- Read the notes on each row for position, trim and spec qualifiers before you order.
- Where labor overlaps, replace the thermostat and refill with fresh coolant whenever you change a water pump or radiator; original hoses on an older vehicle are on borrowed time.

Frequently Asked Questions
How many cooling system parts fit the 2025 Toyota 4RUNNER?
Our catalog currently lists 29 cooling system parts for the 2025 Toyota 4RUNNER across 5 subcategories and 18 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 cooling system parts differ between 2025 Toyota 4RUNNER engines?
Some do. 24 parts fit every engine; the other 5 are engine-specific. Each row (and the filter at the top) shows which. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.
What are the signs of cooling system problems on a 2025 Toyota 4RUNNER?
Common symptoms include a rising temperature gauge in traffic, sweet-smelling steam, crusty deposits around hose clamps, or a heater that blows cold. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.
What should I replace at the same time?
Where labor overlaps, replace the thermostat and refill with fresh coolant whenever you change a water pump or radiator; original hoses on an older vehicle are on borrowed time.
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?
First match the engine — each row shows which engine(s) the part fits. Then replace coolant with the exact specification the manufacturer calls for — mixing chemistries can gel and block small passages. The notes column carries position and trim qualifiers where they apply.
