Heaters, hoses and doo-dads

[JRinCali]

I've been reading the threads, old and new, and still in need of some targeted guidance. Thank you in advance for your indulgence.

1 - fresh air hoses -- mine continually get sliced where it transitions from engine compartment to the underside. I don't think the sheet metal is sharp -- just appears to be friction and heat that causes these flimsy fresh air hoses to get sliced and leak. Is something wrong in my set up? Hoping there is a longer term solution to what has become an annoying routine maintenance.

2 - Heater to Body Hose. I noticed that this transition pipe (in photo) was dangling and not doing what it was supposed to be doing. As I was in the process of getting it back in place, it occurred to me that this is really a poor connection point from the heater exchange boxes. It's not a tight seal, and for some reason the previous owner had it wrapped in this heat shield fabric type thing.


The question I have is: What is the preferred approach for these heater-to-body hoses? Is there a make/manufacturer I should be looking at?
Should the seal be tight? Are there considerations for having these hoses wrapped in some type of heat shield? A general "this is what you should do" type response would be awesome

3 - Perhaps a dumb question, but how do you know if the Heat Exchangers no longer work? Are there tell-tale signs? The reason I ask is while I'm monkeying around down there, I'd like to assess their status and replace if necessary.

Thanks much for you time and thoughts on this!

http://www.wolfsburgwest.com/cart/DetailsList.cfm?ID=028129087A West has new hoses etc.. The Heater to the body hoses would be probably something you would want to keep original if they are that solid. VW insulated them but it's not needed. I used Porsche 911 Fresh Air Aluminum Fresh Air engine hoses on my bus (Between Heater Boxes and Body) but makes it where I can hear the engine through the heaters though. Not bad.

The Black paper hose is a lot more forgiving than the Aluminum Fresh Air hose. Get the Seals that go around it. As far as connecting the coupler that you may have for a stock exhaust on the fresh air hoses. If you no longer have a stock exhaust then you can omit it and just use one piece of fresh air hose to complete the air flow to the heater boxes from the fan shroud.

The fresh air hose plugs into this:

And that pugs into muffler
I thinks (someone will correct me) these are the correct baffles for heat exchanger to body

The complete heating system for a later bus has the gray vinyl wrapping. The flexible pipe you show connected to the heater baffles are included in the wrapping.


Note there is a strap (similar to the original ones on the one piece axle boots) on both ends of the flexible tube.

Here's another picture in my ad

Nancy tells it like it is! Those stiff but bendable metal hoses are covered and "insulated" by the vinyl style covers on the later Buses, abd on earlier Buses that covering is different, looks almost like fiberglass cloth. I believe that Nancy has a nice reproduction of some of those insulating wraps...
