On the 2015 Wrangler with the 3.6-liter V6 (Pentastar), the oil filter sits on the passenger side of the engine, mounted inside a black plastic housing against the firewall. It’s accessible from beneath the vehicle or through the right-front wheel well after removing the splash shield.
Where to look in the engine bay
Locating the filter means focusing on the engine block’s side toward the firewall. Jeep uses a compact oil filter housing in this area to conceal the filter cartridge rather than a traditional spin-on canister.
- Passenger side of the engine block, near the firewall.
- Mounted to a black plastic oil filter housing rather than a visible canister.
- Accessible from underneath the vehicle or via the right-front wheel well once the splash shield is removed.
The arrangement is typical for 2015 Wranglers with the 3.6L V6, though access may vary slightly with aftermarket parts or trim levels.
How to service the oil filter
Replacing the filter involves removing the housing cap and swapping the internal cartridge. This process requires the right tools and some basic precautions to avoid spills or leaks.
- Raise and support the vehicle securely; remove the front underbody splash shield if present.
- Place a drain pan under the engine to catch used oil.
- Turn the oil filter housing cap counterclockwise with the appropriate tool to release it.
- Remove the old filter cartridge and inspect the area for debris.
- Install a new cartridge, inspect or replace the O-ring on the cap, and reseat the cap.
- Tighten to the manufacturer’s specification, refill engine oil as needed, and check for leaks after startup.
Note: Always consult your owner’s manual or service manual for the exact torque specifications and cap tool size, as these details can vary by model year or engine variant.
Practical notes for Wrangler owners
If your Wrangler has aftermarket skid plates or extended splash guards, you may need to adjust how you access the housing. Proper disposal of used oil at a recycling facility is essential, and keep the area clean during the process to avoid contaminating components.
Summary
The oil filter on a 2015 Jeep Wrangler V6 is located on the passenger side of the engine, inside a black housing against the firewall. It’s not a traditional front-mounted spin-on filter; instead, you replace the cartridge inside the housing, with access from beneath the vehicle or through the right-front wheel well after removing the splash shield. Following the correct steps and torque specifications will ensure a proper oil change and seal.
