Do You Need to Replace Coolant in Hot Weather?
1 Answers
Hot weather does not necessitate coolant replacement, as coolant change is not related to weather conditions. For vehicles that operate for extended periods, such as taxis, high-quality coolant should generally be replaced annually. Vehicles with shorter operating hours can have their coolant replaced every two years or every 30,000 kilometers. How to Replace Coolant: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leaks or cracks in the pipelines, with a particular focus on the five-way hose. Coolant flows through the five-way hose and is then distributed to different parts of the car to function. If there are any signs of coolant leakage in this area, replace the hose or resecure the connection as needed. Drain the old coolant and then flush the fluid channels with clean water. Add clean water to the coolant reservoir and continue to fill 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 draining from the reservoir will have a faint pink tint. Continue adding clean water until the drained water runs clear. Note: Remember to remove the heater hose and drain all water from the heater core. Approximately one hour after draining, add new coolant through the radiator hose. Then, pour another container of coolant into the coolant 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 coolant level will drop slightly. Top up the coolant until it reaches the "MAXT" mark on the reservoir.
