What Are the Consequences and Causes of Excessive Engine Oil Temperature?

[LeMakayla]

Possible causes of excessive water temperature include coolant leakage, thermostat failure, or excessive scale buildup in the water passages affecting heat dissipation. Once the water temperature rises, it can cause the water to boil, generating bubbles, which similarly leads to poor engine cooling. The consequences of excessive engine oil temperature are outlined below: 1. Consequence One: Poor heat conduction can lead to localized overheating, particularly in components far from the radiator along the coolant circulation path or with weak structural integrity, potentially causing localized deformation, cracks, or burn damage. 2. Consequence Two: It reduces the viscosity of the engine oil, leading to oil burn-off and the breakdown of the lubricating film in engine parts, accelerating component wear. In severe cases, it can result in bearing seizure or cylinder scoring. 3. Consequence Three: High engine temperature can also cause premature combustion of fuel injected into the cylinders, reduced compression force, decreased power output, potential component seizure due to overheating, and a significant reduction in bearing performance, among other adverse effects.
