Application boundary
Engine code, accessory layout, air-conditioning equipment and production phase must be resolved before a proposed part is treated as relevant.
Corolla engine parts · procurement guide
Map the complete belt path and accessory package before selecting a tensioner by pulley diameter.

Quote definition
No universal OE number can safely cover this component family. A useful request combines vehicle, part, commercial and packing evidence that can be checked in writing.
Engine code, accessory layout, air-conditioning equipment and production phase must be resolved before a proposed part is treated as relevant.
Record pulley diameter and ribs, arm offset, mounting pattern, travel range and damping unit; connector or mounting similarity alone is not enough.
Write the request as complete automatic tensioner, pulley-only line, idler, belt or hardware package, with included hardware and seals stated separately.
Protect pulley grooves and bearings, restrain the spring arm and separate mounting hardware from finished surfaces.
OE evidence gate
Corolla applications for accessory belt tensioners divide by engine code, accessory layout, air-conditioning equipment and production phase. No single OE number is published without a reconciled vehicle and installed-part record.
VIN or chassis/model code, production month, complete powertrain or equipment branch, old-part number and all relevant views.
No current supersession, universal fitment, genuine/OEM supply, inventory, price or lead time is implied.
Decision record
| Decision point | Evidence to send |
|---|---|
| Vehicle branch | Record the Corolla generation, chassis/model code, production month, body style and destination market before comparing accessory belt tensioners. |
| System application | Confirm engine code, accessory layout, air-conditioning equipment and production phase; a sales name or nominal model year does not resolve this branch. |
| Physical interface | Compare pulley diameter and ribs, arm offset, mounting pattern, travel range and damping unit, using clear installed and removed-part photos wherever possible. |
| Requested assembly | State whether the line covers complete automatic tensioner, pulley-only line, idler, belt or hardware package; 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 | Protect pulley grooves and bearings, restrain the spring arm and separate mounting hardware from finished surfaces. |
Part-specific risk
For Corolla accessory belt tensioners, the controlling difference can be pulley diameter and ribs, arm offset, mounting pattern, travel range and damping unit. Keep every proposed part tied to the vehicle record and installed component; a broad year-range cross reference is not approval evidence.

Start with generation, chassis/model code and production month, then resolve engine code, accessory layout, air-conditioning equipment and production phase. That branch is more useful than model year alone.
Photograph the installed position, label and mounting or connector faces, then record pulley diameter and ribs, arm offset, mounting pattern, travel range and damping unit. Keep every measurement tied to the same removed component.
State complete automatic tensioner, pulley-only line, idler, belt or hardware package. List seals, brackets, motors, modules, hardware or paired sides separately so quotations can be compared on the same contents.
Protect pulley grooves and bearings, restrain the spring arm and separate mounting hardware from finished surfaces.
The research did not establish one safely scoped public reference for this broad component page. Send the old-part number, VIN or chassis/model code, production month and installed-part evidence instead.
