[keltymd]

Anyone running VP Cool Down in their Whipple coolant or radiator? Any negative effects?

Tried water wetter in main rad and water pump seals started weeping half way thru season of tracking. Changed water pump and run 1/2 gal deionized distilled with balance 50/50 predilute motircraft.
IC I run Zerex 50/50 predilute no additives just so I can tell any diff between leaks via diff color.
Some additive might cause precipitates if you dont have more water than 50/50.
Pump seal lub properties and head gasket material properties general keep me favoring very close to 50/50 motorcraft for motor and Zerex for IC.

I do 80/20 in both rad and HE. I've tried water wetter and the Royal purple. No negative effects, but if they do anything it's to the exact same degree. My guess is it's a gimmick and. You will get more from the water/coolant ratio.
