This is a Genuine Mitsubishi coolant pipe that goes from the water pump around the back of the G54B to the heater hose in your Mitsubishi Starion or Chrysler Conquest

Some early applications had a bypass pipe with an extra port on the front for your turbo coolant line. If you have that style coolant pipe you’ll need to upgrade your water pump with the extra water port on the water neck. It is the water pump I have available here. The pipe with the extra port is no longer available.
