A/C Line or Hose Replacement This guide requires the following supplies: Refrigerant oil Safety Tip: Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes. 1 Open the hood and locate the vehicle's A/C lines or hoses. Photo may not be specific to your vehicle 2 Disconnect the negative battery cable using an open ended wrench. Photo may not be specific to your vehicle 3 Recover any refrigerant (discharge A/C system) with an A/C machine. 4 Remove damaged A/C lines or hoses. Photo may not be specific to your vehicle 5 Install the new o-rings, A/C line, and hose. 6 Reconnect negative battery cable. 7 Evacuate all remaining A/C refrigerant using an A/C machine to pull a vacuum on the system. 8 Recharge the A/C system with the A/C refrigerant and have the A/C system leak tested. Each vehicle takes a different amount of A/C re...

Air Conditioner Working Of Automotive Air Conditioner System How A/C Works In Car Helpful Information Hoses and components should be checked for deterioration, bubbles, cracks and hardening or oily residue, all could be signs of leakage. Leaking Condenser Proper refrigerant levels should always be maintained, low system refrigerant charge is a common cause of a weak AC system. Odors can developed in the air conditioning system when a fungus has grown on the evaporator core, aerosol disinfectants can be used to remedy this condition. Refrigerant charging kits are available at many auto parts stores. Leaves and dust particles can get logged in the condenser hindering its performance, use a garden hose or compressed air to clean. (Note: An air conditioning system is under pressure, until the system is discharged completely, no repairs or disassembly should be performed. Eye protection should always be worn.) Easy to understand guide on how an automotive air condition...

Air Conditioner Recharge CAR A/C RE-CHARGE Helpful Information There are two separate occasions that an air conditioner system needs to be recharged. The first is a normal condition of residual seepage where a simple recharge of refrigerant is needed. The second occasion is when an AC repair has been performed such as replacing a leaky compressor, condenser or evaporator. Once the system has been opened it must be held under vacuum for a period of time (usually 30 minutes) to remove moisture that was allowed into the system when normal atmosphere enters in place of the Freon (refrigerant). Car air conditioner systems have a mixture of refrigerant and oil to keep the air conditioning compressor lubricated and operating properly. If repairs involve replacing the compressor or any other major components such as the evaporator or condenser system oil must be considered. Though measuring the (peg) oil (synthetic) is difficult because its spread throughout the system an estimat...
