Same goes to the Outlet hose with the T joint using a conncetor which you can buy at your auto parts store, 3/4 inch size.

The heater core is on the back side of the firewall. It has 2 hoses of 1/2 inch diameter running into it. It is about in the center of the firewall. Take the 2 hoses off the firewall. Get a hose with good pressure and back flush the heater core by running the hose into the side with the long hose on it. If you are not sure which side to do then do it both ways.
