Can I add antifreeze by myself?
2 Answers
You can add antifreeze by yourself. The method to add antifreeze yourself is as follows: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the antifreeze; 2. Insert a rubber hose connected to a tap into the radiator filler port; 3. Turn on the tap to allow tap water to continuously flow through the engine cooling system; 4. During the flushing operation, keep the engine idling until clear water comes out of the radiator; 5. Add antifreeze to the radiator. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze function. Its role is to prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the vehicle is parked in cold winter.
Of course you can add coolant by yourself. With twenty years of driving experience, I can tell you it's simple and cost-effective. First, make sure the car is completely cooled down to avoid getting scalded by hot water. Then, pop the hood and locate the radiator cap—usually a large plastic cover. Unscrew it and check the fluid level. If it's below the minimum line, pour in some coolant, preferably the same color or brand as the original to avoid chemical reactions from mixing different types. Remember to start the engine for a few minutes after adding to let the fluid circulate and balance. Doing it yourself saves you dozens of dollars in repair fees, but if the level keeps dropping, there might be a leak in the radiator or an engine issue, so get it checked by a professional promptly. Develop a habit of regular checks, like inspecting the fluid level every season change, to prevent minor issues from turning into major problems.
