In this guide, you will find instructions on how to charge the Mazda air conditioner system with refrigerant. If your Mazda is blowing hot air, it may be due to a small leak in the A/C system.
This procedure can restore your A/C operation if a small refrigerant leak is present. If a large A/C leak is present, the system must be repaired by a certified mechanic.
What you will need
Here is what you will need to charge the A/C system on your Mazda.
- Air Conditioner Recharge Kit - Recommended refrigerant type can be found on a sticker under the hood or owner's manual.
- Gloves
- Safety Glasses
Procedure
- Park your Mazda in a safe area. Engage the parking brakes and ensure the vehicle is in Park.
- Pull the hood release under the dashboard on the driver's side. Prop open the hood.
- Locate the low-pressure port. This is where you add A/C refrigerant on a Mazda 5. There is a low-pressure port and high-pressure port. The connectors that come with the AC recharge kits will only fit on the low-pressure port.
- Remove the cap and connect your A/C hose to the charging port.
- Turn on the engine and allow it to idle. The transmission should be in Park.
- Turn on the A/C and set the blower fan to max.
- Start adding refrigerant to your Mazda air conditioner system with the engine running at idle.
- Press the trigger on the A/C recharge kit to charge your Mazda A/C. The engine should be running when you charge your Mazda A/C. Follow the instructions as directed on your A/C recharge kit.
That's it!
Be careful not to overcharge the A/C system. Overcharging a Mazda air conditioner with freon can cause damage to the A/C system. It will not make the A/C colder.
