Locating the 2015 Jeep Grand Cherokee oil filter requires understanding the undercarriage layout specific to the third-generation WK2 platform. This component is a critical part of the scheduled maintenance routine, ensuring the 6.4-liter HEMI V8 or the 3.6-liter Pentastar V6 engines remain properly lubricated and free from damaging debris. Accessing the filter involves positioning the vehicle safely and identifying the housing situated near the front of the engine bay.
Standard Location Under the Vehicle
For the vast majority of 2015 models, the oil filter is positioned vertically on the passenger side of the engine compartment, close to the front. It is mounted to the engine block or a nearby mounting bracket, making it distinct from the oil drain plug, which is located on the underside of the oil pan. You will need to crawl underneath the vehicle or use a lift to get a direct line of sight to the cylindrical canister.
Identifying the Correct Housing
The filter housing is a metal canister, approximately 3 to 4 inches in diameter, featuring a single bolt securing it to the engine block. This bolt is usually a large hex head, often requiring a box-end wrench or a specialized oil filter wrench for removal. The housing is typically situated high on the engine to avoid contact with road debris, but low enough to be accessed without removing other components.
Tools Required for the Task
Before beginning the replacement, assembling the right tools ensures a clean and efficient procedure. You will need a new oil filter specifically rated for the 2015 Grand Cherokee, a drain pan for the old oil, and an oil filter wrench. Additionally, a socket set with a breaker bar is necessary to loosen the drain plug, while a torque wrench is essential for tightening the new filter to the manufacturer's specifications to prevent over-tightening or leaks.
Recommended Equipment List
New OEM or aftermarket oil filter
Oil filter wrench (strap-type or socket-style)
Socket set and breaker bar
Drain pan capable of holding over a quart of oil
Torque wrench
Jack and jack stands or ramps
Step-by-Step Replacement Procedure
Begin by lifting the front of the vehicle securely using a jack and jack stands or ramps, ensuring the vehicle is stable before crawling underneath. Locate the oil drain plug underneath the oil pan, place your drain pan beneath it, and remove the plug to drain the old oil. While the oil is draining, use the oil filter wrench to loosen the bolt on the filter housing, being prepared for some initial resistance due to vacuum pressure.
Installation Best Practices
Once the old filter is removed, prepare the new one by applying a thin layer of fresh motor oil to the gasket. This ensures a proper seal and prevents dry starts. Screw the new filter onto the housing by hand, tightening it securely—usually about 3/4 of a turn past hand tight—before using the wrench to finalize the torque to the specifications outlined in the owner’s manual. Reinstall the drain plug and lower the vehicle to begin the fill cycle.
Common Challenges and Solutions
Owners may encounter difficulty removing a stubborn filter due to corrosion or previous over-tightening. In such cases, applying penetrating oil and allowing it to sit for several minutes can loosen the rust and grime. Another challenge involves clearance issues with the brake line or steering components, which may require slight maneuvering of the vehicle or the use of a swivel socket to achieve the necessary angle for removal.
