How many anti-freeze hoses run to the back

[dspowers]

My 1982 Holiday Rambler dropped rear drive shaft and wrapped two high presure hoses around it. one hose was by passed but the other had anti freeze coming from it. I see two hoses running from the heater core in the front that got cut and leaks but I cannot find where the other high preasure hose connected. I have a gas-electric refrig a gas stove & ice maker cant figure out what the anti freeze line went too.

Could you have a rear heater core for the coach?

Second the idea of a automotive-type heater in the rear of your coach. Our '83 Winnebego had one installed under the bed, where the coolant circulated to warm the rear while driving.

Some coaches have a heater hose going to the water-heater as well, I believe.

It may also go to the hot water heater. My 88 winnie has an atwood wh that uses the engine coolant to heat the water while driving so you have hw when you arrive. It's called Motoraid. The same lines from the engine fed the wh and a rear heater.

I have checked every inch under coach and replace hoses that were leaking and let engine run 5-10 min and dont see any leaks, could this mean the hose was by passed with fluid in it? I have a heater blower under the bed that two hoses from the front run to coming from heater core in the front. Where else could a heater core be? Should I drive with heater running? How else can I find missing hose?

Three possibilities.
1. Hose to the front heat exchanger for dashboard heat.. you have that one.
2. Bedroom heater... that too
3. Heat exchanger on the Hot water heater. This provides hot water (potable not antifreeze) at the faucets after the engine warms up.. See if the hoses with antifreeze go into the water heater compartment. (If you have hot water before you run the water heater you have this system)

hope this helps

Since I have an HR, too, I would like to know more about how this happened. I crawled under mine to take a look (ripped a perfectly good shirt in the process) to see what hoses could possibly get wrapped up in a drive shaft. I can only locate two hoses and both of those go to the rear heater; input and output. There is a switch on the instrument panel that open and closes the valve for the coolant to flow to the rear heater. Have you tried flipping that switch to see if that makes the water flow?

[dspowers]

Thanks and sorry about the shirt. Yes mines is the same as your two hoses front to back, yes I flipped the switch on the dash and the water seemed to flow I only let it run for 5 min to see if air gets warm and it did. These hoses run to a blower under bed. No sign of leaks with idle motor I will drive short distance and see what happens.
