The 1999 Jeep Grand Cherokee has an engine driven clutch fan and an electric fan for the air conditioning condenser. Some of these vehicles have a separate transmission cooler, which is an option included in the towing package. This cooler is located in front of the radiator. Those vehicles without the towing package have a transmission cooler as an integral part of the radiator.

Step 1

Remove all the screws in the front grill, using the Phillips screwdriver. Place the drain hose on the petcock and into the drain pan. Use the pliers to open the petcock and allow the antifreeze to drain into the pan. Open the radiator cap to hasten the draining process. Remove the upper and lower radiator hoses, using pliers to squeeze the clamps to remove them.

Step 2

Disconnect the electrical connector at the auxiliary cooling fan. Remove the four nuts securing the clutch fan to the water pump pulley, using a wrench. Remove the four bolts securing the engine cooling shroud to the radiator shroud, using the appropriate socket.

Step 3

Lift the engine fan shroud and the engine fan out of the vehicle. Remove the four bolts securing the electric fan and shroud to the radiator, using the appropriate socket. Lift the electric fan out of the engine compartment.

Step 4

Remove the four bolts that secure the radiator cross member to each fender, using the appropriate size socket. Lift the cross member off the radiator.

Step 5

Detach both transmission cooler lines, using the special quick disconnect tool. Rock the radiator slightly rearward toward the engine and remove the air conditioning condenser-to-radiator bracket by removing all four bolts, using the appropriate size socket. Lift the radiator out of the engine compartment. Replace the radiator in the reverse of removal and fill with antifreeze and water.
