Can I Add Pure Water If The Antifreeze Is Low?

[OLuna]

You can add pure water if the antifreeze is low. It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering them ineffective. Method for replacing antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with a particular focus on the five-way hose. The five-way hose is named for its five connection points to various parts, and the antifreeze flows through it before being distributed to different sections of the car to function. If there is any leakage of antifreeze in this area, replace the hose or resecure the connections as needed. Drain the old antifreeze and then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir, then continue filling the reservoir to allow water to flow continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially draining from the reservoir may appear slightly pinkish; continue adding clean water until the outflow is clear. Note: Remember to remove the heater hose to drain all the water from the heater. After draining for about an hour, add the new antifreeze through the radiator hose to allow it to flow quickly into the radiator. Then, add another container of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level may drop as air is purged from the system. Top up the antifreeze to the maximum mark "MAXT" on the reservoir.
