Questions and Answers
Which Toyota and Lexus models does 16331-31220 fit?

How can I verify that 16331-31220 is a genuine Toyota part?
Check three things: (1) the box label carries the ten-character Toyota number 16331-31220 together with the country-of-origin marking; (2) factory hoses are secured with constant-tension spring-band clamps (part families 96111-xxxxx, 90466-xxxxx, 16581-xxxxx), never screw-type worm-gear clamps; (3) 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 supply the commercial invoice, packing list and, on request, a Certificate of Origin for any shipment.
Where is 16331-31220 installed on the vehicle?
It is fitted in the Engine cooling system (radiator and water outlet) position.
How many pieces are needed for 16331-31220?
Supplied as one piece per position – check the quantity required for your application.
What documentation comes with an order?
Every shipment can include the commercial invoice and 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.
Is 16331-31220 the same part across different markets?
As a Lexus Genuine Parts number, 16331-31220 is the same across markets; where another catalog lists a different number for the same function, that number is the superseded one – confirm with our sales team before dispatch.
