A genuine Water Bypass Hose shows the Toyota number 16261-31100 on the box label with the country-of-origin marking. On the part itself, the pipe number is printed on the body and matches the packaging label, and fuel joints lock with a specific retaining clip rather than a hose clamp; and factory hoses are secured with constant-tension spring-band clamps (part families 96111-xxxxx, 90466-xxxxx, 16581-xxxxx), never screw-type worm-gear clamps. Documentation is available on request – commercial invoice, packing list and Certificate of Origin.

This part is listed for the Engine Cooling System (Radiator and Water Outlet) position.
How many pieces are needed for 16261-31100?
Sold as one piece per position – check the quantity required for your application.
Is the genuine part worth it compared with an aftermarket equivalent?
What the genuine item buys you is concrete: the number is confirmed against the official Toyota catalog, so the application is exactly right for your chassis; and the part is verified against the OE number before dispatch, so you receive exactly what your chassis requires.
What documentation comes with an order?
Each order can ship with the commercial invoice, the packing list and, on request, a Certificate of Origin; the part number is printed on the body or cast into the housing, so you can match it against the invoice.
