Are AC water suitable for car radiators?

Answering this query isn’t easy to answer. There are two types of AC water such as freon and coolant. Coolant, which is the most popular kind of air conditioner generally does not have issues when it comes to your radiator. Freon however, in contrast can be a little more difficult to deal with.

Additionally, air conditioners using freon are banned in the US from 1995. It doesn’t mean all air conditioners using freon have been removed from the market, however. They were just banned from new models that were introduced from 1995 onwards.

The third point is that even though have an older model of an AC that runs on freon, and leaks into your car, the risk is low due to the fact that there isn’t much freon is to be leaking.

Fourth, If you own an AC that has coolant, and it leaks out to the car, that could pose a risk to your radiator. The reason this could be more harmful than AC liquid from the Freon-based AC spilling out is because coolant has lower freezing points than freon. The primary issue with your radiator frozen and not functioning properly is that it won’t hinder the engine’s temperature from rising and causing the engine overheating and costly repairs.

What kind of water would be best for car radiators?

The most suitable water for car radiators can be distilled. Distilled water doesn’t contain any minerals that could block the system, causing harm to cooling systems.

What is the best type of water for mixing with antifreeze?

It is essential to have the proper mix of antifreeze and water. It is possible to mix any water so it has the same volume of antifreeze. The water that flows cold is the ideal one to mix with antifreeze because it contains a greater salt content and calcium.


Are AC water suitable for car radiators? It is true that air cooling systems are a crucial and normal feature of automobiles these days. The water they use to cool the air is crucial to the radiator in your car. It is important to note that AC water is not recommended to substitute for coolant if you own an older system that uses Freon since it could be leaking into the engine , causing damage.

If you’re using distillate drinking water, instead of tap water or well-water then this shouldn’t occur in any way. You’ll have to top off your tank if it is too low, so keep the tank in check!
