Its got SOME silicate. But the thing that really drives most of the
"Diesel requirements" on coolants is the big wet-sleeve diesels which
need nitrite additives to prevent micro-boiling and cavitation damage.
Not needed for most automotive diesels at all (and WOULD be needed for
any wet-sleeve gasoline engine, were there many in mass production),
but not a bad thing to have ini a coolant since cavitation damage can
happen in any engine... it just won't eat all the way through to the
combustion chamber except in wet-sleeve designs.... or as Dan will
probably point out, early Ford 5.4 Triton cylinder heads :-)

No time to worry about Ford's garbage; I'm thinking about the wet-sleeve
aluminum 225 in my '62 Lancer.

IIRC (waiting for Dutra's article to load) yep, I was right- the Al 225
isn't a "wet sleeve" design. Its got free-standing aluminum bores, an
open deck head, and *dry* liners inside the freestanding bores, just
like almost all modern aluminum engines do. Making it a "parent bore"
engine.

True wet sleeve engines run the coolant directly on the back side of the
replaceable liner. That requires some fancier sealing at the top and
bottom of the liner, but allows for maximum heat transfer, which is why
its usually only done on BFDiesels that run at max output most of their
lives.

IOW- if you removed all of the liners from an Aluminum 225, there would
still be "cylinders" in the block. You could fill the block with coolant
and it wouldn't run out. But if you remove all the liners from a
wet-sleeve engine, there is no physical cylinder remaining at all- just
the sealing ledges at the bottom of the cylinder bank and at the block
deck. The cooling passages would be directly open to the crankcase.

Pictures and everything, but you have to tolerate a bit of blather about
how "inherently" better wet-sleeving is. Truth be told, the DT466 is
about the cut-in size for which it is a benefit. Anything smaller
doesn't really benefit as much and costs less when built as a
parent-bore engine- eg. Navistar's own T444e, Cummins B-series, etc.

Oh! Never heard the term. But I guess I get to go sit in the corner for
having failed to memorise Dutra's article ;-)

Think the Viper V10 was one of these (maybe only the gen1 engine?).

Nah, its just the photo of the top of one bore showing the liner and the
casting that I was remembering :-)

Since I can still easily find the "old green" antifreeze at my auto
parts store so that's what I bought. I bought the Canadian Tire
antifreeze that says it's good for 2 years or 40,000 kms.

I'll probably do I complete flush and fill with the G05 when I can no
longer find the old green antifreeze.

Thanks for all the input.

Mike
