Which outcome occurs when a gasoline engine's coolant system fails, causing sustained high operating temperatures?

💡 Explanation

When the coolant system fails, internal engine components overheat because heat transfer is reduced, causing increased component temperatures, which reduces oil viscosity and lubrication effectiveness. Therefore decreased oil viscosity results, rather than pre-ignition, increased valve pressure, or reduced air density, all of which involve alternate mechanisms.
