Oil Cooler Fittings

[Ezzie]

I have leaky OEM oil cooler lines on my 2WD 1995 6.5TD Sierra 3500 Dually. I want to upgrade the cooler (Long H7A) and re-plumb it with -10AN fittings and ss braided hose. Does anyone have the part#'s and where to get the adapters that will screw into the engine block to do this conversion?

Thanks, that's exactly what I needed to know. According to this, the inlet/outlet from the block is 3/8" NPT so a 90 degree adapter to the -AN fitting is needed at the engine end.

I would crawl under there first and look. I put in new lines and had trouble fitting a 90 degree fitting in due to the exhaust manifold. Just make sure it fits. I tried to use a street elbow which is bigger so you might be ok, but I would take a look first.
