How to Replace the Coolant in a Haima Automobile?

The method for replacing the coolant in a Haima Automobile is as follows: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. The five-way hose gets its name from having five connections that link various parts. The coolant is distributed to different sections of the car through this hose after passing through it. If there are signs of coolant leakage in this section, replace the hose or re-secure the connections as necessary. Drain the old coolant and then flush the liquid channels with clean water. Add clean water to the coolant reservoir, ensuring it continuously flows 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 appear slightly pinkish. Continue adding clean water until the water runs clear. Remember to disconnect the heater hose to drain the water from the heater core. Approximately one hour after draining, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. 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. 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.
Last time I changed the coolant for my Haima car by myself, and it was quite easy. I first prepared the tools: new coolant (I bought the ethylene glycol-based type with a 50% concentration as per the manual), a funnel, an empty bucket, and gloves. After parking the car and letting it cool down, I located the radiator drain plug under the hood (usually at the bottom), unscrewed it to let the old fluid drain out, and used the bucket to catch it to avoid contamination. Once the old fluid was completely drained, I rinsed the radiator briefly with clean water to remove any residue, waited for the water to drain, and then poured the new coolant into the reservoir up to the marked line. After finishing, I started the car to check that the water temperature was normal and then inspected for leaks. The whole process took about half an hour, saving money and giving me peace of mind. Generally, changing the coolant every 2 years helps prevent engine corrosion.
When changing coolant, I prefer to be meticulous. Ensure the car is cold and parked on a level surface, and wear protective gloves to prevent skin irritation. Open the reservoir to check the condition of the old fluid; if it appears cloudy, it needs replacement. Locate the drain valve or plug to release the old fluid, and use a container for environmentally friendly disposal. Before adding new coolant, flush the system using a bucket or hose to remove residue. Choose a coolant that matches the Haima model, mix it according to the specified ratio, and pour it in slowly to avoid overflow. Start the engine to bleed air for a few minutes, then top up to the full line and confirm there are no air bubbles. Finally, clean up the tools. Regular maintenance can extend engine life, and a DIY coolant change costs only a few dozen yuan, saving half compared to a shop service.
