Just did mine front to back Jeff’s crew did great job, Take it to Jeff’s to have it done it takes marine grade hoses , it is not that hard to do but takes time and they can be hard to get to

I think the degree of difficulty varies from converter to converter and in some cases it is really helpful to have access from below the coach and also may involve disassembly of some of the bays.

The hoses for some parts of the engine can be difficult, but almost all are reasonably accessible. Some of the hoses installed by converters are behind panels inside the coach, some are never considered, such as on my coach the coolant hoses to bay heaters or the HW tank. Who has them come immediately to mind?

It is almost like a game of hide and seek because from my experience hoses are everywhere, including behind the dash (Prevost installed) as well as at all the various heat exchangers. Changing hoses is such a big deal I usually plan on doing it when I am draining the coolant system anyway for a coolant change, and when I have plenty of time to do the extensive search required to find them all.

You guys make this sound like a walk in the park. Tell me how you will access the hoses that run through the channel, center of the bus from rear to front?

My fault Tom I replaced the ones from the motor and webasto to just in front of drive tires going into water bay those were not that bad my fault for saying from front to back sorry buddy

I’m not aware of any coolant hoses that run front to rear through the conduits, however if there are any it is likely you can join both with a connector and then use the old one to pull the new one through. It has been my experience to see copper tubing run front to rear with flexible hoses at each end. Obviously the copper does not need to be replaced.

It is going to vary based on who did the conversion, but the challenge is less replacing the hoses compared to finding the hoses.

So guys, if the are no leaks is there a real need to replace the hoses. Anyone know of a time requirement to replace the hoses?

I can give you two personal examples of why it is best to be proactive in changing hoses.

On my previous coaches I had one short section of hose that joined two copper pipes start leaking. It was only visible from beneath the coach. I saw the coolant drip, not enough to show as a loss of coolant, but just a drip that I thought might have been a clamp issue. Turns out the section of hose looked perfect righ up until I tried to get the screw driver on the clamp. The entire hose has rotted and disintegrated and just a slight movement of it was enough for it to let coolant pour from it.

The second thing that convinced me was an elbow coming from the Webasto. It looked like it had been over inflated, and in fact it was also on the verge of failing.

So I try to get my hoses changed every ten years. The last thing I need is a burst hose, sudden loss of coolant and time spent on the shoulder waiting for the tow truck. Water on board can be used to keep you going, but how are you going to get some of the places under the coach that have the potential to leak. Heat and age are the enemy.

Thanks to all that responded to my question. I’ll pass along your wisdom to my Buddy and let his make the call.

Thanks again, Larry
