getting rid of a/c

[Jeff Chambers]

Those black tubes running along the lower manifold on the passenger's side are your heater core hoses. You can pull them out if you don't want heat any more. The one that screws in to the lower intake can come out and the hole plugged with an NPT plug. The one going to the water pump can be pulled off too then. The hose stub on the water pump can be removed and the water pump body tapped for an NPT plug as well. Some people will just put a large rubber vacuum cap over the WP stub, but I've seen those crack and break over time so be very careful if you go this route. When you pull the AC condenser box from behind the dashboard, the two firewall fittings will come out with the box. You can make a nice aluminum block-off plate to cover the hole in the firewall and rivet it in place.

Thanks for the help. I think I might keep the heater core just incase I wake up on a cold morning and find my windows frosted. Is there a book out there that shows you custom modifications like removing the a/c? Cause when I was removing the upper manifold, some tiny hoses came off and I have no idea where they go. I'm thinking that they might plug into the bottom of the lower manifold. I was hoping that I could find a book out there that shows where this lines go. Thanks for all the help that you have given me so far. When I get ready to install the damper I hope it won't be too much of a hinderance if I ask you for some tips when the time comes.

Sorry to hijack thread, but if the manifold is plugged, what do you do about the sensor thats screwed into the pipe? The small black hoses are vacuum lines. Probably PCV and evaporative emmisions canister.
