Sunroof seals


JAS

Recommended Posts

Hi all - I am installing new seals (felts) on my 1974 tii's sunroof (parts 5 & 9 in the schematic) - does the back felt (part 9) attach to the roof body or the sliding panel? I'm guessing the answer is the body but the old one is missing and there is no clear indication where it was previously.

Also, I assume I will need to pull out the sunroof and/or the headliner to get at the seal (part 8)?

Thanks to all that answered my question (a few months ago) about tracking down a short in the brake light/wiper motor circuit - turned out to be a burned out wiper motor. To allow it to "park" the wipers after the wiper was been turned off the motor has a hot lead - mine appears to have shorted out in the middle of the park cycle. Replaced the motor and everything is right with the world again!

Also, I assume I will need to pull out the sunroof and/or the headliner to get at the seal (part 8)? Yep, and you'll have to remove the panel (but not the headliner) to replace the rear seal (part 9) anyway.

Lotsa archive material on the subject or drop me an e-mail--I did a Roundel column on this several years ago.

cheers

I've found SuperGlue GEL (thicker than the regular superglue) works GREAT. I adhered the seal about 3" at a time, held it til it set up - then moved to the next 3" section.

FWIW: BMW sold it's own sunroof seal adhesive - and guess what? It was Superglue!!! (no kidding!)

Open the sunroof an inch or two....unhook the upholstered interior panel from the metal sunroof at the front edge (spring clips) - slide it back, while the steel panel stays stationary - then you can access the fasteners that hold the steel roof panel on, after you close it completely. DON'T try to pull the white panel into the car - you'll trash it severely!

Free your mind of all time restrictions, and focus completely on the task at hand. If you rush it - you might make a big/messy/expensive mistake. I used masking tape on the neighboring paintwork to protect it while applying the glue.

OH!....And ONE MORE tip: use a spray bottle with water in it on the painted surface of the sunroof, then apply a layer of saran wrap on it before opening it after you've installed it while you dial in the adjustment. This will buy you a little paint protection in case you're off by a micromillimeter.

HTH!

Great tips Paul - thanks - I know some dislike the sunroofs because of the rust issues they create with the drains but there's nothing like a ride on a sunny fall day (like today) with the roof open...

Hey Paul, do you know where I can get good info like this but for my E30? It happens that my headliner is all saggy and I need to attach it (Where can I get the Superglue in gel form?).

Also, I get water inside when it rains. Can these be adjusted in some way? The back side of the sunroof (when viewed from the outside) does not align flush to the roof. The sunroof is short about a 1/4" to be completely flush to the roof.

Thanks in advance!

I was replacing my seal rather than installing a new one. It is scary that I am now re-doing jobs that I did 15 years ago when I restored the car because they have worn out from use and age. Originally I used Wurth Rubber Glue contact cement but I decided to try that new-fangled SuperGlue Gel this time.

 

I cleaned off the old glue with alcohol, Goof Off, and then Prep-All but could not get all the way down to paint. There was still a line of dark adhesive residue. The Superglue Gel would not stick to this at all so I dug out my can of Wurth Rubber Glue and it worked just fine. I like that you can apply it to the entire surface and the seal and then just carefully stick the seal into place. It does yellow so you must be very careful not to get it on the visible areas. I did use the Superglue to seal the ends of the furry P channel.

My rear seal "blew out" on The Vintage trip this year.  The front edge near the middle of the seal has opened up, exposing the white rubbery cord within the seal.  Will need to get together with you, Jim, for the R&R IF it is available!

Victor  Try blowing out the sunroof drains with compressed air both ways until they are clear. You shouldnt be getting water even if the panel isnt aligned well

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
