Does the new Highlander have two places to add coolant?
1 Answers
Highlander has two places to add coolant. One is for the intercooler coolant of the engine; the other is for the turbocharger coolant. Definition of coolant: Coolant, the full name should be antifreeze coolant, meaning it has antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold seasons. Coolant consists of three parts: water, antifreeze, and additives. According to different antifreeze components, it can be divided into alcohol-based, glycerol-based, ethylene glycol-based, and other types of coolant. Coolant replacement cycle: Replace it every two years because the effective period of coolant is two years. Expired coolant can cause cylinder corrosion, and in severe cases, it may even cause serious damage to the engine. In addition, the freezing point of coolant is generally around -25 degrees Celsius. If you go to colder places, you need to replace it with antifreeze with a lower freezing point. Of course, this is just a reference replacement cycle. It can be replaced according to actual usage conditions because driving an extra ten thousand kilometers or extending the usage period by about a year or so is not a big problem. If the car is used intensively, it can be replaced in advance.
