Are you experiencing overheating issues when your car’s AC is running?

Don’t sweat it; we’ve got you covered. Our comprehensive troubleshooting guide will help you keep your cool on the road.

But first, let’s understand the relationship between the AC system and the engine.

Impact of the AC System on Engine Temperature

Understanding the Relationship:

Our car’s engine generates a lot of heat when it runs. To keep it from getting too hot and causing damage, your car has a cooling system. This system includes a radiator, a water pump, and a fan.

When the AC is activated, it places an additional load on the engine. The AC compressor, which circulates the refrigerant to cool the cabin air, is driven by the engine.

This extra load can strain the engine, leading to increased heat generation.

Causes of Overheating When the AC is On

1. Low Coolant Level

Your engine relies on a steady supply of coolant to maintain a stable temperature. Low coolant levels can occur due to leaks or negligence. When the AC is running, it can exacerbate the situation, as there’s less coolant available to dissipate the excess heat generated.

2. Radiator Woes

The radiator is like the engine’s cooling partner, transferring excess heat away from the engine. A damaged or clogged radiator won’t efficiently perform this crucial function, especially when the AC is on, causing the engine to overheat.

3. Water Pump Troubles

The water pump is responsible for circulating coolant through the engine and radiator. When it fails to function correctly, it hampers the cooling process, leading to overheating. This problem becomes more pronounced when the AC is in use.

4. Faulty Radiator Fan

The radiator fan assists in dissipating heat from the radiator. When it’s not working as it should, the radiator won’t be able to cool down efficiently, causing the engine to heat up. This can be more noticeable when the AC is on due to the additional heat generated by the AC system.

5. AC Compressor Issues

Problems with the AC compressor or the AC system can lead to additional heat generation. If the compressor is overworking due to a malfunction, it can strain the engine and lead to overheating, especially when the AC is in use.

6. Clogged Radiator

A radiator covered in debris or clogged with dirt and bugs can’t effectively cool the engine. Regular cleaning and maintenance are essential to prevent these issues from arising.

7. Broken Serpentine Belt

The serpentine belt drives many components, including the AC compressor. If it’s worn or broken, it can cause problems in the AC system and affect engine cooling, particularly when the AC is running.

8. Insufficient Engine Oil

Low engine oil can lead to increased friction and heat in the engine, making it more prone to overheating.

9. Cooling System Culprits

Issues with components like the thermostat, hoses, or other parts of the cooling system can disrupt the temperature regulation of your engine, which becomes more apparent when the AC is operational.

Preventing Overheating Tips

1. The Importance of Regular Maintenance: Regular maintenance checks, including inspecting the coolant level, radiator condition, and the overall health of your cooling system, can help prevent many of the issues mentioned earlier. By addressing these issues proactively, you can ensure your car runs smoothly even with the AC on.

2. Summer Survival Tips: During hot summer days, consider reducing the strain on your engine by using some simple strategies. Park in the shade, and consider starting your car without the AC for a few minutes to allow the engine to cool down before turning it on.

Don’t Sweat It!

Don’t let an overheating engine spoil your road trips.

By understanding the relationship between your car’s AC system and engine temperature, identifying common causes of overheating, and embracing preventative maintenance, you can stay cool and worry-free while cruising down the highway.
