How to change heater hose (connector that connects into heatercoil)?

When changing my heater hose(lower radiator hose) i noticed that the connector type fitting that sticks out of the firewall of my car is cracked in half and that was were it was leaking. how do i change that piece. i tried unscrewing it but that didnt work. i tried giong thru the dashboard floor area and only get stuck with things that i can't remove. i can not put the hose back on until i have the small piece replaced. someone said it is connected into the heater coil? behind the fire wall?

No it isn't behind the F/W.



You already removed the clamp on the rubber hose????



If so get a razor blade and slit the hose starting at the firewall and going away from it for about 2.4 inches. Then take a screw driver and gently work it into the slit you cut and get the hose to release off the heater core pipe. Be carefull the heater core is brass or aluminum and deforms/crushes really easy then you are screwed. Heater hose is available by the foot(price) and custom cut for what ever you aske from a 50-100 foot roll. Take the old one to the parts store with you and get two new clamps,do not reuse the factory ones(they suck).



Good Luck

To avoid having to replace the heater core under the dash, try an epoxy type repair. For a metal pipe, use the Permatex product below. They may also have an epoxy for non-metal materials.
