This is recommended for all 1979-1993 V8 Mustangs to reduce heater core leaks because complete core replacements are extensive and expensive jobs.
This part is a great pick up to help prevent future problems with the heater core in your Mustang. This restrictor fits directly in the hose leading in to the heater core. This will inhibit the amount of coolant that is allowed to move into the heater core. It narrows and restricts the pathway to reduce the volume and pressure which will help prevent heater core blow outs and leaks.
Original equipment on 1996-2004 4.6L Mustang and was also originally used in police cars and 1993 Cobras, this heater hose restrictor can also be used on all 1979-1993 V8 Mustangs as well. This part helps reduce the risk of your heater core failing during use with its ability to decrease the pressure of the coolant that flows into the heater core. It easily fits inside the heater core hose and comes with installation instructions to make the replacement process even easier.
*Because of its slightly longer length, the use of light grease may be required to fully insert the restrictor in to the 1979-1995 Mustang's heater hoses.
