Since I'm replacing my water pump soon and have to drain the coolant anyway, I figured it'd be a good time to install the block heater I've had sitting around forever.. Its a ZeroStart tank style. What size is the thread on the block drain? The ZeroStart Mercedes adapter is insanely priced (more than I paid for the heater (which includes a 1/4NPT adapter)) There must be somewhere I can get an adapter that converts whatever the drain plug is to 1/4NPT...
