cavitation coolant addatives

[MikePA]

From Expert Diesel. Did a Google on 'cavitation'. /forums/images/graemlins/smile.gif

Constant vibration of the cylinder liner causes a momentary vacuum to form on its surface. Coolant boils into the vacuum and vapor bubbles implode on the surfaces of the liner, digging into unprotected liners. Cause pits which can extend over time, through the thickness of the liner and allow coolant to enter the combustion chamber or crankcase. The Supplemental Coolant Additive coats the liner with a thin film to protect it from erosion without impeding heat transfer.

I would only add that damage is not limited to wet-sleeve designs. Parent-bore blocks are prone to cavitation erosion as well. I don't believe I have ever heard of or seen damage to a dry-sleeved block, but I wouldn't want to own the first one to have a problem.

Thanks for the information.This is a new area for me ,I'll have to do some more investigating on this. It sounds to me like this additive should be used year round and not only in the winter. From reading Soundguys post I took it that it was some kind of winter coolant tune up at first /forums/images/graemlins/smile.gif Goes to show you learn something new everyday.

Just for clarity, I stated that I was changing my coolant. When i do / did this.. i lost all of my treated coolant. When i refilled with untreaded coolant, I needed to add the addative back.

Some units that have coolant filters have the option for pre-charged filters.. etc.

Also.. this addative protects against electrolysis as well.
