Installed in Jeep Wrangler JK as my steering fluid cooler. The hose included in the kit is the perfect size to fit the return line in the tank. I routed rubber hoses to the radiator that fit perfectly behind the grill and in front of the radiator. Doesn't affect the radiator in any way, but my steering fluid doesn't boil hot from the 4x4. It also increased my steering fluid level (Jeep JK uses ATF for steering) by another 1.6 liters.
