Napa Kool additive

[b11lefevre]

Is this comparable to the motorcraft additive or is it junk?

Well you can't go wrong with napa products.

Usually, except the alternator I got last week. Glad I had tools so I could take it right back off and ask for one that actually worked.

what about Redline products "Water wetter" I use this in my mustang and can tell a great differance in the temps .

Good call Mako, it's in my mustang too. Now I fell dumb, after going to Redline's website it sounds like it would work. I know it's great for lowering temps, it's the only reason my head gaskets are still alive. After blowing 3 of them I figured that 10 bucks for the stuff might be worth it. Weird 500rwhp+stock radiator on a supercharged 5.0=blown head gasket, never would have imagined!

a friend of mine that worked at petty enterprises said they used to run that crap in the qualifying cars. I figured it had to be pretty good stuff
