Buying Engine Parts for a 2025 Toyota 4RUNNER
On this vehicle, the engine covers the internals and hard parts that build compression and keep oil where it belongs — gaskets, bearings, camshafts, lifters, seals and timing components.
- You do not need to pick an engine: every engine part on this page fits both the 2.4L L4 ELECTRIC/GAS Turbocharged and the 2.4L L4 Turbocharged.
- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
- Cross-reference the manufacturer part number against your old part or a service-manual listing.

Our catalog currently lists 55 engine parts for the 2025 Toyota 4RUNNER across 11 subcategories and 22 brands, covering both the 2.4L L4 ELECTRIC/GAS Turbocharged and the 2.4L L4 Turbocharged. Each part is matched to the engine(s) it fits.
Do engine parts differ between 2025 Toyota 4RUNNER engines?
No. On this page every engine part fits both the 2.4L L4 ELECTRIC/GAS Turbocharged and the 2.4L L4 Turbocharged. You do not need to pick an engine to choose the right row — use the notes for position and trim.
What are the signs of engine problems on a 2025 Toyota 4RUNNER?
Common symptoms include oil spots under the vehicle, blue or white exhaust smoke, ticking from the valvetrain, or coolant mysteriously disappearing. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What oil viscosity is listed for the 2025 Toyota 4RUNNER?
Oil rows on this page include SAE 0W-20. Confirm the engine and the weight on the filler cap before you buy — high-mileage and standard fills can differ.
What should I replace at the same time?
Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
What do the market flags (US, CA, MX) on each part mean?
They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2025 Toyota 4RUNNER was originally sold in the US, the safest choice is a part marked for the US market.
How do I make sure a part fits my 2025 Toyota 4RUNNER?
Every part on this page already fits both the 2.4L L4 ELECTRIC/GAS Turbocharged and the 2.4L L4 Turbocharged. Then engine hard parts are unforgiving of guesswork — confirm the casting or engine code before ordering, because one model year can hide two different blocks. The notes column carries position and trim qualifiers where they apply.
