A RAV4 described as a “2011 model” is not enough to identify the reservoir covered here. The selected ACA33/ACA38 2.4L petrol application ends at 07/2011. Builds from 08/2011 fall outside that product’s stated catalogue scope and need a separate check.
This is a build-month question, not a reason to choose the nearest-looking bottle. A broad advertisement that spans several model years should not override the more specific application information.
Build month is more useful than registration year
Record the vehicle’s build month and VIN, together with the model and engine codes. The linked example is for ACA33/ACA38 with the 2.4L 2AZ-FE petrol engine, within 11/2005–07/2011. An initial registration date or a seller’s rounded year range does not supply all of that information.
For example, a vehicle recorded as built in 08/2011 is outside this example even though its registration year may still be 2011. That tells you to investigate another catalogue entry; it does not identify the later replacement or prove interchangeability with this tank.
Check the original reference and the mounting tabs
The ACA33/ACA38 reservoir product page records references 16470-0H100 and 16470-28110 for its stated scope. Match the original reference, tank shape, mounting tabs, filler neck and hose connection together.
Compare both tanks from the same direction. A changed camera angle can hide a tab or make the filler neck appear to sit differently. Similar plastic colour and a similar cap are weaker evidence than an agreed reference and mounting layout.
A cap-included package still has limits
The selected replacement is supplied with a cap. The hose and mounting hardware are not included. If the original hose, fasteners or another item also needs attention, have the installer confirm those requirements separately.
Do not infer a coolant capacity or cap specification from the bottle photograph. Use the vehicle’s own service information for the cooling-system requirements after the correct replacement has been identified.
What to send when the vehicle is near the cutoff
Send the VIN, full build month, ACA33/ACA38 code, 2AZ-FE engine details and a readable original reference. Add photographs of the tank, filler neck, tabs and hose connection where safely accessible. Mention a previous tank replacement if the fitted part may not be original.
The purpose is to resolve a boundary case before ordering. If the build date or original configuration disagrees with the linked product, pause that selection and obtain a vehicle-specific catalogue check. A reservoir match also does not diagnose a coolant-loss complaint; the workshop should establish the repair scope independently.
