According to the 2000 Ford Explorer Owner Guide :
( Motorcraft MERCON automatic Transmission Fluid is used as the power
steering fluid )
Regular power steering fluid.
I don't think there is any more than one kind of power steering fluid. I've only ever seen one.
1.2 liters
DOT ( 3 ) brake fluid is used for the hydraulic clutch and the brakes in a 1997 Ford Explorer Sport
That's the accessory drive belt at the front of the engine for your power steering , air conditioning compressor , alternator etc.
Try under the steering wheel
If this is the 4.0 L - OHV engine , it's on the drivers side of the engine below the power steering pump
To change the rack and pinion on a 1997 Pontiac Trans Sport, first, safely lift the vehicle and remove the front wheels. Disconnect the steering shaft from the rack, then drain the power steering fluid. Remove the mounting bolts for the rack and pinion, disconnect the tie rod ends, and carefully take out the old unit. Install the new rack by reversing the process, ensuring all connections are secure, and refill the power steering fluid before testing the steering.

This is all I can find. I would think your Warngler is the same but it may not be. Do not use ATF fluid. You can purchase a generic fluid as long as it meets the Mopar specs. Mopar®P/N 04883077 Hydraulic fluid / Power steering fluid (MS5931)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. Read your owner's manual, look on the fill cap, or call your local Jeep dealer to be sure.
On a 1991 Ford Explorer , 4.0 litre , OHV , V6 engine : I believe the oil pressure sending unit is on the drivers side of the engine , below the power steering pump
behind dash drivers side mounted on steering column
