Usual Indications of a Worn Mazda Millenia Splash Shield
Your splash shield located on the inner fender is designed to block water and road debris from entering the engine bay and car's underbody. Commonly called as "inner fender liner," this shield also functions as a road noise dampener which reduces the sound caused by the contact of the tire with the road. Your splash shield is prone to wear and tear, and you should be aware when it is already going south. Following are some signs:
Over time, because of servicing, repair, and preventive maintenance done on the engine bay, fender, and wheels, your splash shield deforms. When this occurs, parts of your splash shield are moved out of its place. Because of this, since it is located just above the wheel, it tends to rub with the tire when the vehicle is turning or running. Once this occurs, your splash shield melts because of the friction and heat it makes with the tire.
Dirty engine bay
If you notice that your engine bay has gotten dirty on the left, right, or both sides, one or both of your splash shields may have gotten bad. The inner fender liner is the engine bay's main protection against different elements on the road while your car is running. However, your splash shield tends to get worn over time to the point where it rubs with the tires of your car. When this happens, the shield material becomes burned and shredded, allowing the road elements to enter your engine bay.
Inner fender noise
Your Mazda Millenia splash shield is located at the inner fender well of your car. Aside from blocking elements from the road, it also eliminates wheel noise. However, since the shield is prone to different vibrations, its mounting clips tend to go loose, resulting in a misplaced shield. When this happens, it would not function as well as it should be, resulting in more noise and vibrations from the inner fender.
Another sign that your Mazda Millenia splash shield is dislocated is a burning smell on the inner fender. The odor is caused by the rubbing of the plastic shield and the rubber tire. It is more apparent when you are driving at high speed. When you notice the smell, the fender is the first part you need to look at.
