We hear about preventing engine cavitation in the cooling system of Cummins and other wet sleeve engines, but what are the signs of cavitation...how does one know there is a problem?

Steve said:My experience with most service technicians I have encountered is few have a clear understanding of the correct procedure to test DCA. I have been testing my own since acquiring the coach, and change the anti freeze using OEM Cummins Compleat low silicate antifreeze precharged with DCA.
Many motorhome owners have not tested their cooing systems because dealers frequently don't bother explaining the procedure and since most service techs don't know how to do it correctly, I suspect there are many coaches displaying the effects of cavitation.

You are lucky to have a newer coach and engine, but older rigs were not equipped with filters that took care of their needs. There are a lot of older rigs with new engines at less than 100,000 miles that are victims of cavitation.

I concede the point? However, outside of replacing the cylinder liners, I know of no repair for cavitation, so knowing that you have it doesn't help much. Prevention is the best cure.

? ? ? I don't think there is any real symptoms except excessive pinging or pre-ignition.? And of course, all diesels rely on compression ignition, so it's difficult to know the difference.? You will sure know when it has occurred because you will have coolant in your oil.? At that point, you have an engine re-build facing you.

Can you explain me how chemicals can prevent this to happen?
