Does an Engine Need to be Running When Adding Coolant?
In general, it is recommended to turn off the engine before adding coolant. The main reason for this is safety. When the engine is running, the coolant is circulating through the system and is under high pressure. Opening the coolant reservoir cap while the engine is running can cause the hot coolant to spray out, potentially causing burns or other injuries. Additionally, running the engine with a low coolant level can cause damage to the engine and its components. Therefore, it is always best to turn off the engine and allow it to cool down before adding coolant.
