Heater hose for Dash Heater ruptured

Had the heater hose for the dashboard heater rupture and lost all radiator fluid coming back from Arizona. Got the hose repaired by splicing in a new piece for about a foot at the engine end which is on top of the engine at the back accessed from under the bed and easy to get to.. Diesel repair guy said hose was pretty hard and should be replaced. wow, its a 2008, well, has anyone had this problem and replaced the hose. not sure where it goes but will contact a shop to see if they can do it. Always something. Was lucky we had a diesel shop nearby to the off ramp and pullout. Mel

Just like on cars and trucks, Checking belts and hoses is routine maintenance safety inspection when doing oil changes. Sounds like someone did not do their job.

Engine end ; of the out to heater line; takes the full heat so it will go first. I've looked at mine and they run through a box in the frame with a plastic lid ; snaps off ; going to be a long job , have to empty the basement to open things up , the heater and A/C lines are both in there so I cant see just trying to drag the hoses through by spicing new to old and pulling, too many things to snag on. Coolant flush and hoses on the list for this summer.

Mel- your situation is much like Tom Anteau's in this AquaHot hose rupture thread. It appears WRV may have been using sub standard hose (mine is Goodyear heater hose but gotta be their cheapest grade) toward the end.
The Aquahot hose is the same hose type as used for the heater.

Mel are you sure it was the Dash Heater hose and not the Aqua Hot Hose they run parallel to one another and are the same type on hose. Read the link that EM put in his reply and Gates Green Stripe is far superior to the OEM hose. If you find out it was really the Dash Heater hose, I'll get nervous, I had two Aqua Hot breaks before changing the entire hose. However changing the whole Dash Heat hose will involve a lot more effort. Please let me know what you find out.

Tom- I don't think Mel has Aqua Hot. My heater hose is the same material as the AHot hose so I'm still thinking WRV was using old & cheap hose at the end for both functions.

You are lucky! We have a 1999 Winnebago with an SCS Frigette heating system!!

Heater cores in Winnebagos don't last much more than 2 years!! We are now on our 6th heater core!!

yes I do have aqua hot but it dumped the radiator fluid which took about 4 gallons to fill so figure it was the heater hose and that is what the mechanic said also. thanks for all the help guys. Mel
