Wrong coolant possible cause of the common Dt466 cylinder liner leaks?
My Dt466 had leaking cylinder liner seals. Its repaired but I did some investigating. You hear lots of stuff about cavitation but this was not the cause of the leaks. It was due to hardened, cracked and possibly shrunken cylinder liner seals. What would cause that? Over heating? Possibly. But I started to dig into ELC and HOAT and OAT coolants. These are said to be hard on seals. I think using the traditional green antifreeze with a SCA additive may be the best solution. Or a Diesel antifreeze with the SCA in it. What are your thoughts?
