2009 Chevrolet Cobalt LS Change Oil Filter
In 2005, Chevrolet introduced the Cobalt as the future replacement for the Cavalier. The following year, Chevrolet eliminated the Cavalier, and the Cobalt continued as the maker's entry-level vehicle. The 2009 Cobalt LS came fitted with a 155-horsepower, 2.2-liter, four-cylinder engine. Chevrolet equipped the Cobalt with GM's Engine Oil Life System, which displays a "Change Oil Soon" message on the instrument cluster when an oil and filter change is due. If you accidentally reset the system without changing the oil, Chevrolet recommends changing the oil at 3,000-mile intervals.

 Change Oil Filter
- Open the Cobalt's hood and remove the oil filler cap on top of the engine. This provides ventilation to the oil system for more efficient draining.
- Raise the front of the Cobalt, using a floor jack, and position jack stands under the subframe. Lower the Cobalt onto the jack stands and remove the floor jack.
- Slide under the Cobalt and locate the oil pan -- the large, metal pan on the base of the engine. Position a drain pan under the oil drain plug located on the oil pan, then loosen this drain plug with the closed end of a combination wrench. Remove the plug, by hand, and allow the oil to drain into the drain pan.
- Wipe the drain plug off with a clean, lint-free cloth. Hand-tighten the drain plug into the oil pan once only slow drips of oil come from the oil pan. Apply 18 foot-pounds of torque to the drain plug, using a torque wrench and a six-point socket.
- Raise the Cobalt off the jack stands, using a floor jack, and remove the jack stands from under the car. Lower the Chevy to the ground.
- Locate the oil filter cap -- the black, plastic cap on the driver's, front side of the engine. Remove this cap, using a ratchet and 32-mm, six-point socket. Pull the filter from the cap and place it in the drain pan.
- Insert the new oil filter in the oil filter cap and hand-tighten the oil filter cap onto the engine. Torque the oil filter cap to 18 foot-pounds, using a torque wrench and a 32-mm, six-point socket.
- Insert a funnel into the oil filler hole and pour in 5 quarts of API-certified, 5W-30 engine oil.
- Allow the oil to settle for about one minute. Pull out the engine oil dipstick and wipe the oil from it, using a clean, lint-free cloth. Reinsert the oil dipstick in the engine. Remove the oil dipstick and check that the oil level is between the "Min" and "Max" marks on the dipstick. Add oil, as needed, and close the oil filler cap.
- Start the Cobalt's engine and allow it to run for about two minutes, then shut the engine off. Check and adjust the oil level following the procedure in Step 9.
- Insert the funnel into an empty oil bottle and fill it with used oil from the drain pan. Once full, close the bottle's cap. Repeat this step until you transfer all of the oil from the drain pan into the oil bottles. Take these bottles and the old oil filter to a used automotive oil recycling center. Many auto parts stores recycle oil free of charge.
Resetting GM Engine Oil Life System
- Insert the key in the ignition. Turn the Cobalt's ignition to the "On/Run" position, but do not start the vehicle.
- Press and release the "Info" and "Reset" buttons, located on the driver's information center, at the same time. This places the DIC in the personalization menu.
- Scroll through the DIC menu by pressing and releasing the "Info" button, until you reach "Oil Life Reset."
- Hold the "Reset" button down until the DIC displays "Acknowledged." This indicates that you have correctly reset the GM Oil Life System.
- Turn the Cobalt's ignition to the "Off" position. Remove the ignition key.
