Switching to Evans
The drier is between the overflow tank and the T with the radiator.
The theory behind Evans is that their formulation of straight glycol will transfer heat from the cast iron through nucleate boiling without pressure. To some degree this happens in regular systems too. It's important to keep those small bubbles from coalescing and turning into steam pockets. In contrast the various water-glycol mixes use pressure to help control boiling. Ironicly, Chrysler and some others ran the cooling systems at atmospheric pressure, with a cap that would build pressure only when needed.
Back when they had started and they only had one formulation they sold an inline drier as part of the installation package. Even starting from a fresh block, it was used and the system ran at atmospheric pressure system. I used Evans for about two years. The final straw was when I had to put a new radiator in at the track. The incident had nothing to do with Evan's product. Replacing that coolant on short notice was the final straw. But I was glad to be done with that experiment.
