Question 736 of 1208

The temperature of the coolant which ensures maximum performance and minimum engine wear is within the range:

A 100-120 degrees C;
B 60-70 degrees C;
C 90-95 degrees C.

Explanation

The temperature of the coolant which ensures maximum performance and minimum engine wear is within the range of 90-95 degrees Celsius.

The engine cooling system has the role of ensuring an optimal engine temperature (90-95 degrees Celsius). The temperature inside the engine can reach 2000° C at the moment of combustion. Therefore cooling is necessary to avoid excessive expansion of the parts, which would generate the blocking (seizure) of the engine.

The correct answer is: C
