A car's auto radiator serves as the heat exchanger of the vehicle to cool down the engine as it reach its maximum operating temperature level. Continuous flow of heat into the engine can cause destruction. To prevent such event, the car is equipped with a cooling system to achieve balance in the temperature range of the engine. Mitsubishi has one of the most efficient auto radiators in the industry. Mitsubishi auto radiators are vital component of the cooling system to protect the engine from the negative effects of excess heat. Its main duty is to cool the hot coolant that flows from the engine. It is made up of two important components; the overflow tanks located on either the top or bottom core of the auto radiator and the core consists of several small flat tubes.

Older vehicles, specifically those models used for five years and up are exposed to greater possibility of cooling system defects. Vehicles that are constantly used for a longer period of time are constantly exposed to changes in environment that can negatively affect the car's cooling system. In cases of hot summers, insufficient amount of cool outside air can affect the systems' performance as time advances. Other chemicals like salt from roads and ocean air can damage the metals making up the auto radiator core. Poor cooling system performance and engine damage can be prevented by having constant check, repair and maintenance. All hoses and tubes connected with the system must be thoroughly checked. The system must be regularly drained, flushed and refilled to prevent rust and corrosion formation.

Flushing of the cooling system must be done once a year to attain its maximum life span. The first thing to do is to cool down the engine. If the auto radiator cap is too hot, it means that the engine is not cool enough to touch. Remove the coolant from the drain plug at the bottom of the auto radiator and replace it with water. Be sure to close it properly to prevent spilling and splattering. Turn the engine on including the heater control to open the heater control valve. Then add cooling system cleaner depending on the required amount of the container and left the engine idle for about 30 minutes. After which, stop the engine and cool it down for five minutes before draining the solution from the system. For a second time, fill the auto radiator with water and left the engine idle for another five minutes. Then, mount new coolant depending on the required type of the vehicle.
