Toyota Corolla Coolant Reservoirs
Identify tank-only or complete-tank scope, then match the filler neck, cap, level sensor, hose ports and mounting tabs.

Quote definition
Define the coolant reservoirs before comparing supply options
This page does not publish a universal OE number. It converts the buyer task into vehicle, part, commercial and packing evidence that can be checked in writing.
Interface evidence
Record mounting tabs, sensor provision, neck, hose ports and level marks; connector or mounting similarity alone is not enough.
Assembly scope
Write the request as tank only or tank with cap, sensor and hoses, with included hardware and seals stated separately.
Transit control
Support molded necks and tabs and keep caps bagged by application.
Scoped OE evidence
Public reference example: 16470-0T040
Radiator reserve tank assembly. Public catalog evidence lists this reservoir for selected 2009–2013 Corolla 1.8L and 2.4L applications.

Application boundary
Public catalog evidence lists this reservoir for selected 2009–2013 Corolla 1.8L and 2.4L applications. This is an identification lead, not universal Corolla fitment.
Source and limitation
Review the public catalog record (accessed 2 August 2026). POPXA does not claim stock, genuine supply, every-market fitment or a complete supersession chain.
Decision record
Six checks for a quote-ready coolant reservoirs line
| Decision point | Evidence to send |
|---|---|
| Vehicle branch | Record the Corolla generation, chassis/model code, production month, body style and destination market before comparing coolant reservoirs. |
| System application | Confirm bottle shape, cap system and hose routing; a sales name or nominal model year does not resolve this branch. |
| Physical interface | Compare mounting tabs, sensor provision, neck, hose ports and level marks, using clear installed and removed-part photos wherever possible. |
| Requested assembly | State whether the line covers tank only or tank with cap, sensor and hoses; reconcile every supplier photo with a written contents list. |
| Commercial basis | Give quantity per SKU, trial or repeat demand, destination port, preferred Incoterm and any inspection-document requirement. |
| Packing control | Support molded necks and tabs and keep caps bagged by application. |
Part-specific risk
Tank neck, cap pressure system and mounting tabs change together
For Corolla coolant reservoirs, the controlling difference can be mounting tabs, sensor provision, neck, hose ports and level marks. Keep every proposed part tied to the vehicle record and installed component; a broad year-range cross reference is not approval evidence.

Corolla coolant reservoirs questions
Which vehicle details separate Corolla coolant reservoirs applications?
Start with generation, chassis/model code and production month, then resolve bottle shape, cap system and hose routing. That branch is more useful than model year alone.
What physical evidence is useful for coolant reservoirs?
Photograph the installed position, label and mounting or connector faces, then record mounting tabs, sensor provision, neck, hose ports and level marks. Keep every measurement tied to the same removed component.
How should the coolant reservoirs assembly scope be written?
State tank only or tank with cap, sensor and hoses. List seals, brackets, motors, modules, hardware or paired sides separately so quotations can be compared on the same contents.
What packing point matters for coolant reservoirs?
Support molded necks and tabs and keep caps bagged by application.
Does 16470-0T040 fit every Toyota Corolla?
No. It is a scoped public catalog example. Confirm the VIN or chassis/model code, production date and installed component before quotation.
