The oil filter location on a 2018 Jeep Grand Cherokee varies by engine, but in most configurations it's mounted on the front side of the engine toward the passenger side and is accessible from underneath after removing the belly pan (the exact spot depends on whether you have the 3.6L V6, the 5.7L or 6.4L Hemi, or the EcoDiesel).
In this article, you'll find engine-by-engine guidance on where to look, tips for identifying the filter, and the typical tools needed to access and replace it safely.
Engine variants and typical locations
Engine choices in the 2018 Grand Cherokee vary by trim; here are common locations by engine type. Note that you may need to remove the undercarriage splash shield or belly pan to access it.
- 3.6L Pentastar V6: The oil filter is in a cartridge inside a small canister mounted on the lower front of the engine, on the passenger side. Access is from underneath the vehicle; you may need to remove the belly pan to reach the filter cap.
- 5.7L Hemi and 6.4L Hemi: The oil filter is typically a traditional spin-on unit located on the front side of the engine, commonly toward the passenger side, accessible from beneath after removing the undertray.
- 3.0L EcoDiesel: The filter is cartridge-style in a housing mounted toward the front of the engine, usually on the passenger side; access is from underneath once the splash shield is removed.
Details can vary by production year, trim level, and engine code. If in doubt, check the owner's manual or a repair guide specific to your VIN.
How to locate the exact spot on your vehicle
To pinpoint the oil filter on your exact 2018 Grand Cherokee, start with the engine code and year, then inspect the underside with proper lighting. The filter housing will have a cap or a visible canister, and the underside shield may need to come off.
- Identify your engine: 3.6L V6, 5.7L Hemi, 6.4L Hemi, or EcoDiesel. The engine code is typically found on a sticker under the hood or on the radiator support.
- Safely raise and support the front of the vehicle with jack stands and chocks, then remove the front belly pan or splash shield (if equipped).
- Look for the oil filter assembly on the front of the engine block on the passenger side; you may see a round canister with a cap (cartridge type) or a traditional spin-on filter.
If the filter is difficult to see, consult the official service manual for your exact VIN or consider having a professional perform the inspection.
What you’ll need to access and replace the filter
Before you begin, gather the tools and safety gear needed to reach and replace the filter. The exact kit depends on your engine type and filter style.
- Appropriate oil filter wrench or cap tool for the cartridge canister or spin-on filter (check your filter type).
- New oil filter and the correct grade/quantity of oil for your engine.
- Drain pan, rags, and a funnel; gloves for cleanliness.
- Jack stands, a floor jack, and wheel chocks; a sturdy light source.
- Socket set, wrenches, and any O-ring or gasket required by the filter housing.
Follow proper oil change safety procedures and dispose of old oil and filter at a recycling center. If you're unsure, have a professional perform the service.
Summary
The 2018 Jeep Grand Cherokee does not have a single universal oil filter location. The filter sits on the engine and is accessed from underneath, with the exact position varying by engine: 3.6L V6 uses a cartridge-style canister on the front passenger side; 5.7L/6.4L Hemi engines typically use a spin-on filter on the front side; EcoDiesel uses a front-mounted cartridge in a canister. Always consult the owner's manual or a repair guide for your specific VIN to confirm the location and the correct filter part. Safety first, and consider professional service if you're not comfortable performing the replacement yourself.
