AC Off Due to High Engine Temperature

If your AC keeps shutting off, it’s probably due to an overheating problem. The problem could be caused by a number of factors. These include the airflow through the condenser, the radiator, and the cooling fans. To resolve this problem, you’ll need to have your engine inspected by a certified mechanic.

Airflow through the condenser

If you notice that airflow through the condenser is reduced when your AC is off, your engine temperature is probably high. This can be caused by a number of things, including a malfunctioning fan motor or a buildup of debris near the condenser. If you’re not sure if this is the problem, you can test the airflow through the condenser yourself with some easy-to-use equipment.

One of the most common reasons for airflow through the condenser to be low is because the car’s cooling system is not working properly. A leaky cooling system could cause an engine component to fail, and it can lead to serious wear and tear on your car. Therefore, it’s imperative to take your car to a mechanic for an inspection.


If you are experiencing engine overheating, you should check the coolant temperature sensor. This sensor measures the temperature of the coolant mixture in the engine and sends a signal to the ECU to adjust the fuel injection time and radiator fan accordingly. If you notice that the temperature is out of range, then the sensor has likely failed. This can result in the cooling fan not working or the engine overheating.

A malfunctioning cooling fan, radiator, or hoses can also cause the engine to overheat. It is difficult to identify these problems if you are not a mechanic. If you suspect that the problem is with the cooling system, you should take your car to a mechanic immediately.

Cooling fans

If your car’s A/C is off due to high engine temperature, the problem is most likely the electric cooling fan. Overheating the engine can cause warped cylinder heads, decreased power, irregular firing, and even excessive oil burn. Additionally, it can damage other engine components.  Fortunately,  there  are  some  simple  steps  you can take to solve this problem.

First, check your car’s cooling fans and radiator. Check if they’re clogged or leaking coolant. If you’re unable to find a leak, you should consult with a mechanic. If you’re a novice, it’s best to have a professional inspect the cooling system and replace any damaged parts.

Serpentine belt

If your car has the “Serpentine belt and ac off due high engine temp” symptom, it’s time to bring it in for a check-up. The serpentine belt is the main power supply to the water pump in your car. If the belt is worn out or damaged, it can cause your engine to overheat. Fortunately, you can take your vehicle to a local Jiffy Lube to have the belt replaced.

When the power control module detects that your car’s engine has reached an unsafe temperature, it will shut off the air conditioning. Keeping the engine at a safe temperature is crucial to prevent damage to other parts. High engine temperatures can cause warped cylinder heads, excess oil burning, and other problems.

Damage to the engine

High engine temperatures can damage the components of your car. Although most cars have durable parts, prolonged exposure to high temperatures can lead to damage. A cooling system helps regulate engine temperature by sending coolant through the engine. The flow of this coolant is controlled by a thermostat. As the engine temperature rises, the thermostat will open and close depending on the engine’s needs. Excessive heat can deform and damage engine parts, especially the rotating parts.

Overheating can also cause the pistons of the engine to expand. When this happens, they can scrape against the cylinder walls. Piston damage can lead to serious problems with the engine and is costly to repair. Overheating also damages the engine block, causing cracks and leaks. If these damages go unrepaired, the engine may not run properly, which may lead to other problems.
