How to Add Water to a Car Radiator?
2 Answers
The method for adding water to a car radiator is as follows: Turn the pressure cap counterclockwise to open it, fill the coolant up to the marked line, then tighten and fully seat the pressure cap. Below are some related details: 1. The function of a car radiator: It absorbs heat from the engine block to prevent the engine from overheating and causing malfunctions. 2. Precautions when using a car radiator: (1) Prevent the radiator from overheating. (2) Regularly replace the coolant. (3) When choosing radiator water or antifreeze, opt for high-quality diluted types. (4) Address radiator issues promptly to avoid causing other faults from continued use.
As a master mechanic with 20 years of experience, I must emphasize that adding water to the radiator is not something to be taken lightly. First, ensure the car is completely cooled down, as high-temperature steam can cause burns. Locate the radiator cap with the pressure indicator in the engine compartment (usually yellow-green), and slowly turn it counterclockwise using a thick cloth for protection. Then, find the translucent white plastic expansion tank nearby, ensuring the fluid level is between the MAX and MIN marks. Slowly pour in dedicated antifreeze using a funnel, stopping at the MAX line—never fill it to the point of overflowing. Remember to tighten the radiator cap securely, start the car, and wait until the water temperature normalizes and the fan begins to operate. At this point, check the fluid level again and top it up if necessary. Key reminder: Plain tap water can easily form scale and clog the pipes, damaging the engine in the long run.
