radiator fluid change

Going to drain radiator fluid by removing the bottom radiator hose. any one know how much fluid left in the engine? and how do you get it out? a shop mechanic says he has used the water pump to bring it out but I think that could possibly burn up the pump. I know there are flush systems at auto stores , but my coach is a 05 southwind and the dog house is screwed and siliconed down.
I changed the fluid about 5 years ago by just draining the radiator and then filling it up again with new fluid. Thanks for any thoughts...

On each side of the engine is a bolt, cant remember the size, but you can either use a wrench or it made to accept a hex key.

You would be surprised the amount of coolant that comes out.

search the site for 8.1 coolant change I know I have seen a thread or too on this.

I just changed mine last month


I found the size of the bolt/hex The block drain plugs are 17MM. The hex socket is half inch drive

The way I've always changed coolant is to drain the system, fill it with distilled water and run it several miles or days.

Then I drain it again, measuring how much comes fluid out and refill with a 50/50 mix.
