You are lucky that a fire did not start.

Indeed. Perhaps it failed under pressure when the pump was activated rather than while driving? However it happened this has me considering a fire suppression system for the engine compartment sooner rather than later.

I have had a fire suppressor in my coach since I bought it, also my previous Alpine. I had a friend of mine lose his coach in about 25 minutes from a hydraulic hose that broke while climbing a grade in hot weather and dumped it on the exhaust.

Update as of today, Monday.

I’ve learned a couple things in this repair;
-4” D clamps to connect the turbo to the exhaust duct cost $40 at Napa.
-The small flexible hydraulic lines for room slides and such use fittings that actually screw onto the end of the high pressure hoses. So yo can replace them yourself.
-A 6’2” and 220lb 55 year old man can slither his way horizontally into the engine bay and replace the missing 4” D clamp. Just be sure someone is around to pull you out by your ankles if necessary.
-Don’t keep your tools in a hydraulically operated storage drawer because if you lose hydraulic power you have no tools...
-A good friend is priceless on a Sunday when your coach is having issues.

Yes we are back up and running. Some of the membrane on the underside of the coach melted/blew away due to the hot exhaust being directed forward under the coach so I’ll need to coat the area with Flexseal I think.
Thanks very much to all who chimed in and offered help.

PS--with a modest amount of effort--did you know the entire bedroom floor between the bed and the rear closet on an 07 [40ft], can be removed for access to the engine compartment? Not sure if that would haver helped in your case but cant imagine trying to crawl into the engine compartment, rather than remove floor...

Great name. Thanks for the tips. The 3rd one reminds me of a friend who lived in a townhouse with a garage below where he parked his car. The only way in or out of the garage was through the garage door equipped with an electric door opener, no pedestrian door from the exterior or interior. All units were the same. One morning there was a power outage.

I didn’t fully understand how the hose failed
Would you explain in more detail the nature of the broken hose?
Was it a fitting that broke or came off the end of the hose?

Also, is a hose clamp used with the screw in type fittings?

Bob, the fitting hangs below the coach floor underneath. When the exhaust duct from the turbo to the muffler came loose and dropped to the side all that hot exhaust blew forward and heated up everything in its path. The fitting was likely very hot when I stopped and tried to open the bedroom slide. The pressure easily popped the hose out of the screw in fitting since the hard rubber/plastic outer coating that the threads hold on to were in a molten state at this point. No clamp will help hold this design. I am thankful it was easily remedied after some study of the lines and fitting because there was no way I could find to easily get to the other end of the line where it attaches to the cylinder. Old Scout mentions the floor can be removed but from my experience there is a lot more involved than that. I disassembled my bed down to the frame and didn’t even see the floor yet. Access to the top of the engine is done through the step in front of the wardrobe on my coach. No getting that step top off when the bed slide doesn’t move out... prove me wrong.

That was my goal but without the bedroom slide moved out that was not going to happen.

Just a thought. If you ever do any interior renovations it might be worth the effort to modify the step so it is in 2 sections with a seam that lines up with the slide in the retracted position.
