Why Is the Car Always Losing Coolant?
1 Answers
The primary reason for the reduction is natural evaporation, with normal consumption being about half a liter per year. Rapid consumption may be caused by leaks or poor circulation, with leaks accounting for about 80% of cases. Coolant Replacement Method: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leaks or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connecting interfaces to different parts. The coolant flows through the five-way hose and is then distributed to various parts of the car to function. If there are signs of coolant leakage in this section, replace the hose or reseal the interface as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir and continue filling it until water flows continuously through the engine cooling system. Then, let the engine idle for 3 to 5 minutes to circulate the water. The water initially flowing out of the reservoir may have a faint pink tint. Continue adding clean water until the outflow is clear. Note: Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose—this allows the coolant to flow quickly into the radiator. Then, add another bottle of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As the cooling system expels some air, the fluid level will drop slightly. Top up the coolant to the "MAXT" mark on the reservoir.
