How should hood struts be installed?
Replacing hood struts is typically a straightforward DIY task: remove the old gas springs, mount new ones to the same points on the hood and body, and test the hood to ensure smooth, safe operation. Following manufacturer instructions for your specific kit is essential, as some models use different mounting hardware or orientations.
What you’ll need
Before you begin, gather the tools and materials listed here so you can complete the installation without interruption. Using the right hardware and a helper makes the job safer and faster.
- New hood struts (gas springs) compatible with your vehicle
- Socket set and wrenches (sizes per your kit)
- Flat-head and Phillips screwdrivers
- Pliers or needle-nose pliers
- Torque wrench (if the kit specifies a torque value)
- Safety glasses and gloves
- Camera or notes to document the original orientation
- Support for the hood (a second person or a prop rod)
- Threadlocker or antiseize compound (if recommended by the kit)
Having these items on hand helps ensure a clean, safe replacement that aligns with the vehicle’s design. If your kit includes brackets or spacers, keep them ready and review their placement before starting.
Step-by-step installation
Follow these steps to remove the old struts and install the new ones, making sure to stay safe and organized throughout the process.
- Park the car on a flat surface, turn off the engine, and engage the parking brake. Open the hood and have a helper support it so it cannot fall.
- Identify and photograph the original struts and their mounting points. This helps ensure you replicate the correct orientation and fit with the new units.
- Remove the old hood struts. Depending on the design, you may need to pry off retaining clips with a small screwdriver or unbolt a mounting bracket. Be prepared for the struts to shift once released.
- Compare the old struts to the new ones. Check the length at closed and open positions, mounting ends, and any required brackets or spacers. Confirm you have the correct side for each strut (left and right) if the kit specifies.
- Install the mounting brackets or adapters on the body/frame side first, using the hardware provided. Tighten to the manufacturer’s recommended torque, if specified.
- Attach the upper mounting points to the hood or the hood hinge area, following the kit’s diagram or the photographed reference from step 2. Ensure the ball studs or pins align cleanly with the mounting holes.
- Secure the struts, starting with the lower end then the upper end. Do not force the mounts; if you encounter binding, recheck alignment and hole spacing.
- Install any clips or retainers that came with the kit to prevent the ends from coming loose during operation.
- With the hood supported, slowly lower and raise the hood to confirm smooth operation. If the hood doesn’t lift or settles abruptly, recheck alignment and fasteners.
- Test the hood through several cycles under normal operating conditions. Ensure the hood holds open at a comfortable height and closes without resistance or noise.
Executing these steps carefully helps ensure the new hood struts operate reliably and safely, matching the vehicle’s design and safe lifting requirements.
Safety tips and common issues
Hood strut installation involves lifting a live hood and dealing with pressurized components. Observe these safety precautions and address common problems proactively.
- Never work under a hood that is not securely supported. Always use a helper or a sturdy prop rod when the hood is raised.
- Keep hands, fingers, and clothing away from pinch points near the hinges and ball studs while attaching or adjusting.
- If you hear hissing, see leakage, or notice unusually slow or stiff operation, stop and inspect the seals, mounting points, and alignment. Damaged struts should be replaced rather than reused.
- Ensure both struts are compatible and installed in the correct positions on each side. Uneven mounting can cause uneven lifting and strain the hood or hinges.
- After installation, periodically check the mounting hardware for looseness and the integrity of the mounting brackets. Re-torque as needed per the kit’s instructions.
Common issues often stem from misalignment, loose fasteners, or installing the struts with the wrong orientation. If you’re unsure, consult the manufacturer’s installation guide or seek professional assistance to avoid damage to the hood or hinges.
Summary
Installing hood struts involves removing the old units, mounting the new ones at the correct points with proper hardware, and verifying smooth, safe operation through multiple lift cycles. Documentation of the original orientation helps ensure proper fit, and adherence to the kit’s instructions is key. When in doubt, a professional installation can prevent damage and ensure reliable hood support.
