I dont think there is anything wrong with the factory oil cooler.
Given its placement in the cooling system, it should keep engine oil at the same temperature as the coolant, maybe even a few degrees cooler.
Of course, without a oil temperature gauge, we will never know.
I agree!
The oil is being cooled by the coolant right after it leaves the water pump so the oil will be cooled to within a few degrees of whatever the water pump suction / radiator outlet temperature is.
I would be very curious as to what the temperature of the water pump suction/radiator outlet temperature is.
We know the coolant entering the radiator is maintained at ~180 degrees by the OEM thermostat.
Knowing the outlet temperature of radiator would tell us the differential cooling efficiency of the radiator...
