Red Line 80204 WaterWetter Super Coolant - 12 Ounce (2 Pack)

This should be an automatic addition to every hot rod cooling system.

I’ve used this stuff for years and it definitely help coolants to stay cooler longer.

The first time I used this was at the race track. I put it in per the recommended dosage and it did everything the salesman said it would. That was in 1993 and I still use it in all my cars.

This stuff worked great on my classic car. Runs nice and cool now and no worries about overheating.

Works great. Apologises to seller I made a mistake on sellers review.

As advertised and just what I needed

Most of these water wetter type products do work. This one i can for sure vouch for as can most racers ect. who actually have acurate gauges

According to HP Tuners scanner, during highway cruising (not consistent, but as the coldest recorded coolant temperature; went down from 192 deg Fahrenheit to 190 deg Fahrenheit). Of course the 2 degrees of better cooling was only established after the water wetter. Mind you, I had factory thermostat, 09 SIERRA 2500HD 6 liter engine, 50/50 DEX-COOL premixed. Each car is different.So not so much of a change, but hey, it made a difference. That being said, I believe now it takes the engine a little more time to heat to operating temperature. This may be good or bad depending on your weather. I live in a very hot climate overseas which easily reaches 120+ Fahrenheit so anything helps.If you want better results, you can add drinking water and coolant. I don’t like to do that because drinking water contains minerals which may or may not harm the block. If you choose to do that, I advise you flush your coolant more often.Is it worth it? For me, I am happy even though it’s only 2 degrees difference, but in the Car World, every digit counts in my opinion especially that my test was accurate enough and represents real-world test.Good luck!
