What is the normal level for coolant?

Coolant should be filled to the middle position between the upper mark (MAX) and lower mark (MIN) on the reservoir. The method for replacing coolant is as follows: Before completely replacing the coolant, conduct a comprehensive inspection to check for any signs of leakage or cracks in the pipes, with special attention to the five-way water pipe. The coolant flows through the five-way pipe and is then distributed to different parts of the vehicle to function. If there is any leakage of coolant in this section, replace the water pipe or resecure the connection as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continue filling the reservoir with water to allow it to flow continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink color. Continue adding clean water until the drained water runs clear. Note: Remember to disconnect the heater hose and drain all water from the heater core. After draining for about an hour, add new coolant through the radiator hose. Then, add another container of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as air is expelled from the cooling system. Add more coolant until it reaches the highest mark "MAXT" on the reservoir.
Having driven for over a decade, I pay great attention to vehicle maintenance. The coolant should normally be filled between the MIN and MAX marks on the coolant reservoir—that transparent or semi-transparent plastic tank in the engine compartment. If the level is below MIN, the engine may overheat and burn out; if it exceeds MAX, the expanding fluid under high temperatures can overflow and damage components. I always check when the car has cooled down, adding slowly from a bottle until it just reaches the MAX line. This ensures the cooling system operates efficiently and prevents roadside breakdowns. Doing this regularly also extends engine life. I make it a habit to check during seasonal changes—overfilling or underfilling is counterproductive. Experience has taught me that neglecting small issues invites bigger troubles, so now I emphasize this detail during every service.
