Yes...all the HD trucks I've seen have them. My 2000 2500 6.0L had an oil cooler. There's a machined spot on the block just above the oil filter with the feed and return holes in it. Cars have a block off plate there.

If you want I can get a picture of mine for you.

Edit: Redheartbeat "beat" me to it...gotta love dialup.
