I tend to differ, Townsend - if it is as good as they say it is, the benefits are realised immediately.
As opposed to water-based coolants, the Evans Waterless Coolant adjacent to the cylinder walls remains liquid, thus more thermally conductive, meaning it is drawing heat away from that area more efficiently, potentially increasing the life of the moving parts.
In a silicate based ethyl glycol coolant, the silicates fall out of suspension and accumulate around the water pump seals, increasing chance of failure, and the water-borne particles have an abrasive effect on the impeller.
Add to this the benefit of the lower pressure in the coolant system, no chance of boiling over, and the dramatically decreased corrosion (if at all?) and it makes me wonder why it's not used in the factory, prior to delivery....
It is (apparently) a single use item - for the life of the machine.
The claimed benefits seem to outweigh cost - even if it is $100 to change, it is the only time you'll have to do it, and (apparently) has the reduced potential for coolant system failure (lower pressure, no accumulation of corroded particles, better thermal conductivity etc)
I have sent emails to Oz distributors to see pricing of that, and the Prep Fluid so will report back.
Just think about it, if the claims be true (and Jay Leno doesn't seem to be one to endorse a product without reason, especially with his motor vehicles) - a fill with
this stuff will be the LAST TIME YOU HAVE TO SERVICE THE COOLING SYSTEM, for the life of the vehicle.
Sounds good to me!
