We often get lots of questions about car cooling system – the system that cools car engine and keeps it at a proper operating temperature. To answer this question better, we shall look at the coolant itself and second, the parts that make up the cooling systems.
The engine coolant consists of a mixture of water and anti-freezing elements that circulate through the engine to draw off heat. If the engine doesn’t have enough coolant, it won’t be cool. You also need to use the right kind of coolant. Different vehicle types require different coolant formulations to protect it against corrosion.
The coolant also needs to be fresh. Over time and as your vehicle gains more miles, the anti-corrosion additives in the coolant are depleted and this may make the coolant to start eating away the cooling parts.
The cooling system components
The cooling system components will all wear out and would need to be replaced. Starting with the radiator, it shall need to be replaced at some point, due to leakage or clogging. Depending on the damage, the radiator is cleaned, repaired or replaced. Also, the radiator pressure caps can be replaced, in the event, these caps can no longer hold the proper pressure.
The coolant needs a proper mix and balance of water and antifreeze agents that circulate through the engine to draw off heat.
The main component of your car’s engine cooling system is the radiator. Its purpose is to help prevent heat from the engine. The radiator relies on the water pump to help in circulating the engine coolant through its core so that it can release excess heat that has been absorbed by the engine coolant in the engine block.
The thermostat can be found between the engine and the radiator. It opens and closes with it’s primary function being to block the flow of the coolant into the engine until the car engine has warmed up, to the required operating temperature.
The water pump makes the heart of the cooling system. It circulates the engine coolant through the entire cooling system.
Last is the fan. Fan works with the engine computer or thermostatic switch to turn on when the temperature of the coolant goes above the set point to help in cooling down the radiator and thus prevent overheating.
Engine damage resulting from overheating can be very expensive to fix and so it is important to maintain your vehicle’s cooling system properly with scheduled coolant replacement and frequent inspections of the cooling system.
