I have been thinking about adding water wetter to my coolant. Has any one tried the stuff? Is it any good, or just a waste of money? Does any one know how it works?

 

I use it. I believe the stuff works. I used it in a previous car that had heat issues and it brought the temps down. I put it my C6 about a week after I got it, so I don't know impact.

 

The chemicals in Water Wetter allow the water molocules to bond to the metal surfaces in a more efficient manner, thus transferring heat to the liquid faster. If you use antifreeze in your coolant, you will not see much of an improvement. They recommend using distilled water for the best results. Water Wetter and distilled water will drop your coolant temps 20 degrees, but, without rust and corossion inhibitors found in the antifreeze, personally, I think it's risky. Want lower coolant temps? Use a 160 t'stat, and reprogram the cooling fans.

 

Do a search. It has been discussed MANY times.

 

Save your money. Won't do a thing unless you run a higher water to anti-freeze mix.

 

From what I know its mostly recommended for track use...for cars that may overheat and boil-over. Anti-freeze leaked onto the track surface is slicker than oil and it can be almost invisible....very dangerous to those running on the track.

IMO unless you're running on a track and prone to over-heating and in the absence of any other cooling issues, I would not use it.

 

I added two bottles and my temps dropped!

 

Yes, it definately works. I use it in my vette and my bike. The less antifreeze you have mixed in, the better it works. In my vette I've kept the dexcool around 30% of the mixture. If you're just cruising around town, there's no point. The thermostat will regulate the temp for you.

 

160' thermostat=181 to 183 normal cruise. OK 2 bottles red line water wetter, it breakes down tensile strengh of the water, after 2 bottles I got ZERO change in temps. DOES IT WORK????? you tell me. save your money then again it might work for you .

 

They are surfactants that modify the surface tension of liquids. It is a well known scientific principle that works.
By altering surface tension propoerties, a more complete contact is made with the metal and more heat is exchanged.

Both my C4 and C5 have reduced temperatures by at least 10 degress usung watter wetter.
I picked up my 08 this fall and will add water wetter before the summer.

 

Save your money. Did absolutely nothing for me. Got a bottle to put into my sons GTO. Gonna do it for the heck of it because I already bought it.

 

In addition to the 2 bottles of Water Wetter, I drained the coolant and refilled so I'm at 15-20% vice 50%. That's OK for VA Bch but not for IL.

With the 60 deg stat I run 175-185 in 90 deg wex.

 

That's why I mentioned that there's no point if you're just cruising around town, or even at the drag strip, since those runs are so short. It cools more efficiently, but the temp won't drop because the thermostat will close to keep the temp at the setpoint. When the cooling system is working below 100% duty cycle, more efficient cooling won't change the operating temp. Water wetter will then just lower the percentage of the duty cycle the system is functioning at. It basically just increases the total cooling capacity, like having a slightly larger radiator.

At a trackday, when the thermostat is wide open, but you're putting out so much heat, that the temp is hovering at 225, that is where you see the lower temps. Under those conditions, the thermostat is wide open, yet there's not enough cooling to keep it at 180 (or whatever your setup stays at). Meaning, you're at 100% duty cycle and still can't get temp to the setpoint. With water wetter (and less antifreeze) the increased efficiency means it can transfer more heat under those same conditions. So you'll be running at 215 instead of 225. (These are just example numbers)

On my motorcycle, it's a bit different. The thermostat there allows a small amount of water to flow when it's fully closed. Because of that, I get temps lower than the setpoint just cruising on the freeway on a cool day. That used to not happen unless it was 50 or below. Now that happens when it's as warm as 70.

 

Being in South Florida it was necessary for me.

 

Did nothing for my C4 or C5. Save your $$$$

 

I have always used Water Wetter in all my cars. The Water Wetter has never reduced the operating temp of any of the cars that I had, because I use coolant. Water Wetter temp reduction should happen if you use only water in your cooling system, according to Red Line. I use Water Wetter only for the corrosion protection...two bottles for the Vette.

 

I've used it in my other car. I've been told by an engine builder never to use it. This was when they were installing a cool stat and Koyo aluminum radiator (other car).
