What You'll Learn
Tools needed for removal
When preparing to remove the plastic engine cover on a Subaru Legacy GT, having the right tools is essential to ensure a smooth and efficient process. The primary tool you’ll need is a socket wrench set with various sizes, as the engine cover is typically secured with bolts or nuts that require specific socket sizes. A 10mm socket is commonly used for this task, but it’s a good idea to have a range of sizes (e.g., 8mm, 10mm, 12mm) to accommodate any variations in bolt sizes. Additionally, a ratchet handle with an extension bar can provide the necessary leverage and reach, especially if some bolts are located in tight spaces.
Another crucial tool is a screwdriver set, including both flathead and Phillips head screwdrivers. While most Subaru Legacy GT engine covers are primarily secured with bolts, some models may have additional screws or clips that need to be removed. A trim removal tool or a pry bar with a plastic edge can also be useful for gently prying off any clips or panels that may be holding the cover in place. These tools help prevent damage to the plastic cover or surrounding components during removal.
For added convenience, a magnetic parts tray is highly recommended to keep bolts, nuts, and screws organized as you remove them. This prevents small parts from being lost or misplaced, which can save time and frustration during reassembly. Additionally, a flashlight or work light can be invaluable for illuminating hard-to-see areas, ensuring you don’t miss any fasteners or clips.
If your Subaru Legacy GT has an engine cover with electrical connectors or sensors attached, a disconnect tool for electrical clips may be necessary. This tool allows you to safely release connectors without damaging the wiring harness. While not always required, it’s a good idea to have one on hand, especially if you’re unsure about the cover’s configuration.
Lastly, gloves and safety goggles are essential for personal protection. Gloves provide a better grip on tools and protect your hands from sharp edges or grease, while safety goggles shield your eyes from debris or accidental spills. With these tools and safety gear, you’ll be well-prepared to remove the plastic engine cover on your Subaru Legacy GT efficiently and safely.

Step-by-step removal process
Step 1: Prepare the Workspace and Gather Tools
Before beginning, park your Subaru Legacy GT on a flat surface, engage the parking brake, and allow the engine to cool completely to avoid burns. Gather the necessary tools, which typically include a ratchet or socket wrench, various socket sizes (commonly 10mm and 12mm), and a screwdriver. Some models may require a Torx bit, so check your engine bay for specific fasteners. Ensure you have a clean workspace and a tray or container to keep removed bolts and screws organized.
Step 2: Locate and Remove the Fasteners
Inspect the plastic engine cover to identify all securing points. Most Subaru Legacy GT models have a combination of bolts and clips holding the cover in place. Start by removing the bolts using the appropriate socket or wrench. Work systematically, beginning from one side and moving across to ensure even detachment. For clips, use a flathead screwdriver to gently pry them out without damaging the plastic. Be cautious not to overtighten or force any fasteners to avoid stripping threads or breaking clips.
Step 3: Detach Electrical Connectors (If Applicable)
Some engine covers may have integrated sensors or wiring harnesses. If your Subaru Legacy GT has these, locate any electrical connectors attached to the cover. Gently disconnect them by pressing the release tab and pulling the connector apart. Avoid pulling on the wires themselves to prevent damage. Label the connectors or take a photo for reassembly reference if needed.
Step 4: Lift and Remove the Engine Cover
Once all fasteners and connectors are removed, carefully lift the plastic engine cover straight upward. Be mindful of any tabs or grooves that may catch on surrounding components. If the cover feels stuck, double-check for any missed fasteners or clips. Slowly wiggle the cover side to side if necessary, but avoid excessive force to prevent cracking the plastic.
Step 5: Clean and Inspect the Cover
With the cover removed, take the opportunity to clean both the cover and the exposed engine bay. Use a mild degreaser and a soft brush to remove dirt and grime. Inspect the cover for cracks, warping, or damage that may require replacement. If the cover is in good condition, store it in a safe place until reinstallation. Ensure the engine bay is dry before proceeding with any maintenance or repairs.
Step 6: Reinstallation (Optional)
If you’re reinstalling the cover after maintenance, follow the removal steps in reverse. Align the cover carefully, ensuring all tabs and grooves fit properly. Reattach the fasteners hand-tight before using the wrench to secure them. Reconnect any electrical connectors and double-check that everything is seated correctly. Start the engine briefly to ensure no issues arise before closing the hood.

Reinstalling the engine cover properly
Reinstalling the engine cover on your Subaru Legacy GT requires attention to detail to ensure it fits securely and functions properly. Begin by aligning the cover with the engine bay, ensuring that all mounting points and tabs are correctly positioned. The cover should sit flush against the engine, with no gaps or misalignments. Take your time to inspect the cover’s edges and ensure it matches the contours of the engine bay perfectly. If the cover feels off or doesn’t align, double-check the orientation and adjust as needed.
Next, reinsert the fasteners or clips that secure the engine cover in place. Refer to the removal process to identify the exact locations of these fasteners. Start by hand-tightening each fastener to avoid cross-threading or damaging the plastic cover. Once all fasteners are in place, use the appropriate tool to tighten them securely, but avoid over-tightening, as this can crack the plastic. Ensure each fastener is snug and holds the cover firmly in position.
After securing the fasteners, verify that the engine cover is seated correctly and doesn’t move or rattle. Gently press along the edges and corners to confirm it’s stable and properly attached. Check that all tabs and clips are engaged and that there are no obstructions or interference with nearby components. A properly installed cover should feel solid and integrated with the engine bay.
Finally, start the engine and let it idle briefly to ensure the cover remains in place and doesn’t vibrate excessively. Listen for any unusual noises that might indicate a loose fastener or improper fit. If everything appears secure and functional, you’ve successfully reinstalled the engine cover. Regularly inspect the cover during routine maintenance to ensure it stays in good condition and continues to protect your engine components.

Common issues and solutions
Removing the plastic engine cover on a Subaru Legacy GT is a straightforward task, but it’s not uncommon to encounter a few issues along the way. One common issue is difficulty locating the fasteners or clips that secure the cover. The engine cover is typically held in place by a combination of screws, clips, and tabs. If you’re unsure where to start, refer to the vehicle’s manual or online resources specific to your model year. Solution: Begin by identifying all attachment points, which are often found along the edges of the cover and near the center.
