The oil filter in a 2018 Chrysler Pacifica sits in the engine bay on the passenger side, inside a filter housing rather than a traditional spin-on canister.
The 2018 Pacifica uses the 3.6L Pentastar V6 in most configurations. That engine applies a cartridge-style oil filter inside a housing, and access is typically from the top of the engine bay. Depending on trim and how much clearance you have, you may need to remove a small amount of protective shielding or reach around components to reach the housing.
Where to look in the engine bay
To locate the filter housing quickly, use these cues as a guide. The following describes a typical arrangement for the 3.6L Pentastar in the Pacifica, but variations can occur by trim or production changes.
- Look toward the passenger side of the engine, near the front of the bay.
- Identify a cylindrical housing with a removable cap or cover, often made of plastic or metal.
- The housing sits near the intake manifold and away from the oil pan; it is not the traditional bottom-mounted spin-on filter.
Finding the filter housing confirms you’ve located the oil filter area. Once you’ve found it, you’ll proceed to remove and replace the cartridge inside the housing during a filter change.
How to service or replace the oil filter
Before attempting a filter change, note that some Pacifica models require accessing the housing from above, while others may need you to remove a splash shield or small panels for clearance. Always consult the owner’s manual or a service manual for your exact trim if in doubt. Here are general steps to expect for cartridge-type filters in this engine family.
- Park safely, let the engine cool, and gather the replacement filter cartridge and new gasket/seal if required by your housing design.
- Access the filter housing cap (from the engine bay). Depending on your setup, you may need to remove a cover or shield first.
- Remove the housing cap and take out the old cartridge. Be prepared for some residual oil to drain from the housing.
- Install the new cartridge, ensuring it seats properly and any seals or gaskets are in place. Replace the cap and tighten to the manufacturer’s specification.
- Replenish engine oil to the recommended level after completing the filter replacement, then run the engine and check for leaks.
If you’re unsure about the procedure or don’t have the right tools, it’s wise to have a professional handle the change to avoid leaks or improper seating of the cartridge.
Summary
In a 2018 Chrysler Pacifica, the oil filter is located in the engine bay on the passenger side inside a filter housing (not a traditional spin-on canister). Access may require moving aside a shield or panel, depending on trim. Replacement involves removing the housing cap, replacing the cartridge, and resealing the cap, followed by a standard oil refill and leak check.
