Hey I'm trying to remove the a/c and heater from the car How do I plug the copper lines that go to the engine or remove them completely.

 

Do that at the engine inlet (drivers side, below the oil filter pedestal) and at the radiator where the heater core line exits the radiator.

I did the same and had a radiator company braze a cap on the radiator lower hose to block that outlet. On the engine block, use a rubber bung meant for boats that seals the hole and has a screw to tighten in place, or you could braze/solder a cap over the metal pipe. Alternately, you could rig up a cut heater hose with a plug in it and hose clamps.

The two lines going to the core at the firewall can be plugged with corks or rubber stoppers to keep bugs/hornets from building nests in there, but be sure you evacuate it fully or you'll have a stinky swamp growing in there. Let it sit open for a week in dry air and it should evaporate completely.

 

I used these on the engine side for capping the water T
