Things You'll Need:
- Catch can
- Screwdriver
- Pliers
- Knife
-
Step 1
Ensure the engine has cooled for an hour after driving and remove the radiator cap. Release the shroud over the coolant hoses by removing the four screws at the front of the shroud. Place a bucket or catch can under the radiator drain plug and remove enough fluid to minimize leaking when removing the hoses.
-
Step 2
Loosen the clamps with a nut driver or pliers. Slide the clamps off the fitting and let them hang on the hose. Pull and twist the hose until it is free of the nipple. If a hose is difficult to remove, cut it with a knife and peel the hose off the fitting.
-
Step 3
Dip the ends of the new hose in clean coolant and slide the clamps onto the hose. Push the hose onto the fittings. Turn the hose around if one end is difficult to get on the nipple.
-
Step 4
Verify the radiator drain plug is closed and fill the radiator with a 50/50 mix of coolant and water. Replace the radiator cap and start the Jeep Grand Cherokee. Look for leaks around the hose fittings and add coolant as needed when the radiator has circulated.
