Changan coolant-batch recall: why the official remedy starts with cleaning and fresh coolant

If an older Changan runs hot, checking a 2015 coolant-batch recall alongside the pump and radiator may be useful before preparing a quotation. The official action specifies cleaning the cooling system and replacing the coolant. Distinguishing a fluid problem from a physical-component fault helps avoid ordering an assembly before the cause is known.

Correct fluid level does not establish correct fluid performance

The manufacturer notice states that a supplier production-batch issue left some vehicles with coolant of insufficient oxidation resistance. Cooling performance could decline, with elevated coolant temperature in extreme cases. [Batch defect][S05]

Confirming that coolant reaches the specified level does not alone exclude this performance issue. Topping up addresses quantity; it does not prove the affected fluid has been replaced as required. Equally, not every high-temperature condition can be attributed to this batch defect.

The remedy includes cleaning, not merely topping up

Changan requires cleaning the affected vehicles' cooling systems and replacing the coolant. [Corrective action][S05] This differs from adding a little fluid or replacing a hose.

Where service records exist, confirm whether cleaning and coolant replacement were performed and whether they correspond to this action. The notice provides no universal cleaning-agent formula, mixing ratio or basis for choosing coolant by colour. Similar colour does not establish the same specification.

The fluid action does not automatically require a pump or radiator

The defect concerns coolant batches. The notice does not require every listed vehicle to receive a new water pump, radiator or thermostat. Additional component damage needs vehicle inspection evidence.

Conversely, having completed the fluid replacement does not exclude later leaks or other cooling faults. Explain this fluid correction separately from any additional component findings, rather than describing the complete system simply as “already repaired”.

Four production-period groups in the China notice

The historical manufacturer notice takes effect from Mar 31, 2015 and covers 121003 vehicles. Each group count is not an individual count for every model within it. [Scope and groups][S05]

| Models | Production period | Group quantity |
| --- | --- | ---: |
| CS75, Raeton | 2015-01-03—2015-02-12 | 21538 vehicles |
| CS35, Eado, Zhishang XT, Alsvin V7 | 2014-12-09—2015-01-30 | 65686 vehicles |
| Benni mini, CX20 | 2014-12-01—2015-01-30 | 14334 vehicles |
| Chana Star 2, Chana Star 3 | 2014-12-05—2015-02-27 | 19445 vehicles |

Scope and verification

This article covers only the historical China action above. It does not extend to all versions of these model families, current PLUS models or overseas markets. Jun 28, 2016 on the manufacturer page is an archive creation date, not a new recall date.

The notice does not separately list specific model years, per-model quantities or VIN endpoints; no public data were available for these items. Production periods alone cannot confirm an individual vehicle's eligibility. No public data were available for coolant OE numbers, approved formulations, cleaning-agent specifications or interchangeability. [To be verified] Contact the authorised party in China about the recall remedy. For ordinary compatibility checks, use the VIN and local factory parts catalogue; perform coolant replacement according to the applicable factory information.

After identifying the cooling component or fluid requirement, use the parts enquiry page.
