Change Tyranny Fluid through cooler lines?

[Ernzo]

I am sure that I read here long ago that you can change, or at least re-new tyranny fluid by dropping the input line to the radiator and letting the pump run the fluid out. This would be done carefully and new fluid would be added at the same time. Anyone done this? Which is the in and which is the out? I *think* it is passengers side out, which would be the one to drop.

Hmmm mm???

I did that once when I changed out the radiator. After I thought it was hooked up I cranked up the engine and started pumping fluid all over the driveway. So yes I had to add fresh fluid.

Sorry I don't remember which side I forgot to hook up.
