| Without Auxiliary Heater | 13.4 Qts. (12.7L) |
| Crankcase (Includes Filter) (5) |
| 2.4L | 5.0 Qts. (4.7L) |
| 3.3L & 3.8L | 4.5 Qts. (4.3L) |

| (1) Approximate quantity listed. (2) Mopar® ATF+4 (Type 9602) is required in the 41TE automatic and T850 manual transaxles. Substitute fluids can introduce transmission problems and/or failure. (3) Estimated service refill. (4) Quantity includes heater and coolant recovery tank. (5) Only use an API Certified (GF-3) energy conserving engine oil that is certified for gasoline engines (5W-30 or 10W-30). Mopar® provides engine oils, meeting Material Standard MS-6395, that meet or exceed this requirement. On flex-fuel models, use Mopar® Flex-Fuel 5W-30 engine oil or an equivalent that meets Chrysler Standard MS-9214. Equivalent engine oils may be labeled as Multi-Fuel, Variable Fuel, Flexible Fuel, etc. SAE 5W-30 engine oil is preferred for use in Flexible Fuel engines. (6) Use only Mopar® ATF+4 Automatic Transmission Fluid (Type MS-9602) in the power steering system. Use of other Mopar® Power Steering Fluids should be avoided to ensure peak performance of the power steering system. (7) Use Mopar® Gear and Axle Lubricant (80W-90). |
