Heater Core Box Reassembly
Is there a grommet that goes over that hole at the above the vacuum canister? Or does that stay open like that? I realize a rubber line will come out of it to connect to a vacuum tube.
 Also, for the door that that vacuum canister actuates, I can only adjust it to seal at one extremity of the vacuum canister's range or the other, but not both. Should I bias it to seal in heater mode (vacuum applied to yellow tube) or NOT heater mode (vacuum applied to white tube)? The pontiac assembly manual doesn't appear to clarify. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
