How to Replace a Jeep Radiator Hoseby Leonardo R. Grabkowski
Radiator hoses are exposed to extreme temperatures in your engine bay. Over time, they may deteriorate and develop leaks. Leaking radiator hoses will require replacement. Replacing radiator hoses in Jeep vehicles will be basically the same for all models, including the Wrangler and Grand Cherokee. While the process of swapping out the hose is quite simple, one must take certain precautions when working with engine coolant systems.
Park your Jeep in a suitable workplace, free of distraction. Because you will have to drain the engine coolant, it is best to perform the job on a flat surface. Concrete or asphalt is preferred. Make sure the engine is cold. If recently driven, let the engine cool off for 30 minutes.
Identify the specific radiator hose that needs to be replaced and purchase a replacement, if you have not done so already.
Disconnect the negative battery cable. Place the drain pan underneath the radiator. Remove the radiator drain plug to drain the system. Some models are equipped with a brush guard underneath underneath the front part of the engine bay. If equipped, remove this prior to accessing the drain plug.
Let the engine coolant completely drain into the pan. The process will usually take 20 to 30 minutes. Cover the engine coolant and keep the coolant in a safe location. Engine coolant is extremely toxic and its sweet smell attracts animals.
Remove the clamp(s) mounting the specific radiator hose to the radiator and engine components. Most clamps have a screw-mounted clip to keep them tight. Remove the screw and disconnect the radiator hose. Remove the hose from the radiator and carry it in a "U" position to prevent coolant spillage. Drain any leftover coolant into the drain pan.
Attach the new radiator hose and secure it with the existing clamps. Reattach the coolant drain plug and replace the engine coolant. Reconnect the negative battery cable and start the engine to check for leaks.
- check Check your engine coolant after you drain it. If the coolant is contaminated, replace it with new coolant. Check your owner's manual for exact coolant specifications. Check with your local waste authority for disposing of the old coolant.
