The oil drain plug on most 2017 Jeep models is typically a 14 mm hex head (M14 x 1.5), but exact sizes can vary by engine and model. This article outlines the common configurations and how to verify the correct size for your specific vehicle.
Common drain plug sizes by engine
Before listing specifics, note that the 2017 Jeep lineup includes multiple engines. The drain plug size is usually 14 mm across many of them, but there are exceptions. The following reflects the most frequently encountered configurations in 2017 Jeeps.
- 3.6L Pentastar V6 (the most common engine in 2017 Wranglers, Cherokees, and Grand Cherokees) — typically a 14 mm hex head; thread size commonly M14 x 1.5.
- 5.7L Hemi V8 (found in some Grand Cherokee trims) — typically a 14 mm hex head; thread size commonly M14 x 1.5.
- 3.0L EcoDiesel V6 (in select Grand Cherokee models) — commonly a 14 mm hex head with M14 x 1.5 thread; some variants may differ by year or model, so verify.
In practice, many 2017 Jeeps share the 14 mm drain plug standard, but engine and model variations can require a different size. Always confirm on your exact vehicle before servicing.
How to confirm the exact size for your Jeep
To minimize mistakes during an oil change, use these verification steps tailored for 2017 models.
- Check the owner’s manual or service manual for the recommended drain plug size and torque for your specific engine.
- Measure the hex head with a caliper or compare with a standard set to identify the correct socket size, and consider bringing a sample plug to an auto parts store to confirm.
- If you’re unsure, contact a Jeep dealer or a trusted mechanic with your VIN to obtain the exact specification for your vehicle.
Verifying the correct size before loosening the plug helps prevent cross-threading, stripped threads, or leaks after an oil change.
Summary
For most 2017 Jeep models, the oil drain plug is 14 mm in hex size (M14 x 1.5 thread). However, engine and model variations can lead to different sizes, so always verify via the owner's/service manual, inspect the plug, or consult a dealer if there is any doubt. Proper size and torque are essential to a clean, leak-free oil change.
