Other special wrenches you will need are a spark-plug wrench and an oil-filter wrench.
You will need jumper cables for boosting your car, a continuity tester for testing electrical circuits, pliers for loosening and tightening things you can’t loosen and tighten with your wrenches, a stiff, non-wire brush for cleaning battery contacts, a utility knife for cutting rubber belts and tubes and a tire pressure gauge for checking the air pressure in your tires.
Basic Automotive Tools Every Car Owner Should Have On Hand
If you have an older car it may have R12 refrigerant in the air conditioner system. The bigger one goes on the low pressure side of the system and the refrigerant hose will only connect to the low side valve. Turn the can upside down and hook it up to the low side adapter valve. Now slowly open the valve and let the Freon flow into the system. Keep adding Freon until the system begins to cool. (Do not grab the high pressure line. If you have a air conditioning manifold gauge set, the low side should have a pressure of 40 – 50 psi.
