Questions and Answers
Which Toyota or Lexus models and years does 16261-31040 cover?
16261-31040 fits LEXUS GS SERIES, LEXUS GS30/35/43/460, LEXUS GS460/430/350, LEXUS IS SERIES, LEXUS IS250/300 and LEXUS IS250/350, built from 2003 to 2014.
How can I verify that 16261-31040 is a genuine Toyota part?
To verify this Water Bypass Hose, look for the ten-character number 16261-31040 on the box label together with the country-of-origin marking, then check that the hose is moulded to the vehicle’s routing with pre-formed bends and connection diameters, and each position carries its own OE number, and that 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. We can provide the invoice, packing list and CoO for any order.
Where is 16261-31040 installed on the vehicle?
It is fitted in the Engine (Radiator and Water Outlet) position.
How many pieces are needed for 16261-31040?
You get one piece per position – check the quantity required for your application.
Is there anything I need to know before installing this part?
Worth knowing first: Let the system cool fully before opening it, and refill with the specified coolant.
Is the genuine part worth it compared with an aftermarket equivalent?
The genuine part differs in ways that show up in service: the part is verified against the OE number before dispatch, so you receive exactly what your chassis requires, and constant-tension spring clamps hold steady pressure as the hose expands and contracts, where screw clamps can loosen over time.
