    Has any one replaced a windsheild?
    Do you need a hot wire to cut them out or can you use some thing else?
    The corner is crack I think it is fine but the wife hates it.
    Found a windshield in a 95 truck going to trade some stuff I have laying around for it.

    I have NEVER had luck when replacing a windshield. NEVER. I have tried it and tried it a few times. Never again. It either cracked when I was putting the blasted thing in, or I never got it sealed right and it leaked.

    Try it if you want, but good luck. For me, it's better left to the Pros.

    Pulling a windshield is really easy. I have done hundreds, at the factory we used the special knives made to cut them out. I don’t use that anymore, I use either the wire you can buy at any auto parts store or a guitar string. If you use the guitar string buy a few.
    First of all do this on a warm day, the warmer the better if you have never done one before.
    Tools you will need.
    2 Pairs of small needle nose vise grips, or 2 wooden dowels the wife's broom handle cut into 2 - 6” lengths is good.
    a upholsterers needle, or the largest needle you can find at a sewing shop, around 1/32” thick
    The replacement caulk to put the window back in with, I like the stuff in the roll but you can use Urethane its messier but works well and really seals well.
    A replacement trim molding will also be needed.

    Now take the interior trim on the sides out, slide the needle along the windshield and push it threw the urethane till you hit the outside steel where the window is set in. then remove the needle.
    After that put the wire threw and wiggle it out the outside of the window, you may have to use the needle to get it out so you can grab it with a pair of vise grips.
    Now lock the vise grips on the wire and pull 2 or 3’ of the wire threw to the outside.
    At about 2 or 3’ inside on the wire inside lock the other pair of vise grips.
    Now it’s a matter of simply sawing, (pulling the wire in and out) in the direction you are cutting all the way around the window once.
    Once you have the window cut all the way around you will need a helper, who may come in handy when cutting to. One of you take one side and one of you take the other and just push the window out.
    Remove all the old urathane with a stiff putty knife and you have it out.

    I forgot, First thing you need to do is remove the outer molding. Just grab it at the bottom where it sticks out under the hood with a pair of vice grips and pull.
    Now if it has the old chrome molding it’s different to remove you need a special tool.

    Dam my memory is shot.

    windshield replacement

    Steve I didn't mean to hurt your feelings, sorry dude.

    I spent 2 months in the 80’s when GM went from the flat back window on the Ciera to the bowed window doing nothing but pulling and replacing them.

    You have to get all, and I mean all the old urethane off the steel and the glass for a good seal. I have used an air chisel sometimes on the steel frame when it’s real hard.
    There is no substitute for experience, If you can find a broken one to practice on in a bone yard try my method. Most of the body shop guys I know use the wire method, the cutting tool is for the pros.
    When you put the new urethane or caulk type sealer on the windshield pit it one the our edge of the glass and don’t squish it down to hard on the glass. When you set it in the frame use 2 people and as warm a day or garage as you can get, if you use the chalk type sealer. Then just lean on the windshield with both hands on both sides.
    If you use the urethane make sure you use a good chalking gun and cut a V groove in the end. it will flow better. put down about a half inch high bead. Then just lean on the windshield with both hands on both sides.

    I'm just playing, it's all good. :)

    Now that I think about it, it really can't be all the difficult to replace a windshield, I mean look at the guy that replaced my last window ...

    I called the dealer (GM) and they said the trim molding I can reuse it for that year. That it will not tear when i take the molding off. Does this sound right 84feiro? I used to have a feiro it was the yaer before the gt. it had the v6 5speed sunroof. That was a fun car got me in trouble on many differnt occasions sometime the car was not moving and I got introuble in it.

    You can reuse the molding if it doesn’t stretch or break. The place to get one is a auto glass replacement shop. they now use one that wraps around the glass before you put it in place. And they will also have the original type, Just call or stop down and tell them what it is going in, or on what ever is the right term. Also don’t wait to put it in to long after you set the glass in if you use the original.
    I have the 84 Fiero still, use it for parts now for the 86 SE V6 I now drive. I hear you about getting in trouble with it, even when it’s not moving. My wife got stopped in a parking lot in town by a cop who just wanted to see the engine in the back. We are older now, my wife Melanie is 44 and I’m now 51 the end of this month so we generally aren’t racing around with it, all the time. But in the summer it is a daily driver and fun, just one big pain to get out of.
