Where is the Car Radiator Cap Located?

The car's radiator is generally installed at the front of the vehicle. Below is an introduction to the function and structure of the car radiator: Radiator Function: When the engine's water temperature is high, the water pump circulates water repeatedly to lower the engine's temperature. (The radiator is composed of hollow copper tubes. High-temperature water enters the radiator, is cooled by air, and then circulates back to the engine cylinder walls) to protect the engine. Radiator Structure: The car radiator mainly consists of a radiator core, water pipes, cooling fins, an upper tank, and a lower tank. The upper tank is located on the radiator, connected to the lower tank via water pipes. Hot water flows from the upper tank to the lower tank, where it cools down. The cooling fins form air channels, and with the help of the fan's suction and the relative wind speed when the car is moving forward, a large amount of cold air passes through these channels, absorbing the heat from the cooling water in the pipes and dissipating it into the atmosphere.
Recently, my car's water temperature has been running high, so I specifically researched the location of the coolant reservoir. What we commonly refer to as the 'radiator cap' is actually the expansion tank of the cooling system, which is how most modern cars are designed these days. It's located in the engine bay, near the radiator, with a prominently colored cap (usually yellow or black) bearing warning symbols. The exact position varies by vehicle - my German car has it on the right side, while my friend's Japanese car has it on the left. You can spot it when you pop the hood - it's a translucent plastic tank where the coolant level should sit between MIN and MAX marks when the engine is cold. Important reminder: never open the cap when the engine is hot, as the high-pressure steam can be extremely dangerous. Also, always use the correct type of coolant - mixing different colors can damage the cooling system.
