What brand of antifreeze does the Lincoln MKZ use?
2 Answers
Lincoln MKZ uses original factory-specific antifreeze. Method for replacing antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way water pipe. The five-way pipe is named for its five connection points to various parts, and antifreeze flows through it before being distributed to different sections of the car to function. If there is any antifreeze leakage in this part, replace the water pipe 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, then continue adding water to ensure it 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 draining from the reservoir may have a faint pink tint. Keep adding clean water until the outflow is clear. Note: 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 container of antifreeze to the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As the cooling system expels some air, the fluid level will drop. Top up the antifreeze until it reaches the "MAXT" mark on the reservoir.
I've been driving a Lincoln MKZ for several years and always use Motorcraft brand coolant, which is specifically designed for Ford vehicles, especially the orange 50/50 pre-mixed formula that perfectly matches the engine materials. The owner's manual recommends this brand for its stable anti-corrosion and temperature control performance, with a replacement cycle of about every two years or 30,000 kilometers. I've also tried compatible brands like Prestone Dex-Cool, which performed well, but it's crucial to ensure the colors match to avoid mixing and prevent sediment buildup that could clog the system. I usually check the coolant level monthly when the engine is cold for safety. When doing a DIY coolant change, flushing the system is essential, while getting it serviced at the dealership is more convenient but costlier. Coolant isn't just for preventing freezing in winter—it also helps cool the engine and maintain performance in summer. Don't neglect regular maintenance to prevent unexpected breakdowns.
