Your Jeep Grand Cherokee may have an electric engine fan or a mechanical (belt-driven) engine fan. These steps apply to replacing the electric engine fan in a Jeep Grand Cherokee and should require nothing more than a wrench and a little time. If it becomes necessary to remove the upper radiator hose, you will also need a screwdriver and a clean, covered container for the engine coolant.
Disconnect and isolate the negative battery cable in your Jeep Grand Cherokee.
Unplug the fan's electrical connector. This step is just like unplugging any electrical appliance.
Use your wrench to remove the bolts from the upper fan shroud (the upper part of the fan's housing) and lift the fan shroud and fan assembly out of the engine compartment.
Insert the new fan assembly into the engine compartment. Slip the shroud into its retaining tabs and tighten the fan shroud bolts back into place until it is fully secure.
Reconnect the fan's electrical connector and the negative battery cable, in that order.
