134a is a type of refrigerant; yours probably started out with R12, but that has been pretty much outlawed at this point (R12 is apparently toxic but it also tended to be a much colder charge making it seem to be a more effective A/C system). Just pick up a manual and go the A/C section, start removing pipes and you're all better. It will clean up the engine bay tremendously and since the condenser won't be in front of the radiator (assumption based on most other cars) it should allow better flow to the cooling system.
