As the AC system moves refrigerant to the condenser, the engine fan blows over the condenser fins to regulate temperature. … This clogging can cause both the refrigerant and the coolant not to flow properly, causing parts to heat up and eventual engine overheating.

Can overheating cause AC to stop working?

Leaking refrigerant Luckily, a drop in refrigerant charge usually sends off warning signs before compressor failure, and overheating is one of them. The lower amount of refrigerant pushes the AC to run longer, and this can trigger a tripped circuit breaker.

What gets damaged when engine overheats?

If something limits or interrupts that process, engine overheating is likely — and extensive damage to engine parts like gaskets, bearings, pistons and cylinder heads may be moments away. Engine coolant is typically green or red in color.
