This stuff is going on my list. ThanksSpeaking of engine cooling, one of my first mods will be to replace the engine coolant with a product like Evans Waterless Coolant. It provides superior engine cooling by raising the boiling point to a level (275°) that doesn't boil (or pressurize) the cooling system in normal service. By making the coolant more efficient, you ensure you don't have engine heating problems in traffic. As a bonus, it prevents corrosion (no water) and still lubricates the water pump. Prices begin around $40/gallon, but because it never requires replacement, it's good for the life of my Elio.
