Does your car overheat when the AC is on? Symptoms, Causes, and Solutions Guide
One of the most important features of your car during the summer is AC. It keeps you cool and comfortable when you are driving. But what happens when your AC starts to overheat? We will discuss the causes of this problem and how to fix it.
When your car’s AC is turned on, the compressor turns on and draws the refrigerant in. This liquid is then compressed and turned into a gas. The gas is then sent through a condenser, which cools it. The cooled gas is then sent into the evaporator, where it removes heat from the air inside your car.
If your car ac is not working then these 6 reasons can be hidden behind it
It’s no fun to be stuck without air conditioning on a hot summer day, especially in a hot car, where temperatures can quickly reach 150 degrees or more. But the A/C is more than just comfort; this is also a security issue. In fact, one of the most dangerous places for someone during a heat wave is inside their car without an AC because the temperature can rise to dangerous levels.
leaking refrigerant– A refrigerant leak can occur at any point in the air conditioning process, and therefore, it is sometimes difficult to pinpoint the exact location of the leak. The most common places where leaks are found are the A/C unit hose connections.
clogged condenser- If the condenser becomes dirty or worn out, there may be less heat transfer from the refrigerant to the surrounding environment. Dirty or clogged condensers are one of the most common service problems in the commercial refrigeration and summer air conditioning sectors today.
broken condenser- If nothing appears to be blocking the condenser, it is possible that it is completely broken. A broken condenser can be caused by road debris passing through your car’s grille, being punctured and damaged by parts, or equipment failure.
electrical issues– When the A/C unit has stopped working, it’s probably the hardest problem to diagnose. First, a visual inspection of all wiring should be done to see if any wires are broken or worn out.
faulty cooling fans: When the fans are not working properly, your condenser may not be getting proper cooling. Over time, this can cause your car to start emitting only hot air.
bad compressor– The compressor keeps your A/C running all the time. Without it, refrigerant cannot circulate through the system and you will never get cold air. The most common reason for a compressor to go bad is a long period of time without use.
Does your car overheat when the AC is on? – Symptoms
temperature gauge– Your car may be equipped with either a coolant temperature gauge or a warning temperature lamp. Monitor the former so that it doesn’t go beyond 110C. If so, then your car is overheating.
Car is feeling physically hot– If your car is hot, and you can smell burning rubber or plastic, it could mean that it has overheated. The smell could be a sign of melting plastic and gaskets.
Tick-tick sounds from engine compartment– If engine oil is used for longer than the recommended period, it will cease to be viscous. This would mean that it could no longer perform its function in the engine. The knots formed after such an event will lead to friction.
engine stall- This happens automatically in overheated cars as a precautionary measure – whether the AC is on or not. The car will start only when the temperature drops.
strange smell– Your car’s engine is primarily metal, but has additional rubber seals and plastic components. Therefore, an overheated engine usually has a strange, ‘hot’ smell.
Ways to keep your car in good condition with proper guidance of luxury care
check coolant level regularly
This is a useful habit to avoid in your car engine overheating. Checking the coolant level in the radiator will help you add fluid if needed.
Manage AC use to reduce engine pressure
Whenever you drive your car on long journeys, manage the use of air-conditioner (AC). Switch off the AC from time to time to avoid extra load on the engine. Continuously running AC increases the chances of engine overheating during long journeys.
keep an eye on the temperature indicator
When you are enjoying a long road trip, don’t forget to check engine health through temperature indicator. This may be a gauge or a light on your dashboard, depending on the car you drive.
replace old car battery
An older car battery has to work harder to deliver the required power. Weak batteries require frequent recharge to provide energy, which leads to excessive engine heating.
An overheated cabin can also affect engine efficiency as the AC inside the car exerts more pressure to cool the interior. Therefore, you should try to maintain the normal temperature of the car at all times. Below are some tips to help you avoid car heating.
Park your car in the shade
Use mobile phone carefully when you are driving
Use the car a/c smartly
Leave windows slightly open for natural ventilation
