How to Change the 2007 Toyota Sienna Engine Oil

by Justin Cupler

After two failed attempts to enter the minivan world with the Toyota Van and Previa, Toyota struck gold when it released the Sienna for the 1998 model year. In 2004, Toyota redesigned the Sienna, giving it a more stylish and modern look. The 2007 Sienna came fitted with a 266-horsepower, 3.5-liter, V-6 engine. Toyota recommended changing the oil and oil filter in this engine every 5,000 miles. Failure to change the oil in accordance with the manufacturer's recommendations may lead to excessive stress on the engine's internal components, which may shorten engine life.

Step 1

Open the Sienna's hood and open the oil filler cap on top of the engine.

Step 2

Raise the front of the Sienna with a floor jack. Slide jack stands under the vehicle's subframe and lower the Toyota onto the jack stands. Remove the floor jack.

Step 3

Crawl under the Sienna and locate the oil pan, which is the metal pan on the bottom of the engine. Set a drain pan under the drain plug in the oil pan. Loosen the drain plug, using the closed end of a combination wrench, and remove the drain plug by hand.

Step 4

Remove the oil drain plug gasket and clean the drain plug, using a clean, lint-free cloth. Install a new gasket on the drain plug. Hand-tighten the drain plug into the oil pan once only slow drips of oil come from the pan. Tighten the drain plug to 30 foot-pounds, using a torque wrench and a six-point socket.

Step 5

Locate the oil filter cap, which is the circular, metal cap on the passenger-side front of the engine. Set the drain pan under the oil filter cap and loosen it with a 64 mm oil filter cup and a ratchet. Allow the oil to drain from the oil filter housing, then remove the oil filter cap and oil filter.

Step 6

Place the blade of a flat-head screwdriver under the rubber O-ring on the oil filter cap, and pry the O-ring from its groove in the cap. Remove the O-ring from the oil filter cap.

Step 7

Install a new O-ring on the oil filter cap and roll it up the cap until it seats in the groove on the cap. Set a new oil filter in the oil filter cap.

Step 8

Place a small amount of new engine oil on your finger and coat the O-ring on the oil filter cap with oil. Hand-tighten the oil filter cap onto the engine. Apply 18 foot-pounds of torque to the oil filter cap, using a 64 mm oil filter cup and a torque wrench.

Step 9

Raise the Sienna off of the jack stands, using a floor jack, and remove the jack stands. Lower the van to the ground.

Step 10

Insert a funnel into the oil filler hole and pour in 6.4 qts. of 5W-30 engine oil.

Step 11

Allow the oil to settle for approximately 1 minute and remove the oil dipstick. Wipe the dipstick clean, using a clean, lint-free cloth and reinsert the dipstick. Remove the dipstick and check that the oil level is between the two dots on the bottom of the dipstick. Add engine oil as needed. Close the oil filler cap.

Step 12

Start the engine and allow it to run for 2 to 3 minutes. Check and adjust the oil level according to the procedure in step 11. Close the Sienna's hood.

Step 13

Insert a funnel in an empty oil bottle and fill this bottle with old oil from the drain pan. Close the bottle's cap when the bottle is full. Repeat this step until all of the oil is out of the drain pan.

Step 14

Take the bottles of old oil and the filter to a local automotive oil recycling center. Many auto parts stores recycle old oil free of charge.
