go to autozone.com. and click on the heater core part for your sonoma. then there should be an install manual button u click on on the page. i have a 98 gmc wit a heater core out also. i think the 97 models you just have to take off the dash.
the heater core is located behind the dash on the passenger side of the cab. much of the dash has to be removed and shifted to get to the box that houses the heater core. the hoses that supply coolant to the heater core must be remove via the engine bay. it is somewhat of a lengthy process, but can be done with patience and time.
It is inside the heater core box behind the dash assembly. The dash assembly must be removed to gain access.
The nipple next to the heater core hoses is the drain tube for the a/c . The antifreeze is coming from the heater core , that is leaking .
I had the same problem with my 97 galant. There was air in the heater core.
Disconnect the negative battery cable.Drain and recycle the engine coolant.Disconnect the heater core hoses using tool J-37097 or equivalent.Remove the right side sound insulator and the glove box module.Remove the programmer shield, if equipped, and disconnect the air mix valve link.Disconnect the programmer vacuum and electrical connectors.Remove the heater core cover, leaving the programmer attached.Remove the heater core retaining screws and the heater core.
You will have to disconnect the liquid line and the accumulator from the evaporator tubes in order to remove the heater core.....
