Cross-brand alternatives — Mazda 6 GG mounts. FAW X80 engine mounts can be replaced with Mazda 6 GG (Mazda6 GG) equivalent parts; multiple owners report success with this swap, sourced via Autodoc and other suppliers. Hydraulic versions are preferable to rubber-metal for durability and vibration isolation. Reported pricing (RU market, Jan 2025) is inconsistent across posts in this thread: one figure cites roughly 50,000 RUB paid for a hydraulic Mazda mount, alongside other mentions of ~3,600 RUB (a year prior) and 5,500+ RUB for newer hydraulic options — treat the exact price as unresolved and check current listings^{123456789101112131415161718}.

Right upper mount — part number 5CA139060. The right upper engine mount (правая верхняя подушка двигателя), OEM rubber type, has part number 5CA139060. A higher-quality alternative is the Mazda 6 GG hydraulic mount (higher cost, better damping). Both available at ooove.ru and kitzapchasti.ru¹⁹²⁰²¹.

Left-side mount — MT vs AT part numbers. The left-side engine mount part number differs by transmission type: manual (MT): 5ca039070; automatic (AT): 5ca139070. Mazda catalog research suggests these are interchangeable, though the functional difference (if any) between the two part numbers wasn't fully clarified in-thread; the manual-transmission version is not readily available in parts catalogs²².

Right mount — Mazda 6 GH compatibility (unconfirmed). Separately, the right engine mount's hydro-dampener may be compatible/swappable with Mazda 6 GH parts, which would save roughly 2,300 RUB (RU market, Apr 2025) versus the FAW-branded part; there was also discussion of using only the hydraulic cartridge insert from a non-OEM supplier (Juiki brand) if a full assembly isn't available^{2324252627282930}.

Conflict — GH interchangeability not fully verified. Full Mazda 6 GH interchangeability for the right mount is not confirmed: one owner (Сергей Куликов) reports an aftermarket rubber mount that lasted 4–6 years, but whether the GH hydro-dampener genuinely bolts on/functions as a drop-in was not settled in the thread.

Broader Mazda 6 parts cross-compatibility (same right-mount discussion thread). In the same conversation as the Mazda 6 GH right-mount discussion above, members reported wider FAW/Mazda 6 parts overlap: a coolant tee flange (фланец-тройник) matches 1:1 between FAW and Mazda across all measured parameters³¹³², and rear wheel-bearing seal blocks (сальники/уплотнения ступицы) were separately discussed as sourceable from Mazda, alongside general engine-mount rubber options — one owner planned to run a Patron mount short-term before eventually fitting an OEM part, noting that mismatched mount height or mount-bracket/stud geometry can force extra fitting work if the wrong part is chosen^24252633.

Right engine mount — OEM/Mazda part numbers and brand options, restated. FAW OEM right engine mount part number: 5CA139060. Cross-compatible Mazda 6 GG (Generation II) equivalent: GJ6A39060 — community reports confirm this Mazda mount is a direct bolt-in ("болт в болт"). Also compatible per a separate report: Mazda 6 Atenza (2002-present), sold as SAT ST-GJ6G-39-060E (same OEM number GJ6A39060) — a drop-in that reduces engine vibration and improves overall drivetrain smoothness, installed as easily as the factory mount. Aftermarket brand options: SAT (budget, verified fitment), JIKIU (premium, 10,000+ RUB), and genuine Mazda OEM (cheaper than JIKIU). Newer mounts are sold as hydraulic units, but their quality is questioned by some owners, who prefer the older mechanical-style mounts^{34353637383940414243444546}.

Right mount — FAW B50 cross-fit for cost savings. Right engine mounts (motor-mount supports) for the FAW X80 are reported identical in form and function to FAW B50 mounts. While the physical part is the same, B50 catalog pricing can be significantly lower — check both X80 and B50 catalogs when sourcing⁴⁷⁴⁸⁴⁹.

Cross-brand alternative — Mazda 6 GG (restated). First-generation Mazda 6 (GG) engine mounts can fit the FAW X80, giving an additional sourcing option when FAW-specific mounts are unavailable or overpriced⁵⁰.

Engine/transmission mount bracket ("гитара") — Mazda source and inspection note. The X80's engine/transmission mount bracket assembly, nicknamed "гитара" (guitar) for its shape, is sourced from Mazda. When sourcing replacements, check the rubber/elastomer condition — it can degrade on high-mileage cars — and confirm the correct variant if multiple engine configurations exist⁵¹⁵².

Engine mount specifications — hydraulic right mount and rear mount, alternate part numbers. Suspension-bushing engine mounts: right mount (hydraulic) identified as Tzer Li TZ-GJ6A-39-060; rear mount identified as Metaco 4710-009. The exist.ru catalog was cited as a useful source for detailed compatibility checking of these parts⁵³⁵⁴.

Right (front) mount — FAW B50 identical part, and a hydraulic-vs-air-filled dispute. The right (front) engine mount is hydraulic. The FAW B50 equivalent uses the identical OEM number FA0139060 on both models, but costs less on the B50 catalog (roughly 1,890 RUB) than on the X80 catalog (2,000+ RUB, RU market, Feb 2026) — consistent with the B50-cross-shopping pattern already documented on this card; B50 catalogs are recommended for cross-checking prices on many interchangeable parts. Conflict: one user claims the right mount is actually air-filled, not hydraulic ("воздушная камера"), contradicted by another owner (Victor) who states the factory mount is hydraulic and that the Patron-brand replacement is also hydraulic^{55565758596061}.

Left mount (over transmission) — X80-unique, OEM only, no Mazda cross-fit. The left mount is confirmed unique to the X80 and does not cross-fit with Mazda parts (unlike the right mount's Mazda/B50 compatibility already documented on this card). Options: source OEM only, or replace the individual silentblock (rubber bushing insert) with an aftermarket brand such as Жуки or Febest rather than the whole assembly. Mount-to-body installation points differ from the other mounts, so cross-shopping generic listings is riskier here^62636465.

Left mount — MT vs. AT differ, sourcing difficulty, and cross-brand alternatives. The left engine mount is different between manual (MT) and automatic (AT) transmission variants — the AT version is reinforced. The MT-specific mount is difficult to source. A practical alternative for a worn MT mount: re-press the silencer/rubber ring onto the original mount body rather than replacing the whole unit. Possible cross-brand alternatives: a Mazda 6 (GG, 2002) mount, or SAT ST-GJ6G-39-060E (Mazda 6 Atenza) — both already cross-referenced elsewhere on this card for the right mount, suggesting the same Mazda 6 parts family covers multiple mount positions^6667686970.

Rear engine mount — cold-idle vibration diagnosed and fixed with a Mazda 6 cross-fit part. A separate, detailed case: vibration transmitted to the chassis specifically at cold idle led one owner (Arсhi 77) to diagnose the rear engine mount (задняя опора двигателя) as worn/damaged. He sourced a MAZDA 6 02-07 AR00055 mount (MILES brand) as a confirmed compatible fitment, replacing it and resolving the vibration. General guidance from the thread: poor-quality aftermarket mounts degrade faster than OEM or better-quality replacements — worth paying for a known-good brand rather than the cheapest option^717273747576.

Mount alternatives and pricing — Mazda 6GG cross-fit for all three positions. Beyond the rear-mount cross-fit already documented on this card, Mazda 6GG mounts are reported compatible as replacements across the mount set. The left and right upper mounts rarely need replacement below 160,000 km (they can still look new at that mileage), while the center lower mount is identified as contributing significantly to cabin vibration when worn. Cost estimate for Mazda-sourced alternatives: roughly 2,000 RUB per mount (RU market, Mar 2024). Replacing the full set (left, right, and center-lower) is reported to substantially reduce overall engine vibration felt in the cabin^7778798081.
