Do cars need to add water? Where is the water tank located?

Cars do need to add water, which generally refers to the engine coolant. The water filler port of the car's radiator is usually located on the right side of the engine compartment, often next to the windshield washer fluid filler port. Method for adding antifreeze: Unscrew the radiator cap, open the radiator drain valve to release the antifreeze. Insert a rubber hose connected to a tap water pipe into the radiator filler port, turn on the tap to allow tap water to continuously flow through the engine cooling system. During this flushing operation, keep the engine idling. Continue this process until clean water flows out from the radiator. Turn off the tap, wait until all water in the cooling system is drained, then close the radiator drain valve. Add antifreeze from the radiator filler port until the radiator is full. Unscrew the reservoir cap, add antifreeze up to the "Max" mark, being careful not to exceed it. Main functions of the radiator: When the engine's water temperature is high, the water pump circulates the water repeatedly to lower the engine's temperature, thereby protecting the engine. In winter, if the water temperature is too low, the water circulation stops to prevent the engine from getting too cold.
I've been driving for many years, and sedans don't need water. Adding water can only damage the cooling system and easily cause metal parts to rust and corrode. The water tank is usually called an expansion tank, located in the engine compartment. You can see it as soon as you open the hood—it's a translucent plastic container with min and max markings to indicate the fluid level. The position varies by car model but is generally near the radiator fan or in a corner at the front of the car. When I was young and didn't know better, I once added tap water, which caused the engine to overheat and smoke, nearly leaving me stranded on the road. I recommend checking the coolant level regularly. If it's too low, add some dedicated coolant or distilled water, but avoid tap water. Coolant comes in red or green colors—just choose the right one. Make it a habit to check monthly to avoid trouble and protect your car's lifespan.
Cars don't need water, they require coolant instead. The reason is that adding water can cause internal rusting or overheating due to water's low boiling point. The coolant reservoir is located in the engine bay, with its exact position depending on your car model - usually it's that small marked container near the radiator end. My old car had the radiator positioned at the front left corner, clearly visible when opening the hood. Incorrectly adding water may clog pipes or corrode components, and frozen water in winter makes things worse. I recommend checking the fluid level quarterly - when low, just top it up with coolant from the bottle, super easy. Never use tap water as it contains impurities that can cause damage. Remember to ensure the engine is cool before operation, and don't randomly unscrew the cap to avoid burns.
