How An Engine Cooling System Works How A Car Works In order for the system to work, the coolant needs to move throughout the system. the water pump uses power from the crankshaft and serpentine belt to force coolant into the engine and through the rest of the cooling system. allow your engine to run for a few minutes before inspecting your water pump. visually check for leaks around the unit. The primary job of the cooling system is to keep the engine from overheating by transferring this heat to the air, but the cooling system also has several other important jobs. the engine in your car runs best at a fairly high temperature. when the engine is cold, components wear out faster, and the engine is less efficient and emits more.
How Car Cooling System Works Youtube Pressurizing the system simply raises the boiling point of the coolant and that’s controlled by the radiator cap (or expansion tank cap on modern machinery). the caps are pressure rated depending on the car, so it’s important to fit the right cap. pressures are relatively modest, typically 15 to 18 psi, but to achieve that range the rubber. The basics remain the same. the cooling system is filled with a 50 50 mixture of ethylene glycol and water. this fluid is referred to as antifreeze or coolant. it is the media used by the cooling system to remove engine heat and disperse it. antifreeze is kept under pressure in the cooling system as the heat expands the fluid, up to 15 psi. Below we explain what a car cooling system is, what it does and how to maintain it. air cooled vs liquid cooled. air cooled engines are yesterday's news, harking back to models such as the original vw beetle and porsche 911. nowadays, all new mass produced car engines use a liquid cooling system, and that's what we're focusing on here. Steps. 1. consult your vehicle specific owner's manual regarding the proper ratio of coolant to water. an improper balance of coolant can cause damage to the water pump. 2. wait until the engine is completely cool before proceeding. 3. twist off the radiator cap by turning it counterclockwise. 4.
