2013 Toyota RAV4 oil cap — what it does and how to look after it

Yes, the 2013 Toyota RAV4 absolutely uses an engine oil filler cap. Toyota’s 2013 RAV4 Owner’s Manual (AU/NZ editions) shows the oil filler cap location under the bonnet on the cylinder head cover, where it’s removed to add oil. Toyota’s service information (TIS) and the Electronic Parts Catalogue (EPC) also list a “Cap Assy, Oil Filler” for the 2013 RAV4 platforms (e.g., ZSA42/ASA44 with the 2AR‑FE petrol engine, and market‑specific variants). So the oil cap is a required, fitted component on this model.

The oil cap’s job is simple but critical. It seals the oil fill opening so engine oil doesn’t mist or splash out, keeps dust and moisture from getting into the engine, and helps maintain proper crankcase ventilation behaviour through the PCV system. On many 2013 RAV4s the cap is also labelled with the recommended viscosity (typically SAE 0W‑20 for the 2AR‑FE), which makes quick top‑ups fuss‑free. Leave it off or run a damaged cap and you can end up with oily residue around the rocker cover, a whiff of hot oil, and in some cases a rough idle from an unintended air leak.

There’s no fixed replacement interval for the cap, but it should be checked at each service (most Aussie and Kiwi schedules are every 6 months or 10,000 km, whichever comes first). A quick visual once the bonnet’s up is all it takes. Make sure it threads or twists on smoothly, seats squarely, and that the rubber seal is supple and intact.

• Signs it’s due for replacement: perished or flattened O‑ring/seal, cracks in the plastic, loose fit, oil weep around the filler neck, or a cap that won’t seat properly.
• Quick tip: wipe the cap and filler neck clean during oil changes so grit doesn’t compromise the seal.

When replacing, a genuine Toyota cap (or a high‑quality equivalent matched to the engine code) is the safest bet. The seal material and fitment profile matter, a random “near enough” cap can leak or back off. Installation is easy: after topping up, place the cap squarely, turn by hand until fully seated and snug. No spanners or gorilla‑grip required—over‑tightening can damage the cap or the cover.

If a cap goes missing, don’t keep driving. Oil can spray out and dust can be drawn in. If you must move the vehicle, only go a very short distance and fit the correct cap as soon as possible.

Popular questions about the 2013 Toyota RAV4 oil cap

Where is the oil cap on a 2013 RAV4?

It’s on the top of the engine under the bonnet, usually on the right‑hand side of the rocker cover when you’re standing in front of the vehicle. The cap is marked with an oil can symbol and often the oil grade (e.g., SAE 0W‑20).

Twist it anti‑clockwise to remove, then refit and turn clockwise until snug. No tools are needed.

What oil grade is shown on the cap?

Most 2013 RAV4 petrol models show SAE 0W‑20 on the cap, matching Toyota’s recommendation for the 2AR‑FE engine. Always confirm with the owner’s manual or service label under the bonnet for your market and engine.

If the cap text is worn off, follow the manual’s oil spec and keep the receipt label in the service book for reference.

Is it OK to drive if the oil cap is cracked or missing?

No—avoid driving without a proper cap. You risk oil loss, mess in the engine bay, and contamination. A missing cap can also upset crankcase ventilation and make the engine run poorly.

If the cap is cracked or the seal is shot, replace it promptly. It’s an inexpensive part that prevents bigger headaches.
