Question:<\/strong> I\u2019m a bit overdue on a coolant flush and I\u2019ve noticed that my AC isn\u2019t working as well as it used to. Does coolant affect air conditioning?<\/p>\n\n\n\n

Answer:<\/strong><\/p>\n\n\n\n

Yes\u2014air conditioning (AC) temperature, air flow and even humidity can be impacted if you have low coolant levels.<\/p>\n\n\n\n

Your car\u2019s air conditioning system uses refrigerant, while your car\u2019s engine uses a mixture of water and antifreeze called coolant to maintain a healthy temperature. But engine coolant is not just an integral part to your engine\u2019s performance, because it\u2019s also needed for your car\u2019s AC system to operate at peak performance.<\/p>\n\n\n\n

The main purpose of your car\u2019s AC system is to cool down the interior of the vehicle, making for a more comfortable ride. If its coolant level is low, your car will struggle to maintain optimal engine temperature\u2014and in turn, your AC system will not receive the cooling capacity that it needs to run smoothly. Energy and efficiency will go toward cooling your engine, leading to reduced effectiveness and a weekend airflow throughout the AC system.<\/p>\n\n\n\n

The AC system can also change the humidity levels in your vehicle. For example, your car\u2019s AC system is intertwined with your defrost system. When you turn your defrost on, the AC starts to blow warm air to dehumidify the window. If low coolant levels have the system not running at peak efficiency, then the defrost system will also struggle, leading to higher humidity levels in the car. That struggling AC system may also generally struggle to take any moisture out of the cabin when trying to run normally.<\/p>\n\n\n\n

While coolant levels can have an impact on the AC system, keep in mind that coolant is for the engine itself. If your AC is not running properly, it\u2019s most commonly an issue with the AC system itself. Leaks in the system or compressor issues are the most common culprits. However, it could also be a problem with the cooling fan, filter, or a simple case of the system just needing to be fully recharged. While you can recharge the system yourself with a little knowhow, it\u2019s best to seek out your local mechanic should you suspect an issue with your AC system is causing it to run improperly.<\/p>\n\n\n\n

How do I add the coolant to my engine?<\/h2>\n\n\n\n

If you find yourself low on coolant, you can easily top off the system yourself\u2014but how to do so can differ depending on your vehicle. You can usually add coolant one of two ways: via the reservoir or directly through the radiator.<\/p>\n\n\n\n

Adding coolant via the reservoir<\/h2>\n\n\n\n

Follow these steps:<\/p>\n\n\n\n

    \n
  • Make sure your car is off and has adequately cooled down.<\/li>\n\n\n\n
  • Locate the coolant reservoir, which is usually a clear, plastic tank near your radiator.<\/li>\n\n\n\n
  • Put on gloves and safety glasses before slowly removing the reservoir cap to release pressure.<\/li>\n\n\n\n
  • Prepare your coolant by making sure it\u2019s the right type and mixture for your vehicle, which you should be able to find in the manual.<\/li>\n\n\n\n
  • Fill the reservoir to the max fill line by using a funnel.<\/li>\n\n\n\n
  • Slowly replace the cap until it is tight and close the hood.<\/li>\n<\/ul>\n\n\n\n

    Adding coolant via the radiator<\/h2>\n\n\n\n

    Adding coolant via the radiator is very similar to the reservoir option. To do so, follow these steps:<\/p>\n\n\n\n

      \n
    • Make sure your car is off, and has been so for long enough to adequately cool down.<\/li>\n\n\n\n
    • Locate the radiator.<\/li>\n\n\n\n
    • Slowly remove its cap to release pressure.<\/li>\n\n\n\n
    • Prepare your coolant mixture, making sure it\u2019s the right type for your vehicle, and pour it into the radiator via a funnel until the coolant level is once again full.<\/li>\n\n\n\n
    • Slowly replace the cap until it is tight and close the hood.<\/li>\n<\/ul>\n\n\n\n

      Before filling up your coolant, it\u2019s important to check the owners manual to make sure your vehicle doesn\u2019t require any added or specific steps.<\/p>\n\n\n\n
