Yes, No, Idont no and will it hurt anything?

 

Reading between the lines here, I don't see any need to run WW in your truck unless it runs real hot for some strange reason. A 50/50 anti-freeze is all you should need.

 

I tried this stuff in an old Ford Ranger I had back in the 80's. Absolutely did NOT work as advertised... Just my opinion/experience, though.

 

It works well if your using straight water, like in drag racing. If your running an antifreeze mix like most everyone on the street then your wasting your money if you think WW will help reduce temps.

 

Water Wetter is a great product, but as said, it's probably not really needed for your truck. It's made for race cars/bikes so that when they crash it doesn't muck up the track like anti-freeze does. I ran it in my 2001 RC51 Racebike and it worked great. If you do use it, make sure you get Distilled or at least Reverse Osmosis purified water in conjunction. Well, you should use that with anti-freeze too, but anyway... It won't hurt anything if you do use it, but I doubt that you'll notice any difference in how cool the engine runs. Cheers!

 

I was considering it in my RFS KTM 520 which does run hot and the guy at the parts store thought it "really worked" so I was considering it in the truck.
