Coolant side pipework 6V92Ta .....

[MagnaBill]

As part of the check valve rework the chance came to inspect the coolant pipes under the exhaust manifolds.

They were very rusty. They were originally chromed steel.

I have pulled all four pipes in total off each motor. Two about a foot long under each exhaust manifold and two "elbows" on the front top corner of each exhaust manifold.

They need replacement. Is it ok to replace these in 316 stainless steel?

They should last much longer Im hoping. I would hope electrolysis is not an issue. The coolant I run is distilled water + inhibitors. Never freezes here.

Any advice would be greatly appreciated.

Regards, Bill.

SS would be a great idea!

Would be my choice as well.

I replaced some salt water piping that Detroit used heavy copper for with the same. I figured the fact that it lasted 50 years was good enough for me as I'm sure I won't own it when the second one fails.

Yes the copper on the saltwater side is good stuff - on mine, which is thirty years old, it's holding up fine.

The pipes I'm replacing are the freshwater coolant side - sounds like using stainless hasn't set off any alarm bells with anyone so I'll go with that.

I genuinely appreciate the assembled wisdom of this forum.

Thank you, Bill.

If the steel is 30 years old and not leaking replace with same when it leaks.
