It’ll be wise to research a bit on the vacuum pump that’ll provide the best values, especially if you’re buying one. So depending on the type of vacuum pump used in evacuating the AC system, vacuuming times may take longer than what’s mentioned in this guide to achieve desired results (sometimes, even longer than an hour in high-humidity conditions).

Most vacuum pumps will only achieve 20-25″ Hg instead of the ideal full vacuum of 29.6″ Hg. If the readout stays as is, then you’re guaranteed a leak-free AC system. Tip: Leave the manifold gauges hooked up to the vehicle for at least 30 minutes to an hour after closing the pressure lines and vacuum pump. A readout below zero is better since it means that the system can hold a vacuum (proof there are no leaks in the AC system). Let the evacuation process run for about 30-45 minutes or until the manifold gauges read zero. This latter step should finish evacuating the car’s system. Once done, open the red vapor valve on the manifold gauges. Then, open the blue liquid valve on the manifold gauges to remove liquid from the AC system. Slowly start opening the blue-colored valve on the recovery tank and keep an eye out for leaks. Connect the Hoses to the Recovery UnitĬonnect the yellow manifold connector to the corresponding port on the AC recovery unit or machine that says “in.” Then, get another yellow connector and hook up one end to the recovery unit port that says “out,” with the other end connecting to the blue-colored valve of the recovery tank. Don’t worry about size compatibility, as the end fittings of these connectors differ from each other (not to mention that they’re color-coded). The low-pressure port is on the return line between the compressor (view on Amazon) and the evaporator/firewall.Ĭonnect the high-pressure side with the red manifold connector and the low-pressure side with the blue manifold connector.

The high-pressure port is between the condenser and the expansion valve/orifice tube. Take note of the high and low-pressure sides under the hood of your car as you do this. Ensure they are closed before connecting them to your vehicle. Otherwise, you may suck the oil from the vacuum pump into the recovery tank once the vacuum has been created. Make sure you do these first few steps in this exact order.

Empty the Recovery TankĬlose the recovery tank valve and the vacuum pump. Leave the vacuum pump on for approximately an hour to remove all air and moisture from the recovery tank. Then, turn on the vacuum pump while simultaneously opening the blue-colored valve. Make sure that your recovery tank valves are closed as you do this. AutoZone or other similar auto shops may offer rentals. Remove air and moisture from inside the recovery tank by attaching a vacuum pump to its blue-colored valve. Prepare the recovery tank by opening the valves and releasing the nitrogen in the tank.
