Does this stuff work? I put a bottle in my car and haven't seen any difference in coolant temps? I know there are plenty of products out there with high claims and low results, did I just pick up one?

What was your results? Or what have you heard about this stuff?

If this stuff isn't doing anything, I'm wondering if I should even keep this in the car or flush my coolant?

It doesn't really do anything unless you replace some of your coolant with distilled water along with it. Water has a lot more heat capacity and is therefore a better cooler than Glycol, so unless you really need the low freezing point where you live, you can drop your coolant temps by dropping some of the coolant out and refilling with distilled water. At that point water wetter does help, although it is mostly the water that is making the difference.

I put a bit less than a gallon of water + water wetter on my cooling system and it did help. I'd say my car runs about 10F cooler.

Water wetter improves your cooling because it makes your water more "liquid". But the additional amount of cooling it provides is next to nothing. Just another gimmick that takes money out of your pocket and puts it into someone else's pocket.

Are you running stock radiator and cooling system already? Or have you made some changes to it?

Stock cooling system. My only mods were a 160F Thermostat and reprogramming the fans so they come on sooner.

Last week a giant pothole in NYC "Modded" the front of my car, so I will be installing a DeWitts radiator next, not because I need one, but because the cost difference between that and a stock radiator is 70 bucks and the DeWitts is a lot bigger.

it works the best when you flush your cooling system out and use distilled water and water weter. we have seen dramatic drops in temp on our dyno!

From what I have read....anti-freeze hurts its cooling capabilities, if you have it in your car, and I would guess...you do.
If you do not have a cooling problem.....seems you would not notice it.

So you are using water and water wetter only? And that will keep things cooler?

High content water will run cooler than a 50/50 mix however it will void any aluminum radiator manufacturers warranty due to lack of corosion inhibitor. Better cooling comes in Boxes and not Bottles

Doesn't the Water Wetter have any corrosion inhibitors in it?

According to the manufacturer it does, however we have no way to test that claim. I question that 8 oz of additive mixed with three gallons of water would provide the same protection as a quality 50/50 mix. I also believe that the engineers at Prestone, Zerex, Havoline, etc, have built in similar packages into their product. Some race tracks do not allow coolant and in that case, you do what you have to do, and I would use it for that situation. But for everyday use it doesn't really have a purpose.
