[Healeys] Antifreeze

[Steve B. Gerow]

Chris,
You must be changing your coolant often enough for the pH to not get too low.

I experienced more corrosion in the last couple of years with water wetter and purified water compared to the previous 8 years with coolant/purified water which was essentially nil. There were enough flakes of rust clogging the radiator tubes to make the car run noticeably hotter.

While the rad was out for service, I did a back flush of the block with water in through the lower water pump hose attachment and put a woman's stocking on the upper hose fitting as a filter. 2 or 3 tablespoons of crud showed up in the stocking along with some more rust bits.

There's a lot of info online in various hotrod forums on how water wetter is no longer being developed; it can result in a peanut-butter-like goo in the coolant; the chemist who developed it no longer works for Redline, etc.

These same folks prefer Royal Purple Ice instead of water wetter because it is evidently a more modern formulation. I was all set to add that to my coolant except it would have required 2 bottles at $15 each so I said the hell with that and just went to the coolant/tap water mix with an Australian Tefba coolant filter for good measure.
