The oil filter location on a 2008 Highlander depends on the engine. The four‑cylinder model uses a traditional spin‑on filter on the front passenger side near the oil pan, while the V6 uses a cartridge‑style filter inside a round housing on the engine’s right side.
Two engines were offered in the 2008 Highlander: a 2.4-liter four‑cylinder (2AZ‑FE) and a 3.3-liter V6 (3MZ‑FE). Because the oil filtration system differs between these engines, locating and servicing the filter requires following the specific guidance for your model. The sections below describe each setup, along with access considerations and steps for replacement.
2.4-liter four‑cylinder Highlander (2AZ‑FE)
For the four‑cylinder version, use this guide to find the spin‑on oil filter on the engine block.
- Location: on the front side of the engine, toward the passenger side, just above the oil pan. The filter is a traditional canister type that you can see from the engine bay or from beneath the vehicle.
- Access: you may need to remove the front splash shield and possibly gain access from the passenger‑side wheel well to reach the filter and drain plug.
- Replacement steps: with the engine cool, place a drain pan beneath, loosen the filter counterclockwise with a filter wrench, let it drain, remove and replace with a new filter, reseal the gasket, reinstall the shield, and refill with the correct oil specification and quantity.
In short, the 2.4L Highlander keeps a straightforward spin‑on oil filter on the engine’s front passenger side, typically accessible from beneath or via the wheel well with basic hand tools.
3.3-liter V6 Highlander (3MZ‑FE)
For the V6 version, use this guide to locate the cartridge‑style oil filter housed in a round canister on the engine’s right side.
- Location: on the engine’s right side (closer to the firewall), inside a round filter housing rather than a traditional spin‑on canister.
- Access: you may need to remove a small cover, shield, or part of the intake tubing to reach the filter housing; a cap or socket tool is typically used to remove the housing cap.
- Replacement steps: open the housing cap, remove the used cartridge, install a new cartridge and O‑rings, reseal the housing, reassemble any shields or covers, and refill with the correct oil amount and grade.
In brief, the V6 Highlander uses a cartridge filter in a round housing on the engine’s right side, which is accessed differently than a spin‑on filter and may require removing a few covers for access.
Safety and verification tips
Always verify your exact engine code before servicing, since the filter type and access can vary by engine within the same model year. If in doubt, consult the owner's manual or a Toyota service publication for your VIN, and consider having a professional perform the change if you’re uncomfortable working around the engine bay.
How to confirm which engine your Highlander has
Check the vehicle identification number (VIN) or look at the engine code stamped on the engine block near the intake manifold or valve cover. The 2AZ‑FE and 3MZ‑FE engines have distinct codes, and the service procedure for the oil filter will follow that engine design.
Summary
For a 2008 Toyota Highlander, the oil filter location depends on the engine. The four‑cylinder 2AZ‑FE uses a conventional spin‑on filter on the front passenger side near the oil pan, accessible from beneath or the wheel well. The V6 3MZ‑FE uses a cartridge‑style filter inside a round housing on the engine’s right side, requiring removal of covers or shields for access. Verify the engine type from the VIN or manual to follow the correct procedure. Always use proper safety practices and consult the manual for exact oil specifications and capacity.
