The cooling system works by constantly passing coolant through channels in the engine block. Coolant, driven by a water pump is pushed through the cylinder block. As the solution passes through these channels, it absorbs heat from the engine.
The cooling system functions.
- It removes excess heat from the engine.
- It maintains the engine operating temperature the most efficient operation.
- It brings the engine up to the right operating temperature as quickly as possible.
Available Cooling System Parts:
- Radiators: Are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating.
- The radiator fans: Pulls cooling air through the car’s radiator. Positioned between the radiator and engine, cooling fans are particularly helpful when the car is stationary or moving at speeds too slow to force air through the grille.
- Radiator Air conditioners: Is a radiator positioned between the car’s grille and the engine-cooling radiator in which the gaseous refrigerant sheds heat and returns to a liquid state. The liquid refrigerant flows to the evaporator inside the dashboard, where it cools the cabin.
- Radiator Water Bottles: Works as an overflow reservoir is attached to the top of the radiator as coolant warms and expands out. When cooled, the coolant will get sucked back into the radiator. The hot coolant then flows across many tubes in the radiator, exchanging heat with the surrounding air.
- Radiator Hoses: Is an essential part of your cooling system that manages the flow of coolant from your water pump to the heater. Your radiator hose is a rubber device that removes excess heat from the coolant before it goes back to your engine to repeat the cycle again.
- Water Pumps: is a simple centrifugal pump that is driven by a belt connected to the engine’s crankshaft. Its primary purpose is to continually circulate coolant from the radiator to the vehicle’s engine block to prevent overheating. Modern water pumps are much more robust, but there is still a chance it could fail after many years or miles.
- Fan Blades: One of the specially shaped rotating parts (blades) of a mechanical fan which move and distribute air.
- Fan Belts: Are flexible rubber belts connecting engine components. A fan belt connects the engine cooling fan to the alternator and crankshaft pulley. Belts are also used to power components such as the air conditioner compressor, the power steering pump and the water pump.
- Viscous Fan Clutches: Is a coupling device located between the water pump shaft and the radiator. Its task is to improve the efficiency of the vehicle cooling system while reducing the engine load and energy losses caused by the fan itself.
- Fan Shrouds and Motors: Passive air-flow improvement devices. They mount behind your radiator and around your fan blades. In this position, they channel air-flow directly over your radiator and improve cooling-rates in the process.
- Radiator/Expansion Tank Caps: The function of the radiator cap or the expansion tank cap is to regulate the internal pressure in the cooling circuit. The radiator cap is a special cap consisting of a 2-way valve and a pressure relief valve.
- Thermostats: A device to detect temperature changes for the purpose of maintaining the temperature of an enclosed area essentially constant.
- Thermostat Housing: Is responsible for regulating coolant intake inside the engine bay. Coolant is responsible for transferring the heat of the engine out to the radiator bay to be dispersed into the air.
- Hose Clamps: Is an accessory that attaches onto a hose fitting such as a nipple or barb. The intent of these devices is to help seal and stabilize any hose configuration. Ultimately, clamps help to stop moving fluid from escaping from around a configuration.
- Oil Coolers: A radiator like component specifically designed to keep your oil cool. It consists of tubes and fins that allow for good airflow to pass through. Usually, they are placed where they can receive maximum airflow such as in front of or behind the radiator or fans.
- Other Cooling Components: The major components of the cooling system are the water pump, freeze plugs, the thermostat, the radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.
