Bus heaters removal or relocation

I am in process of removing this rear heater unit on my Thomas 2000 mvp-er and I found the heater shutoff valve fir coolant. There are 2 hoses which go to the front of the bus heater so I assume one is a return to the engine. Can I take these hoses apart with the valve shutoff and how much water is in the line? This is my first bus and need to get a service manual to figure some of this stuff out??any input would be appreciated!

I see that this heater is in the middle of the heater lines, so there must be another heater. If you plan on removing both heaters, then you can remove them together by shutting off the heater line valves and clamping the hose right near the cut-off valves and removing the hoses. Take the hoses and heater cores outside of the bus ad drain them into a 5 gallon bucket. The clamping (with some vice-grips) will allow you to remove the hoses from the shut-off valves with a minimum of mess.

I bought some 1” hose barbs and deleted the rear heater. I kept the heater hose loop to the dash heat and windshield defroster. The 2-1” hoses prob run back under your bus behind the drivers seat. Prob to a heater up front. This was the advise I got couple yrs ago around here. Defrost is good!

So after I shut off the heater valve, I must still standing coolant in the lines. If I drain into a bucket, should I reuse the coolant or just add fresh stuff? I am planning on changing the coolant in the radiator in about a month without driving it since I just got the bus and starting my conversion.???

Clarification: I am actually use the rear heater . Just need another 6 feet of hose to move it over and if I pinch the hose, I should be to do a quick changeout.
