  • Thermostat failure — symptoms and diagnosis — Normal reference numbers. Thermostat should be marked to open the small (cabin/block) loop at 82°C (some batches 82–83°C) and reach full opening around 97–99°C, when the… (153 sources)
  • Air conditioning — refrigerant system and diagnosis — Refrigerant capacity. The X80's A/C system holds 500 g of refrigerant (freon). The refrigerant type/spec is printed on a nameplate sticker, reportedly on the radiator… (97 sources)
  • Thermostat — parts and replacement — Part numbers and alternatives. Factory FAW thermostat part number 1306010-37K fits the Besturn X80; seen for sale at kitzapchasti.ru and autocraft-kzn.ru for 1,490 RUB… (56 sources)
  • HVAC defrost airflow design — Air leaks to unintended directions regardless of mode: multiple owners report that the X80's HVAC deflector dampers seal poorly (worn gaskets/seals on the vent dampers),… (44 sources)
  • Coolant system — capacity and air-bleeding — Total capacity and drain behavior. FAW X80 coolant system total capacity is 7.5–7.7 liters (owner's manual specifies 7.5 L with G30-91 extended-service coolant,… (39 sources)
  • A/C condensate drainage — Dripping under the car is normal. Water dripping from underneath the vehicle while/after A/C use is expected condensate from the A/C evaporator, not a leak to worry… (37 sources)
  • Thermostat replacement and cooling-system bleeding — Symptoms of a failing thermostat: car doesn't warm up (temperature gauge stays near 2 divisions from zero), and it cools further at speed — a sign the thermostat is… (35 sources)
  • Radiator — Mazda cross-compatibility and parts — Mazda CX-5 coolant-radiator cross-compatibility (with modifications). A Mazda CX-5 (specific generation referenced in a linked photo) engine coolant radiator is… (33 sources)
  • Coolant specification — G12/G12+/G13/G30 — Baseline spec. The FAW Besturn X80 uses coolant type G12+ or G12++. G13 (a more modern formulation) can also be used as an alternative, but compatibility with whatever… (32 sources)
  • AKPP — ATF temperature management — Optimal transmission (ATF) temperature on the X80 is 92–95°C; a 105–110°C threshold is considered critical. The factory heat exchanger for the АКПП is undersized for… (30 sources)
  • Engine operating temperature and fan engagement — Baseline (no A/C). Normal FAW X80 engine operating temperature is 92–95°C. Auxiliary cooling fans engage at 98–99°C and pull the temperature back down. Under… (28 sources)
  • HVAC blend-door damper — failure modes — The X80's climate control uses several plastic-geared blend/direction doors (dampers) to mix hot/cold air and route it to face/feet/defrost vents, driven by small… (26 sources)
  • HVAC blower motor — failure and repair — Symptom pattern. The HVAC blower doesn't activate on a cold startup, but may kick in after the engine/cabin warms up, then runs with fluctuating power — pulsing on and… (25 sources)
  • HVAC controls — recirculation and mirror heating — Recirculation activates unintentionally when the windshield washer is used. Some X80 units automatically activate recirculation (рециркуляция) whenever the windshield… (24 sources)
  • Dashboard panel removal — A/C and heater access — To reach the evaporator core for A/C repair (leak fix, clog clearing, etc.), the dashboard must be substantially disassembled: (1) remove the hood-release lever by… (20 sources)
  • LPG/GBO installation — cooling-system effects — Multiple owners who installed an LPG/GBO gas-conversion system reported cooling-related overheating symptoms afterward. Two independent case threads are combined here… (18 sources)
  • Heater blower motor fan — no separate part — If the heater blower motor's fan blade ("крыльчатка мотора печки") cracks or breaks, it cannot be purchased separately — only the complete motor assembly is available as… (18 sources)
  • Burning-oil smell in winter climate mode — Symptom. A fresh burnt-motor-oil smell from under the hood appears specifically when the winter climate mode (snowflake icon) is activated on the dashboard. The smell is… (18 sources)
  • Radiator mounting vibration and leaks — Mounting vibration/rattle. A rattle or vibration felt when the engine is running is often caused by worn rubber mounting pads at the top of the radiator. Fix: install… (15 sources)
  • Cooling fan motor failure and parking sensor glitches — Root cause — cooling fans and parking sensors share wiring (2026-08 report). One owner brought the car in for a routine service task (blowing dust out of the fuse box)… (14 sources)
  • Water pump — brands and fitment — Dolz F-150 — recommended for quality and reliability. The Dolz F-150 water pump is recommended by the community for quality and reliability, available on OZON for… (12 sources)
  • Burnt-plastic smell from the heater — Symptom and candidate causes. A burnt-plastic smell while the heater is running, with a seasonal/wet-weather pattern, has been traced to a few different possible… (7 sources)
  • Heater hose and coolant-tube sourcing — Upper heater hose (heater-core inlet hose) — China-sourced supply option. The upper heater hose (upper "патрубок на печку") is a replaceable part, but no specific part… (7 sources)
  • Windshield air-intake water leak in rain — Root causes — windshield seal, cowl drainage, and intake-window suction, in combination. Heavy rain can cause water to enter the cabin through the driver-side air intake… (7 sources)
  • Radiator cleaning — debris and safe approach — Accumulation pattern. The radiator (and likely the A/C condenser mounted alongside it) accumulates a debris/dust "blanket" after roughly 2 years of operation, more… (6 sources)
  • Serpentine belt failure and coolant loss — What happens if the belt breaks while driving. The engine can briefly continue running on battery/alternator power alone if the serpentine belt breaks — electrically,… (6 sources)
  • Heater-core coolant leak into the cabin — Symptoms. A dripping sound from the passenger side, moisture found under the driver-side floor mat, and the heater ceasing to produce heat — together these point to… (5 sources)
  • Heater fan motor failure — diagnosis and repair — Symptom: heater fan motor stopped working in cold weather. (5 sources)
  • Water pump — price and failure modes — Failure occurs, frequency unclear. Community discussion confirms water pumps do fail over time on the X80, though no owner in this thread had hard statistics on failure… (4 sources)
  • Fan, A/C and water-pump relays and fuses (EWD) — Source: the factory electrical wiring diagram (EWD) pages shared as PDFs in the group. Values below are as printed on the diagrams; one rating is inconsistent on the… (2 sources)
  • Radiator flushing: no need for full removal — Flushing the radiator without fully removing it. To flush the radiator without taking it completely out of the car, remove the front bumper first — this gives enough… (2 sources)
  • Recirculation shutter motor failure — Mazda-donor fix — The recirculation-mode shutter motor's internal gears can break, causing a clicking sound whenever the shutter operates . The OEM replacement comes in the same housing… (2 sources)
  • Cooling trijunction replacement — Mazda 6 reference — The X80's cooling-system trijunction (three-way coolant hose connector) is reported to be the same part as used on the Mazda 6 (2G) GH, 2.0L, 2007 model, based on the… (1 sources)
