Hi Kelly,
First, let me say that I don't necessarily have a clear idea of how the
thermostat is set up. But, if it's open (cold) why doesn't the oil get
bypassed regardless of which direction it's flowing?
My mental picutre of how it works is there is there is a hole between
the input and output. When the oil gets hot it causes something to
expand that seales the hole.

Bob & Bob,
Oil cooler threads are all 18 mm........Not sure how reverse flow will effect thermostat
operation........Even when oil is cold (less than 150 f) thermostat open, about 10 % of oil still flows through the cooler........Reverse flow will make all the oil from the engine
flow all the way through the cooler (further cooling it) before contacting the thermostat and actuating it........May not be a problem except in a cold climate where it could retard warmup or not let oil reach desired operating temp at all.........FWIW
