What Causes Abnormal Noise in Kia K3's Engine During Cold Start?
1 Answers
Kia K3's engine produces abnormal noise during cold start because the valves do not receive sufficient lubrication, causing the hydraulic lifters and mechanical rocker arms to malfunction. Below are relevant details: 1. Car Engine: The car engine is the device that provides power to the vehicle, acting as the heart of the car. It determines the vehicle's power, fuel efficiency, stability, and environmental performance. Some cases of abnormal noise during cold start are normal, but for safety reasons, it is recommended to get it inspected immediately. 2. Precautions: The vehicle should be driven at low speeds, with engine RPM not exceeding 3000-3500. Generally, it should be kept at around 2000 RPM; otherwise, the intense wear on the engine and transmission may become irreversible.
