I'm changing/flushing my coolant soon and I want to put in a coolant additive when I change my coolant. These hot Louisiana summers are killing my engine. These are the three most popular additives out and I was wondering which one do you guys like the best?

i have good things about water wetter, never used it though.

they all look good and from what i can see u cant go wrong.

they just recentely used the royal purple in a camaro on horsepower tv also.

 

I have used Redline in my Z and have had no problems.
