Application boundary
Refrigerant, evaporator connection and valve block design must be resolved before a proposed part is treated as relevant.

Toyota Corolla Expansion Valves
Match refrigerant and evaporator connection first, then record valve-block port spacing, bolt pattern, control type and seal requirements.

Quote definition
Define the expansion valves 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 port spacing, bolt pattern, sensor bulb/control type and seals; connector or mounting similarity alone is not enough.
Assembly scope
Write the request as valve block, O-ring set or pipe joint as separate lines, with included hardware and seals stated separately.
Transit control
Cap every port and keep small seals labeled to the exact valve line.
OE evidence gate
VIN and installed-part evidence required
No safely scoped public reference was established for this broad page during the 2 August 2026 review. Publishing an unverified number would create more fitment risk than it removes.
Evidence statusResearch required before quotation
What to submit
VIN or chassis/model code, production month, complete powertrain or equipment branch, old-part number and all relevant views.
What is not claimed
No current supersession, universal fitment, genuine/OEM supply, inventory, price or lead time is implied.
Decision record
Six checks for a quote-ready expansion valves line
| Decision point | Evidence to send |
|---|---|
| Vehicle branch | Record the Corolla generation, chassis/model code, production month, body style and destination market before comparing expansion valves. |
| System application | Confirm refrigerant, evaporator connection and valve block design; a sales name or nominal model year does not resolve this branch. |
| Physical interface | Compare port spacing, bolt pattern, sensor bulb/control type and seals, using clear installed and removed-part photos wherever possible. |
| Requested assembly | State whether the line covers valve block, O-ring set or pipe joint as separate lines; 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 port and keep small seals labeled to the exact valve line. |
Part-specific risk
Port spacing and refrigerant specification control the valve
For Corolla expansion valves, the controlling difference can be port spacing, bolt pattern, sensor bulb/control type and seals. Keep every proposed part tied to the vehicle record and installed component; a broad year-range cross reference is not approval evidence.

Corolla expansion valves questions
Which vehicle details separate Corolla expansion valves applications?
Start with generation, chassis/model code and production month, then resolve refrigerant, evaporator connection and valve block design. That branch is more useful than model year alone.
What physical evidence is useful for expansion valves?
Photograph the installed position, label and mounting or connector faces, then record port spacing, bolt pattern, sensor bulb/control type and seals. Keep every measurement tied to the same removed component.
How should the expansion valves assembly scope be written?
State valve block, O-ring set or pipe joint as separate lines. List seals, brackets, motors, modules, hardware or paired sides separately so quotations can be compared on the same contents.
What packing point matters for expansion valves?
Cap every port and keep small seals labeled to the exact valve line.
Why is no OE number shown for this expansion valves page?
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.
