What Are the Reasons for Rapid Antifreeze Loss?

[MiaLee]

There are several main reasons for rapid antifreeze consumption in vehicles: leakage; poor circulation leading to fast consumption; coolant entering the cylinder and being burned or entering the oil pan. If the rapid consumption is due to leakage, traces are usually visible at the leakage points. The solution involves replacing the radiator or tightening screws at the overflow tank, water pump joint surfaces, and cooling system pipelines. If the issue is poor circulation, it is advisable to have a professional mechanic conduct an inspection. If the coolant is entering the cylinder and being burned or entering the oil pan, it is important to check whether the engine cylinder head gasket or intake manifold gasket is damaged. If damaged, repairs or replacements are necessary. 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 antifreeze is distributed to different parts of the vehicle after flowing through it. If there is any antifreeze leakage in this section, 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 and continue filling until water flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the hoses may have a faint pink tint. Continue adding clean water until the outflowing water runs clear. Remember to remove the heater hose and drain the water from the heater core. Approximately one hour after draining, 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 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 fluid level will drop slightly. Add more antifreeze until it reaches the "MAXT" mark on the reservoir.
