[DeTomaso] Front Oil Cooler

[John Taphorn]

Perhaps you should consider eliminating the thermostat.  While a case could 
be made for the thermostat on an air/oil cooler, it strikes me as counter 
productive on a water/oil cooler.  My reasoning is that since the coolant 
heats faster than the oil, the oil cooler is actually an oil heater until 
the oil absorbs more heat energy from the engine than the coolant. 
Therefore, a benefit of the water/oil cooler is it gets your oil to 
operating temps faster.  A thermostat would not only eliminate this benefit 
and it adds a failure point.
