The standard oil filter cap size for most 2019 Jeep Cherokee models is 65mm in diameter.
In practice, the Cherokee offers multiple engines (notably the 2.4L Tigershark inline-4 and the 3.2L Pentastar V6) that use a cartridge-style oil filter mounted in a cap. To remove the cap you’ll typically need a 65mm oil filter cap wrench/socket (14-flute designs are common). Some variants or markets may use a different size; always verify by checking the service manual or measuring the cap directly on your engine.
Engine variants and filter type
The Cherokee can be equipped with different engines, and several of them use a cartridge-type oil filter held in a cap at or near the top of the engine. While 65mm is the common size for many configurations, some markets or engine codes may differ slightly. Identifying your exact engine code (for example, 2.4L Tigershark or 3.2L Pentastar) helps confirm the correct tool size.
Are all Cherokee engines the same?
No. While the two most common options in the 2019 Cherokee lineup tend to use a 65mm cap, variations by engine code or regional spec can lead to a different cap size. If in doubt, check the service manual for your exact engine code or measure the cap directly.
Standard tool size and verification
To determine your exact size, remove the oil cap and measure the outer diameter, or verify the tool size listed in the service documentation for your engine code. The 65mm cap is the most widely used standard for FCA small to mid-size engines in this era.
What you’ll need
Before listing the tools, note that having the right socket/tool makes the job easier. Gather these items:
- 65mm oil filter cap wrench/socket (14-flute common design)
- Ratchet with appropriate drive (3/8" or 1/2" as fits your vehicle) and a short extension
- Torque wrench to follow the engine's service spec for the cap (and for reassembly)
- New oil filter cartridge and any required o-rings for the cap
- Oil drain pan, rags, gloves
- Shop manual or engine code reference to confirm exact size for your model
Before listing the items, here is what you’ll typically need to remove and replace the oil filter cap:
Having the correct tools ensures you can safely remove the cap without damaging the housing or the filter.
Oil change procedure (high level)
Here is a concise guide to the basic steps, not a replacement for the full service manual:
- Warm up the engine, then place the drain pan under the oil pan and remove the drain plug to drain old oil.
- Remove the engine oil cap to relieve pressure and aid drainage.
- Use the 65mm cap wrench to remove the oil filter cap, then pull out the cartridge filter and replace with a new cartridge, including new o-rings.
- Reinstall the cap and torques to the manual, refill with the correct oil amount and grade, and check for leaks.
Note: Always follow the Jeep service manual for torque specs and exact procedure for your engine code.
Summary
For most 2019 Jeep Cherokee models, the oil filter cap size is 65mm. Confirm by engine code and consult the service manual if uncertain, especially for non-standard engines or international variants. Using the correct 65mm cap wrench makes the job straightforward and helps avoid damaging the filter housing.
