@pthomas745, I know that feeling too!  I'll probably wait till the weather here cools down just a bit before I dive back in but I'll post what I find!

@glesieutre, when I totally rebuilt my heating system in my 2015 I was able to purchase numerous 90 degree pre-molded bends from Truma/Alde, that may no longer be the case.  If you can't find those you can try plastic molded forms used for PEX piping (Lowes, Home Depot, etc).  Or if you like to geek out like me you can warm PVC pipe, bend it to the angle you want and let it harden then cut the inside of the bend off so you can slip the hose into the saddle which will now support the sides of the hose and prevent the crimping.

Thanks @barbarella20722, this has been an eye opener and an in depth look at a daunting project that a 400 owner may face. It would be helpful, if you haven't done so already, to mention the name of the miracle paint you decided to use.

I now have all the convectors removed except the one under the wetbath. I coated the stubs with the miracle paint and will leave them to dry overnight. 


The passenger side was easy. The hose was too long, pushing down on the stub. I may have to cut some off the end so everything fits properly. I'll see how it all looks first.


The center top was attached with pocket screws from the inside and you can't remove it in one piece because the wires are screwed to the back face. So I did what I had to. That's all I'll say about that.



The hose on one side wasn't quite "straight on". So it needed cleaning. 

 The front hoses had a surprising amount of glycol still in them and it made a bit of a mess. I'm seriously thinking about putting another low point drain up front. IF I'm able to find a suitable location. Tomorrow I'll slowly start putting things back together and figuring out a couple access panels so I can keep a better eye on things.

  It's a big, messy job, but it's not hard. Now if something went bad on the actual Alde unit. That's probably something I'd nope out on. Hopefully these pictures will help other 400 owners that may run into this issue in the future. 

I'm going to try and post pictures as I go to make things a little easier for me. 






To get to this I had to remove the fabric board and the plywood piece behind that. I backed out the pocket screws (Roberts head again). Removed the two, 2" Phillips screws that I assume went into the frame. The convector and wiring harness are screwed in from the back. You'll need some kind of low profile ratcheting tool to get these out.

I happened to have this already. It did work, but barley. Quite a bit of glycol did come out from the front hose. So try to put what towels you can under it. 




Pieces I've had to remove so far, JUST to get to the convectors.🤨
