What are the causes of high engine oil temperature?

[VanOwen]

High engine oil temperature may be caused by the following reasons: 1. Insufficient oil level or excessively high oil level. 2. Malfunction of the oil pump or insufficient oil pumping. 3. Excessive cooling water temperature. 4. Clogged oil cooler. 5. Clogged oil filter. Here are the solutions: 1. For insufficient oil level or excessively high oil level: Solution: Ensure the engine has the correct amount of oil. The oil level should ideally be between the upper and lower marks on the dipstick—neither too high nor too low. 2. For oil pump malfunction or insufficient oil pumping: Closely monitor the oil pressure gauge to ensure the oil pump is functioning properly. If the oil pump is faulty, it is recommended not to attempt disassembly or repair yourself; instead, seek professional repair services. 3. For excessive cooling water temperature: Solution: Regularly inspect key components of the cooling system, such as the water pump and oil cooler, to ensure the engine's cooling system operates normally. 4. For a clogged oil cooler: Solution: Regularly check the oil cooler and repair or replace it promptly if issues are found. 5. For a clogged oil filter: Solution: Clean the oil filter regularly and replace the filter element to ensure it functions properly.
