Mariner 4WD L4-2.3L VIN Z (2005)
1. Connect an R-134a refrigerant center to the low pressure and high pressure gauge port valves following the operating instructions provided by the
equipment manufacturer.
2. Evacuate the system until the low-pressure gauge reads at least 99.4 kPa (29.5 in-Hg) of vacuum and as close to 101.1 kPa (30 in-Hg) as
possible. Continue to operate the vacuum pump for a minimum of 45 minutes.
3. Turn off the vacuum pump. Observe the low-pressure gauge for 5 minutes to make sure that the system vacuum is held. If vacuum is not held for 5
minutes, leak test the system, repair the leak and evacuate the system again.
Refrigerant System Evacuation Using an R-134a Manifold Gauge Set
NOTE:
-
Use of a refrigerant center is recommended to carry out recovery, evacuation, and charging of the refrigerant system. If a refrigerant center is not
available, refrigerant system recovery, evacuation, and charging may be accomplished using a separate recovery station, vacuum pump, charging
meter, and manifold gauge set.
-
Leaks in refrigerant system equipment, hoses or gauges can cause a leak in vacuum that may be misinterpreted as a problem with the vehicle
refrigerant system. It is necessary to leak-test all refrigerant system equipment, hoses and gauges on a weekly basis to verify that no leaks are
present.
1. Connect the R-134a manifold gauge set to the low-side and high-side gauge port valves.
2. Connect the center (yellow) hose from the manifold gauge set to the suction port on the vacuum pump.
3. Open all valves on the R-134a manifold gauge set and both gauge port valves.
4. Turn on the vacuum pump and evacuate the system until the low-pressure gauge reads at least 99.4 kPa (29.5 in-Hg) of vacuum and as close to
101.1 kPa (30 in-Hg) as possible. Continue to operate the vacuum pump for a minimum of 45 minutes.
5. Close the high-side and low-side valves on the manifold gauge set (not the gauge port valves) and turn off the vacuum pump.
6. Observe the low-pressure gauge for five minutes to make sure that the system vacuum is held. If vacuum is not held for five minutes, leak test the
system, repair the leak and evacuate the system again.
Refrigerant System Charging Using an R-134a Refrigerant Center

Leaks in refrigerant system equipment, hoses or gauges can cause a leak in vacuum that may be misinterpreted as a problem with the vehicle
refrigerant system. It is necessary to leak-test all refrigerant system equipment, hoses and gauges on a weekly basis to verify that no leaks are
present.
1. Lubricate the refrigerant system with the correct amount of clean PAG oil.
2. Connect an R-134a A/C center to the low-side and high-side gauge port valves following the operating instructions provided by the equipment
manufacturer.
3. Set the refrigerant charge amount, and charge the refrigerant system following the instructions provided by the equipment manufacturer.

1. Lubricate the refrigerant system with the correct amount of clean PAG oil.
2. Assemble the R-134a manifold gauge set, automatic refrigerant charging meter and R-134a supply tank following the automatic refrigerant
charging meter operating instructions.
3. Charge the refrigerant system following the automatic refrigerant charging meter operating instructions.
4. If the refrigerant flow stops before the refrigerant charge is complete, start the engine, select A/C operation and allow the refrigerant charge to
complete.
