does this stuff work?

 

From my personal experience a little, but it is only a band-aid fix if you are having cooling problems.

 

im curious, how much does that stuff cost? And it won't increase coolant pressure enough to cause leaks will it?

 

about 8 bucks a bottle

 

No, What it does is decrease the surface tension of the coolant. This makes the boundary layer between the coolant and the radiator smaller, allowing greater heat transfer. It doesn't affect pressure at all.

Whether or not it is useful on a street car is another question. If the cooling system is working properly then the thermostat controls the temperature pretty well. Mazda has the thermostat set at 180*F, making the car run between 188*F and 200*F. RedLine Water-wetter might cool it off to run around 185*F to 195*F. That's hardly noticable on the stock gauge.

If for some reason your car isn't controlled by the thermostat (either its disabled like on a race car, or the system is running marginally) then the water-wetter might help more. However, like pillage6 said, if your system is running marginally this might help but is only a bandaid -- you should be looking for the source of the overheating.

 

have you ever looked at all the crap on the shielves of most auto parts stores ?? tons of **** !! water wetter is one more , of a long list of adititives in one way there isn't any system on a car that you can't add something too. but, it's made by redline, so it's respectable.

 

I do not see any real advantage using WW for street applications.

It real use if when racing because most sactioning bodies ban the use of coolant- glycol base products on the race track. Due to their very slippery properties when leaked out of a car.

WW helps keep the engine temperature down, but has no anti-rust inhibitors so you need to remove it after the weekend racing is over. Or buy Prestone Anti-rust additive and add that to the radiator too.
