AC Off Due to High Engine Temp – Preventing Overheating!

The degree of sadness in the summertime will be hyped up with the AC off due to the high temperature. Thus, the nightmare of melting into your vehicle’s seats as dingy odors with the turned-off AC under extreme warmth will make the knees shiver with fear and disgust. Hence, it is crucial to understand and address the issues that the turned-off AC due to high engine temperature will cause soon. Therefore we are going to circle around this issue under the topics: “reasons why the AC turns off,” “the connection between engine temperature and the AC system,” etc.:

Why is My AC Turning Off When the Engine Temperature is High?

The causes of the ultimate termination of a functioning AC might come to life with the effects of many reasons.

However, the AC is off due to high engine temp when the notification of “AC due to high engine temp” appears on the dashboard depending on the information gathered by the PCM through its sensors about extreme warmth or the nonfunctional electrical cooling fan.

Thus the simplest answer to the query is that the AC turns off itself when you are in extreme warmth as a safety feature that is embedded in the vehicle in the manufacturing process. This being the initial reason why the AC turns off in the high-tempered engine, there are many other reasons why it could occur,

• If your cooler has low coolant levels.
• If you are carrying around a clogged radiator.
• Nonfunctional radiator fan.
• Demolished thermostat.
• Squandered off blown head gasket.

What is the Relationship between Engine Temperature and AC System?

The AC system and the engine temperature in your car are soul mates who will not function properly without the presence of each other. Thus, both these systems’ presence and functions directly affect the vehicle and its proper functioning.

Suppose your vehicle is extremely hot; it will not function properly, causing many damages and complications like overheating and stalling.

Sometime it would damage the engine as well. If this is under your experience, you might have noticed that your AC may have turned off in these situations.

This happens due to overheating, and the AC turns off as a prevention methodology for future complications. AC turns off to avoid the multiplication of overheating. This ultimately happens due to a faulty cooling system or a damaged engine.

If you notice power losses in your car, you are in danger. Thus AC directly affects the engine temperature.  

Can High Engine Temperature Damage the AC System?

As we mentioned earlier, your vehicle’s engine and AC are like soul mates. The cooling system’s proper function directly affects the engine’s proper function and vice versa; thus, if the engine is suffering from overheating and high temperature, it will directly and severely affect the AC system of your vehicle, resulting in it turning off completely.

This is designed to be carried out as a safety feature to stop the engine from getting more damaged due to overheating.

While the engine temperature directly affects the AC’s smooth function, the facts mentioned earlier can also affect the AC functions.

How does the Vehicle’s Cooling System Affect the AC Operation?

The bond between the vehicles’ cooling system and the AC operation is like the bond between an employer and an employee.

They are connected with an immense amount of responsibilities. Thus, the coolant of your engine is the main partner responsible for the proper regulation of air entering the air conditioner.

If your coolant is at fault for a small amount of coolant provided, the amount of hot air that enters the air conditioner will increase, resulting in an increment of warmth and humidity. The worst that could happen due to this procedure is the turning off of the AC.

What are the Common Causes of High Engine Temperature?

High engine temperature can occur for millions of reasons that will make your jaw drop down, filled with amusement. Thus it is vital to acknowledge the causes of high engine temperature, which will be presented to you through the following list,

• If there are leaks in the cooling system in your vehicle (in hoses, in the radiator, water siphon, etc.) These factors cause issues with the cooling system, affecting the temperature level.
• If you have a faulty water pump which will make your car lack sufficient pressure to distribute the coolant through the engine will cause high engine temperature.
• If your radiator airflow is blocked with the accumulation of dirt, debris, and dust
• If you have acquired a bad thermostat, radiator, and worn-out hoses.
• The presence of a bad radiator fan and loose and broken belts.
• If there is an ongoing oil leakage into the cooling system happening, it will cause high engine temperature.

Are there Any Warning Signs that Indicate the AC will Turn Off Due to Engine Temperature?

If you are experiencing an “engine hot, AC off” situation, the only warning sign that might reach is the “engine hot, AC off” notification light that suggests that the vehicle is overheating and, as a result, and as a temporary solution, the AC will turn off.

Thus the AC would be turned off as an alternative solution as the power on AC will cause more overheating. However, if the situation worsens, you will experience sudden power drops in your car.

These power drops can become where your car completely terminates from functioning. Thus, in such a situation, you must react cautiously and head over to a technician as soon as possible.

Hence the notification light, excessive hot air within the car, sudden power drops, and sudden termination of a functioning car can be cited as the warning signs of an AC turn-off due to high engine temperature.

What Actions Can I Take If my AC Shuts Off Due to High Engine Temperature?

Suppose you are driving the east coast jamming to your favorite hits with the final destination in your head full of joy until you feel a sudden loss of power. Oops!! The car stopped. You are sure this is due to a high engine temperature as you ignored the AC turn-off notification. You are on your own. What can you do now? Do not panic. We are here to help you.

1. Turn the heat up; this will sound so idiotic; however, to ease the engine pressure, this will help.
2. Now pull over your car while turning on the hazard lights to inform other drivers.
3. Turn off the engine officially
4. Do not open the engine hood for a minute.
5. Now check the engine coolant level.
6. With all this information gathered, call a professional for help and deliver the information you gathered to help him.
