Mustang Heater Core Flow Restrictor
The heater core flow restrictor is an important part of the replacement of your heater supply hose and heater core on your 1979-2004 Mustang. This part helps reduce the risk of your heater core failing. The flow restrictor's job is to decrease the pressure of the coolant that flows into the heater core. It installs in the 3/4" heater supply hose in all applications. On the heater core side of the hose, slide the tapered end of the restrictor in first. No extra clamps are required for installation. This heater hose restrictor is original equipment for 1996-04 Mustangs, but can also be used on 1979-95 Mustangs as well.
