* Severe overheating leading to damage: If the engine overheats severely enough to cause significant damage, it's possible that related components could be damaged, indirectly impacting the AC system. This is unlikely unless the overheating is extreme and prolonged.
* Reduced power from the engine: An overheating engine might struggle to generate enough power to run the AC compressor effectively. This would result in reduced cooling performance or the AC cycling on and off more frequently, rather than a loss of refrigerant.
* Stress on other systems: Extreme overheating could put stress on the entire vehicle, possibly leading to failure of unrelated components like the AC compressor or its related components (though again, this is not a direct effect of the overheating).
In short, the coolant system and the AC system are independent. Overheating indicates a problem with the cooling system, not the air conditioning system itself.
