XDP Duramax Radiator Coolant Drain Pipe XD328

Great product and simple install. The other guy's review where he says to drill a hole to drain before you cut works out nice and easy with minimal mess. His review should come as instructions in the box. Every Duramax should have this!

A must have when you are draining your coolant. This should have been factory.

This drain assembly made my life a whole lot easier, no more pulling off the lower radiator hose and trying to catch 4 gallons of coolant, just splice it right into your lower radiator hose and you're done. A quick way to do this is to drill or cut a 1/4" hole at the bottom of the hose and then shove a barbed 1/4" hose connector into the hole and let the coolant all drain into a 5-gallon bucket. Then using a razor blade or hose/PVC cutters, cut the hose right where you made the hole and slip this bad boy in with the two clamps and tighten it up, add the coolant back into the reservoir and you're done. Thanks again XDP for making such a nice part, the adapter is made from machined aluminum and anodized black. The 1/4 turn drain is chrome plated and seems to be of good quality. I added a plug at the bottom of my drain just to be on the safe side.
