Just thought Id give you guys a heads up if this hasn't been discovered already. Ive installed 3 Dicad Kits on my truck and a couple friends. They have both complained about leaking coolant when it gets cooler outside but I ignored since mine wasn't. I finally developed a leak after a 7 hour trip to the U.P. and I tore apart to find the rubber hose that was supplied with the coolant redirect elbow had "BBER AIR HOSE" stamped on my 4 inch section. Rubber air hose is definitely not the proper hose for that application. The hose had cracked on the bottom and became very soft and melted around the hose clamps. I replaced with heater hose and no problems. I guess you really do get what u pay for.
