0W-40 or 5W-40 (6.1 V8 Hemi)

(For best performance and maximum protection under all types of operating conditions, the manufacturer only recommends full synthetic engine oils that meet the American Petroleum Institute (API) categories of SM or SM/CF, and meet the requirements of Chrysler Material Standard MS-10725. The manufacturer recommends the use of a full synthetic engine oil, such as Pennzoil Platinum® European Formula SAE 5W-40 or equivalent.)

*Note for the 6.1L engine: The oil change specification calls for 7 quarts of oil when changing the oil and filter. Some owners have reported a slight to moderate overfill reading on the dipstick when installing a full 7 quarts. The 6.1L engine drains the oil slower than other engines. Drain the old warmed oil for at least 20 minutes to get as much out as possible. We suggest adding around 6-1/2 quarts, run the engine for a few minutes, shut it down and let sit for awhile, then fill as neccessary to bring the reading to the safe area on the dipstick. The top of the safe area represent the proper “full” level. Note that adding a full 7 quarts (with filter change) will never overfill the engine to such an extent that any oil foaming or harm will result, even if the level is beyond the “safe” reading on the dipstick.

Transfer cases
(4WD/AWD Grand Cherokees only)

Grand Cherokee WK’s use three different transfer cases, identified on the interior shift console. A circular ID tag is attached to the rear of each transfer case. The ID tag provides the transfer case model number, assembly number, gear ratio and location of manufacture. The transfer case serial number also represents the date of build.

  • ATF+4 MUST always be used in vehicles that were originally filled with ATF+4.
  • ATF+4 is compatible with ATF+3 and can be used to top off vehicles that currently have ATF+2 or ATF+3.
  • DO NOT use ATF+2 or ATF+3 to top off vehicles that have ATF+4® fluid

FLUID ADDITIVES:DaimlerChrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic transmission fluids listed above. Exceptions to this policy are the use of special dyes to aid in detecting fluid leaks. Various “special” additives and supplements exist that claim to improve shift feel and/or quality. These additives and others also claim to improve converter clutch operation and inhibit overheating, oxidation, varnish, and sludge. These claims have not been supported to the satisfaction of DaimlerChrysler and these additives must not be used. The use of transmission “sealers” should also be avoided, since they may adversely affect the integrity of transmission seals.

FILTER SEAL CAUTION (545RFE):The primary oil filter seal MUST be fully installed flush against the oil pump body. DO NOT install the seal onto the filter neck and attempt to install the filter and seal as an assembly. Damage to the transmission will result. Install the new primary oil filter seal in the oil pump inlet bore. Seat the seal in the bore with the butt end of a hammer, or other suitable tool. Place replacement filter in position on valve body and into the oil pump. Install screw to hold filter to valve body. Tighten screw to 40 in. lbs. torque.

If equipped with a dipstick, use the following procedure. If your vehicle has a capped dipstick tube, it is sealed and should not be tampered with. Your authorized dealer has the proper tools to ensure that the fluid level is set properly.Check the fluid level while the transmission is at normal operating temperature. This occurs after at least 15 miles (25 km) of driving. At normal operating temperature the fluid cannot be held comfortably between the fingertips.To check the automatic transmission fluid level properly, the following procedure must be used:1. Operate the engine at idle speed and normal operating temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the brake pedal.
4. Place the gear selector momentarily in each gear position ending with the lever in P (Park).
5. Remove the dipstick, wipe it clean and reinsert it until seated.
6. Remove the dipstick again and note the fluid level on both sides. The fluid level should he between the “HOT” (upper) reference holes on the dipstick at normal operating temperature. The fluid level is only valid if there is a solid coating of oil is seen on both sides of the dipstick. If the fluid is low, add as required into the dipstick tube. Do not overfill. After adding any quantity of oil through the oil fill tube, wait a minimum of two (2) minutes for the oil to fully drain into the transmission before rechecking the fluid level.NOTE:
If it is necessary to check the transmission below the operating temperature, the fluid level should be between the two COLD (lower) holes on the dipstick with the fluid at approximately 70 F (21 C) (room temperature). If the fluid level is correctly established at room temperature, it should be between the “HOT” (upper) reference holes when the transmission reaches 180°F (82°C). Remember it is best to check the level at the normal operating temperature.CAUTION!
Be aware that if the fluid temperature is below 50°F (10°C) it may not register on the dipstick. Do not add fluid until the temperature is elevated enough to produce an accurate reading.

7. Check for leaks. Release parking brake. To prevent dirt and water from entering the transmission after checking or replenishing fluid, make certain that the dipstick cap is properly resealed. It is normal for the dipstick cap to spring back slightly from its fully seated position, as long as its seat remains engaged in the dipstick tube

You or others can be badly burned by hot engine coolant/anti-freeze or steam from your radiator. If you see or hear steam coming from under the hood, don’t open the hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the radiator or coolant bottle is hot.Engine Coolant Checks
Check engine coolant/anti-freeze protection every 12 months (before the onset of freezing weather, where applicable). If engine coolant/anti-freeze is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh engine coolant/anti-freeze.3.0 V6 – 14.0 qts.

p/n 68048953AB (formerly 5066386AA)
MSRP $21.95/gallon.The recommended mixture is 50/50 ethylene-glycol and water. Never use pure antifreeze.The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar® 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 (red/orange) or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.Notes:Antifreeze mixture must always be at least 44%, all climates year round. Maximum protection (-90d) is provided with a 68% mixture protection.Do not change the thermostat for summer or winter operation. If replacement is ever necessary, install ONLY the correct type thermostat. Other designs may result in unsatisfactory cooling performance, poor gas mileage, and increased emissions.CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less freeze protection and less corrosion protection.

CAUTION: Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.

CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

Avoid non-HOAT mixtures, such as Prestone 50/50, that claim they can be used in vehicles of “all makes, all models”.
