Are Lincoln parts the same as Ford? Start with the pairs

Each pair shares a platform in the years given. Outside them, check the Lincoln on its own.

• Navigator and Expedition: the first Navigator (1998 to 2002) was based directly on the Expedition, launched a year earlier. The line continued as U228 (2003 to 2006), U326 (2007 to 2017), U554 (2018 to 2024) and U718 (from 2025).
• Aviator and Explorer: the first Aviator (2003 to 2005) was based on the third-generation Explorer. The second, from 2020, shares Ford’s CD6 platform with the sixth-generation Explorer.
• Corsair and Escape: the Corsair replaced the MKC in 2019 and shares its C2 underpinnings with the fourth-generation Escape.
• MKX and Nautilus with the Edge, MKZ with the Fusion: all on Ford’s CD4 platform, the MKX from 2015 to 2018 and the Nautilus from 2019 to 2023 next to the Edge, the MKZ from 2013 to 2020 next to the Fusion.

What Ford’s bulletins show crossing over

Ford writes many repairs once for both brands. Customer Satisfaction Program 18N01, from July 2018, covered early 2018 Expedition and Navigator trucks built at Kentucky Truck that could have contaminated R-1234yf refrigerant. One parts list served both: compressor JL1Z-19703-AB, condenser HL3Z-19712-A and the lines, valve and evaporator cases around them.

Where that list splits, wheelbase decides it, not the badge. The rear evaporator line is JL1Z-19867-CA on a short-wheelbase truck and JL1Z-19867-DA on a long one, whichever brand it wears. The exhaust is another story: the program gives the Expedition and the Navigator separate tailpipe and muffler removal steps.

The labor did not match. Ford allowed 12.9 hours on a two-wheel-drive Expedition and 14.2 on a two-wheel-drive Navigator, which is worth knowing before you quote a Lincoln at the Ford price.

Bulletin 22-2433, from December 2022, fixes a slow fuel fill on the 2020 to 2022 Escape, Corsair, Explorer and Aviator and the 2021 to 2022 Bronco Sport. One filler pipe, LX6Z-9034-JE, fits the Bronco Sport, Escape and Corsair with the 1.5, 2.0 and 2.3 engines. The driveshaft flexible coupling, L1MZ-4782-A, is listed for every Explorer and Aviator.

The plug-in hybrids pair up as well. LX6Z-9034-JD serves the 2.5 PHEV in both the Escape and the Corsair. The Escape’s regular hybrid takes a pipe of its own, LX6Z-9034-JC, and the Corsair is not offered with that powertrain.

Where Lincoln gets its own number

The same bulletin shows the limits. The Explorer’s filler pipe is L1MZ-9034-AJ, while the Aviator takes L1MZ-9034-X with the 3.0 EcoBoost and L1MZ-9034-AC as a hybrid. The capless filler housing changes too: LB5Z-7827936-A on a non-hybrid Explorer without a locking filler, LC5Z-7827936-A on an Aviator 3.0 EcoBoost.

Beyond the bulletins, expect body panels, lamps, grilles and interior trim to be Lincoln parts. Treat modules the same way until the catalog shows a shared number.

Reading a Ford part number on a Lincoln

Lincoln uses Ford’s numbering, so a shared part has one number. A service number such as L1MZ-9034-AJ has a four-character prefix, a basic number for the kind of part and a suffix. Every fuel tank filler pipe in bulletin 22-2433 has the basic number 9034. The prefix differs between the Escape family (LX6Z) and the Explorer family (L1MZ), and the suffix picks the version.

A shared basic number tells you two parts do the same job, not that they swap. Match the whole number, and let the catalog tell you when a newer suffix supersedes an older one.

How to check a Lincoln part against a Ford by VIN

Run the Lincoln VIN in the Lincoln catalog and the Ford VIN in the Ford catalog. Both open Ford’s Microcat on VINsearch, so the two builds sit behind one login. Open the same diagram on each and compare the full numbers.

If you only have a part in your hand, check the number’s format with the free OEM number lookup before you search it in the catalog.
