Where to Open the Radiator Cap of Senya R7?

[DeDaniel]

Senya R7's radiator cap is opened on the radiator in the engine compartment. There is a coolant reservoir in the engine compartment with a cap marked "Do not open when the engine is hot." Detailed introduction is as follows: 1. Add antifreeze to the reservoir: Modern cars generally do not require regular addition of cooling water. The radiator is filled with coolant instead of water, as long-term use of water can cause scale buildup, affecting engine cooling. Antifreeze is not added directly to the radiator but to the reservoir connected to it, maintaining the upper limit of the scale. 2. Maintain fluid level: The fluid level should be kept between min and max. If it falls below min, it needs to be topped up with the same brand and specification of coolant, or the entire coolant should be replaced. The engine coolant warning only activates when the level is critically low. It is recommended not to add water to avoid scale buildup.
