How To Remove Air From Car Ac System Without Vacuum Pump

husein | April 5, 2023 | How | No Comments

When the air conditioning system of your car stops working, it can be a terrible experience, especially during hot summer days. One of the major reasons behind the failure of the AC system is the presence of air in the system. The air prevents the refrigerant from flowing properly, and it can cause damage to the compressor. However, most people believe that removing air from the AC system requires a vacuum pump. But, that’s not true. In this article, we will show you how to remove air from car AC system without vacuum pump.

What Do You Need?

Before we start, let’s take a look at the things you will need to remove air from the AC system.

A can of refrigerant
A pressure gauge
A thermometer
A pair of safety goggles
A pair of gloves
A screwdriver
A wrench

Step-by-Step Guide

Now that you have everything you need let’s get started. Follow the steps below to remove air from the car AC system.

Step 1: Prepare the Car

First, you need to prepare your car for the process. Switch on the engine and let it run for a few minutes. Turn on the AC to the highest setting and let it run for a few minutes. This will help to circulate the refrigerant in the system.

Step 2: Attach the Pressure Gauge

Attach the pressure gauge to the low-pressure port of the AC system. The low-pressure port is usually located on the larger AC line. Make sure that the gauge is securely attached to the port.

Step 3: Take the Reading

Take a reading of the pressure on the gauge. If the reading is below the recommended level, it means that there is air in the system.

Step 4: Attach the Refrigerant Can

Attach the refrigerant can to the charging port. The charging port is usually located near the low-pressure port. Make sure that the can is tightly attached to the port.

Step 5: Add Refrigerant

Add refrigerant to the system while monitoring the pressure gauge. Keep adding refrigerant until the pressure gauge reaches the recommended level.

Step 6: Check the Temperature

Check the temperature of the air blowing from the AC system. If the temperature is not cold enough, it means that there is still air in the system. Keep adding refrigerant until the air blowing from the AC system is cold.

Step 7: Remove the Refrigerant Can

Remove the refrigerant can from the charging port. Make sure that you do this carefully to prevent any refrigerant leaks.

Step 8: Check for Leaks

Check the system for any refrigerant leaks. If you find any leaks, fix them before you continue.

Step 9: Repeat the Process

Repeat the process until the air blowing from the AC system is cold enough and the pressure gauge reads the recommended level.

FAQs

Q: Can I remove air from the car AC system without a vacuum pump?

Yes, you can remove air from the car AC system without a vacuum pump by using a can of refrigerant and a pressure gauge.

Q: How do I know if there is air in my car AC system?

You can know if there is air in your car AC system if the pressure gauge reads below the recommended level and the air blowing from the AC system is not cold enough.

Q: How do I fix a refrigerant leak in my car AC system?

To fix a refrigerant leak in your car AC system, you need to find the source of the leak and fix it. You can use a refrigerant leak detector to find the source of the leak.

Conclusion

Removing air from the car AC system is not a difficult task, and you don’t need a vacuum pump to do it. By following the steps above, you can easily remove the air from your car AC system and enjoy the cold air blowing from your AC system. Remember to wear safety goggles and gloves when working with refrigerant, and always check for leaks before you continue.
