How often should the coolant be replaced in a Volkswagen Lavida?

Volkswagen Lavida requires coolant replacement every 2 years or 40,000 kilometers. During replacement, the old coolant should be completely drained, the cooling system thoroughly cleaned, and then new coolant added. Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems, offering excellent properties such as antifreeze protection in winter, anti-boiling in summer, and year-round protection against scale and corrosion. The Volkswagen Lavida is a compact sedan with dimensions of 4605mm in length, 1765mm in width, and 1460mm in height, with a wheelbase of 2610mm. The car's onboard navigation system features a combination of touch screen and knob controls, along with MP3 playback capability, supporting USB, AUX, and SD card expansion slots.

I drove a Volkswagen Lavida for over five years, so I'm quite familiar with it. The official maintenance manual states that the coolant should be replaced every two years or 40,000 kilometers. I think this really shouldn't be delayed. Last summer, my friend's car overheated on the road because the coolant had expired. When replacing it, it's best to go to a professional shop—they can test the freezing point and concentration. Usually, just keep an eye on the fluid level; as long as it's between the min and max marks, it's fine. If you notice the coolant turning black or forming flocculent matter, don't hesitate—replace it immediately. It's also a good idea to check it before winter. Aged coolant loses its antifreeze effectiveness, and in temperatures below -10°C, it can easily freeze and crack the pipes. Replacing an engine could cost tens of thousands.

Speaking of changing coolant, I've worked on quite a few Lavidas. Most owners can change it every two years, and if the mileage is low, stretching to three years is barely acceptable. Last time, there was a car that hadn't changed its coolant for six years, and the radiator was full of rust particles. When changing, don't just top up the liquid; you need to flush the entire cooling system. The color of the coolant fading is a sign of failure—if it changes from blue or green to pale yellow, it's time for a change. Pay special attention in hot weather; degraded coolant has a lower boiling point, and the temperature gauge will rise quickly when climbing a slope. It's recommended to check before summer starts. Spending twenty dollars at a repair shop to test the freezing point is much more cost-effective than breaking down halfway.

My first Lavida has been running for seven years now. Initially, I changed the coolant every 40,000 kilometers for the first two times. Recently, I switched to changing it every 30,000 kilometers, especially since summers in the south are quite hot. I discovered a trick: during maintenance, ask the mechanic to test the parameters with a refractometer. If the readings are normal, you can extend the usage by another six months. When washing the car, take a moment to wipe the scale on the expansion tank; accumulated dirt can obscure visibility. Remember, the original coolant is from the G12 series, and mixing different types can risk crystallization. A change costs about three to four hundred, but that's small change compared to an engine overhaul. In winter, check for pink stains on the ground before starting the car—it's a sign of leakage.
