What Are the Symptoms of High Engine Temperature?

[SamanthaAnn]

High engine temperature has the following symptoms: 1. Reduced cylinder air intake, leading to a decrease in engine power. For gasoline engines, it may also cause knocking. 2. Excessively high temperatures can thin the engine oil viscosity or even cause oxidation and deterioration, reducing lubrication and accelerating component wear. 3. When the temperature is too high, components expand due to heat, disrupting the normal gaps between parts and preventing them from functioning properly. 4. Excessively high temperatures can significantly weaken the mechanical properties of metal materials, causing deformation and damage to components. 5. During hot idle, the air conditioning compressor clutch engages and disengages frequently or even disconnects, resulting in the air conditioning not cooling when the engine is hot.
