Water heater engine hoses

[tom geiger]

So was working on installing the iso pads today and ran into the hoses that ran from the engine to the water heater. Had to drop the brackets holding
the hose up to get the hoses out of the way. This brought to mind that some believe these should be eliminated because of the potential risk to the
engine if these split and ran the coolent dry. Would be best to remove these and plug these connections?

Why not just replace the hoses and enjoy the free hot water for another 10+
years? That's what I've done for the past 20.

Ken is correct.
The hose that run that circuit holds up very well and serves a good
function,
Should one tries to replace the hose, be sure to pull the new hose by
attaching it to the old, otherwise it is hard to pull through on the GM
models.

So I'm thinking you are saying to attach and pull new hose at the point it enters into the coach somewhere under the fridge or bathroom? Simply cut
old hose and attach for the pull there?

That's the idea but it will be a bit of a chore. I'd find a couple of barbed unions to attach the new hose to so the hose diameter will be a small as
possible. You'll want to pull from the bathroom side of course...

It also helps if one person pulls in the bathroom end and someone else pushes at the same time at the other end.

I was wondering the same thing when one of mine sprung a leak last year. In a pinch, i opted to replace it via a roll I got at AutoZone, however the quality of the hose doesn’t seem as good (as thick) as the original; Though it may be possible that the original hose had “puffed up” over the years to just “look” a bit beefier... thicker?
I held off on replacing the second hose until I determined if there was a better quality readily available somewhere. (Both Oreilly and NAPA had the same type of stock as AutoZone). Has anybody investigated this further and perhaps have a good recommendation?
BTW: When the same thing happened to the Birchhaven a couple of years ago, I opted to just loop the hose up at the engine and cap off at the water heater; reason being, in my 10 years of owning the coach, the water heater rarely got even close to warm when driving... definitely never hot like the Eleganza. I never had a chance to fully investigate why this might be, (before I was distracted by more pressing concerns, Like brakes, bearings, or transmission)! Anyway, i’m happy somebody started this thread and I look forward to any recommendations, thanks!

You got the idea, lot of people have first removed the old hose and spent
hours shoving in the new.
I always discuss things, however simple with people I feel has had
experience .
There are lot of experienced owners out there and they love to assist you
On my recent trip when we lost oil pressure in San Antonio, Tx I used the
Black List and also consulted with couple guys as to plan how to possibly
repair a severed oil hose.
The first person that answered my call for assistance was Steven Hendricks.
Heck of a nice guy that came over to assist and offered to have my MH put
in his drive way.
I was glad to meet him and so was he. Told him us Asians all look alike.
With his assistance and knowing where to get parts and supply and his shop
garage large enough to house his coach and equipment, I was in Fat City.

These major stores stock good stuff as they are trying to supply repair
shops.
Your old Jose is puffed up.

Got it, thanks guys. I'll see if I can find a good hose amongst auto stores here.

Thanks again

If you are looking for better hose then ordinary heater hose get multi purpose hose Napa has it but it costs more. Most high end diesel rigs use multi
purpose hose instead of common heater hose and it's usually rated at 250 or 300 psi. This hose should last longer and be less likely to fail as it
ages.
