AC Off Due to High Engine Temperature Chevy Cruze [Fixed]
Driving a Chevy Cruze is a pleasant experience until you start feeling the heat when the AC suddenly turns off due to high engine temperature. It can be frustrating and uncomfortable, especially on hot summer days. In this blog post, we’ll cover some troubleshooting tips to help you resolve this issue and get your AC working again. We’ll also provide some preventive measures to avoid it from happening in the future.
Causes of AC Off Due to High Engine Temperature
Several factors can cause your Chevy Cruze’s AC to turn off due to high engine temperature. It’s essential to know these causes to prevent this issue from happening again. Here are some common reasons:
Low Coolant Levels or a Coolant Leak
If the coolant level is low or there’s a coolant leak, the engine can overheat, causing the AC to shut off. The coolant is responsible for regulating the engine temperature, so any deficiencies in this system can cause overheating.
Malfunctioning Thermostat
The thermostat is a vital component of the cooling system that regulates the engine’s temperature. If it malfunctions, it can cause the engine to overheat and turn off the AC.
Faulty Cooling Fan or Fan Relay
The cooling fan is responsible for pulling air through the radiator to cool the engine. If it fails or its relay malfunctions, it can cause overheating and turn off the AC.
Clogged Radiator or Coolant Passages
A clogged radiator or coolant passages can reduce the coolant flow, causing the engine to overheat and shut down the AC.
Malfunctioning Water Pump
The water pump is responsible for circulating the coolant through the engine block and radiator. If it malfunctions, it can cause the coolant to stop flowing and lead to overheating.
Broken or Damaged Serpentine Belt
The serpentine belt is responsible for driving multiple engine components, including the water pump. If it breaks or gets damaged, it can cause the water pump to stop working, leading to overheating and AC shut down.
Troubleshooting Tips for AC Off Due to High Engine Temperature
Here are some tips to troubleshoot and resolve the AC off issue:
- Check the Coolant Level
The first thing you should check when the AC turns off due to high engine temperature is the coolant level. If it’s low, it can cause overheating and AC shut down. Check the coolant level and top it off if necessary. If you notice a coolant leak, take your car to a mechanic for repairs.
- Check the Thermostat
If the coolant level is okay, the next step is to check the thermostat. A malfunctioning thermostat can cause the engine to overheat, leading to AC shut down. Have a mechanic inspect and replace the thermostat if necessary.
- Inspect the Cooling Fan and Fan Relay
The cooling fan and its relay are crucial components in the cooling system. If they fail, the engine can overheat, leading to AC shut down. Have a mechanic inspect and replace the fan or fan relay if necessary.
- Check the Radiator and Coolant Passages
A clogged radiator or coolant passages can reduce coolant flow, causing overheating and AC shut down. Have a mechanic flush the radiator and coolant passages to remove any blockages.
- Inspect the Water Pump
The water pump is responsible for circulating the coolant through the engine block and radiator. If it malfunctions, the coolant can stop flowing, leading to overheating and AC shut down. Have a mechanic inspect and replace the water pump if necessary.
- Check the Serpentine Belt
The serpentine belt is responsible for driving multiple engine components, including the water pump.
