  1. To check the system for refrigerant, feel suction line (3) and discharge line (4). The discharge line runs to the condenser that is located near the radiator.

    If the system contains refrigerant, the discharge line (4) will be warmer than the suction line (3) .

    If the system does not contain refrigerant or the system is very low on refrigerant, poor cooling will result.

  1. Close the engine hood.
