Why Does My Chevy Impala Say ‘Engine Hot A/C Off’? Here’s What You Need to Know!

The Chevy Impala has a built-in computer system with sensors that monitor the engine temperature. If the engine gets too hot, the computer will activate an alert, which tells the driver that the engine is hot and to turn off the air conditioning. This is done as a safety precaution to prevent further damage to the engine due to overheating. The AC must be turned off in order for the engine to cool down and return to its normal operating temperature. If this alert is ignored and the AC remains on, it can cause serious damage to the engine and other components of the car.
