Toyota Corolla Water Pumps
Start with the complete engine code and decide whether the request covers the pump, housing, pulley and gasket as separate or combined lines.

Quote definition
Define the water pumps 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 drive type, housing face, connector or pulley and pipe ports; connector or mounting similarity alone is not enough.
Assembly scope
Write the request as pump only, housing assembly or pump with gasket, with included hardware and seals stated separately.
Transit control
Cap every coolant port and protect machined sealing faces.
Scoped OE evidence
Public reference example: 16100-39466
Engine water pump assembly. Public catalog evidence lists this pump for selected 2009–2019 Corolla 1.8L and 2.4L applications.

Application boundary
Public catalog evidence lists this pump for selected 2009–2019 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 water pumps line
| Decision point | Evidence to send |
|---|---|
| Vehicle branch | Record the Corolla generation, chassis/model code, production month, body style and destination market before comparing water pumps. |
| System application | Confirm engine code and mechanical/electric pump design; a sales name or nominal model year does not resolve this branch. |
| Physical interface | Compare drive type, housing face, connector or pulley and pipe ports, using clear installed and removed-part photos wherever possible. |
| Requested assembly | State whether the line covers pump only, housing assembly or pump with gasket; 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 | Cap every coolant port and protect machined sealing faces. |
Part-specific risk
Pump housing and drive design follow the exact engine
For Corolla water pumps, the controlling difference can be drive type, housing face, connector or pulley and pipe ports. Keep every proposed part tied to the vehicle record and installed component; a broad year-range cross reference is not approval evidence.

Corolla water pumps questions
Which vehicle details separate Corolla water pumps applications?
Start with generation, chassis/model code and production month, then resolve engine code and mechanical/electric pump design. That branch is more useful than model year alone.
What physical evidence is useful for water pumps?
Photograph the installed position, label and mounting or connector faces, then record drive type, housing face, connector or pulley and pipe ports. Keep every measurement tied to the same removed component.
How should the water pumps assembly scope be written?
State pump only, housing assembly or pump with gasket. List seals, brackets, motors, modules, hardware or paired sides separately so quotations can be compared on the same contents.
What packing point matters for water pumps?
Cap every coolant port and protect machined sealing faces.
Does 16100-39466 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.
