Step-by-Step Installation Guide
-
Prepare Your Vehicle: Park your Nissan Frontier on a level surface, engage the parking brake, and securely chock the rear wheels. Use the jack and jack stands to safely lift the front of your vehicle, providing enough clearance to work comfortably underneath.
-
Locate the Existing Splash Shield: The splash shield is located beneath the engine, protecting vital components from road debris. Inspect it carefully to understand how it's attached.
-
Remove the Old Splash Shield: This usually involves removing several bolts and fasteners. Use your socket wrench and ratchet to carefully loosen and remove each one. Take note of their locations and placement for easy reassembly. Some fasteners may be difficult to access; extension bars will be helpful here. Be gentle to avoid stripping the bolt threads.
-
Clean the Mounting Area: Once the old splash shield is removed, thoroughly clean the mounting area on the vehicle's undercarriage. Remove any dirt, debris, or rust that could interfere with the new shield's installation.
-
Install the New Splash Shield: Align the new splash shield (P/N 50842-7S000) with its corresponding mounting points. Carefully install the bolts and fasteners, ensuring they are tightened securely but not over-tightened. Refer to the previous step to remember the bolt locations.
-
Lower Your Vehicle: Once the new splash shield is securely attached, carefully lower your vehicle using the jack and jack stands. Double-check all the fasteners to make sure everything is tightened correctly.
