Mopar 4893941AD is the current water pump number for the JL's 3.6 Pentastar without the eTorque mild-hybrid system. It replaces 4893941AC and AB. FCA treats JL water pump claims cautiously: its 2024 parts guidance tells dealers to inspect before replacing, because some residue at the weep hole is normal.
Fitment
2018-and-later JL Wrangler 3.6 <strong>without eTorque</strong>. Sources disagree on model years: MoparPartsGiant lists the 4893941 series for 2020–2025 3.6 JLs, Crown lists its 4893941AB for 2018–2019 JL and 2020 Gladiator, and ExtremeTerrain lists it for 2018–2026 non-eTorque JLs. eTorque (MHEV) Jeeps use the separate 4893942 series. Confirm by VIN. Always confirm the number on your old part or run your VIN at a Mopar parts counter before you order.
Common failure symptoms
- Coolant dripping (not just residue) from the pump weep hole area
- Steady coolant loss with a pressure test pointing to the pump
- Overheating or temperature climbing under load
- Sweet coolant smell after driving

Rebuild, repair or replace?
Inspect before you replace. FCA's 2024 GPOP note for 2016–2024 3.6 Pentastar pumps (4893941, 4893942 and others) tells dealers that coolant residue at the weep-hole plug may be normal, but dripping is not, and to pressure-test when unsure. If it's dripping, replace the pump. It's not a rebuildable part. Check whether your JL has eTorque first. That decides between the 4893941 and 4893942 pumps. If you have a 2.0L turbo JL with a coolant leak, that's a different issue: Customer Satisfaction Notification ZD8 covers loose coolant inlet tube fasteners on 2021–2022 2.0L JLs.

FAQ
Is coolant residue at the weep hole a failure?
Not necessarily. FCA says some residue can be normal, but dripping is not.
How do I tell eTorque from non-eTorque?
Check your window sticker or VIN decode for the mild-hybrid (MHEV) 3.6. eTorque uses the 4893942 pump.
What years does 4893941AD fit?
Sources disagree. Listings cover anywhere from 2018 to 2026 non-eTorque 3.6 JLs. Confirm by VIN.
