What Are the Consequences of Not Adding Antifreeze to a Vehicle?

Without coolant, a car's radiator cannot effectively dissipate heat, failing to achieve proper cooling, which can lead to overheating and, in severe cases, engine damage. In cold climates, it can also cause the engine or radiator to freeze, resulting in engine failure and preventing the vehicle from starting normally. Antifreeze Replacement Method: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leaks or cracks in the pipes, with a focus on the five-way hose. The five-way hose is named for its five connections to different parts of the vehicle. Antifreeze flows through this hose and is distributed to various parts of the car to perform its function. If there are any signs of antifreeze leakage in this area, replace the hose or resecure the connections as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue filling it until water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink tint. Continue adding clean water until the outflow is clear. Note: Remember to remove the heater hose and drain the water from the heater core. 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 will drop slightly as air is purged from the system. Top up the antifreeze to the "MAXT" mark on the reservoir.
