Dodge Repair: removal of oil pan, silicone rubber gaskets, negative battery cable

Question
hello, my husband has been trying to remove the oil pan on a 1996 dodge intrepid and he has been having a hard time doing so. He has bought a bunch of tools but there is a bar blocking the removal please help. Also when his car is in idle or a stop the air conditoner cuts off but when he is moving it goes back to cool. I notice the other day some white smoke coming from the vents please help with this because I am not afraid to drive with him. whe the car goes into idle the car temperature goes to red and looks to be over heating but no smoke.
