Grand Cherokee WJ's use three different 4-wheel drive 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.

The recommended mixture is 50/50 ethylene-glycol and water. Never use pure antifreeze.

Only Mopar Antifreeze Coolant, 5 Year/100,000 Mile Formula (glycol base coolant with corrosion inhibitors called HOAT) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water.

Note: Antifreeze mixture must always be at least 44%, all climates year round. Maximum protection (-90d) is provided with a 68% mixture protection.

MS5931 IS THE ONLY FLUID THAT CAN BE USED FOR THE POWER STEERING SYSTEM. NO EXCEPTIONS!

Important note:
The factory fill power steering fluid for all 1999-2004 Grand Cherokees is a unique fluid, MS5931. ATF+4 (MS9602) should not be mixed or used as a “topping off” fluid on the Grand Cherokee WJ. All WJ models should be serviced using ONLY the special MS5931 fluid. ATF+4 is NOT an approved Power Steering Fluid and should never be used under any circumstances. Note that all fluids will darken in color with usage and fluid color is no longer an indication of fluid condition.

(TECH NOTE: Never clean spark plugs on the 4.7L H.O. engine. Damage to the platinum rivet will result. Also, do not use a wire-type gapping tool for the same reason. Use a tapered-type gauge.)
