Expansion Tank for Toyota Land Cruiser: Carbon Steel
This expansion tank for the Toyota Land Cruiser is specified around carbon steel, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is warranty claims traced back to a single lot, or reorders that did not match the approved sample. Both are specification problems, and both are preventable.

Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.

Questions buyers ask
What is the minimum order quantity?
The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
