3. Product Overview
The ACDelco GM Original Equipment PF122 is a cartridge-style engine oil filter designed to effectively remove abrasive particles from engine oil. This helps protect critical engine components such as bearings from wear.

This image displays the ACDelco GM Original Equipment PF122 engine oil filter, which is a cartridge-style filter. It features a perforated metal core surrounding the filter media, designed to capture contaminants. A black sealing gasket is shown alongside the filter, essential for a leak-free installation.

This image provides a cross-section view of an oil filter element, emphasizing the internal structure. It highlights the use of a glass-filled nylon core, which contributes to higher strength and improved oil flow compared to traditional filter designs. This design allows for efficient capture of particles down to 30 microns.
4. Installation Instructions
Follow these steps for proper installation of the ACDelco GM Original Equipment PF122 Engine Oil Filter. Refer to your vehicle's service manual for specific procedures and torque specifications.
Tools and Materials Required:
- New ACDelco GM Original Equipment PF122 Oil Filter
- New engine oil (correct type and quantity for your vehicle)
- Oil filter wrench (specific to your vehicle's filter housing)
- Socket wrench and appropriate sockets
- Drain pan
- Clean rags or shop towels
- Funnel
- Torque wrench (recommended)
- Safety glasses and gloves
Procedure:
- Prepare Vehicle: Park the vehicle on a level surface and engage the parking brake. Allow the engine to cool down completely.
- Locate Filter Housing: Identify the oil filter housing on your engine. This is typically a canister that houses the cartridge filter.
- Drain Oil (if applicable): If performing an oil change, place the drain pan under the oil pan drain plug. Remove the drain plug and allow all old oil to drain. Once drained, reinstall the drain plug and tighten to the manufacturer's specified torque.
- Remove Filter Housing: Place the drain pan under the oil filter housing. Using the appropriate oil filter wrench or socket, carefully loosen and remove the oil filter housing cap. Be prepared for residual oil to drain out.
- Remove Old Filter: Carefully remove the old oil filter cartridge and any old O-rings or gaskets from the housing cap and the engine block.
- Clean Housing: Thoroughly clean the inside of the oil filter housing and the housing cap with a clean rag to remove any debris or old oil residue.
- Install New Gasket: Lubricate the new sealing gasket(s) provided with the new filter with a small amount of fresh engine oil. Install the new gasket(s) onto the filter housing cap and/or filter housing as specified by your vehicle's manual.
- Install New Filter: Insert the new ACDelco GM Original Equipment PF122 filter cartridge into the housing, ensuring it seats correctly.
- Reinstall Housing Cap: Carefully thread the oil filter housing cap back into place. Hand-tighten first, then use the wrench to tighten to the vehicle manufacturer's specified torque. Do not overtighten, as this can damage the housing or gasket.
- Refill Engine Oil: If you drained the engine oil, refill the engine with the correct type and quantity of new engine oil through the oil filler cap.
- Check for Leaks: Start the engine and let it run for a few minutes. Turn off the engine and check the oil level. Inspect the oil filter housing and drain plug for any signs of leaks. If leaks are present, turn off the engine immediately and re-check installation.
5. Maintenance and Replacement
The ACDelco GM Original Equipment PF122 oil filter is designed for optimal performance when replaced at regular intervals.
- Replacement Interval: Always follow your vehicle manufacturer's recommended oil and filter change intervals. These intervals are typically found in your vehicle's owner's manual.
- Driving Conditions: Consider your driving conditions. Severe driving conditions (e.g., frequent short trips, towing, extreme temperatures, dusty environments) may require more frequent oil and filter changes.
- Oil Quality: Using high-quality engine oil that meets your vehicle's specifications is crucial for filter effectiveness and engine protection.
6. Troubleshooting
If you encounter issues after installing your oil filter, consider the following common problems and solutions:
- Oil Leakage:
- Cause: Improperly seated or damaged gasket, overtightened or undertightened filter housing cap, debris on sealing surface.
- Solution: Turn off the engine. Inspect the gasket for proper seating and damage. Ensure the sealing surface on the engine block and housing cap is clean. Re-tighten the housing cap to the manufacturer's specified torque.
- Incorrect Fit:
- Cause: Incorrect filter part number for your vehicle.
- Solution: Double-check the ACDelco PF122 part number against your vehicle's requirements. Consult your vehicle's owner's manual or a reputable parts catalog.
