Can diesel vehicles and cars use the same antifreeze?
2 Answers
Diesel vehicles and cars can use the same antifreeze because automotive antifreeze is not differentiated between gasoline and diesel vehicles. However, when using antifreeze, it is essential to ensure that the freezing point of the antifreeze is not higher than the lowest temperature in the applicable region. It is advisable to use the same brand of antifreeze and avoid mixing different brands. Antifreeze prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block. Its full name is antifreeze coolant. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year.
I remember a few years ago when I was driving a diesel truck, I tried to save money by using car antifreeze. As a result, the engine temperature skyrocketed and nearly got ruined. Later, I learned that diesel engines operate at much higher temperatures and require specially formulated antifreeze, such as additives to resist boiling and corrosion, unlike the simpler antifreeze used in cars. If you use the wrong type, deposits can build up in the system, leading to clogging and rust in the water pump—repair costs could be ten times more expensive than buying the right antifreeze. Now, when I buy a car, I strictly follow the manual’s specified type and replace it regularly to maintain good condition. It saves both hassle and money, especially in winter—never take the risk.
