Jeff,

I can't remember who it was that had the same = problem=20 with two oil coolers.

I believe the oil and oil cooling are mostly=20 independent, but not totally.

Perhaps you can use the two for oil cooling on = extended=20 climbs/ Take-off, and shut one off at cruise?

You didn't mention the actual temps of = both oil and=20 water, was this flight temps or just running the engine?
