Over time, small leaks may develop within the air conditioning system. Often, these leaks are so small that it may not be necessary to replace components within the system, but rather service the system with extra refrigerant. Luckily, most do-it-yourself mechanics can service the system themselves, avoiding a trip to a professional mechanics or dealership. The system on a Ford Ranger can be serviced within a hour, using basic equipment available at most auto part stores.

Step 1

Attach the hose end of the recharge hose to the air conditioning low pressure port. The port is covered by a black dust cap, located on the top of an air conditioning refrigerant line next to the windshield washer fluid filler neck.

Step 2

Screw the can of refrigerant to the valve end of the hose.
