Why do 4S shops replace with waterless coolant?

[DiJohnny]

4S shops replace with waterless coolant to ensure vehicle safety, as it can replace conventional coolant. Here is an introduction to waterless coolant: 1. Introduction: Waterless coolant, also known as waterless cooling oil or automotive cooling oil, is a new type of automotive consumer product and a 'revolution' in automotive history. 2. Function: It completely eliminates the long-standing issues of corrosion, scale, cavitation, and overheating in the cooling system caused by traditional coolant, thereby extending the engine's lifespan. 3. Prospects: With the rapid advancement of human technology, the continuous pursuit of improved engine performance, and the increasing awareness of environmental protection, waterless coolant will replace water-based coolant and have broader prospects.

Last time I had my car serviced at the 4S shop, the technician recommended switching to waterless coolant, mainly because it's more worry-free to use. With regular coolant, I had to periodically check and top up the water level. If it leaked or boiled over, the engine could easily develop problems. The waterless version has a boiling point over 190°C and an ultra-low freezing point, so there's no worry about freezing cracks in winter or engine overheating in summer. It's especially suitable for someone like me who frequently drives long distances. The 4S shop mentioned it has a patented formula that reduces corrosion and rust, extending the radiator's lifespan and saving on repairs in the long run. It is a bit more expensive, but they cover installation and after-sales service, saving me time and effort. After using it, I noticed the car's cooling system is more stable, and the noise has decreased. If the budget allows, it's worth trying.

As someone with some knowledge about cars, I find the technical advantages of waterless coolant quite obvious. Conventional coolants contain water, which can easily boil at high temperatures or freeze at low temperatures, damaging metal components. In contrast, the waterless type uses organic liquids to replace water, with a boiling point nearly 50 degrees higher and a freezing point as low as -50 degrees Celsius, offering better protection for the engine block and radiator. 4S shops recommend it because it reduces failure rates, such as preventing leaks and corrosion issues. After switching, my maintenance intervals have extended, reducing frequent visits to the shop. Of course, this product comes at a higher cost, and it's common for 4S shops to make some profit. But overall, it enhances the car's reliability and environmental friendliness, which is a good thing for those who prioritize efficient travel.

I chose the waterless coolant when getting it replaced at the 4S shop, aiming for long-term cost and hassle savings. While regular coolant is cheaper, it requires frequent checks and top-ups with water. Neglecting this could lead to pipe corrosion or water pump failure, with repairs costing hundreds. The waterless formula contains no water, directly preventing rust and sediment buildup, extending engine life by several years. The 4S shop promotes it partly due to higher profits, but I find it worthwhile—reducing maintenance frequency saves me significant labor costs over a year. It's especially suitable for seasoned drivers like me who prioritize reliability and low risk.
