Heater Core Supply Hose Flow Restrictor V8 1979-1993

Product Description

Heater Core Supply Hose Flow Restrictor for all 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992 and 1993 V8 Mustangs.

The Heater Core Supply Hose Flow Restrictor is an important part to check when you are replacing your heater supply hose or checking the heater core's integrity and performing maintenance on your 1979-1993 V8 Mustang. 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.

Rated 5 out of 5 by from Cost Effection Solution for Other Vehicles Too! My 1999 Chevrolet S10 pickup was missing the OEM flow reducer in the 3/4 inch dia. heater core supply hose. I could not find any aftermarket replacements at the auto parts stores. This part fits and works perfectly.

Product Questions

I have a 79 Mustang, 302 engine. I have been reading about needing a flow restrictor in the supply line. Is that true? Which line on the heater core is the supply, small or larger (from water pump or from near thermostat)?

Asked by: dhuffy01
The supply is from the intake from behind the thermostat, the return is to the water pump.
