@jerrysr posted:that's another reason why I wanted to maintain a cap in the smaller tank. To "mostly fill through then too off through the larger tank.
I DID too! But, using a long thin flex tube funnel, AND two people I know the system (4 Gallons) can be filled going through the gap between open deck. for the three days I have car back, I have used a 10" dowel to check the lever. I can't recall exactly but my expansion (big tank) is 6" higher than top of swirl (small tank).
Jerry, my drawing depikes the tanks after modifications are made, thus my large tank had multiple barbs put on side. My naritive gave instructions for techs to fabricate
Bell, do you expect a cold volume of air in the big tank, or do you have a third reserve tank for the large tank to suck back coolant as cooling.
its been a while (and I doubt if I can do it now) but my 6" higher is to allow the expanding coolant to compress the captured air AND no spill from large tank (with radiator cap) I might have an illustraion of the expected pressure rise verses diffent large tank elevations. if intersted (but I wont be able to explain)
