Dolphin hatchback replacement parts
BYD Dolphin Coolant Reservoir Wholesale
Match the Dolphin coolant expansion tank to its installed location, hose branches and cap specification. Compare mounting tabs and visible level markings.

Coolant Reservoir: application and selection
| Check | Required record |
|---|---|
| Assembly identification | Reservoir location, hose branches, level markings and cap rating |
| Vehicle boundary | Dolphin hatchback; production date, original sales market and installed equipment. Identify torsion-beam or multi-link rear suspension; exclude Dolphin Mini, Surf and Seagull. |
| Component evidence | Overall, label, connector and mounting views; measured dimensions where they distinguish the assembly. |
A translucent tank outline is not enough if hose routing or pressure requirements differ. Keep it separate from the windscreen washer bottle.
Compare connected components
Trace the Electric Coolant Pump, coolant reservoir and Coolant Control Valve through the installed circuit before relating them to the Motor Cooling Radiator; a similar hose size does not establish the same circuit function.
For a combined order, use the Dolphin Cooling & Cabin Climate Components guide. Resolve vehicle differences through model, market and rear-suspension identification before comparing references.
OE / catalog identification example
| Reference | Limited application |
|---|---|
| 12598290-00 | Auxiliary coolant tank I; confirm hose layout and cap contents. Listed for Dolphin by an independent parts catalog; exact build and market remain subject to verification. |
Confirm the full installed reference, suffix and vehicle record before approval. The component illustration does not establish the identity or fitment of the numbered item.
Supply contents and packing
State bare tank or tank-with-cap contents and any level-sensor provision. Protect necks and branches from carton loading.
State quantities, destination and sample requirements. Agree inspection points with the quality-control checklist before approving a bulk order.
Other vehicle applications
For a mixed-model list, compare other radiator and cooling applications. Keep each Dolphin assembly matched to its own vehicle and component record.
