Cooling System Additive

Mopar to ya said
I just wanted to add that straight water runs hotter. You aren't adding antifreeze, you are adding coolant and lubricants. Lubricants reduce friction, so I understand you wanting to add them, but I would recommend a 50/50 mix of water and coolant to optimize your cooling.

Also, you are going to want to add antifreeze to it in the winter, right? Unless your car lives in a climate controlled garage, you really want antifreeze in there! Nothing like a frozen, cracked block to really ruin your day.
