Reasons for High Engine Temperature After Oil Change
2 Answers
Engine temperature may rise due to factors such as insufficient coolant, clogged cooling radiator, or increased resistance in coolant circulation caused by scale or debris in the radiator. Increase in external unreasonable loads: For example, brake drag caused by faulty car brakes. Therefore, when noticing insufficient engine power, reduced vehicle speed, or poor acceleration, external influencing factors should be analyzed and identified. After eliminating the impact of external factors, internal causes should be investigated. Improper adjustment: Due to incorrect installation or adjustment of the throttle linkage, the governor load control lever cannot be pushed to the full-load position, thereby affecting engine power output.
As a new driver, I was really scared when my engine kept overheating after the last oil change. It wasn't until I asked a friend that I learned it might be due to using the wrong oil type. For example, in summer you should use thinner oil, while thicker oil can lead to poor heat dissipation. Or maybe the oil was overfilled or underfilled - you can check this with the dipstick. Too much oil puts extra load on the engine causing overheating, while too little increases friction and heat. Poor quality new oil could also cause faster heating since inferior oil has worse lubrication. It's recommended to check both the quantity and type after changing oil to ensure they match the manual. Keep an eye on the temperature gauge while driving, and if it overheats, pull over immediately - don't push it. Better visit a professional repair shop quickly to avoid engine damage. Driving at high temperatures also affects safety, so slow down before stopping to reduce load.
