What is the function of Radiator Coolant?

[VonAmir]

Radiator Coolant functions: Helps prevent automobile engine overheating, providing summer anti-boiling, winter antifreeze, year-round anti-corrosion, anti-scale, anti-rust, and anti-foaming effects. It offers protection for cast iron parts, brass, copper, aluminum alloy, solder, and rubber components. It is also compatible with any antifreeze or cooling water. Radiator Coolant: The difference between Radiator Coolant and antifreeze lies in their freezing points. Radiator Coolant is an additive primarily used in antifreeze coolant to clean scale deposits in the radiator and cylinder block. Antifreeze: Antifreeze is added to the radiator to provide antifreeze and heat dissipation functions. Although their compositions are largely similar with minimal efficacy differences, Radiator Coolant has a higher freezing point than antifreeze, making it more prone to freezing when used alone. Therefore, using antifreeze is more recommended.

I've been driving for over a decade, and coolant has been a great help. It's mainly added to the cooling system to prevent freezing in winter and boiling in summer, protecting the engine from freeze damage or overheating. This stuff is much better than tap water—it doesn't leave scale deposits in the pipes and also prevents rust and corrosion on metal parts. Last winter when I was on a business trip to Northeast China, my car was parked outside overnight at temperatures below -20°C. Thanks to the antifreeze coolant, the engine didn't freeze. For regular maintenance, it's recommended to replace it every two years, making sure to choose the correct type by color, as mixing different types can cause reactions. Oh, and remember to check the coolant level regularly and top it up when low—otherwise, uncontrolled engine temperature can cause serious trouble.

As a regular customer at auto repair shops, I deeply understand the importance of coolant. Essentially, it's an antifreeze coolant with three key functions: antifreeze, anti-boil, and anti-corrosion. Regular water can freeze and expand in winter, potentially bursting the radiator, and it's prone to boiling at high temperatures. In contrast, coolant has a freezing point as low as -40 degrees and a boiling point up to 130 degrees. Even more impressive is its ability to protect the entire cooling system from rust, especially metal components like the water pump and radiator. Last time my car consistently ran at a higher temperature, the mechanic diagnosed it as poor cooling due to ineffective coolant. It's recommended to replace it periodically as per the maintenance manual. Different colored coolants have different compositions, so avoid mixing them. Opting for reputable brands ensures better quality.

Novice drivers may not fully understand the purpose of coolant. Simply put, it's a specialized fluid that protects the engine's cooling system, performing far better than plain water. During scorching summers, it prevents coolant from boiling over; in freezing winters, it avoids ice formation that could burst pipes. Even better, it inhibits rust and corrosion on metal components, extending engine life. I used to think regular water would suffice, but my radiator rusted and leaked within just six months. Now I change the coolant every 2 years and recommend opting for long-life formulas for hassle-free maintenance. Always keep the coolant reservoir level between the MIN/MAX marks, and top up with the same color if low.
