How to Add Coolant to a Car?

[Penny]

Steps to add coolant to a car: 1. Ensure the engine is in a cold state; 2. Open the hood and locate the engine's coolant reservoir; 3. Turn the reservoir cap counterclockwise to open it, then open the drain valve to flush and clean the interior; 4. Directly refill the reservoir with the same specification of coolant until the liquid level reaches the maximum mark; 5. After filling, securely close the reservoir cap. The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties to prevent the coolant from freezing during cold seasons, which could otherwise crack the radiator or damage the engine block. Antifreeze is not just for winter use; it should be used year-round. As part of regular car maintenance, the engine antifreeze should be replaced once every year.
