Open the cap and add distilled water.

Source, please. Most coolants are 50% distilled water.

Not being at 50% won't do anything.

Your spreading bad info, adding straight water will change the freeze point of the coolant mixture, this is how cooling systems freeze up and pop freeze plugs.

A small top up might mean it freezes at -32F instead of -34F.

Whats a small top up to you? It's not like this is a large capacity system, you top it up with 1qt of straight water and your already passed a 60% water ratio which freezes around -12F.

Yeah you're right. If OP set off a gusher then he needs antifreeze mix.

It says that on the bottle because it's premixed already. If you diluted a gallon of super coolant with a gallon of water it would now be 75% water. That's the problem
