1. Park the Montero in a shady area and turn off the engine.
2. Put on your safety goggles and work gloves.
3. Locate the low-pressure service port on the air conditioning system. It is usually located on the side of the compressor or on the receiver drier.
4. Connect the low-pressure hose from the manifold gauge set to the service port.
5. Connect the vacuum pump to the high-pressure service port.
6. Turn on the vacuum pump and evacuate the air conditioning system for at least 15 minutes.
7. Turn off the vacuum pump and close the valves on the manifold gauge set.
8. Connect the refrigerant can to the low-pressure hose on the manifold gauge set.
9. Open the valve on the refrigerant can and slowly start to add refrigerant to the system.
10. Watch the gauges on the manifold gauge set and add refrigerant until the pressure reaches the specified level for your vehicle.
11. Once the system is fully charged, close the valve on the refrigerant can and disconnect the hoses from the manifold gauge set.
12. Turn on the engine and let it run for a few minutes to circulate the refrigerant.
13. Check the air conditioning system to make sure it is working properly.
Note: If you are not comfortable recharging the air conditioning system yourself, you can take your vehicle to a qualified mechanic to have it done.
