it will take shape like the one i replaced. Is this normal or is this just a poor fitting cowl seal?

Also, the factory seal had some kind of black sealant like some kinda RTV rubber black stuff that always stayed goopey. I am assuming the factory squirted this stuff in there to help keep rain out. I would like to find out what type of product it is and squirt it full again.

The good news is after 22 years my windshield frame still had zero rust.

Sounds like you did it correct. I've replaced a couple and if you're not careful you can crack the glass. I like to use ratchet tie down from windshield hoop to center roll bar to draw it in to start the bolts. Never seen goop sealer on mine but I think mine were built on a Friday.

Well I am glad i didn't crack it. I was a bit worried about cracking the glass because i had no help to pull back on the other side at the same time. I still have to fold it down again to touch up a spot on the dash thats rusted with por15 im not looking forward to putting it back down.

And after looking around for adhesives this seems to be the closest thing i can find to the black factory sealant that was used https://www.permatex.com/products/ad...esive-sealant/

Search posts by Raoul. He has a method to compress the gasket and not put the windshield glass in peril.

If the gasket is installed correctly, you don't need any sealer. That said, if rust has started it may be a good idea to use a sealer. As far as I know, the factory didn't use a sealer.

Good Luck, L.M.

I have 2 1994's that had black tar like substance on the outside where you can pull the foam rubber back. It was applied the entire length of the windshield. I was able to scrape it off with a credit card when i replaced it. I assumed it was extra measure of prevention to keep rain from running down inside and into the cab.

I did it kinda the same way i just didn't use a board and luckily my windshield didn't crack. I actually thought about doing it the way he did it since i was working alone but i was trying to get it done quick.

I loosely bolted the roll bars to the windshield frame. Then i was going to use the big T50 torx bolts that run though the main hoop to pull it back. The problem was that the bars were still about 2 inches from touching the hoop. So i had to stand in the back and reach forward and grab the frame and pull it back just far enough to gt a few threads started. Once started i switched to the other side and did the same. Once i got that far i tightened the 2 windshield frame bolts all the way on both sides.

Once all that was done i started tightening the T50 bolts going side to side to try and keep the tension somewhat even so i dint crack the glass. It worked so i guess it was a decent idea. And the factory setting on the bars pull it into the correct position so you dont have to mess with windshield alignment.

The new foam rubber just seems way to hard compared to the one i took off. Maybe it's just due to old age of the factory one but i dread putting the window down again because i know im going to be in for a fight to put it back up again.

You are aware they are still available through Mopar for close to the same price as aftermarket?

GLASS - WINDSHIELD for 1995 Jeep Wrangler

i had no idea i thought dealers wouldn't have anything for YJ's at this point.

I do remember going to the dealer about 15 years ago and buying a bell housing boot for a CJ7 though.

Does this look normal? Installed eight months ago. Could not get the roll out of the portion that seals to the outside of the frame. Rubber was so "oily" that 3M trim cement would not stick to it even after wiping with acetone. Just got a replacement for it and it's the same. I think it's time to order OEM and see if it is any different.

That does not look normal! I bought the cheapest one available on ebay for $24 that claimed to have a 10 year warranty.





And this is where the factory black sealant was applied a strip all the way across the bottom

I used a little bead of windshield silicone on the top of the cowl seal and it hasn't leaked since I put it in.

Update... i keep my YJ garaged so it was not a huge concern so i kept forgetting and putting it off. But today i remembered when i was at walmart when i seen some 3M Black Super Weatherstrip Adhesive #03602 for $2 so i bought it. It is black and it comes out of the tube very runny. I pulled back the new cowl seal i installed last year and ran close to a half a tube all the way across the bottom of the seal.

I was not sure how this stuff was going to set up and if it would be like the stuff the factory used. Well to answer that question no it's not! When i left and came back my cowl seal was bulged out, not good! So i tried to smash it back flat and it did not want to go it seemed like it wanted to stay pushed away from the windshield frame. I was not looking forward to replacing this gasket again so i gave up and walked away from it.

A few hours later i came back and the adhesive was starting to set up and get sticky. And when i tried to push the seal against the windshield frame it actually stayed in place. I just checked on it again and it's staying where it is supposed to be but it seems to be drying hard, not rubbery. Some of it squished out the top in one area and i tried to rub it off or scrape it off with a finger nail and it does not wanna come off!

I am not thrilled with the results because i know when i replace it in the future it's probably going to be a mess and impossible to scrape off the frame unlike the factory sealant but it definitely looks like it will keep water from running back behind the seal and rotting the frame out. Which is the main goal of putting sealant behind the gasket in the first place so i guess it's better than nothing.

**Need help with cowl seal** - bottom of seal keeps moving outward - JeepForum.com

Get some plastic razor blades to clean it up.

The seal fit fine to begin with and it was a cheap ebay seal. I just wanted to use sealent behind the seal to keep water leaking in from behind since the factory put some in there. The 3M stuff is not the same stuff though it's a completely different substance that dries pretty much hard. The factory adhesive was more like butyl rubber caulking for gutters because it stayed pliable, 3M stuff does not.

I am in the same boat. I saw on another thread that guys were having a hard time breaking loose hinges. Like having to heat em up and other stuff. Is this gonna be an issue? Are they even referring to these hinges? While the windshield is down, would it be a good time to consider replacing anything else?

Hinges will be a problem if you keep your jeep outside in the weather and or live in the rust belt. My jeep has been garage kept it's entire life and i never drove it in the winter to avoid the salt so my hinges work as well as they did they day it rolled off the assembly line. I your jeep is rusty your gonna have a hell of a time getting the hinges to move. If your wiper linkage is sloppy it would be a good time to replace the linkage bushings.

Also before you go and make a problem worse by trying to drill the hinge bolts out if you cant get the windshield to move or break a hinge trying too. grind the paint off the torx bolts and weld nuts to the heads of the bolts. The heat will melt the factory thread locker and they should come right out with a wrench. It sure beats removing the dash and trying to put nuts on the back side when you ruin the factory nut plates.

Wait, your jeep fits in your garage?!? I thought that was for my wife to store her stuff in?! :-) Thanks for the heads up on the wiper linkage though.
