so anti freeze isnt needed if you live in so cal? just water and wetter water or something of that sort?

No, not needed here in the So Cal low lands.

Car will cool better with Coolant Additive and distilled water. The JB Super Cool has more properties than just being a surfacant. The JB Super Cool has rust and acid protection.

But for a water only system you should add the JB Radiator Protectant. It has has strong anti rust properties, anti electrolysis properties, AND water pump lubricants. The JB Radiator Protectant has Metal Deviators that act as a ground bridging through the cooling system.

The pitting, holes, and scale in the small block Mopar timing chain covers is from electrolysis, acid, and cavitation. Same goes for aluminum intake water passages. The two products above help prevent that.

The problem with using dish wash as a surfacant is the other properties it has for washing dishes. And it lacks other non surfacant properties needed for cars. Also, what mixing ratio do you use? Wash you dishes with dish soap and put proven automotive grade products in your auto.
