How often should the coolant be replaced in a Leiling?
1 Answers
The coolant in a Leiling should be replaced every two years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the coolant level regularly and top it up if it's insufficient. If suspended particles, sediment, or discoloration are observed in the coolant, replace it immediately and clean the system. Coolant replacement procedure: Before completely replacing the coolant, conduct a thorough inspection to check for leaks or cracks in all pipes, with special attention to the five-way hose. The five-way hose, named for its five connecting interfaces to different parts, distributes coolant to various sections of the car. If there are any signs of coolant leakage in this area, replace the hose or resecure the connections as needed. Drain the old coolant, then flush the fluid channels with clean water. Add water to the coolant reservoir and continue filling until clean water flows 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 out may have a faint pink tint. Keep adding clean water until the outflow is clear. Remember to disconnect the heater hose and drain the water from the heater core. About an hour after draining, add new coolant through the radiator hose to allow quick flow into the radiator. Then, fill the coolant reservoir with another container of coolant until it's nearly full. Run the engine for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Add more coolant until it reaches the "MAXT" mark on the reservoir.
