This automotive maintenance tutorial was specifically written to assist owners of the second generation 2016, 2017, 2018 and 2019 GM Chevrolet Cruze in changing the motor oil and replacing the oil filter on the Ecotec LE2 1.4 liter turbocharged inline four cylinder gasoline engine. (The procedure may be the same or very similar for the LH7 1.6L L4 diesel engine.)

Owners of other General Motors vehicles from Chevrolet, Buick, GMC, Cadillac and Holden such as the Sonic, Spark, Malibu, Impala, Volt, Bolt, Camaro, Corvette, Trax, Equinox, Blazer, Suburban, Tahoe, Traverse, Colorado, Silverado, Express, TrailBlazer, Encore, Regal TourX, Envision, Enclave, LaCrosse, Cascada, Sierra, Canyon, Acadia, Terrain, Yukon, Savana, XT4, XT5, XT6, Escalade, CT5, CTS-V, XTS, CT6, ATS, Astra and Commodore may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) oil filter part number is genuine GM 12640445 or ACDelco PF64.

Other compatible replacement oil filters for the General Motors Ecotec LE2 turbo 1.4L I4 engine with their part numbers include the following: Bosch 3334, K&N HP-1017, Purolator L12222, Mobil 1 M1-113 and Royal Purple 10-48.

The tools and other items needed to complete this procedure include a floor jack, two jack stands, a 15mm socket with a 3/8" drive ratchet, a Lisle 63600 oil filter wrench (optional), a used oil catch container, an automotive funnel and five quarts of new SAE 0W-20 oil.

The total oil capacity specification for an oil change with a filter replacement for the LE2 1.4L engine is listed in the owner's manual as 4.2 U.S. quarts (or 4.0 liters).

The first steps are to warm up the engine for a few minutes, park the vehicle on a level surface, shift the transmission into "Park" and turn off the ignition.

Warming up the engine will help suspend any contaminants within the old oil and also allow it to drain out more quickly.

Engage the emergency / parking brake and place wheel chocks on both sides of the rear tires to prevent the car from moving.

Then open the hood, twist off the round black plastic oil fill cap in the counterclockwise direction and partially lift out the yellow plastic handled oil dipstick an inch or two.

Removing the oil filler cap and partially removing the dipstick will help prevent a vacuum from forming and allow the old oil to drain out more quickly.

Oil Pan & Oil Filter
For easier access to the oil drain bolt and the oil filter location, you'll need to raise the front of the vehicle.

Carefully raise the front of the car by using the floor jack and then securely support it with at least two jack stands.

Please do not solely rely on the floor jack to support the vehicle!

The black metal oil pan, silver metal oil drain bolt and old oil filter are situated behind an exhaust pipe and closer to the passenger side of the vehicle.

Loosen Oil Drain Bolt
The silver metal oil drain bolt is located at the rear of the black metal oil pan.

Slide the used oil catch basin to just below the drain plug.

Loosen the oil drain bolt by turning it in the counterclockwise direction with a 15mm socket and a 3/8" drive ratchet.

Twist Off Old Oil Filter
Be careful when you remove the oil drain bolt.

The old oil might still be hot enough to burn your fingers depending on how long you warmed up the engine.

Carefully spin out the drain bolt by hand.

Allow the old oil to drain out for at least a few minutes or until the flow slows down to just an occasional drip.

Inspect the metal washer or "gasket" on the oil drain bolt and replace it if necessary.

Clean off the area around the oil drain port with a clean rag or paper towel.

Re-insert the oil drain bolt and spin it in a few turns by hand in the clockwise direction to help prevent it from becoming cross threaded.

Tighten the oil drain bolt to just a small fraction of a turn past finger tight.

If you insist on using a torque wrench, the service manual specification for the 15mm oil drain bolt is 18 lb-ft of torque.

Try to avoid over tightening the oil drain bolt to prevent from damaging the aluminum threads in the oil pan which may lead to an oil leak.

The old oil filter is situated near the oil pan closer to the front of the engine bay.

Carefully slide the used oil catch container forward to just below the old oil filter.

Twist off the old oil filter in the counterclockwise direction.

Move Basin Forward
If you have trouble removing a stubborn or stuck old oil filter that was over tightened at the GM factory, a dealership service department or a quick lube oil change business, I highly recommend using the Lisle 63600 oil filter wrench.

Attach the oil filter wrench to a short extension bar and a 3/8" drive ratchet.

Twist off the old oil filter in the counterclockwise direction.

Allow the old oil to drain out from the filter receptacle for at least a few minutes.

Dip Finger In New Oil

Lubricate Rubber O-Ring

Twist On New Oil Filter
Make sure that the old rubber o-ring gasket from the old filter is not still attached to the engine.

Dip your finger into some new oil and lubricate the rubber o-ring gasket on the new oil filter.

Lubricating the rubber gasket will help the filter form a better seal and also make it easier to remove during the next oil change.

I recommend buying the original genuine GM oil filter which is part number ACDelco PF64.

Carefully twist on the new filter in the clockwise direction by hand.

Then tighten the new filter to about 1/4 to 1/3 turn past finger tight.

Try to avoid over tightening the new oil filter to prevent from damaging the rubber o-ring gasket which could result in an oil leak.

Double check that the oil drain bolt and the new filter are properly tightened before moving on to the next steps.

Pour In New Oil
Carefully lower the vehicle from the jack stands by using the floor jack.

Insert an automotive funnel into the oil filler hole.

The total oil capacity specification for the Ecotec LE2 1.4L turbocharged I4 engine is 4.2 U.S. quarts (or 4.0L).

Since it is much better to have slightly less oil than necessary in an engine than to run an engine that has been overfilled with oil, I recommend only pouring in about 3.5 to 4 U.S. quarts of the engine's 4.2 U.S. quarts total capacity.

Slowly pour in the new SAE 0W-20 oil into the automotive funnel.

(If you live in a very hot or a very cold climate, a thicker or thinner viscosity oil might be required. Please check the chart in your owner's manual for the appropriate viscosity.)

Check Oil Level
Temporarily replace the oil filler cap by twisting it on in the clockwise direction.

Push the oil dipstick back down into place.

Start the engine and allow it to warm up to near operating temperature for at least a few minutes in order to distribute the new oil.

Turn off the engine and allow the new oil to drain down to the oil pan for at least 10 to 15 minutes.

Pull the dipstick out of the engine, wipe it clean, fully re-insert the dipstick and then pull it out again to check the oil level.

Oil Change Complete
If necessary, slowly pour in more oil up to the 4.2 U.S. quarts total capacity and repeatedly check the level on the reservoir.

You may not need to pour in the entire 4.2 U.S. quarts in order for the level on the dipstick to reach the "Full" or "Max" (Maximum) level indicated by the line at the top of the cross-hatched area and the upper hole in the tip of the dipstick.

Replace the dipstick and make sure that the oil fill cap is securely in place.

To reset the "Engine Oil Life System" and clear the "Change Engine Oil Soon" message, follow these steps: 1. Change the driver information center display screen ("DIC") to display the "Remaining Oil Life". 2. Press and hold the "SET/CLR" button or press and hold the (check mark) on the display while the oil life display is active. 3. The oil life percentage should reset to 100%. 4. The "Change Engine Oil Soon" message should be cleared.

(Whether your Cruze has a "SET/CLR" or a "" button on your cluster depends on your vehicles trim level and / or model year.)

An alternative method to resetting the oil life system can be done by following these instructions: 1. Turn the ignition to the "Off" setting. 2. Fully press down and release the accelerator (gas) pedal at least three times within five seconds. 3. Switch the ignition switch to the "On" position to verify that the "Change Engine Oil Soon" message has disappeared.

Please be sure to write down the date and mileage of the oil change in your vehicle's service records.

The oil change interval specification in the owner's manual on the "Normal" service schedule is to replace the oil and filter every 7,500 miles (or every 12,000 kilometers).
