Question: Does engine coolant have anything to do with AC?

Freon, or coolant, is the chemical in the air conditioning system that cools the air. If the system is leaking, then this chemical will eventually run out. Today’s A/C systems are more sensitive than the older ones. The air conditioner will not work properly if there is not enough of this chemical.

Can low coolant affect air conditioning?

In a properly operation system the engine coolant temperature should not affect the cooling of the air conditioner. But technically it is not the high coolant temperature causing the A/C problem. It is the lack of airflow across the condenser and radiator causing one problem in two systems.

Does engine coolant affect ac performance?
