The 2010 Prius oil filter location and part number

The 2010 Toyota Prius uses a cartridge-style oil filter housed in a plastic canister on top of the engine. The part sits directly above the engine block, toward the front of the vehicle on the driver's side. Toyota part number 04152-YZZA6 is the OEM filter for this model year, though aftermarket filters from Fram, Bosch, and Mobil also fit and work reliably.

The cartridge design means you remove the entire plastic housing cap rather than unscrewing a spin-on filter. This is simpler than it sounds once you know where to grip, but the first time catches most people off guard because the filter doesn't look like what they expect.

Key Takeaways

  • The 2010 Prius oil filter is a cartridge type housed in a plastic canister on top of the engine, not a traditional spin-on filter.
  • You will need a 74mm filter wrench (or a strap wrench) to remove the canister cap, a drain pan, and a new filter element plus a new rubber gasket.
  • The job takes 10 to 15 minutes and requires no special tools beyond the filter wrench and a basic socket set to access the drain plug.
  • The drain plug is located on the underside of the engine and holds about 3.7 quarts of oil when you empty it completely.

Tools and supplies you will need

Gather these items before you start: a 74mm oil filter wrench (sometimes called a cartridge filter wrench), a drain pan that holds at least 4 quarts, a new filter element (Toyota part 04152-YZZA6 or equivalent), a new rubber gasket that comes with most replacement filters, a socket wrench set, jack stands if you need clearance under the vehicle, and fresh oil that meets Toyota's 0W-20 specification for the 2010 Prius.

The 74mm wrench is the critical piece. It looks like a large socket with a handle and grips the canister cap from the top. You can find them at any auto parts store for $15 to $25, or use a strap wrench if you already own one. Do not attempt to remove the canister cap by hand or with pliers — you will strip the plastic housing.

Steps to remove the old filter

First, locate the oil filter canister on top of the engine. It is a black plastic cylinder about 3 inches tall, positioned toward the front-left of the engine bay. Open the hood and look directly above the engine block — you cannot miss it once you know what you are looking for.

Place your drain pan underneath the canister. Using the 74mm filter wrench, turn the cap counterclockwise until it comes free. The cap will lift off, and oil will drain into the pan below. This is normal — the canister holds some oil even after you have drained the pan. Let it drip for a minute or two.

Once the cap is off, you will see the filter element inside — a white or yellow cylindrical cartridge. Lift it straight out. Underneath the element, you will find a rubber gasket (a flat ring) sitting in the bottom of the canister. Remove this gasket as well. Wipe the inside of the canister clean with a lint-free cloth or paper towel.

Installing the new filter and gasket

Take the new filter element and the new rubber gasket that came with it. Place the gasket in the bottom of the canister first, pressing it gently so it sits flat. The gasket should fit snugly in the groove at the base of the canister.

Insert the new filter element straight down into the canister, pressing it down until it seats firmly. You should feel a slight resistance as it bottoms out. Do not force it — if it does not seat smoothly, remove it and check that the gasket is positioned correctly.

Screw the canister cap back on by hand first to avoid cross-threading. Once hand-tight, use the 74mm wrench to tighten it an additional three-quarter turn. Do not over-tighten — the plastic canister can crack if you explore too much force.

Draining and refilling the oil

While the filter drains, locate the oil drain plug on the underside of the engine. You may need to raise the vehicle slightly with a jack and find it on jack stands for comfortable access. The drain plug is a 17mm bolt on the bottom of the oil pan, toward the rear of the engine.

Place your drain pan underneath the plug. Using a socket wrench, turn the plug counterclockwise until it comes free by hand. Let the old oil drain completely — this takes 5 to 10 minutes. Once the flow slows to a drip, wipe the plug clean with a cloth and reinstall it, tightening it snugly but not aggressively. A torque of 25 to 30 foot-pounds is correct, though hand-tight plus a quarter turn is close enough for most home mechanics.

Lower the vehicle back to the ground. Remove the oil filler cap on top of the engine (it has an oil can symbol on it). Pour in 3.7 quarts of 0W-20 oil. Wait a minute, then check the level on the dipstick — pull it out, wipe it clean, reinsert it fully, and pull it out again to read the level. The oil should reach the "full" mark. Add a small amount more if needed.

Starting the engine and checking for leaks

Replace the oil filler cap. Start the engine and let it idle for 30 seconds. You will see the oil pressure light on the dashboard — it should go out within a few seconds as oil circulates through the new filter. If the light stays on for more than 10 seconds, turn off the engine and wait a minute for the filter to fill, then try again.

Turn off the engine and wait 2 to 3 minutes for the oil to settle. Check the level again on the dipstick and top up if necessary. Inspect the filter canister cap and the drain plug for any drips or leaks. A small amount of seeping is normal in the first few minutes, but active dripping means you need to tighten the cap or plug slightly.

Reset the oil change reminder on your dashboard if your Prius has one. Most 2010 models have a button on the instrument cluster or steering wheel that you hold for a few seconds until the message clears.

Frequently Asked Questions

Can I use a different oil filter brand instead of Toyota OEM?

Yes. Fram TG3593, Bosch 3330, and Mobil 1 M1-110 all fit the 2010 Prius and perform well. The key is matching the 74mm cartridge size and the gasket diameter. Check the product description or ask at the parts counter to confirm the fit before you buy.

What should I do with the old oil?

Take it to an auto parts store, quick-lube shop, or municipal hazardous waste facility. Most stores that sell oil will take used oil for free. Do not pour it down a drain or into the ground — it is a hazardous material and illegal to dispose of that way in most places.

How often should I change the oil filter on a 2010 Prius?

Toyota recommends changing the oil and filter every 10,000 miles or 12 months, whichever comes first. If you drive mostly short trips or in dusty conditions, consider changing it every 5,000 miles. Check your owner's manual for the exact interval for your driving habits.

What if the filter canister cap is stuck and won't turn?

explore penetrating oil (like WD-40) around the base of the cap and wait 15 minutes. Try again with the wrench, explore steady pressure rather than jerking. If it still will not budge, tap the wrench handle gently with a rubber mallet to break the seal. Avoid hitting hard — the plastic can crack.

Do I need to replace the gasket every time I change the filter?

Yes. The rubber gasket compresses and hardens over time and will not seal properly if reused. A new gasket comes with most replacement filter elements, so you should always install it. If your filter element did not come with a gasket, buy one separately — they cost a few dollars.
