To ensure optimal operation and avoid premature wear on the engine, what is the ideal operating temperature of the cooling system?

Question

DentroTest · Accepted Answer

The cooling system keeps the engine at its temperature of optimum performance, which in the coolant is around 90 ºC (between 85 and 100 ºC). Of the three options, only this one falls within that range. At too low a temperature the engine performs very poorly and uses more fuel; at too high a temperature, parts can be deformed.
