JL and Gladiator maintenance parts in this lookup overlap the JK list because the 3.6 still uses Mopar OAT coolant and the cartridge oil filter. 68163849AB is the 50/50 premix of the 10-year/150,000-mile formula. 68191349AC is the cartridge filter with the O-ring, for the flat-bottom housing.
The overlap is the fluid and the filter, not the cooling hardware. A JL thermostat housing is 4893926AH, not the JK housing 5184651AJ. Use this page for what goes back into the system. Use the JL cooling and engine pages for the parts that leaked.
eTorque or not, the coolant specification is the point of this page. Do not top a JL with leftover universal green because a housing job only needed a gallon of something. The early-JK nipple filter is uncommon here, but a cartridge ordered for a different housing still will not seal. Match the housing on the truck, and torque the cap to 18 ft-lbs.

When to replace
Refill with 68163849AB, or the same OAT spec from a sealed jug, whenever a housing, pump, or oil-cooler job drains the system. Change 68191349AC at the oil interval and whenever the housing is serviced. Use a new O-ring. If you do not know what coolant is in the truck, drain and fill rather than mixing.
Safety
Open the cap cold. Coolant is toxic. On eTorque trucks a coolant job can put your hands near the belt-starter and orange high-voltage cables. Identify the truck first, and leave the 48-volt side to a dealer or a qualified tech. If the oil is milky, do not drive it until you know whether the cooler is passing coolant into the oil.
