How often should the coolant be replaced in a Lavida?
2 Answers
The coolant in a Lavida should be replaced every two years. This is just a reference interval. For commercial vehicles with higher mileage, the replacement interval should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Regularly check the coolant level and top it up promptly if it is insufficient. If suspended particles, sediment, or signs of deterioration 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 any leaks or cracks in the pipes, with particular attention to the five-way hose. The five-way hose, named for its five connecting interfaces to various parts, distributes the coolant to different 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 and flush the channels with clean water. Add clean water to the coolant reservoir and continue filling until water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may appear slightly pink. Continue flushing with clean water until the water runs clear. Remember to remove the heater hose and drain all water from the heater core. Approximately one hour after draining, add new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, fill the coolant reservoir with another bottle of coolant until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Top up the coolant to the maximum mark "MAXT" on the reservoir.
I've been driving a Lavida for several years and have plenty of experience with coolant. Generally, it's recommended to change it every two years. But it really depends on how you use your car. For example, if you often drive in the freezing north, you might need to change it every year and a half. I drive frequently, so I check it every 20,000 kilometers. Remember to pop the hood and check the coolant level and color. If it turns yellow or has debris, you need to act fast. Coolant isn't just for preventing freezing and boiling; it also prevents corrosion and engine rust. Delaying can cause big problems. Last year, I tried to save money by not changing it, and my engine overheated, triggering an alarm. The repair cost was ridiculously high. Following the maintenance manual is the way to go—don’t be lazy like I was. Set a reminder on your phone so you don’t forget.
