Is it necessary to install a car bug screen?

It is not necessary to install a car bug screen. A car bug screen is a very fine protective mesh. After installation, it will inevitably affect the radiator's air-cooling efficiency, leading to reduced heat dissipation performance of the radiator and potentially causing the radiator temperature to rise excessively, even to the point of overheating. The car bug screen is located at the front of the vehicle's radiator frame and is installed as an outer protective layer over the radiator. Its main purpose is to block leaves, insects, gravel, and other debris from passing through the front bumper gaps and hitting the radiator, thereby protecting the radiator from damage and keeping it clean. If a car bug screen is installed, the owner should regularly remove and clean the protective mesh to prevent excessive accumulation of debris, which could impair the radiator's heat dissipation.
I've been driving long distances frequently in recent years, and the highways are swarming with bugs like rain. Last time, the radiator fins were completely clogged with dead insects, and it took the car wash over half an hour with a high-pressure water gun to clean them out. After installing a bug screen, it’s been much easier—the mesh catches about 90% of the bugs, and cleaning is just a quick spray with the water gun during a car wash. Opt for a nylon screen to avoid rust, and make sure the mounting clips are stainless steel. Although it might slightly reduce airflow, it’s nothing compared to the hassle of cleaning the radiator, especially when driving on rural dirt roads where the effect is even more noticeable.
City drivers who are used to urban driving might think it's unnecessary, and I used to think the same way. However, after a couple of trips to the suburbs in summer, I changed my mind. The worst fear is tiny insects getting stuck in the radiator fins and rotting, which can corrode the aluminum over time. But there are two things to note when installing: don’t buy the cheap, low-quality mesh that costs just a few bucks, as it tends to become brittle and shed debris. Also, driving at low speeds in the city can actually reduce cooling efficiency—I tested it and found that with the mesh installed, the water temperature rose by two or three degrees in traffic jams. Later, I specifically designed removable clips for it.
