Eliminate the hassle of servicing the cooling system in your 2006-2019 GM 6.6L Duramax with the XDP Radiator Coolant Drain Pipe XD328. Draining the cooling system in your truck requires removal of the lower radiator hose. Once that hose is removed, you'll find yourself scrambling trying to contain the mess of over 4 gallons of coolant. While some use buckets, kiddie pools, and many other methods, none solve the real issue of trying to eliminate the mess and contain the coolant so it can be re-used or properly disposed of without splashing all over the floor of your shop, garage, or driveway. 

The XDP Radiator Coolant Drain Pipe XD328 helps you keep things clean and controlled during routine maintenance. With the included ball valve that has a 3/8" NPT drain outlet, you can drain your cooling system with just the turn of a lever. Built from CNC machined billet aluminum, the XD328 installs in-line with one easy cut through the lower factory radiator hose. Simply cut the hose, slide the XDP Radiator Coolant Drain Pipe in place, and tighten down the included T-bolt clamps to complete the installation. Each drain valve comes ready to install and is anodized black for aesthetics and corrosion resistance.
