![]() ![]() If you are JUST adding Water Wetter just add it in the overflow catch can cold and then do the De-Airing Procedure as outlined in the Service Manual.įor tracked cars in hot climates and in the summer in Northern climes I recommend dropping the ratio of Coolant/H2O from 50/50 to 30/70 and adding 2 bottles of the Water Wetter. The Water Wetter does work better with the older style green coolant but will also help the new orange Dex-Cool to a lesser extent. (You do not have to advertise the fact that you added it either.be smart.) It is a surfactant that lowers the surface tension of H2O and prevents hot spots in the engine and enhances cooling.Īdding Red Line Water Wetter will NOT void the warranty. I recommend Red Line Water Wetter, especially if you track the car. YMMV, but be sure to read the instructions on the label of your anti-freeze and follow manufacturer recommendations. If you want more cooling, and you're not worried about freeze-up in cold weather, you can go as high as 70/30 water to anti-freeze, depending on the anti-freeze, and still get better boiling point and corrosion protection. I'll see what I can find out on that.įor most cars, the best compromise is a 50/50 mix of anti-freeze and water, with a bottle of Water Wetter added for good measure. It's possible that it already reduces the surface tension of the mixture, thus minimizing the impact that Water Wetter might have. Adding water wetter helps increase the boiling point of the water, adds anti-corrosion protection, and helps the water work most efficiently.Īll that said, I'm not that familiar with the properties of DexCool. Some tracks require cars to run only water in their engines, in case a hose lets go. One of the problems with anti-freeze as well is that it is very, very slick when it's on the ground. Water Wetter also contains anti-corrosion additives, like anti-freeze. Water Wetter reduces the surface tension of the liquid, allowing it to maintain contact with the surfaces in the engine and, most importantly, in the tubing in the radiator, to optimize the heat transfer between the liquid and the metal surfaces of the radiator and engine block. When there is a gap between the coolant and the walls, heat transfer is greatly reduced. This causes the liquid to detach from the walls of the tubing. So where does Water Wetter come in? Any liquid flowing through a system is subject to turbulance. ![]() The anti-freeze protects against freezing, boiling and corrosion. So, the compromise - some combination of water and anti-freeze. The other advantage of anti-freeze is that it provides anti-corrosives that protect the metal in the engine. But running pure anti-freeze will not cool the car as well as water does. It has a much higher boiling point then water. It doesn't freeze until it gets really, really cold (way below freezing for water). But Anti-freeze has two properties that make it good for cars. Not good things for cars.Īnti-freeze (usually a glycol compound) does not transfer heat as well as water. The other problem with water is that it is corrosive. You can increase that temperature somewhat by adding pressure (the pressure cap on your system), but it still boils at a relatively low temperature. The problem with water is that it boils at 212 deg. Water alone will transfer more heat faster than anti-freeze will. Some basics - water is the most efficient coolant you can use in your engine. Water Wetter works by reducing the surface tension of the water/coolant mixture. I 've used it in a number of older cars, including several Jaguar XKE's I've owned, and it definitely reduces operating temperature. ![]() Recorded in track use and heavy-duty street use.

All this information is on bottle.ĭynomometer tests performed by Malcolm Garrett I ran it with no ill effect in my 96 GS, but because I ran antifreeze in a 50/50 mix, the temp drop was predicted to be faily small. ![]() It's intended puropose is for cars running water only. From what I recall, the temperature drop is reduced by increasing concentration of anitfreeze. ![]()
