    RE: '15 Mustang GT Premium with PP has three way water inlet tube Motorcraft # BR3Z-18663-A. Review Coolant Leak 5.0L DOHC-2015 Ford F-150 Mustang. Coolant leak caused by a heater outlet hose becoming disconnected at the heater outlet tube on the coolant pump. Refer to WSM 303-01 service procedure for repair@ 1.2 hours. Build date on 11/20/2014 and through 1/26/2015. ford.oemdtc,com/907coolant-leak-5-0l-dohc-2015-ford-f-150-mustang. This article supersedes TSP-15-0073. Please use this as a answer to my first response. I snapped the throttle the first time with the Roush 727 hp SC kit and blew the heater hose off this tube.


    I have a '15 Mustang GT Premium with PP: Heater (outlet) hose connects to a three way tube at the front of the motor. Someone already mention the tube paint is blistering. I just returned from a Ford dealership with a new tube. Mortorcraft #KT-44, BR3Z-18663-A. Question: How do you get the white hose end connector lock clips to stay put. Super glue? The lock clip holds the hose connector but, slides up and down the tube. I snap the throttle watched the leak after burping the antifreeze and monitoring the digital head temp of 201 to 205 F. This temp is a little higher than normal do to the 727 hp Roush Supercharger kit I installed.


    Is this part compatible for a 2004 Ford Mustang 3.9 liter?


    • The Ford Heater Hose Tube Assembly is specifically designed for the 15-18 GT, Ecoboost, and V6 Mustangs. It will not work with a 3.9L.

    This looks exactly like the one I removed from the block of my 2013 GT. I can't locate one for 13-14 years, but given the motor is the same, I'd expect a nice fit. Can you confirm? I plan to replace it, because while installing my supercharger, I found this pipe to have paint blistering throughout the inside and flaking paint around both ends.


    • Unfortunately I cannot guarantee fitment for any other year range besides the 2015-2017 Mustangs.
