Is Coolant Used for AC in Car?

Your air conditioner uses a specific refrigerant (known as Freon) to cool your car’s interior. The process of flushing coolant does not assist your A/C to remain calm, or vice the reverse.

Does Using AC in a Car Use Coolant?

Your engine’s cooling system uses coolant, also referred to as antifreeze, to keep your vehicle cool, even on the most scorching days. An additional cooling unit installed inside your car is the air cooling system. It utilizes refrigerant (known as Freon) to ensure you and your family are comfy and cool.

The AC System and Coolant

Let’s turn our attention to the AC system inside your vehicle. The AC system functions independently of the cooling system and does not directly use the coolant. Instead, it depends on an additional refrigerant, usually an R-134a-like compound that cools the cabin’s air.

The refrigerant moves across the AC system, taking warmth from the atmosphere and cooling it down before being released back into the vehicle. It is a continuous cycle of condensation, compression expansion, evaporation, and condensation, creating the cooling effect you feel.

The Relationship Between AC and the Cooling System

Although the AC system doesn’t use the same coolant as an engine cooling system, they have some standard components like the condenser and fan. These components are responsible for dispersing the heat created through the AC system to ensure the best cooling performance.

In certain vehicles, there are cars where the AC system and the cooling system could have the same reservoir; however, the fluids inside each system are distinct. The coolant used in the engine’s cooling system and the refrigerant used in the AC system have different functions and shouldn’t be mixed.
