B&M 70266 Hi-Tek SuperCooler - 20,500 BTU Rating - 40 Row - 11in x 8in x 1.5in

I wanted an engine oil cooler for my Detroit 6.2L diesel - that wasn't in the radiator. I looked around at both product and vendor choices. I'm pleased with both. The oil cooler is quite sturdy with no thin, fins that get bent over when a fly or gnat run into them. This is tough enough it doesn't worry me to clean it with a direct blast from the pressure washer. The 1/2-inch NPT in and out meant it was easy to adapt to whatever size and type of line I wanted. I rather liked the flange on both sides for mounting. It's easy to put 2, or 3, or more screws on each side to hold it in place. It is mounted in front of the radiator, plumbed with 10AN hose (from JEGS too), and seems to be doing a good job. The manual does say the cooler should be mounted with the inlet/outlet pipes on top, or on the sides - not with both pointed straight down, which was my original plan. I'm not sure of the reason, maybe air getting trapped at the top diminishing cooling? Hopefully the folks writing the manual know their business
