This Dorman heater hose fitting links the hose and pipe that carry engine coolant toward the heater. Over time a connector at this joint can crack, break or begin to seep. Coolant dripping or crusted residue at the heater hose connection, or a coolant level that keeps dropping, are signs this part may need replacing. If a failed connector is the source of the leak, this direct-fit replacement for the listed applications replaces it. Consult the vehicle service information for the correct procedure to drain, refill and bleed the cooling system.
