Heater Hose Coupling: Disconnect
WARNING: This page is about a different car, the 2003 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not attempt to install a new bushing, spacer or O-ring in the heater hose coupling; damage to the heater hose coupling can result. If the heater hose coupling is the cause of a coolant leak, the affected heater hose must be replaced as an assembly.
- Depressurize the engine cooling system.
- Push the heater hose toward the tube to fully expose the locking tabs.
- Push the special tool over the coupling retainer windows to compress the retainer locking tabs.
- Pull the heater hose away from the heater core tube.
- Spread the retainer tabs apart and slide the retainer off the tube.
- Discard the retainer.
WARNING:
The engine must be off, fully cool and the cooling system fully depressurized before attempting to disconnect any heater water hoses. Failure to comply with this warning can result in serous injury or burns from hot liquid escaping out of the engine cooling system.
NOTE:
When compressing the white coupling retainer with the special tool, the special tool must be perpendicular to and on the highest point of the coupling.
NOTE:
If the heater hose coupling is accessible, the retainer tabs can be compressed by hand to disconnect the heater hose.
NOTE:
A slight twisting motion while pulling on the heater water hose may be necessary to assist in the removal.
