The correct oil filter part number depends on which engine the car has. The 2010 Chevy Cobalt LT could be equipped with either a 2.2-liter Ecotec engine (L61) or a 2.4-liter Ecotec engine (LUJ). There isn’t a single universal part number that covers every configuration.
Understanding the engine options
GM offered two gasoline engines in the 2010 Cobalt LT. The oil filter you need is specific to the engine hardware, so identifying the exact engine model is the first step before sourcing a replacement.
2.2L Ecotec (L61) engine
For the 2.2L Ecotec engine, the oil filter is selected to match the L61 configuration. The exact OEM number is typically listed by GM/ACDelco and will also appear on cross-reference catalogs used by auto parts stores. Since part numbers can vary by region and by specific filter design, it’s best to confirm with a parts counter using your engine code or the current filter’s branding.
Before listing options, note that there are several brands that supply filters compatible with the 2.2L engine. The following brands are commonly referenced in GM service and parts catalogs as offering cross-reference filters for this engine:
- ACDelco (GM) oil filters designed for the 2.2L Ecotec family
- Wix Filters that cross-reference to GM engines
- Bosch Premium oil filters for GM Ecotec applications
- Purolator cross-reference filters suitable for 2.2L Ecotec
- Mann-Filter equivalents that fit GM engines in this class
Concluding note: when replacing, verify the filter’s size, thread pattern, and gasket diameter to ensure a proper fit. If in doubt, bring the old filter or the vehicle’s engine code to the parts counter for an exact cross-reference.
2.4L Ecotec (LUJ) engine
The 2.4L LUJ engine uses a different oil filter specification from the 2.2L. As with the 2.2L, the precise OEM part number is listed by GM/ACDelco and appears in cross-reference catalogs used by auto parts retailers. Engine code confirmation is the quickest way to ensure you get the correct filter.
Before listing options, note that several reputable brands offer cross-reference filters suitable for the 2.4L Ecotec. The following brands are commonly cited in parts catalogs as fitting the LUJ-based Cobalts:
- ACDelco (GM) for LUJ configurations
- Wix Filters compatible with GM 2.4L engines
- Bosch Premium oil filters designed for GM Ecotec 2.4L
- Purolator cross-reference filters for the 2.4L LUJ
- Mann-Filter equivalents suitable for GM Ecotec LUJ
Concluding note: match the filter to the LUJ engine by verifying the thread size, gasket diameter, and overall housing dimensions. If you’re unsure, consult the current filter packaging or your local parts specialist using your VIN and engine code.
How to confirm the exact part number for your Cobalt
Because the 2010 Cobalt LT can use two different engines, the simplest way to guarantee you get the right filter is to identify the engine code and cross-reference it with reputable parts catalogs. The steps below help you pinpoint the correct part number quickly.
- Locate the engine code. It is typically stamped on the engine block or listed on the under-hood information label. Common codes are L61 for 2.2L and LUJ for 2.4L.
- Check your current filter. If you still have the original filter, the part number is usually printed on its label.
- Use a trusted parts catalog or retailer search. Enter the year, make, model, and engine code (L61 or LUJ) to pull the exact GM/ACDelco part number and cross-reference options.
- Compare dimensions. Make sure the chosen filter matches thread size, gasket diameter, and length to fit your housing.
- If shopping in person, bring the VIN or the old filter to the parts desk. They can pull the exact part number for your vehicle configuration.
Concluding note: using the engine code (L61 or LUJ) is the fastest way to ensure you’re ordering the correct oil filter. If you’d like, share your engine code or VIN and I can help identify the precise part number from GM/ACDelco and reliable cross-reference brands.
Summary
The 2010 Chevy Cobalt LT does not have a single oil filter part number. The correct filter depends on whether the car has the 2.2L Ecotec (L61) or the 2.4L Ecotec (LUJ). Identify the engine code, then use GM/ACDelco part catalogs or trusted cross-reference sites from brands like Wix, Bosch, Purolator, and Mann to determine the exact part number. Always verify thread size, gasket diameter, and filter dimensions before purchasing.
