Oil Coolers Reduce Oil Temperature for Longer Engine Life
You will need to find a hydraulic hose shop to get a right angle fitting (2) that has a 1/2 inch smooth nipple for a push on hose.with a 1/2 inch inside diameter. You may need to go to Home Depot to get reduction fittings for a 1/2 inch inside diameter hose connected to a 3/8 inch inside diameter hose. This cooler is heavy duty for large vehicles so you may want to buy a cooler with smaller 3/8 inch diameter connects suitable for either oil or transmission fluid.
