Your vehicle radiator can see temperatures up to 230 degrees F, that’s hot! Your cooling system reduces the heat around the engine by circulating coolant/antifreeze.
Cooling System components ‘The Rad’ - Radiator
A series of fins around the radiator allows coolant to dissipate heat as air passes over these fins. Radiator cores can become clogged and require flushing or replacing.
Transfers coolant from the Radiator to the Engine Block. Water hoses are designed for extreme heat and pressure and must be replaced as per your vehicle maintenance guide.
A radiator thermostat controls when coolant is sent to the engine for heat management during operation. Without a properly operating thermostat your engine will overheat potentially causing serious damage. Signs of trouble with the thermostat include very high or very low temperature readings. Remember to always allow your engine to cool down when checking the radiator for problems. The radiator cap should be cool to the touch before opening.
The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running.
The fluid leaving the pump flows first through the engine block and cylinder head, then into the radiator and finally back to the pump.
The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be drawn from the center continuously. The inlet to the pump is located near the center so that fluid returning from the radiator hits the pump vanes.
