No, the coolant reservoir does not need to be full all the time. It should be filled to the 'full' or 'max' line indicated on the reservoir. Overfilling can cause overflow when the engine heats up. Conversely, a low level might indicate a leak or needed maintenance. Regularly checking the coolant level can help prevent overheating and engine damage. Ensure the engine is cool before opening the reservoir to avoid burns. Maintaining optimal levels ensures the cooling system operates efficiently.
