Hi all -

Looking for some advice. My new to me 2002/2003 Toga is being put back together, and the oil coolers were sent out for overhaul.

The oil coolers are Stewart Warner, which has since been bought by Meggitt. Apparently they have the world's most special vernatherms, and a replacement vernatherm is $2K, and apparently I need one. Most other aviation vernatherms are in the $300 range. (BTW, same ones used in non-aviation applications are typically $50 or less)

Is it likely that a standard Lycoming vernatherm would fit my SW coolers? Is there a way to check? Would I be better off trying to "upgrade" to newer coolers that use standard vernatherms? Any other thoughts?

I just hate the idea of paying through the nose for a part that I know is not worth that much, even by aviation standards!

Thanks in advance.
Kris

For those of you asking, what the heck is a vernatherm - it is a temperature controlled valve that will open at a certain temperature. When the oil is hot enough, the vernatherm opens to let it flow through the cooler. This is also why newer oil coolers don't require winterization plates.
