Fluid Capacities and Types
 

Fuel Tank: ULSD Only
2500/3500 SB = 34 Gal
All Long Boxes = 35 Gal

Engine Oil W/ Filter: 15W-40 or 5W-40 Full Syn or Dino
12 Quarts

Power Steering: ATF+4
Power steering fluid capacities are dependent on engine/chassis options as well as steering gear/cooler options.
Depending on type and size of internal cooler, length and inside diameter of cooler lines, or use of an auxiliary
cooler, these capacities may vary.

Coolant System:
29.5 Qts or 7 Gal, 1.5 Qts (Includes 1 Qt for reservoir)

The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection.
MoparT Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene glycol base coolant
with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant
offers the best engine cooling without corrosion when mixed with 50% Ethylene Glycol and 50% distilled water
to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with
fresh properly mixed coolant solution.

Automatic Transmission: ATF+4
42RLE Serv = 4 Qts
42RLE Overhaul = 17.6 pts
45RFE/545RFE Serv = 11 pts 4x2 or 13 pts 4x4
45RFE/545RFE Overhaul = 29-33 pts (depends on options)
48RE Serv = 4 Qts
48RE Overhaul = 29-33 pts (depends on options)

Manual Transmission: ATF+4
G56 = 12 pts (diesel engine)

Transfer Case: ATF+4
NV241, NV246, NV244 = 3.4 Pts
NV271, NV273 = 4 pts
