After long-term use of the engine water tank, scale, rust and impurities will accumulate inside, resulting in a decrease in heat dissipation efficiency and even engine overheating. The following are the problems that may arise if the water tank is not cleaned in time:
| question | Consequences |
|---|---|
| Limescale accumulation | Heat dissipation efficiency decreases and engine temperature increases |
| rust deposits | Blockage of pipes, resulting in poor coolant circulation |
| Impurity contamination | Accelerates water pump and thermostat wear |
2. Engine water tank cleaning steps
To clean the engine water tank, you need to follow the following steps to ensure safe and effective operation:
1.Preparation: Make sure the engine is cool and prepare cleaning agents, gloves, brushes and other tools.

3. Cleaning frequency and precautions
The frequency of cleaning the engine water tank depends on the vehicle usage environment and water quality. It is generally recommended to clean it every 2 years or 40,000 kilometers. The following are cleaning recommendations for different usage environments:
| Usage environment | Recommended cleaning frequency |
|---|---|
| city road | Every 2 years or 40,000 kilometers |
| dusty environment | Every 1.5 years or 30,000 kilometers |
| high temperature area | Every 1 year or 20,000 kilometers |
Things to note:
1. Be sure to use special water tank cleaning agents when cleaning to avoid using strong acids and alkalis to corrode the water tank.
2. Rinse thoroughly after cleaning to prevent cleaning agent residue from affecting the performance of the new coolant.
3. If the water tank is seriously blocked or corroded, it is recommended to replace it with a new one to avoid safety hazards.
4. Recommendations for popular water tank cleaning products
According to the search data of the entire network in the past 10 days, the following are the water tank cleaning products that car owners are paying more attention to:
| Product name | Features | price range |
|---|---|---|
