Waterless Coolant systems...Good or Bad?

More hp and torque amplifies this. Also watch close and you will see the piston pressing against the wall of the sleeve on the power stroke. Now imagine big torque and low rpm push on the side of that sleeve with a mid stop liner that doesn’t have enough clamping force from the head because Cummins sets liner height at .010 instead of Rawze recommended .014. That extra .04 is a lot of extra clamp force keeping that liner from dancing around on that shim. Once that liner starts dancing around it’s game over. Looses head gasket and doomed for perpetual rebuild every 30k or so until someone actually does the job right. Most shops are like there all at .010 but one is .09. It’s good. Build it. They don’t realize that .09 isn’t flat anymore and it won’t hold. It’s frustrating to watch people do this. Maybe this animation will help other situations on a different topic.

Proper coolant and radiator pressure fight against the bubbles forming and if they do the coolant additives protect the metal from the bubbles bursting and blasting the liner. So I would think that running a weaker coolant with no pressure would be like diluting our oil with mineral oil then running a lower oil pressure. Not a good idea

I would love to know how someone ever figured this out??????? There's no way to ever see it happen with your own eyes.
