  Replaced Windows on MKIII and Marsolved the A4 (jboyle)

Hello from Annapolis -

Thanks to the inspiration found on this site, I just replaced my plexiglass windows on my 1976 MKIII.  It was so simple that I am kicking myself for not doing it sooner. 

It is not necessary to remove the aluminum frames.  The windows come out of the frames from the outside by removing the old gasket.  You then clean the frame with a scraper and acetone, and use the old windows as templates for new ones.

Then you replace a little sponge gasket with a sticky side to the aluminum frame.  Install the new plexiglass and push the gasket in between the frame and the window.  Simple once you know how.  I ordered the gaskets from southshore marine (about $120US for both gaskets for all 4 windows - plus installation instructions) and had a local shop make the windows.

I also tried Marsolve in my trusty A4.  It had been running hotter and hotter in the last few years.  So I bought some at www.mermaidmarine.com (about $29 plus $15 shipping to Maryland).  It works great - First I flushed the engine with fresh water both from the exhaust side and the waterpump side.  Then I ran the Marsolve into the system just like I was winterizing - but first removeng the thermostat and clamping off the bypass hose.   I left it in for about 2 hours and the fired up the engine to run it out.  It now runs about 25 degrees cooler.

The bad news is that when I was running the motor under load (in the slip) I discovered a leak in the water inlet manifold.  It has been leaking for a while judging from the rust.  So the next chore is to replace that gasket. 

I will keep you posted.  But don't go another season with those milky white opaque windows - it's an easy job to replace them.

Hi Joe (and others).

Sounds like you learned a bit-- thanks for sharing. For those with 'opaque' windows and little enthusiasm to change them, here's a temporary fix-- Toothpaste is a very mild form of rubbing compound and if one does both sides of the windows with toothpaste and a soft cloth, much of the opaque film ( I suppose it's oxidization) will polish off. This fix might last one seasaon before fogging again.

Joe:

Thank you for the windows update. I hope you don't mind, but I immediately swiped a portion of your post as an addition to the Windows section of Black Arts. Prior to this, everyone has said that the frames do have to come out and that's the sort of additional complexity that makes people shy away from a very rewarding job ('hard work pays off tomorrow – procrastination pays off immediately').

As to replacing the gasket, note the recommendation in Tools and Spare Parts for 3M Spray Penetrant as a superior product for loosening stiff fasteners.

Black Arts was very valuable in recent window replace.   I'm Toronto based and used Plastic World to cut new plexi.   Took a bit of fine tuning with dremel, but all fit fine.    I gave them old ones as template. Price roughly 200 so inflation has made its mark relative to prior Black Arts quote.

I have the "glue in, screw in" type.  On some other recommendations I used Dow 795 sealant.   Was easy to work with and stayed pliant for some time to fine tune.  

Thanks to this site

Yup, replacing the gaskets on all four of my windows was really a piece of cake.  Took some practice not to stretch either the seal or the gaskets, but the effort was really worth the effort.
