This project seemed appropriate with the weather getting colder.
I tore into the factory BN4 heater. After cleaning out the accumulation of soot, rust, mud daubers, and possibly some asbestos... I set to work cleaning things up for reassembly.
Good thing I had a few spares for parts, the safety switch wouldnít shut off, and the gear that drives the points which in turn pulse the fuel pump was stripped. (Future 3D printing job for overhauling these with new printed gears I think?) The control relay was sketchy too, and worked intermittently when tapped on its side.
After cleaning up the rust, painting it, reassembly and addressing some connector issues, I did a crude bench test, checking fuel pump rate, time before glowplug shut off, output temperature, cool down time, safety switch operation. The factory manual helped demystify any questions I had about these, and they really are quite safe. As safe as the condition of your fuel line I would say.
With our last Ď74 Westfalia I ditched the factory heater, but this time figured it may come in useful for camping in slightly cooler conditions. Yes I know there are Chinesium diesel Espar knockoffs on Amazon etc, but wanted to keep this install a bit cleaner and original. Some pics from along the way.
First test run before temp switch adjustment, pretty toasty

The new front seat covers arrived this week. Custom made by J Luis Alvarez, using the original VW plaid material. Nobody locally could even touch his prices & craftsmanship. Looking forward to overhauling these seats.
A wise person once told me, ďAlways spend a bit more on things that keep you off the ground, whether shoes, mattress, tires, etcĒ
Good advice, plus they cost the same as the cheapo aftermarket seat covers every other VW parts vendor sells.
Now I need to decide on using new cocoa fibre pads or foam. I am leaning towards the cocoa fibres, as Iíve used foam in the past and didnít care for the overstuffed puffy look, and they seemed pretty hot in the summer. Would be interested in hearing from anyone with practical experience using either...
New vs 45+ year old funk
Should reupholster all the seats in the house with this 🙂
Wanted less orange, picked black to tie things together better IMHO
Contact info for the vendor. Excellent to deal with.

Damn! Those are nice covers.
The black is a slick touch.
I agree on the fibre pads, i think it will have that classic look and feel.

I finally got the camper top and new canvas back on. This was just not fun at all to install. The staples for the top tack strips were cake, getting the hinges and hardware back on, no problems.
But dicking around with those 40 or so little screws through the aluminum strips in the bottom canvas was a pain. I had to make a few V relief cuts in the corners to get things to fit right, careful not to cut into the canvas itself. I was ready for a case or two of beer after the last corner. My back, shoulders and hands are still sore a couple days later.
Iím thankful I wasnít doing this in the heat of summer. Also having the upper bunk removed made things easier, canít imagine trying to do that with the bunk in there?
The canvas is the one made for Bus Depot. Iím happy with the quality and fit of it, time will tell how it holds up. This didnít have any canvas when I bought it, so itís an automatic improvement.
