144 inch sleeper blu4 heater hose replacement

I have on my Volvo. It's not biggie. Just get good quality clamps from a dealer

 

No, but at some stage I’ll need to.

Tedious job, I would over wrap anywhere the brackets are, and any rub points. You’ll have to dig out the insulation where it comes up into the hot water heater and reseal.

Consider replacing the hot water unit while you’re at it.

 

Thats silicone line comes in a roll, lowes has stainless clamps

 

I did this recently on mine after I blew one of the hoses back to my APU right in the middle of I40 in Charlotte. It wasn't a fun night. I was able to cap the system, refill the engine side with water and get to my destination.

I just replaced with high quality heater hose but did have to buy like 40' of it. I figured if it happened once I better replace every inch of it.

After the fix I added some 6" sections of aluminum tubing and clamps to my tool box. If I ever have a blowout like that again I can patch it and roll on, at least if I have enough coolant/water on board.

This is a messy job but not awful.

 

My worry is why would you have holes in the lines in the first place?

Are they chafing or just too old?

a good quality hose is what you need, Goodyear makes a hose that I use, hy-miler.

 

That is one interesting looking sleeper. Who built it?

 

I recently replaced all of the heater hoses in my truck along with the bunk heater hose. I used the blue silicone hose because I see it being used alot and figured it is the latest and greatest thing and last longer. If I had to do it over again I would go back to rubber heater hose. The silicone doesn't seem to seal good at the connections for me no matter what clamps I use and there is nothing I hate more than the smell of coolant. After digging into it a bit I find others with the same problem as me. Just my experience with it.

 

That silicone line is crap IMO. Could never get it to seal either. I prefer the Goodyear blue Hi-Miler hose myself.

 

I've replumbed several of my school buses with silicone hoses. When the bus dissolves there will be nothing but blue hoses sitting on the ground. Have to use the double wrap spring loaded clamps. Once a year I tweak all the clamps. The blue hi miler hose is good as well. A little less temperamental..
Any hose made with EPDM rubber is miles ahead of cheap hose.
