The plastic underbody cover of a car, also known as a splash shield or skid plate, plays a vital role in protecting your vehicle’s engine and other components from debris, water, and environmental damage. Over time, you may need to remove this cover for maintenance, repairs, or inspections. This guide provides a step-by-step approach to safely and efficiently remove the underbody plastic cover while minimizing the risk of damage.
Why Remove the Plastic Underbody Cover?
The underbody cover needs to be removed for various reasons, including:
- Oil Changes: Accessing the oil drain plug and oil filter.
- Repairs: Reaching specific parts of the engine or suspension.
- Inspection: Checking for leaks, corrosion, or damage underneath the vehicle.
Knowing how to properly remove and reinstall this component is a valuable skill for any car owner.
Tools Required
Before starting, gather the following tools to make the process easier:
- Flat-Head Screwdriver: For prying up plastic clips.
- Phillips-Head Screwdriver: For screws with cross-head designs.
- Socket Wrench Set: Commonly used sizes include 10mm and 12mm.
- Plastic Fastener Removal Tool: Ideal for removing clips without breaking them.
- Safety Gloves and Glasses: To protect your hands and eyes during the process.
Step-by-Step Process
1. Prepare the Vehicle
- Park the car on a flat, stable surface and turn off the engine.
- Engage the parking brake and, if necessary, raise the vehicle using a jack. Secure it with jack stands for stability.
2. Locate Fasteners
Inspect the edges of the underbody cover to identify all fasteners, which may include screws, bolts, and plastic clips. Dirt or debris might conceal some fasteners, so cleaning the area may help reveal them.
3. Remove Plastic Clips
- Use a flat-head screwdriver or plastic fastener removal tool to pry up the center portion of each clip.
- Once the center is released, pull out the entire clip.
- Be gentle to avoid breaking reusable clips.
4. Unscrew Bolts and Screws
- Use the appropriate socket wrench or screwdriver to remove all bolts and screws holding the cover in place.
- Keep track of each fastener, as they may vary in size and placement.
5. Detach the Cover
- After removing all fasteners, carefully lower the cover.
- Some covers may have hooks or tabs that require sliding or maneuvering to release.
- If the cover is large, seek assistance to avoid accidental damage.
6. Inspect and Proceed
- With the cover removed, inspect its condition for cracks or wear. Replace it if necessary.
- Proceed with your maintenance task, such as an oil change or inspection.
Common Challenges and How to Overcome Them
- Stubborn Fasteners: Corrosion or grime can make clips and screws difficult to remove. Apply a penetrating lubricant to loosen them.
- Stripped Bolts or Screws: Use a screw extractor tool to handle stripped fasteners.
- Misaligned Reinstallation: Start all fasteners loosely before tightening to ensure proper alignment.
Tips for Reinstallation
Reattaching the plastic underbody cover requires careful attention to ensure a secure fit:
- Align the Cover: Ensure all tabs and hooks are in place before securing fasteners.
- Replace Damaged Fasteners: Use new clips or screws if the old ones are broken or worn.
- Torque Bolts Properly: Tighten bolts to the manufacturer’s specified torque to avoid over-tightening or loosening.
Comparison of Fastener Types
| Fastener Type | Description | Removal Tool |
|---|---|---|
| Plastic Push Clips | Common for lightweight panels. | Flat-head screwdriver |
| Phillips-Head Screws | Standard screws for versatile use. | Phillips-head screwdriver |
| Hex Bolts | Heavy-duty attachment for stability. | Socket wrench (e.g., 10mm) |
Safety Precautions
- Wear Protective Gear: Always use gloves and safety glasses.
- Use Stable Support: If lifting the car, ensure jack stands are secure.
- Avoid Rushing: Take your time to avoid damaging clips or scratching the underbody.
Why Proper Removal Matters
Incorrect removal of the plastic underbody cover can lead to:
