Once the cooler is bolted up, all that remains is to slip the hose ends over the barbs on the cooler and fasten the clamps. B&M warns not to double-clamp any connections. Conveniently, we were able to route the lower hose under the radiator support and the upper hose through an existing hole, but we got lucky. You may need to create appropriate holes--don't force the hoses under, over, or through anything that may pinch or chaff them for obvious reasons. Remember, this stuff will be vibrating, if only slightly, but frequently.
