The 2006-2016 Duramax trucks don’t have a coolant petcock to drain the coolant, you have to disconnect the lower radiator hose making a HUGE mess! Eliminate the hassle of servicing your cooling system with our new DmaxStore Coolant Drain Adapter. Our adapter will keep things clean and controlled during routine maintenance.  Our stainless steel drain plug makes draining the coolant system a breeze.

This adapter is easy to install, simply cut the lower radiator hose, and after cutting simply install our adapter and tighten down the included clamps to complete the installation.

Don’t get caught up in a mess of coolant.
