Ive got no heat in my 91 sunbird. Ive changed the heater core thinking that it was blocked. One side, 1/2 size is hot the other 5/8 sive is cold. On both cores.

Do you

The heater hose, when the engine comes up to operating temperature both should be hot to touch if the coolant is passing thru w/o obstruction
