1. I disconnect the hose that comes out of the radiator.
2. Blow compressed air into the press. tank to get all the coolant out.
3. I fill in as much water as I can and blow it through also.
4. put the hose back on the rad.
5. disconnect the to hose on the H pipe, and turn it upward, the clamp off
it.
6. plug the H pipe where the hose was.
7. install a hose into that hose, that will be taller than the rad. top.
8. fill the system with 2 gallon of undiluted coolant at the press. tank
9. put the cap on when no more goes in there
10. carry on filling the system with water until it comes out at the
radiator.
11. close the rad. valve
12. pinch the hose at the H pipe
13. take off the long hose and connect the hose to the H pipe back, pinch
off, clamps back.
14. run the engine 2000 and keep filling while it's cold
15. put cap back on, Finished.

Subject: what coolant flush method is best

I'm wanting to do a coolant drain and fill on my 85 and was wondering if
there is a latest and greatest method for  one man (along with reluctant
wife) to do a drain and fill without jacking up van and runnng front to back
to open and close valves or drains. I would take it to a service shop but
don't know who can service a Vangon here in the Chicago area. Thanks for any
help.
