The 2012 Jeep Wrangler is a legendary vehicle, renowned for its off-road prowess and rugged dependability. Maintaining its engine's health is paramount to ensuring its longevity and performance. A crucial component in this maintenance routine is the oil filter. Understanding the correct oil filter part number for your 2012 Wrangler is essential for ensuring proper fit, filtration, and ultimately, the well-being of your engine. This comprehensive guide will delve into everything you need to know about the 2012 Jeep Wrangler oil filter part number, covering its importance, different options, installation tips, and more.
Why Knowing the Correct Oil Filter Part Number Matters
The Definitive Guide to the 2012 Jeep Wrangler Oil Filter Part Number
Using the correct oil filter is not merely a suggestion; it's a necessity. The oil filter's primary function is to remove contaminants from the engine oil, preventing premature wear and tear on critical engine components. Using the wrong filter can lead to several problems:
- Poor Filtration: An incorrect filter may not have the correct micron rating, allowing smaller particles to bypass the filter and circulate through the engine.
- Improper Fit: A mismatched filter may not seal correctly, leading to oil leaks and reduced oil pressure.
- Reduced Oil Flow: Some filters may have a restricted flow rate, starving the engine of oil and potentially causing damage.
- Engine Damage: In severe cases, using the wrong filter can lead to catastrophic engine failure.
Therefore, knowing and using the correct oil filter part number for your 2012 Jeep Wrangler is a non-negotiable aspect of vehicle maintenance.
Decoding the 2012 Jeep Wrangler Oil Filter Part Number
The 2012 Jeep Wrangler came equipped with two different engine options, each requiring a specific oil filter:
-
3.6L Pentastar V6 Engine: This engine, the most common for the 2012 Wrangler, uses a specific cartridge-style oil filter. The Mopar part number is 68079744AA (superseded by 68191349AA). This is the primary part number you should be looking for. Aftermarket brands will have their own equivalent part numbers that cross-reference to this Mopar number.
-
3.8L V6 Engine: A carryover from previous years, some early 2012 Wranglers might have been equipped with this engine. The correct oil filter for this engine is a spin-on type. The Mopar part number is MO-041 (superseded by MO-041A or MO-349). Again, aftermarket equivalents exist.
Confirming Your Engine Type: The easiest way to confirm which engine your 2012 Wrangler has is to check your VIN (Vehicle Identification Number). The engine code is usually included within the VIN. You can also check your owner's manual or look at the engine itself. The 3.6L Pentastar has a distinctive engine cover, while the 3.8L is a more traditional V6 design.
Finding Aftermarket Equivalents
While using a genuine Mopar oil filter is always a safe bet, many reputable aftermarket brands offer equivalent filters that meet or exceed OEM specifications. Some popular brands and their cross-referenced part numbers for the 3.6L Pentastar V6 include:
- FRAM: CH11665
- Purolator: L26317
- Mobil 1: M1-113A
- WIX: 57060
- Bosch: 3330
For the 3.8L V6, common aftermarket equivalents include:
- FRAM: PH3614
- Purolator: L14610
- Mobil 1: M1-102
- WIX: 51348
- Bosch: 3300
Important Considerations When Choosing an Oil Filter
Beyond just the part number, consider these factors when selecting an oil filter:
- Filter Media: Look for filters with high-quality synthetic or blended media for superior filtration and longer service life.
- Micron Rating: A lower micron rating indicates finer filtration, but it can also restrict oil flow. A good balance is key.
- Construction Quality: Ensure the filter is well-built with durable materials to withstand the pressures and temperatures of the engine.
- Reviews and Ratings: Read reviews and ratings from other users to get an idea of the filter's performance and reliability.
Step-by-Step Guide: Changing the Oil and Filter on a 2012 Jeep Wrangler (3.6L Pentastar V6)
This guide focuses on the 3.6L engine as it was the more prevalent option in 2012. Always consult your owner's manual for specific instructions and safety precautions.
Tools and Materials:
- New oil filter (Mopar 68191349AA or equivalent)
- New engine oil (typically 5W-20 or 5W-30, consult your owner's manual for the recommended grade)
- Oil filter wrench (specific to the cartridge-style filter housing)
- Socket wrench and socket for the drain plug
- Drain pan
- Funnel
- Gloves
- Rags or shop towels
- Torque wrench (optional, but recommended)
Procedure:
- Warm Up the Engine: Run the engine for a few minutes to warm the oil, making it flow more easily.
- Prepare the Vehicle: Park the Wrangler on a level surface and engage the parking brake.
- Locate the Oil Drain Plug: It's typically located on the bottom of the oil pan.
- Position the Drain Pan: Place the drain pan under the drain plug.
- Remove the Drain Plug: Carefully loosen the drain plug with the socket wrench and socket. Finish removing it by hand, being prepared for the oil to flow out.
- Allow the Oil to Drain: Let the oil drain completely, which may take 15-30 minutes.
- Locate the Oil Filter Housing: The oil filter housing is typically located on top of the engine, often near the front.
- Remove the Oil Filter Housing Cap: Use the oil filter wrench to loosen and remove the oil filter housing cap. Be careful, as some oil may still be present.
- Remove the Old Oil Filter: The old oil filter cartridge will be inside the housing cap. Gently pull it out.
- Replace the O-Rings: The oil filter housing cap usually has one or two O-rings. Replace these with the new O-rings that come with the new oil filter. Lubricate the new O-rings with fresh engine oil.
- Install the New Oil Filter: Insert the new oil filter cartridge into the housing cap.
- Reinstall the Oil Filter Housing Cap: Screw the housing cap back onto the engine by hand, then tighten it with the oil filter wrench to the specified torque (check your owner's manual or the filter housing for the torque specification). Overtightening can damage the housing.
- Reinstall the Drain Plug: Clean the drain plug and install a new crush washer (if applicable). Tighten the drain plug to the specified torque (check your owner's manual).
- Add New Oil: Use a funnel to pour the correct amount of new engine oil into the engine. Consult your owner's manual for the correct oil capacity.
- Check the Oil Level: Use the dipstick to check the oil level. Add more oil if necessary to reach the "full" mark.
- Start the Engine: Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter housing.
- Recheck the Oil Level: Turn off the engine and let it sit for a few minutes. Recheck the oil level and add more oil if needed.
- Dispose of Used Oil Properly: Take the used oil and filter to a recycling center or auto parts store for proper disposal.
Troubleshooting Common Issues
- Difficulty Removing the Oil Filter Housing Cap: Ensure you are using the correct oil filter wrench and applying even pressure. If it's stuck, try tapping the wrench with a hammer.
- Oil Leaks After Changing the Oil: Double-check that the drain plug and oil filter housing cap are tightened to the correct torque specifications. Also, ensure that the O-rings on the oil filter housing cap are properly installed and lubricated.
- Incorrect Oil Level Readings: Make sure the vehicle is on a level surface and that you are allowing enough time for the oil to settle before checking the level.
