Coolant Reservoir: application and selection
| Check | Required record |
|---|---|
| Assembly identification | Motor or battery coolant circuit, molded shape, hose branches and cap |
| Vehicle boundary | Original FWD ATTO 3; production date, original sales market and installed equipment. EVO RWD/AWD needs a separate application record. |
| Component evidence | Overall, label, connector and mounting views; measured dimensions where they distinguish the assembly. |
A similar translucent tank can have different internal passages or cap requirements. Do not interchange motor and battery circuit tanks by appearance.
Compare connected components
Before combining a Electric Coolant Pump, coolant reservoir and Coolant Control Valve, confirm that each belongs to the intended coolant circuit; similar fittings do not establish common routing.
For a combined order, use the Atto 3 Cooling & Heat-Pump Circuits guide. Resolve vehicle differences through original versus EVO identification before comparing references.
When the original number is unavailable
Send the old coolant reservoir label with the mounting and connection views needed for this assembly. Mark measurements that remain unconfirmed. The OE and VIN identification checklist explains how to organize missing identification.
Supply contents and packing
Define tank, cap, sensor and bracket contents separately. Protect narrow branches and prevent contamination inside the reservoir.
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 Atto 3 assembly matched to its own vehicle and component record.
