Can Coolants of the Same Color but Different Brands Be Mixed?
1 Answers
Coolants of the same color but different brands cannot be mixed. It is necessary to use the same brand of coolant, as different brands may have varying production formulas. If mixed, the multiple additives may undergo chemical reactions, rendering the additives ineffective. The method for replacing coolant is as follows: Before completely replacing the coolant, 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 coolant flows through the five-way hose and is then distributed to different parts of the car to function. If there is any leakage of coolant in this section, replace the hose or re-secure the connection based on the situation. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continue to fill the reservoir with water, allowing the 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. Initially, the water flowing out of the reservoir may have a faint pink tint. Continue adding clean water until the water coming out 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 coolant through the radiator hose. Then, add another container of coolant to the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level may drop slightly as some air is expelled from the cooling system. Add more coolant until it reaches the "MAXT" mark on the reservoir.
