windsheild question

[76bonanza]

I just got a new truck it has a new windshield and seal but i took it out in the rain today and it leaks like a siff dont know were the windshield was installed. Should I just take it to my local guy and have him reinstall it?

Any advice this is my daily driver cant be leaking.

thanks

It is probably leaking from the corners. I had a windshield done and it leaked. Went back to the installer and asked what sealant they used. Said none. The factory manual shows a thin bead of sealant about 12" out from each upper corner.

You could try to fix it yourself with a product called flowable silicone. I used it on another truck and it did the trick. Got it at a chain auto store and it is made just for this problem. Good luck.

MAybe they didn't put any sealant in?

If I take it to an install and ask them to selicon the **** out of it and reinstall will they do that? I really dont want to mess with it my self da- burb did they redo yours and stop the leak?

You are right. Sometimes glass leaks are a pain in the rear. This way if you pay a glass shop to fix the leak and it still leaks, take it back. You do not have to mess with it yourself.

[da-burb]

They wouldn't touch it. Usually you will break the glass on a removal. If you didn't install a new gasket this time around maybe they would do it for you. Cut the old gasket, remove the window and reinstall with a new gasket.

by the way, the flowable silicone takes about 3 minutes to do. I did it myself, but a helper pushing the windshield out with their feet a fraction of an inch would have made it much easier.

Can you explain the process to me? I guess an auto glass shop would not do the silicone thing for me?

i installed the glass with no sealer and a new gasket.there is no one who ever got the chrome in after the fact. fine 67

On another thread, someone mentioned that the cowl area leaks thru the sealant under the cowl cover at the corner of the cowl cavity near the windshield. The factory sealant doesn't hold up.

I always thought that one of my burbs was leaking thru the windshield, but when I crawled under the dash with a light while it was raining (don't try this at home ), I couldn't find any water leakage at the windshild gasket (again, while looking under the dash).

I'm convinced that the cowl leaks, not the windshield. I have yet to verify this, though, because I'm waiting till I tear down that burb to get under the cowl cover.

On these windshields they do not put any kind of sealent around the rubber. They just pute the rubber around the glass and install together. Which auto chain did you get that flowable sealent? Never heard of it. I have a new windshield in my Burb and the installer said the hardest part was putting the new rubber in with the new chrome piece in the rubber. Took him three times putting in and taking back out to get the crome the way he wanted it. But at the end he did a great job. Have not had it it the rain yet but would like to find some of that flowable sealent.

4x4poet were would it come into the cab from the cowl I was not aware they were conected unless it is rusted out some were. Mine was collecting on dash and dripping down at least most of it. Took mine to a windshield guy he put sealant under the rubber all the way around the cab and the glass with out removing the glass just stuck the end of the gun under rubber and went all the way around has not rained again yet but he said that will usually fix it he used urethane not silcone much better he said.

[da-burb]

here is the stuff I used. Name brand and you should be able to find it anywhere.

Thanks da-burb. I think I will get some and put around mine just to be safe.

Did he also say why the urethane would be better than the silcone You could always check for leaks with your water hose.

If water collects on the dash by the windshield, then you must have a leak around the w/s seal since only the w/s is above the dash. I thru out the cowl leak scenario just in case that could help.

As to the location of the under cowl cover sealant, there are sealant filled seams just below the outside of the w/s where each A-pillar meets the dash with the cowl cavity in front. The factory filled those seams with sealant that doesn't hold up. Any leak would come down the interior side of the firewall. It takes a close look under the dash to discern the difference, but I doubt that a leak at that seam could collect water on the dash. Could be wrong, as happens sometimes...

da-burb how did you use the flowable silicon on you windshield?

[da-burb]

peel back the gasket enough to get the nozel under the gasket. I did this from the outside of the truck. I started about 12" in from the top corner. At that point squeeze and slide it back to the corner. At the corner i put a little more in than I figured I would need since it should "flow" down the A-pillar.

It was a tight fit and I remember wishing I had another set of hand there to help either push the windshiled out a little from the inside or help pull back the gasket. I did have a tool in the tool box that helped out. I don't know what it is called or used for or why I even had it in my tool box, but it has a screwdriver handle with a 90 degree bend at the end and it tapers to a point. It lipped under the gasket well and you could pull the gasket away from the opening and inject the silicone.

Alot of Transport Truck windshields at set in with only the rubber seal, just like the back window in our trucks.
