Toyota Corolla Radiators
Confirm core size, hose locations, transmission-cooler ports and fan mounting before comparing radiator quotations.

Quote definition
Define the radiators 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 core size, inlet/outlet position, cooler ports and fan mounts; connector or mounting similarity alone is not enough.
Assembly scope
Write the request as radiator only or assembly with cap, drain and brackets, with included hardware and seals stated separately.
Transit control
Use corner protection and vertical-carton controls for fragile cores.
Scoped OE evidence
Public reference example: 16410-0T040
Radiator assembly. Public catalog evidence lists this radiator for selected 2009–2013 Corolla 1.8L and 2.4L applications.

Application boundary
Public catalog evidence lists this radiator 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 radiators line
| Decision point | Evidence to send |
|---|---|
| Vehicle branch | Record the Corolla generation, chassis/model code, production month, body style and destination market before comparing radiators. |
| System application | Confirm engine, transmission cooler and tank layout; a sales name or nominal model year does not resolve this branch. |
| Physical interface | Compare core size, inlet/outlet position, cooler ports and fan mounts, using clear installed and removed-part photos wherever possible. |
| Requested assembly | State whether the line covers radiator only or assembly with cap, drain and brackets; 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 | Use corner protection and vertical-carton controls for fragile cores. |
Part-specific risk
Cooling and transmission branches change the radiator tank layout
For Corolla radiators, the controlling difference can be core size, inlet/outlet position, cooler ports and fan mounts. Keep every proposed part tied to the vehicle record and installed component; a broad year-range cross reference is not approval evidence.

Corolla radiators questions
Which vehicle details separate Corolla radiators applications?
Start with generation, chassis/model code and production month, then resolve engine, transmission cooler and tank layout. That branch is more useful than model year alone.
What physical evidence is useful for radiators?
Photograph the installed position, label and mounting or connector faces, then record core size, inlet/outlet position, cooler ports and fan mounts. Keep every measurement tied to the same removed component.
How should the radiators assembly scope be written?
State radiator only or assembly with cap, drain and brackets. List seals, brackets, motors, modules, hardware or paired sides separately so quotations can be compared on the same contents.
What packing point matters for radiators?
Use corner protection and vertical-carton controls for fragile cores.
Does 16410-0T040 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.
