Subject: <all>Re: Windshield install...(long) and UUC hidden value
Jefrem(and others) asked me offline about windshield installations:
I haven't replaced the windshield on an 02 before. I also am not a
windshield professional. I have, however, replaced or assisted in
replacing the windshield on several cars, including my 535i,a VW
bug(curved windshield), a Karmann Ghia, a Toyota Pickup, and a '70s
The use of a sealant is not always necessary. Of the cars above only the
Toyota and Dodge needed a sealant. In these cases a construction
adhesive such as PL2000 was used(not my choice,I just helped on those).
I am sure there are specialized sealants by 3M but I have not had the
occasion to look them up.
The most important thing to be careful of is to not crack the windshield
while installing!! It happens even to the professionals. It is more
likely with used glass and usually happens when you get frustrated that
the gasket is not sealing properly and you apply too much pressure to a
small area. If you do undertake this yourself have a couple friends over
that you can trust to apply pressure to the windshield while you seat
the gasket in its channel.
I'm 95% sure your 02 windshield gasket has metal or plastic trim inserts
that serve to lock and seal the gasket in place. You may also need to
remove some trim pieces inside the car to get access to the gasket.
To install a new windshield and gasket:
- Make sure the gasket is pliable, a warm sunny day is preferable but
you have other options(such as a hair dryer) to warm the rubber.
- Fit the gasket around the new windshield,you may need a shot of
silicone spray here and there. Don't apply too much as you do not want
the gasket slipping off the glass.
- Cut a piece of cotton clothesline about 1 meter longer than the
perimeter of the gasket. Insert this cord into the outer channel of the
gasket, overlapping the ends of the gaskets at the center of the bottom
of the windshield.
4)Saturate the channel with silicone spray.(if someone knows a better
rubber lubricant for this purpose,post it please!)
5)Place the windshield,gasket and cord in the windshield frame with the
cord ends inside the car. Line up the windshield in it's frame.
6)Here's where the 2 friends come in handy. Put one in charge of
applying general downward pressure and making sure the windshield stays
aligned. Have the other one apply localized pressure as you,working from
inside the car, SLOWLY pull the cord out of the channel, thus seating
the gasket. Popsicle sticks,thin screwdrivers, and other improvised
tools help in getting it seated right. You may need to backtrack a few
times and reseat a section you did before.
- Insert locking strip as described in previous post and take a test
drive, checking for leaks. If any are found,take out the locking
strip,apply sealant between gasket and frame in area of leak, and
reinstall locking strip before the sealant sets. If you are really good
you can probably figure out where these spots will be before you install
the locking strips the first time. They are usually in the center of the
bottom and top of the windshield, but you often don't know until the car
has been driven a while. Most of us have had to take a car back to the
professionals for a leak they missed so don't fell bad.
Getting this done,while not a UUC upgrade, really proved to my
girlfriend that I knew what I was doing around cars. After a windshield
replacement(where she was recruited to help apply pressure to a
reluctant windshield) I got no hassles when I would announce that I
needed to go help a friend work on their car at their house, when I
really was making UUC upgrades. Hell,I think she thought if they came
over to my house she might get recruited again for more than a beer run.
So she gets peace and quiet to herself and I get to work with my buddies
on cars. What a great setup. Too bad we broke up.(I wasn't ready to
Anyone with more BMW specific windshield info, feel free to add to the
above(I know it's not worth a hill of beans to e36 M3 owners,who have
the windshield as a stressed member.)
Please don't hold me responsible for cracked glass during installs! This
is the nature of the beast and you probably won't get it replaced from
place of purchase. My 535 windshield was $150(with roundel,not
aftermarket) as opposed to the $450 the glass shop wanted to replace it.
So even if I cracked one on install, I was still ahead $150(as long as I
didn't crack the second one!)
