Radiator — Mazda cross-compatibility and parts

Tags: #radiator · #mazda-6-compat · #part-number · #cross-reference

Mazda CX-5 coolant-radiator cross-compatibility (with modifications). A Mazda CX-5 (specific generation referenced in a linked photo) engine coolant radiator is compatible with the X80 with modifications. Automatic-transmission Mazda units have two transmission-fluid cooling ports that must be plugged when installing on a manual-transmission-configured X80, since the X80's manual-only radiators don't have transmission-fluid circuit connectors to match. Taiwan-sourced aftermarket radiators of this type cost approximately 6,300 RUB (May 2024, RU market). Radiator front panel/shroud part numbers: 5CA053110D (analog/aftermarket) and 5CA053110E02 (original, "02" suffix) — both variants are reported fully compatible with both facelift and pre-facelift model years despite the different part numbers, and the analog version (ordered first in this case) is functionally equivalent to the original.^{123456789101112131415}

Radiator steam-vent (siphon) hose — function and aftermarket gotcha. A small siphon/steam-vent hose on the radiator connects from the radiator-cap area to the cooling-jacket body near the temperature-sensor location. Its function is to prevent air-lock formation in the cooling system by letting trapped air escape. This hose was a specific source of confusion for owners installing aftermarket radiators that lack this feature/fitting — but it's essential to proper cooling-system operation, so its absence on a replacement radiator is worth flagging to a supplier rather than skipping.^161718192021

Mazda GH-series radiator cross-compatibility — cost advantage. The engine coolant radiator can also be replaced with a Mazda GH-series unit (exact year/displacement uncertain) at roughly 2.5× lower cost than the OEM FAW replacement. Key fitment requirement: verify attachment points (mounting pins and hose connections) against the replacement unit before purchase — this was successfully done by matching physical specs in one reported case, driven by prohibitive FAW OEM pricing.^2223242526

Mazda radiators (coolant + A/C condenser) — general 2× cost advantage. More broadly, Mazda radiators — both the A/C condenser and the engine coolant radiator — are reported as compatible alternatives for the X80, typically around 2× cheaper than OEM FAW parts. Important: verify pathing/tubing compatibility with a technician before installation, since connection points can differ between the two platforms even when the core fits.²⁷²⁸²⁹

OEM radiator part number and current pricing. OEM coolant radiator part number 5AA015200 (cross-referenced as FC2115200) fits both the FAW Besturn X80 and X80F, for 2.0L and 2.3L engines. Available from kitparts.ru at 14,126 RUB (February 2026, RU market); the supplier offers Telegram support and a phone line (+79689168092).³⁰ Владельцу из Москвы, которому радиатор был нужен в наличии, посоветовали обзвонить магазины и уточнить наличие.³¹ نُصح أحد ملّاك موسكو، وكان يحتاج هذا الرادياتير متوفرًا محليًا، بالاتصال هاتفيًا بالمتاجر للتأكد من توفره.³¹ A Moscow owner who needed this radiator in stock locally was advised to phone shops to check availability.³¹

Mazda 6 GG cross-reference — unverified. A Mazda 6 GG-generation radiator has been reported as a potential fit for the X80, but this is explicitly unverified. Recommendation before ordering: confirm ABS-sensor-bracket compatibility with the supplier, since that's the specific fitment risk flagged in this report.³²

Broader market context — X80/Mazda cross-platform pricing arbitrage. A general pricing pattern reported alongside the radiator cost comparisons above, illustrated with a non-radiator example: OEM brake-cylinder pricing (May 2026, RU market) was 5,000 RUB for the FAW X80 part versus 13,000 RUB for the equivalent Mazda part. Because many X80 components are sourced from the same Mazda platform lineage but priced lower under the FAW brand, this arbitrage extends beyond radiators — some buyers reportedly source the cheaper X80-branded part and resell it as the Mazda-branded equivalent to buyers in the higher-priced market. Useful context when evaluating any "X80 part is dramatically cheaper than the Mazda equivalent" claim on this card: it's a documented, recurring market pattern, not a one-off coincidence.³³
