The splash shield, or engine undertray, is detached by freeing the edge fasteners—usually a mix of plastic clips and small screws—around the wheel well and along the bottom edge. In many Civic models you’ll need to remove the front wheel for easier access.
This guide outlines a practical, generation-spanning approach for Civics, highlighting common fasteners, necessary tools, and step-by-step procedures. It also notes safety considerations and model-specific variations you may encounter while working under the car.
Tools and supplies you’ll need
The following tools help you safely detach the splash shield without breaking fasteners. Gather these before you begin to minimize surprises under the car.
- Panel clip removal tool or plastic trim pry tool
- Flat-head screwdriver
- Philipps screwdriver
- Torx driver (commonly T25 or T30, depending on fasteners)
- 8mm and/or 10mm socket with ratchet
- Socket wrench and extension
- Pliers or a clip removal tool for push rivets
- Jack and jack stands or ramps
- Wheel chocks
- Gloves and a flashlight
- Replacement clips or rivets (optional but recommended in case any fasteners break)
With the right tools, you’ll reduce the risk of damaging the shield or nearby components during removal.
Step-by-step removal guide
The following steps provide a practical sequence for most Honda Civics. Some model years may use different fasteners or configurations, so adapt as needed and consult your shop manual if you have one.
- Park on a level surface, engage the parking brake, and place wheel chocks on the rear wheels. If you plan to work on the front area, consider lifting the front of the car and supporting it with jack stands for security.
- If possible, loosen the front lug nuts slightly while the car is on the ground, then raise the vehicle and remove the front wheels to gain clear access to the splash shield and wheel well area.
- Inspect the splash shield’s attachment points along the wheel well, bottom edge, and any fasteners near the bumper or radiator support. Identify plastic push rivets, Phillips or Torx screws, and any other fasteners.
- Begin removing the fasteners:
- For push rivets, pry up the center pin with a trim tool or flat-head screwdriver to release, then pull the rivet out.
- For screws, use the appropriate screwdriver or Torx bit and remove them; keep screws organized for reinstallation.
- Remove any additional fasteners along the bottom edge of the shield and along the wheel well liner.
- Gently pry the shield away from the bumper and fender clips, starting at a corner and working your way around. Avoid forcing clips or bending the shield; if a fastener breaks, replace it and continue.
- Once all fasteners are released, carefully lower and remove the splash shield from under the vehicle. Inspect the area for any remaining tabs or clips that might still be engaged.
Reinstallation is the reverse of removal. Align the shield with the mounting holes and reinsert screws or clips, ensuring a snug fit. Reinstall the wheel, torque the lug nuts to spec, and lower the car to the ground.
After completing the removal or replacement, double-check that the shield sits flush and that no fasteners interfere with wheels, suspension, or steering. If any fasteners were damaged, replace them with appropriate clips or rivets to maintain proper protection.
Generation-specific notes
The Honda Civic has several generations with slightly different fastener layouts. In recent models, you’ll typically find a combination of plastic clips and a handful of screws along the wheel well and bottom edge. Some third-party or two-piece shields may require removing additional fasteners connected to the bumper or undercarriage supports. If you’re unsure about your generation, consult the vehicle’s service manual or a reputable online guide specific to your year and trim.
Summary
Removing the splash shield on a Honda Civic involves locating and releasing the edge fasteners—typically plastic clips and small screws—around the wheel well and bottom edge, optionally removing the front wheel for easier access, and carefully detaching the shield. Reinstall by aligning holes, reattaching fasteners, and torquing hardware to spec. Always work safely under the vehicle with proper support and replace any damaged clips as needed. A careful, methodical approach minimizes damage and ensures the shield can be reinstalled properly for continued protection of the engine bay.
