- 1). Park your Jeep in an area that gives you room to work. The engine should be cool before you begin working.
- 2). Use the drainage valve on the passenger side of the radiator to drain the coolant out of the old radiator into a drainage bucket. A 2-gallon bucket should be large enough to handle the amount of coolant.
- 3). Remove the auxiliary electric fan and unbolt the mechanical fan shroud. They are located directly on top of the radiator and are held in place by bolts in the radiator cross section. Once those are removed, you can then unbolt the metal cover plate that is on top of the radiator and pull the cover off.
- 4). Unhook the upper and lower radiator hoses as well as the two transmission cooler lines if you have an automatic transmission. Take off the straps that connect the radiator to the air conditioning condenser. There should be no other hoses or connections to the radiator at this point. If there are, remove them. The hoses should come off with quick-connect fittings, or you can pull them off with pliers.
- 5). Pull out the radiator. Everything should be disconnected from it at this point, and it should be empty, so removing it should not be difficult.
- 1). Slide your new radiator into the space where the old one was and reconnect the hoses to it.
- 2). Reinstall the auxiliary electric fan and bolt the mechanical fan shroud back into place. Tighten the drain plug to make sure the new radiator is ready to hold coolant.
- 3). Pour new coolant into the radiator and look for any signs of leaking. Add water as well if your coolant requires it. Check the back of the jug and follow any instructions. If there are no leaks, turn on your engine and slowly pour more coolant into the radiator until it is full.
- 4). Screw the radiator cap back on and fill the coolant reservoir to the fill line. Check your levels over the next few hundred miles of driving and add more coolant as needed.
