Can I Change the Car Coolant Myself?

[McJude]

You can change the car coolant yourself by following these steps: 1. First, wait for the vehicle to cool down. Never replace the antifreeze when the engine is at a high temperature. 2. Drain the old coolant. There are several methods for draining. Once the original coolant is completely drained, you can add new coolant. 3. If the new antifreeze is not the same brand as the original one, the formula may differ. When switching to a different brand of antifreeze, it's necessary to flush the cooling system to prevent chemical reactions between the two different formulas, which could corrode metal components. 4. Some engine models have a drain valve. Opening it allows the antifreeze in the engine to be completely drained. If you need to clean the radiator, reassemble the pipes, fill the radiator with water, and you may add a cleaning agent if necessary. 5. Start the vehicle. When the water temperature rises and the electric fan starts, turn on the heater to allow the small radiator to circulate. After circulating for a while, turn off the engine. Once the water temperature drops, completely drain the water.
