Finding Your AC Delco Filter by Vehicle Information

The fastest way to find the correct AC Delco oil filter is to enter your vehicle's year, make, and model into AC Delco's online filter finder tool at acdelco.com. The tool returns the exact filter part number you need, along with cross-reference numbers if you want to compare it to other brands. You will need your vehicle's year, make, model, and engine size — information you can find on your registration, in your owner's manual, or on a sticker inside your driver's door jamb.

If you do not have access to the internet or prefer to speak with someone, call an AC Delco dealer parts department directly. Give them the same vehicle information, and they will provide the part number over the phone. Many dealers can also tell you the current price and whether the filter is in stock at that location.

A third option is to visit an auto parts retailer like AutoZone, O'Reilly, NAPA, or Advance Auto Parts in person or online. Enter your vehicle information into their system, and they will show you AC Delco filters that fit, along with the part number and price. Some retailers will cross-reference the part number to show you equivalent filters from other manufacturers if you want to compare options.

Understanding AC Delco Part Numbers

AC Delco oil filters use a numbering system that tells you the filter's size, thread type, and performance level. A typical part number looks like PF2232 or PF2232E. The letters and numbers together identify which vehicles the filter fits and what its specifications are.

The same part number will work for multiple vehicle models if they share the same engine. For example, a filter that fits a 2015 Chevrolet Silverado may also fit a 2015 GMC Sierra if both have the same engine size. The part number, not the vehicle name, is what matters — two different engines in the same vehicle model year may need different filters.

When you look up your filter online or by phone, write down the full part number. This number is what you will use to order the filter, compare prices, or verify you have the right one when you pick it up.

Using the AC Delco Website Lookup Tool

Go to acdelco.com and look for the "Find Parts" or "Parts Finder" section, usually located in the top navigation menu. Click on "Oil Filters" or "Filters" from the category list. You will see a form asking for your vehicle's year, make, and model.

Select your vehicle year from the dropdown menu first. Then select the make (Chevrolet, GMC, Cadillac, etc.). After you choose the make, the model dropdown will populate with only the models available for that year and manufacturer. Select your model, and if the form asks for engine size, choose the option that matches your vehicle. If you are unsure of your engine size, check your owner's manual or the sticker inside your driver's door.

Once you submit the form, the tool will display the AC Delco filter part number, a description of the filter, and often a photo. Some versions of the tool also show where to purchase the filter and may display the manufacturer's suggested retail price. Write down the part number before you leave the page.

Looking Up Filters at Auto Parts Retailers

Most national auto parts chains have their own online lookup systems. Visit AutoZone.com, OReillyAuto.com, NAPAonline.com, or AdvanceAutoParts.com and look for a "Find Parts" or search bar. Enter your vehicle year, make, and model, then select "Oil Filters" from the category.

The retailer's system will show you AC Delco filters that fit your vehicle, listed by part number and price. Many retailers also display the filter's specifications (such as micron rating or bypass valve type) and customer reviews. Some will show you equivalent filters from other brands side by side so you can compare prices.

If you prefer to shop in person, visit a local store and ask a staff member to look up your filter. Bring your vehicle keys or registration so they can confirm your vehicle information. Most stores can tell you whether the filter is in stock and can hold it for you if you need to come back later.

Calling an AC Delco Dealer Parts Department

Find an AC Delco dealer in your area by searching "Chevrolet dealer near me," "GMC dealer near me," or "Cadillac dealer near me" depending on your vehicle brand. Call the parts department directly — this number is usually listed on the dealer's website under "Contact Us" or "Parts."

When you call, have your vehicle's year, make, model, and vehicle identification number (VIN) ready. The VIN is a 17-character code printed on your registration and on a sticker inside your driver's door. Give the parts department representative this information, and they will provide the AC Delco filter part number, price, and availability at that location.

Dealer parts departments often have the filter in stock and can set it aside for you. Some dealers offer shipping to your home or to a local service center if the part is not in stock at that location. Ask about pricing and delivery options when you call.

Cross-Referencing AC Delco Filters to Other Brands

If you want to compare AC Delco filters to other manufacturers, use the cross-reference feature at most auto parts retailers. Once you have your AC Delco part number, enter it into the retailer's cross-reference tool, and the system will show you equivalent filters from Mobil 1, Fram, Purolator, and other brands that fit the same vehicle.

Cross-reference tools are useful if another brand is on sale, if you prefer a different filter type (synthetic versus conventional), or if you want to see the price difference between brands. The cross-referenced filters will have different part numbers but will fit your vehicle and perform the same basic function.

Keep in mind that while cross-referenced filters fit your vehicle, they may have different specifications — such as micron rating, bypass valve pressure, or anti-drainback valve design. These differences are usually minor for standard oil changes, but if you have questions about whether a cross-referenced filter meets your vehicle's requirements, ask the retailer or consult your owner's manual.

Frequently Asked Questions

What if I do not know my vehicle's engine size?

Check your owner's manual — the engine size is listed in the specifications section. You can also find it on a sticker inside your driver's door jamb, or call your vehicle's dealer with your VIN and they will tell you. Engine size is usually measured in liters (like 5.3L or 2.0L) or cubic inches.

Can I use an AC Delco filter from a different vehicle year?

No. Oil filters are designed for specific engine sizes and thread types. Using the wrong filter can result in poor oil flow or leaks. Always use the part number that matches your exact vehicle year, make, model, and engine size.

Do I need to buy the filter from an AC Delco dealer?

No. AC Delco filters are sold at most auto parts retailers, online marketplaces, and some general retailers. Once you have the part number, you can purchase it from any retailer that carries it. Prices may vary between retailers, so comparing before you buy can save money.

What is the difference between AC Delco PF and ACF filter numbers?

AC Delco uses different letter prefixes for different filter types and applications. PF filters are standard oil filters for most vehicles. ACF filters are for specific applications. The lookup tool will show you which type your vehicle needs — do not substitute one for the other without confirming with a dealer or parts specialist.

Can I look up a filter if I only have my VIN?

Yes. Most auto parts retailers and AC Delco dealers can look up your filter using only your VIN. The VIN contains all the information needed to identify your vehicle's year, make, model, and engine size. You can provide the VIN over the phone, online, or in person.
