Why is it important for the oil cooler to maintain the oil at an optimal temperature range?
To ensure the oil maintains proper viscosity for lubrication.
An oil's viscosity is strongly temperature dependent: if the oil gets too hot it thins out and the protective film breaks down, and if too cold it is too thick to flow and circulate.
The oil cooler removes excess heat and holds the oil within its designed temperature band so it keeps the correct viscosity to form a proper lubricating film between moving parts.
The oil cooler does not cool combustion gases and does not change the oil level, so those options are unrelated.
Hence, the oil cooler maintains temperature to ensure proper viscosity for lubrication.
