2007-2014 Lincoln Navigator Hood: Diagnosing Corrosion and Latch Problems
This guide covers the common aluminum corrosion issue, latch failures, and how to inspect a used hood for your 2007-2014 Lincoln Navigator.
- The primary known issue is aluminum corrosion causing paint to bubble and peel, addressed by Ford TSBs 20-2233 and 19-2026.
- When buying a used hood, the most important check is for signs of corrosion on the underside seams.
- Latch problems are common and can often be fixed by thoroughly cleaning and lubricating the mechanism before replacing it.
- The total cost of replacement is driven by painting, which can cost significantly more than the hood panel itself.
Known Issues for 2007-2014 Lincoln Navigator Hoods
The most significant and widely documented issue for this generation of Lincoln Navigator is corrosion on the aluminum hood. This is not typical rust like you would see on a steel panel. Instead, it appears as bubbling or blistering paint, often accompanied by a white, powdery dust underneath. This problem is so common that Ford issued multiple Technical Service Bulletins (TSBs) for dealers, including TSB 20-2233 and 19-2026.
According to the bulletins, the corrosion is caused by iron particles that contaminated the aluminum during the manufacturing process. The corrosion often starts along the seams on the underside of the hood, where moisture can get trapped, and then creeps to the visible surface. While it is a serious cosmetic issue that can harm resale value, the corrosion on these aluminum panels does not typically lead to perforation (holes) like steel rust does. The official recommendation from Ford to fix this condition is complete panel replacement.
Hood Latch and Release Problems
Another common set of problems involves the hood latching mechanism. These issues are typically mechanical and not related to the aluminum corrosion problem.
- Hood Won't Open: The release lever inside the cabin may feel loose, or pulling it does nothing. This often points to a stretched or broken hood release cable.
- Hood is Stuck Shut: Sometimes the latch is simply stuck due to dirt and grime. After pulling the interior release, you may need to press down or pull up firmly on the hood to get it to pop. If the cable is broken, a mechanic may need to use a tool through the grille to manually trigger the latch.
- Hood Won't Close or Latch: If the hood won't stay shut, the interior release lever might be stuck in the open position. More commonly, the latch mechanism itself is dirty and needs to be cleaned and lubricated with white lithium grease.
Pro Tip: Before replacing a latch that isn't working correctly, thoroughly clean the mechanism with a degreaser and then apply a quality lubricant. In many cases, this simple maintenance can restore proper function without needing to buy a new part.
Symptoms of a Damaged or Failing Hood
Diagnosing a bad hood is usually straightforward and based on visual or physical signs.
- Visible Paint Bubbling: The clearest sign of the aluminum corrosion issue is paint blistering, typically starting on the front edge or seams.
- Dents, Dings, and Creases: Physical damage from impacts, hail, or falling objects compromises the hood's appearance and can lead to paint failure.
- Poor Alignment and Uneven Gaps: If the gaps between the hood and fenders are uneven, it could indicate past accident damage or worn hinge bushings.
- Vibration at Speed: A hood that vibrates or flutters while driving may have a failing latch or be misaligned.
- Hood Pops Open: If the hood pops from the primary latch to the secondary safety catch while driving, the latch mechanism is failing and is a critical safety issue.
Buying a Used Hood: What to Inspect
A used OEM hood is an excellent alternative to a new, expensive dealer part, especially since new aftermarket options are not widely available. A used hood from a dry, southern climate is less likely to have corrosion issues. Here’s what to check before you buy:
- Check for Corrosion: This is the #1 priority. Flip the hood over and meticulously inspect the seams where the outer skin is folded over the inner frame. Look for any sign of paint bubbling or white, powdery residue. If corrosion has started, it will continue to spread.
- Look for Signs of Previous Repair: Check for any areas that look wavy or feel different. Look at the underside for signs of body filler (often appearing as sanding marks or a different texture). A small magnet can help detect thick areas of filler on steel hoods, but it won't work on the Navigator's aluminum hood.
- Inspect for Damage: Run your hand over the entire surface to feel for small dents or dings that are hard to see. Check all edges and corners for bends or creases from a minor impact.
- Verify Straightness: Lay the hood on a flat surface to ensure it hasn't been twisted or bent. A twisted hood will never align correctly with the fenders.
- Check Included Hardware: See if the hood comes with the under-hood insulation liner, hinges, and latch striker. Getting these included can save you time and money.
Cost Comparison for a 2007-2014 Navigator Hood
The cost to replace a hood involves the part itself, plus the significant expense of painting and blending the color to match the rest of the vehicle.
| Part/Service | Estimated Cost | Notes |
|---|---|---|
| New OEM Hood | $500 - $1,500 | Price varies significantly by dealership. This is for an unpainted panel. |
| New Aftermarket Hood | $250 - $500 | General estimate, as direct-fit aftermarket aluminum hoods for this model are not common. Fitment may not be as precise as OEM. |
| Used OEM Hood | $200 - $750 | Price depends on condition and location. A color-matched hood in perfect condition is a great value. |
| Shop Labor (Installation) | $150 - $300 | Physical installation takes 1-2 hours. Alignment is key. |
| Shop Labor (Painting) | $400 - $1,000+ | Includes prep, paint, clear coat, and blending into adjacent panels for a perfect match. This is often the largest part of the total cost. |
Frequently Asked Questions (FAQ)
Is the 2007-2014 Lincoln Navigator hood made of steel or aluminum?
The hood on this generation of Lincoln Navigator is made of aluminum. This makes it lighter than a steel hood but also susceptible to a specific type of corrosion that causes paint to bubble.
Can I just repair the bubbling paint on my hood?
While you can sand down the corroded area and repaint it, this is often a temporary fix. The corrosion tends to start in the panel seams where it's difficult to treat properly, and it often returns. For a permanent solution, Ford's TSBs recommend replacing the entire hood panel.
How difficult is it to replace the hood myself?
Physically swapping the hood is relatively easy and requires basic hand tools (like a 10mm or 11mm ratchet) and a helper to lift the heavy panel. The difficulty rating is low (1 out of 5) for the unbolt/bolt-on process. However, the challenge is in the paint. Achieving a professional, color-matched finish is very difficult for a DIYer, making a full replacement (including paint) a 4 out of 5 in difficulty.
My hood won't pop open when I pull the lever. What's wrong?
The most likely causes are a stretched or broken release cable, or a latch mechanism that is jammed with dirt. Try having a helper push down and pull up on the hood while you pull the release lever. If that doesn't work, the cable may have snapped, requiring manual release of the latch through the grille.
