what could cause a vacuum in the radiator on my 1995 lincoln? I also have coolant running out the exhaust pipe when it is running

Sure it is coolant and not condensation during warm-up? If it is coolant you have a bad head gasket...

A little water running from your tail pipe when the car is cold is normal. When you burn gasoline you get two things - CO2 and water.
A vacuum in the radiator is a bad radiator cap that is not letting coolant run back into the radiator from the reservoir when the car cools off.
When I said water I mean the whole radiator will dump out if you keep on running the engine. The vacuum is like if you have the radiator cap off and place your hand over the opening it will pull the radiator hose flat
