Need to flush the heater core and radiator. Need 5/8 to 3/4 coupling to connect garden hose to heater core hoses to flush heater core.
Need two couplings for heater core hoses...instead of removing heater core and installing new hose, get two 5/8" x 5/8" hose couplers (Dorman part number 56438). Then only need to get 3-4 feet of 5/8" hose, install couplers and replacement hose, then good to go.
Alternate part number for 5/8" x 5/8" hose coupler
