As is well known, one of the most common causes of car damage comes from the car radiator. Even though it is very easy to maintain, it turns out to be easily damaged too, you know. When the machine is turned on and running, The piston moves up and down between 1500rpm at idle to 8000rpm when flat-out, creating friction and heat. Ways to keep it cool, namely by channeling water through channels in the engine block to the radiator.
It is very important to take care of it so that your car's engine radiator stays cool. Signs that something is wrong under the hood will start with the water temperature gauge, which it should run no later than 90 degrees Celsius. If the temperature starts to rise then you should stop your journey. Other signs include a burning smell and steam coming out from under the hood.
Quoted by Otodiva.com from Gulf News, The following are things that can cause the radiator to overheat, among them namely:
1. Low coolant level in the radiator
Coolant or cooler is an antifreeze mixture (Ethylene Glycol) and water is a liquid that is pumped around the engine and kept cool with the help of the radiator. The purpose of antifreeze is to keep the water in the radiator from freezing in cold temperatures and boiling in warmer climates.
Low coolant levels in the radiator are one of the main causes of vehicle overheating. The drop in level can be caused by various reasons such as a leak in your head gasket which is a serious problem or the heater core.
It is recommended to replace the coolant every time the radiator is serviced. Ideally this should be done every year. You should check your coolant level at least once a month.
2.Clogged radiator
A common cause of blockages in radiators is dirt, dead insects, or loose debris such as stones. This will block air flow through the radiator, resulting in overheating. Open the hood and you can usually see this clearly.
If there is no obvious object clogging your radiator, it could be an internal blockage. Scan the surface of the radiator for cold spots using an infrared thermostat if you have one. If you don't have it, You can open the radiator cap when the car is cold, then check the radiator fluid for any brown discoloration or contamination in the coolant such as floating dirt. If there is, it means your radiator has an internal blockage.
3. Heat exchanger machine
Traditionally radiators are made using copper and brass cores. But the cost-effective and weight-saving aluminum cores are slowly being replaced using plastic tanks. The reason for this change is because aluminum radiators are cooler than copper brass radiators. The heat transfer rate in aluminum is impressive among common metals.
If you have an older car with copper and brass pipes, then the age of the car could be the source of the problem because a new car will not be affected by this with an all-new engine from the factory.
4. Close the radiator
A malfunctioning radiator cap is causing the radiator to overheat, a very common and overlooked cause. If the radiator cap is not installed properly, this could result in coolant leaking.
The radiator cap also helps maintain proper water pressure, If it is not installed correctly it will cause the pressure to be disrupted.
5. Thermostat
The thermostat is a valve which is a key component of the radiator. If the thermostat is stuck closed then the hot water in the system cannot flow back to the radiator to be cooled. This results in overheating Thermostats are relatively easy to replace and are the most common cause of overheating.
