When you are sitting in your car with the AC on, you suddenly notice that the interior of the car starts to feel warm. You ignore this initially, thinking things will start to get cooler, but the problem persists, and finally, you notice that the car is starting to overheat, but only when the AC is on. Sounds familiar?<\/p>\n\n\n\n

Cars can overheat when the AC is on because the serpentine belt that turns the AC compressor also connects to many other engine parts, including the power steering pump, water pump, crankshaft, radiator fan, and alternator. \u00a0<\/strong><\/p>\n\n\n\n

If the AC compressor is not working well, the engine must work harder, making it overheat.\u00a0Another reason for overheating is when the AC condenser is not working properly, or the water pump creates excess heat.\u00a0<\/strong><\/p>\n\n\n\n

If you have this problem, you are not alone. This problem is faced by many others who have gone through this same issue with their car. An overheating engine is an important issue to resolve the first time it happens, or expensive damage could occur, taking time and patience to fix.<\/p>\n\n\n\n

What are the Reasons for Overheating?<\/h2>\n\n\n

<\/p>\n\n\n\n

If overheating happens only when the AC is on, you’ll be fairly sure that you need to check the AC compressor, the condenser, and the water pump. A car’s engine can begin to heat up quickly because heat is created in different ways as soon as the AC is on.\u00a0<\/p>\n\n\n\n

The engine has<\/strong> to work harder to create higher temperatures (if the AC compressor is bad), and the AC system creates heat that the condenser or water pump can’t cool, also creating higher temperatures. <\/p>\n\n\n\n

Be sure to turn off the AC if you suspect a problem and try to get it fixed as soon as possible. Just carrying extra water to put in the radiator when the engine gets hot is going likely to lead to engine failure.<\/p>\n\n\n\n


\n\n\n\n

1. Bigger Load Problem<\/h3>\n\n\n\n

The main reason is most likely the AC compressor. When the AC is on, the compressor needs to work like an engine, moving its cylinders to compress the refrigerant. This created a load (pressure carried) on the engine.<\/p>\n\n\n\n

If the AC compressor doesn’t turn as well as it is used to, the load on the engine is too much, creating excess heat. The AC compressor might have added an extra rotational load to the engine, so the first thing to check is your engine overheats.<\/p>\n\n\n\n


\n\n\n\n

2. Inefficient Working of the Cooling System<\/h3>\n\n\n\n

As the AC system moves refrigerant to the condenser, the engine fan blows over the condenser fins to regulate temperature. If the fins are clogged, the condenser temperature will rise. If the condenser gets too hot, it can lead to the engine overheating. <\/p>\n\n\n\n

Another reason the engine can overheat is when the radiator and condenser<\/strong> tubes get clogged<\/strong> over time. Liquid passes through the tubes, and corrosion or particles can cause clogged areas. \u200b<\/p>\n\n\n\n

This clogging can cause the refrigerant and the coolant not to flow properly, causing parts to heat up and, eventually, engine overheating. Taking a look at the radiator and condenser may help you figure out why things aren’t\u00a0functioning\u00a0<\/a>improperly.<\/p>\n\n\n\n


\n\n\n\n

3. Faulty Fan<\/h3>\n\n\n\n

When the car gets overheated at slow speeds or a stop, the likely culprit is the engine fan. This problem is caused when there is a lack of airflow through the radiator and condenser. The fan could be broken, or there could be a blockage in the fins, radiator, and condenser. Also, check for a faulty fan switch.<\/p>\n\n\n\n

Consider getting a new fan, or you might want to check the fan assembly or the fan clutch.<\/p>\n\n\n\n


\n\n\n\n

4. Fault in the Temperature Sensor<\/h3>\n\n\n\n

This possibility is unlikely but happens in some cases. The coolant temperature can be measured and compared to the temperature indicator on the dashboard. Sometimes due to the fault in the temperature sensor, this reading is false, which causes inaccurate dashboard indicator readings.<\/p>\n\n\n\n

If it reads normal and the engine temperature is rising, your engine could overheat. You should check the functioning of the thermostat if you suspect this might be the reason your car is having temperature readings issues. <\/p>\n\n\n\n
