Good Afternoon Welches and fellow listers,
Water Wetter is the brand name of a wetting agent for competition cooling
systems manufactured by Red Line. It should be available at most
automotive performance shops.
Temperature and wetting agents:
Adding a wetting agent to your coolant will NOT change the operating
temperature of your engine, that is controlled by the thermostat(s). The
wetting agent changes the surface tension characteristics of the coolant.
The quick example of this behavior shows when you spray water on a freshly
waxed car, the water shows on the waxed surface as beads. If you add a
little soap (a wetting agent) to the water, the water now shows on the
waxed surface as a thin, slippery film.
In your cooling system this effect is desirable because it reduces the
probability of an air bubble appearing between the coolant and surfaces
over which the coolant is passing. The coolant flows more easily,
allowing more heat to be transferred between the surface and the coolant.
In the engine this is good because the coolant can take away more heat, in
the radiator and heater cores this is also good because the heat in the
coolant is transferred more efficiently to be dissipated by the air
passing over the core.
In your Vanagon:
You will see your temperature climb faster after a cold start, or in
heavy traffic. This means that the heat being created by the engine is
being transferred to the coolant more efficiently. You will also see the
opposite: after sitting in traffic your temperature will decrease much
more rapidly when you begin moving because the radiator is able so shed
heat from the coolant more efficiently.
I have run Water Wetter for years in my Vanagon, Mercedes and Subaru. I
think that it is worth using because of the improvements realized in
cooling efficiency. I have NOT seen any change in operating temperature
of my engines under normal operating conditions, but there is a
significant change in how quickly they return to normal temperature after
being stopped in traffic.
Regards,
Jon Kanas
