Buy 1 gallon of streight green antifreeze.

Buy 1 gallon of distilled water

Mix.

Not you have 2 gallons of antifreeze 50/50 mix for 1/2 the cost of the 50/50 gallons from the store.

When you pull the engine out as much as I do it doesn’t get that bad. Whenever my car is “done” I might actually use some of the forbidden Mountain Dew
