Because "calcium carbonate/magnesium" is a large amount in raw waterThe substances contained will be precipitated in a high-temperature environment, that is to say, the use of raw water to clean up is "making scale", and this method should not be used again.

Manual cleaning method: The car water tank needs to be disassembled, and the scale needs to be removed with a manual hammer, scraper and shovel. The descaling efficiency is low, the labor intensity is high, it is not easy to clean, and it is easy to cause secondary damage to the water tank.

Step 1- Start First, make sure that the engine is cold. The high-temperature engine indicates that the water tank is filled with extremely high-pressure high-temperature coolant - and may be burned when the water tank lid is opened. Cold water will also damage the high-heat engine. Step 2 - Clean the water tank. Open and fix the hood firmly to avoid accidental slipping.
