About Fender Liner
The fender liner acts as a shield between the water, mud, dust and debris and the vehicle’s wheel well. It is situated between the fenders and wheels and is also known as inner fender which is made of plastic or metal. The outer fender helps is preventing the mud/sand or debris to fly away from spinning tires. The inner fender also separates the outer fender and the engine and is attached to the outer fender by clips so that it remains in proper position. The fender liner always remains exposed to nature and thus is prone to a lot of wear and tear over prolonged time. So, keep a regular check on the fender liner for replacement.
How It Works?
Although the fender liner itself does not do any mechanical or electrical work it serves as a barrier to many important components and protects them against dirt, dust, debris, and corrosion. Therefore, recognising the value of the fender liner and its functionality is important. All the different layers of the linear function as a team to secure and maintain the car's engine bay. The fender filler is made of different layers. The breathable base material layer is created by creating, along the wheel house, a fibre assembly in shape. The other protective layer in a water-resistant material. The base layer has a protective layer superimposed on top opposite to the side facing the wheel house. The protective layer has tiny holes that allow air to flow through to reach the base layer. The upper side of the tyre is covered with a fender liner applied to the wheelhouse of the motor vehicle. One may note increased noise generated from the gap between the tyres and the surface of the ground, or the noise of small rocks and debris hitting the inner fender. A fibre-based fender cover is used to prevent such a condition and is connected to the wheel house. While fibre-based liners minimise vibration, they fall short in water and ice conditions because their anti-icing performance is very poor. This can contribute to ice formation on fenders and tyres, which can cause driving difficulties. Therefore, before installing any new fender liner, it is necessary to consider the geographical terrain and climatic conditions. Internal fender liners are usually replaced with plastic from factory to provide better engine protection. In order to make the liner rust-free, anodized aluminium used in the inner lining to make it strong and light. Additionally, the black carbide powder coat used as a finishing coat to improve corrosion resistance.
