This one's a five-pot diesel, the lines are attached to the oil filter housing. Cooler is aluminum, including the fittings... the fittings at the filter require a thin 24MM open end to secure the brass in the housing. All in all a fiddly job. Had to cut the nut on the bottom of a shock damper to remove it, along with the left engine mount and jack the engine up about three inches.
The whole thing would qualify as a: "Don't try this trick at home"!
