The summer heat has arrived and, as temperatures begin to rise, many of us are starting to crank up the air conditioning in our cars. But before you do, you may want to consider if your car’s coolant is up to the task.

Expert insights about Coolant and Air Conditioning

Recent data from the automotive industry has revealed some interesting trends when it comes to air conditioning and coolant. Studies suggest that the type of coolant used to cool the engine can have a significant impact on the performance of the air conditioning system.

How does your car air conditioner work?

To understand why this is the case, it’s important to have a basic understanding of how your car’s air conditioning system works. Air conditioning systems work by transferring heat from the car’s cabin to the outside air. To do this, the air conditioning system needs to rely on the coolant from the car’s engine to transfer the heat away from the cabin.

Is the type of coolant important?

The type of coolant used in the car’s engine is important, because different types of coolant have different capabilities in terms of heat transfer. When the coolant is not up to the task, it can reduce the performance of the air conditioning system and cause it to become less effective.

Most modern cars use a standard coolant known as R134a, which is designed to be effective in temperatures as low as -40°F. However, some older cars may use a different type of coolant, such as R12, which is not as effective in cooler temperatures and can lead to a decrease in air conditioning performance.

Make sure your air conditioner is working efficiently

To ensure that your air conditioning system is working as efficiently as possible, it is important to check the type of coolant used in your car and make sure that it is up-to-date. If your car is using an older type of coolant, you should consider having it replaced with a modern one. This will help ensure that your air conditioning system is operating at its peak performance and can help you stay cool in the summer heat.
