How can I tell if my radiator has an engine oil cooler or not?

how many lines going into the radiator?or you can look under it,where the oil filter is.if you see to metal lines on the oil filter housing going to the radiator,then you do have the EOC.if you have an engine oil cooler,there will be 4 lines going into the radiator.2 on each side.if no engine oil cooler,then only 2 lines are going to the radiator.that is the difference,between the 2 radiators!
