How Many Bottles of Antifreeze Are Needed to Replace It in a Car?

Replacing the antifreeze in a car requires about 5 bottles. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking. Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connecting interfaces to various parts. Antifreeze flows through the five-way hose and is distributed to different parts of the car to function. If there is any antifreeze leakage in this section, replace the hose or resecure the interface as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir, then continuously inject water into the reservoir to allow it to flow through the engine cooling system. Start the car and let it idle for 3 to 5 minutes to circulate the water. The water initially draining from the reservoir will have a faint pink color. Continue adding clean water until the outflowing water is clear. Remember to remove the heater hose and drain the water from the heater core. About an hour after draining, add the new antifreeze through the radiator hose to allow it to flow quickly into the radiator. Then, add another bottle of antifreeze to the antifreeze reservoir until it is nearly full. Start the car and let it run for about 10 minutes. During this time, the coolant level will drop slightly as air is expelled from the cooling system. Add more antifreeze until it reaches the "MAXT" mark on the reservoir.
