Need some help here. I’ve got an older SB2 motor, cast iron block with aluminum heads. I’m having an issue with either electrolysis or corrosion attacking anodized aluminum components in the water system. I’ve got a closed system, 16 gallon water tank. I’ve used Redline Water Wetter in the past and it seems like it doesn’t help much.
If it is corrosion in the aluminum parts, should I use distilled water as coolant, or use a little soluble oil in water, or use anti-freeze in water?
If it’s electrolysis, I don’t know what to do.
Thanks,
John Weatherwax
