1991 SUNBIRD HEATER
1991 Pontiac Sunbird
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.

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
