The size of the oil filter on a 2014 GMC Sierra depends on the engine installed. In most configurations, GM used a standard 3/4-16 threaded oil filter, with the canister length varying by brand and model. Always verify by checking the existing filter or your vehicle’s VIN-based specifications.
The 2014 Sierra was offered with several engines, including a 4.3L V6, a 5.3L V8, and a 6.2L V8. While the thread pattern is generally the same across these engines, the exact filter body length and capacity can differ by filter design and aftermarket options. This article outlines the general sizing approach and how to confirm the right filter for your truck.
Engine options and filter basics
Below are the common configurations for the 2014 Sierra and the general guidance on oil filter sizing. Use this as a quick reference, but always confirm with your VIN or the OEM specifications for your exact build.
- 4.3L V6 (Vortec) — uses a standard oil filter with 3/4-16 threads; body length varies by brand, typically in the mid-range for common filters.
- 5.3L V8 — uses the same general 3/4-16 thread; filter length varies by brand and design, but is usually similar to other GM V8s of that era.
- 6.2L V8 — also uses a standard 3/4-16 thread; some brands offer longer canisters, depending on the filter design.
Note: Engine variants and aftermarket filters can affect the exact length and capacity. Always confirm with the specific part number or by checking the old filter’s dimensions.
How to identify and confirm the right filter
Use these steps to confirm the correct oil filter for your truck:
- Identify your engine code and size (4.3L, 5.3L, or 6.2L) from the glove box or vehicle documentation.
- Remove and inspect the old filter for any part numbers or stamped specifications; measure the thread diameter to confirm a standard GM fit (commonly 3/4-16).
- Consult the owner's manual, dealership service portal, or a reputable parts retailer to cross-reference by engine code, VIN, or the exact filter model.
Following these steps helps ensure you select a filter that matches both the thread size and the overall length required for proper fit and oil flow.
