3/4" Heater Core Supply Hose for 1986-1993 Mustangs with a 5.0L Engine.
There are three hoses and a metal coolant tube that push coolant to/from the heater core. This hose is located towards the driver side on the firewall and it connects to the bottom of the heater pipe. It is a good idea to replace this preformed hose if doing work with the heater core. Markings on the hose help ease the installation. You will see a perfect fit as the hose is an exact reproduction of the original.
A flow restrictor is included with this hose. The restrictor limits the pressure going to the heater core to reduce heater core damage and leaks.
