Where is the water drain valve of the Yuexiang radiator?

The water drain valve of the Yuexiang radiator is located at the lower left corner of the radiator, where there is a plastic screw, which serves as the drain outlet. Water filler port: The water filler port of the car radiator is generally located on the right side of the engine compartment, usually next to the windshield washer fluid filler port. Radiator: The radiator is a crucial component of a water-cooled engine, serving as an important part of the engine's cooling circuit. It absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, the temperature rise after absorbing the engine block's heat is not significant. Therefore, the engine's heat is dissipated through the liquid cooling circuit, using water as the heat transfer medium. The heat is then dissipated through large-area cooling fins via convection to maintain the engine's optimal operating temperature.
I remember last time helping my friend with his Changan Alsvin, the radiator drain valve is usually located at the bottom corner of the radiator, which could be a plastic knob or a metal drain plug. To find it, it's best to let the car cool down for at least two hours to avoid burns, then crouch down and look behind the front grille—you'll spot the small valve at the lower end of the radiator. A simple wrench should do the trick to loosen it, but be gentle to avoid breaking it. Prepare a pan to catch the old coolant, as it's toxic—don’t let it splash on you or dispose of it improperly to avoid environmental harm. Replacing coolant is crucial; I recommend doing it every two years to protect the engine from overheating and extend the vehicle's lifespan. If you can’t locate it or are unsure about the model, check the owner’s manual—it has a detailed diagram of the exact position. Don’t attempt it blindly.
I often maintain my car myself. The drain valve of the Changan Alsvin's radiator is located at the very bottom of the radiator, with a very intuitive design. Once when I was changing the coolant myself, I could easily spot it by simply squatting at the front of the car. The whole operation took only 10 minutes: first, let the engine cool down, put on gloves to prevent splashing, unscrew the valve, and the fluid will flow out naturally. After draining, just replace it with new coolant and you're done. Importantly, don't neglect the cooling system. Timely draining prevents rust and blockages, saves some fuel costs, reduces engine failures, and ensures safer driving. Remember not to operate when the engine is hot—even beginners can handle it.
