Does the waterless coolant need to be replaced?
3 Answers
Waterless coolant does not need to be replaced. Although the heat dissipation performance of waterless coolant is indeed excellent, ordinary coolant can already meet normal heat dissipation requirements. Moreover, the cost of replacing waterless coolant is significantly high—replacing it once is nearly equivalent to the cost of replacing ordinary coolant ten times, making it not cost-effective. Here are the relevant features: Anti-corrosion: Prevents internal engine rust, keeping the radiator and cooling system as good as new. No or extremely low pressure: The cooling system operates under no or extremely low pressure, allowing the radiator cap to be opened at any time. Enhanced power: Eliminates the vapor insulation layer, resolves local overheating of the engine, releases engine power, shortens acceleration distance, makes acceleration smoother, and ensures smoother gear shifting.
I'm the kind of car owner who's obsessed with automotive details, especially the cooling system. Waterless coolants, like those from Evans, claim to be maintenance-free because they contain no water and have a high boiling point and low freezing point, avoiding the evaporation and freezing issues of traditional coolants. Theoretically, they can last a long time, even a lifetime, but this depends on the vehicle's operating conditions. For example, if your car frequently runs long distances or operates in high-temperature areas, the coolant may degrade due to oxidation or contamination buildup. If not replaced, this could lead to engine overheating or even severe damage, which would be counterproductive. I recommend regularly checking the coolant's color and level—if it becomes cloudy or falls below the indicator line, it's time for a change. Overall, waterless coolants are convenient, but occasional monitoring is essential for your car's health.
As an enthusiast who often tinkers with cars, I have to say this. The design of waterless coolant is indeed appealing—no need for regular changes like conventional coolant, which saves a lot of hassle. Its key advantages lie in its high boiling point and low maintenance requirements, unlike water-based types that can corrode the system. However, after prolonged use, you might notice it accumulating dust or getting dirty, which is when you should consider replacing it to avoid increased engine overheating risks. From my personal experience: generally, after driving 50,000 to 60,000 kilometers, check the coolant's condition; if it appears dark or the cooling performance deteriorates, don’t hesitate—replace it. Of course, don’t forget to compare it with the manufacturer’s manual recommendations. In short, the no-replacement feature is a highlight, but proactive prevention is key to ensuring safety.
