the cooling system is responsible for maintaining the optimum temperature of the engine and is designed to avoid exceeding the maximum temperature level of 150°c. ideal engine temperature is 90-100°c. indirect cooling, i.e. cooling with a liquid that flows through channels built into the engine block, is the most common cooling method in motor vehicles. the fluid returning from the engine compartment returns through the thermostatic valve chamber, which, depending on the temperature of the fluid, directs it directly to the radiator for cooling or directly to the pump and engine channels. coolant concentrate is a condensed substance that combines with water to form coolant.
using only water in the cooling system can cause engine failure due to overheating, as water does not have the appropriate properties. a complete lack of fluid can cause the engine to overheat or even seize. the coolant should be checked at least once a month. its amount can be checked in the coolant reservoir under the hood.
