- Install: It is recommended to use a heater hose disconnect tool to remove the old connector from the firewall. When installing the new fitting it will be a tight fit by design, it is recommended to use some soapy water to help slide the new fitting onto the heater core tube and make sure to keep pushing it until you hear or feel a "click". Be sure to clean all the crud off the heater core tubes before installing the new fitting. Secure the heater hose with the included clamp.
