My Bluestar project is advancing and I am at the point I want to add the coolant.     This van has the rear heater removed and the two hoses are connected in an open bypass.

I am wondering if this is a good idea.   I am not planning on reinstalling the rear heater any time soon.   I would have thought that it would be better if the two rear heater hoses were plugged off rather than connected as the free flowing by-pass could short change hot coolant going to the front heater.

If I am to make a change, now would be the time to do it.  

Any opinions?  Experiences?

Thanks, Steve
