How to Replace the Coolant in a Haval H2?
2 Answers
Haval H2 coolant replacement method 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 a special focus on the five-way water pipe. The five-way pipe gets its name from having five interfaces that connect to various parts. The coolant flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any sign of coolant leakage in this part, replace the water pipe or re-secure the interface as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continue to pour water into the reservoir to allow it to continuously flow through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out of the reservoir may have a faint pink color. Continue adding clean water until clear water flows out. Note: Don’t forget 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, which allows the coolant to flow into the radiator quickly. Then, add another bottle of coolant to the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is purged from the cooling system. Add more coolant until it reaches the "MAXT" mark on the reservoir.
I just changed the coolant for my Haval H2 by myself yesterday, and the steps were quite straightforward. First, park the car on a level surface, turn off the engine, and let it cool for at least half an hour to avoid burns. Then, slowly release pressure by opening the radiator cap, locate the drain plug or hose at the bottom, and use a wrench to loosen it, draining the old fluid into a bucket. Once the old fluid has completely drained, flush the system with distilled water two or three times until the water runs clear, ensuring no residue remains. Next, pour in new coolant up to the MAX line, replace the cap, start the engine, and turn on the heater to let the fan run and remove air bubbles, topping up the coolant as needed. Finally, check all hose connections for leaks, and remember to use the right coolant—choose an ethylene glycol type that matches the Haval model, avoid mixing colors, and generally replace it every two years for peace of mind and cost savings.
