What are the drawbacks of Evans Waterless Coolant in the US?

Evans Waterless Coolant currently has the issue of a relatively long filling time and workflow. Compared to conventional coolant, it is more troublesome to replace and requires more complex procedures. Below is relevant information about coolant: Introduction: Coolant, fully known as antifreeze coolant, refers to a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing during cold seasons when the vehicle is parked, which could otherwise cause the radiator to crack and damage the engine cylinder block. Product Performance: Coolant consists of three components: water, antifreeze, and additives. Depending on the antifreeze component, it can be classified into alcohol-based, glycerol-based, ethylene glycol-based, and other types of coolants. Alcohol-based coolant uses ethanol (commonly known as alcohol) as the antifreeze agent. It is inexpensive, has good fluidity, and is simple to prepare, but it has a relatively low boiling point, is prone to evaporation loss, has an easily elevated freezing point, and is flammable.
I previously used Evans Waterless Coolant and found several major issues. First, the price is too high—a single bottle costs several hundred yuan, several times more expensive than regular coolant, making a full replacement quite costly. Additionally, the installation is troublesome. You must thoroughly flush the car's cooling system, or any residual water mixed in can cause corrosion or engine overheating. I once tried cleaning it myself and almost didn’t get it completely clean, causing the temperature gauge to spike into the warning zone. Moreover, its performance in extreme cold weather is mediocre. Although it’s marketed as having excellent antifreeze properties, real-world testing showed it starts freezing below -20°C in winter, making it less flexible than water-based coolants. Maintenance is also inconvenient—there’s no color indicator for leaks, requiring professional tools for inspection, and repair shops may not even know how to handle it. Overall, unless you’re a performance car enthusiast, regular coolant is more practical and cost-effective.
As a seasoned driver with over 20 years of experience, I find the drawbacks of Evans Waterless Coolant quite concerning. The biggest headache is safety - the entire cooling system must be thoroughly flushed before switching to it. Improper operation leaving residual water can cause violent expansion or even engine damage. My neighbor's car had this issue, costing over a thousand in repairs. Then there's the high cost - a single refill costs as much as several years' worth of conventional coolant, making it poor value for family vehicles. Additionally, it's prone to freezing in very cold areas, unlike standard coolant that protects down to -40°C, requiring extra caution for winter use in northern regions. Leak detection is also tricky - this colorless, odorless fluid's minor leaks are hard to spot, and prolonged leakage affects vehicle performance. Personally, I still prefer traditional coolant for its reliability.
