How often should the coolant in a Leiling be replaced?
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 you notice any suspended particles, sediment, or discoloration in the coolant, replace it immediately and flush the system. Coolant replacement procedure: Before fully replacing the coolant, conduct a thorough inspection to check for any leaks or cracks in the pipes, with particular attention to the five-way hose. The five-way hose, named for its five connection points, distributes coolant to various parts of the vehicle. If there's any coolant leakage in this area, replace the hose or reseal the connections as needed. Drain the old coolant and flush the channels with clean water. Add water to the coolant reservoir and continue filling until clean water flows continuously through the engine cooling system. Then, idle the engine for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink tint. Keep adding clean water until the outflow is clear. Remember to disconnect the heater hose and drain the heater core completely. 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. Top up the coolant to the "MAXT" mark on the reservoir.
