Installing fender covers during engine work serves the important purpose of preventing paint damage. When working on an engine, tools and equipment can inadvertently strike the car’s fenders, or fluids may spill, leading to scratches, dents, or stains that can be difficult to remove. Fender covers provide a protective barrier that safeguards the vehicle's paint and finish, maintaining its aesthetic integrity. This is particularly vital in professional settings where vehicles are valued not only for their functionality but also for their appearance.

While options such as improving visibility and enhancing air circulation involve important aspects of vehicle maintenance, they do not address the specific protective benefits that fender covers provide during hands-on repairs. Similarly, stabilizing engine components is more aligned with mechanical support rather than preventing cosmetic damage to the vehicle’s exterior. Thus, the primary function of fender covers is indeed to protect against paint damage, making that the correct answer.
