Unless your running in extreme heat or a road course. You shouldn't need it. That said, I've heard it does work. If your car is running hotter than normal, you should correct the problem first.

Do a system flush and replace with Dex and distilled water
Burp the system
Check the hoses
Buy a new pressure cap
Check for a stuck t-stat
Check to make sure the WP is working
Make sure the space between the radiator and the A/C is clean
Start with the above and get back to us.

Red- Line makes Water Wetter, Supposed to lower temps maybe 8 degrees, I have used on forced induction cars and it helped I think, But pretty hard to tell unless you have an accurate gauge and before and after testing

Problem is, if you want to run regular, green coolant in a car that has had Dex-Cool in it previously, unless you get 1000% of the Dex-Cool out FIRST, you'll have a HUGE mess in your cooling system. Those two products DO NOT mix..........
And there's nothing really wrong with Dex-Cool, as long as you maintain the fluid level in the radiator/expansion tank, and you DO change it every 5-6 years.

Dexcool was first installed in Corvettes back in '95 and it does work very well for those who want to use something like a 50K-mile or 5-year coolant change interval. There's no real reason to use a green ethlyene-glycol coolant in later GM cars. Especially if you don't do a near surgical cleaning out of the Dexcool first.
As far as using Water-Wetter, it will lower coolant temps a small amount but if a cooling system is in good condition, there's no real need to use it. I have heard that it helps with coolant flow but it has a fairly short life, maybe 6 months to a year.
I use it in my '87 autocross/track day car but only because I don't use a full 50-50 mix of anti-freeze in the summer; it's usually 5% or so. A boil-over or sudden coolant loss on a road course makes as mess as anti-freeze won't evaporate like plain water will. And anti-freeze is slippery and can remain on a track surface for extended periods if it's not cleaned up.
