Not knowing what part of the wourld you're in or how cold it is, but what works good is disconnect the heater hoses from the engine(not the heater core) and use a regular garden hose. Or, you can use an air hose, blow it out, add some water to the hoses and blow it out again. You can do this several times, BUT, --you have to be careful with air so you don't blow up the heater core. On adding freon, if you buy a 134 recharge kit, it will come with instructions. Most important is to be sure you are on the correct hose for charging.
