Every passenger vehicle produced today with an internal combustion machine in it has a cooling ideas for the machine itself. All tasteless four stroke engines are liquid cooled and the cooling ideas is made up of many separate components.
The most tasteless components in a cooling ideas are: water pump radiator, thermostat, heater matrix/heater core, cooling fans, Coolant temp sensors, radiator cap and overflow bottle.
Starting with the water pump, it does as its name implies, pumps the water (coolant) straight through the ideas to aid in cooling. It works by centrifugal force, drawing coolant in straight through the inlet side and expelling it straight through the outlet in order to circulate it throughout the system.
The radiator is the systems retention tank which is specially designed to have fluid pushed in the inlet side of it, then as the fluid pushes straight through the radiator it is forced along the vanes, which are exposed to cool air by the air that passes over the radiator when driving, this then cools the coolant as it enters the outlet side of the radiator to go back into the system.
The thermostat is settled in the machine block in the direct coolant flow; the thermostats job is to regulate the flow of coolant straight through the ideas based on the climatic characteristic of the coolant itself. When the coolant is cold, the thermostat stays complete so it limits the amount of flow allowing the machine to heat the coolant that is inside of it to the proper operating temperature. Once this climatic characteristic is reached the thermostat opens allowing cool fluid into the block to repeat the process again.
The heater matrix allows the interior passenger compartment to use heat from the machine to warm the cabin. Warm coolant flows straight through the matrix and a fan mounted on the backside of it pushes the heat into the cabin.
The cooling fans serve an important purpose. If you are in heavy traffic or standing idle, no air is going over the radiator fins to cool the coolant. The fans make this so it is not a problem; they are governed by the coolant climatic characteristic switch. The switch activates once the machine climatic characteristic hits a definite set value, then sends current to the fans in order to force air over the radiator fins eliminating the need for the vehicle to be exciting to cool itself.
Two parts are left to general cooling systems, the radiator cap and the overflow bottle. These work in conjunction to each other. The radiator cap is meant to hold in pressure to a set rating, normally between 10 and 16 lbp of pressure. Since pressurised fluid has a higher boiling point it allows the water/coolant aggregate to surpass the boiling point before beyond doubt boiling. If the pressure in the ideas exceeds the cap rating, the cap is designed so that the spring depresses allowing the coolant to be expelled from the ideas into the overflow tank. When the ideas is working properly the overflow tank is designed to be able to re draw the coolant back into the ideas once the vehicle cools down in order to keep the coolant level to the proper level.
