QuestionHi,
Can you tell me if the radiator can be removed separate from the AC condenser or does it have to be removed as an assembly. I am reading the jeep manual and it does not say anything about the AC condenser when removing the radiator. However after disconnecting all the lines, hoses, fan and mount bolts, it seems that the radiator is somehow attached to the condenser. I really can use your help. I do not what to disconnect the AC lines.
AnswerRADIATOR
REMOVAL
WARNING: DO NOT REMOVE THE CYLINDER BLOCK DRAIN PLUGS OR LOOSEN THE RADIATOR DRAINCOCK WITH THE SYSTEM HOT AND UNDER PRESSURE. SERIOUS BURNS FROM COOLANT CAN OCCUR. REFER TO COOLING SYSTEM DRAINING IN THIS GROUP.
Do not waste reusable coolant. If the solution is clean, drain the coolant into a clean container for reuse.
WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094) Hose Clamp Tool - Typical SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.
CAUTION: A number or letter is stamped into the tongue of constant tension clamps Clamp Number/Letter Location - Typical If replacement is necessary, use only an original equipment clamp with matching number or letter.
CAUTION: When removing the radiator or A/C condenser for any reason, note the location of all radiator-to-body and radiator-to-A/C condenser rubber air seals Air Seals - Typical These are used at the top, bottom and sides of the radiator and A/C condenser. To prevent overheating, these seals must be installed to their original positions.

Drain coolant from radiator. Refer to Draining Cooling System in this section
NOTE: The 4.0L engine does not require special tool 6958 spanner wrench or 8346 adapters to remove the fan drive from the water pump.
The thermal viscous fan drive is attached (threaded) to the water pump hub shaft. Remove fan/viscous fan drive assembly from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. Using spanner wrench 6958 with adapters 8346 (4.7L engines only) and a 36 MM Fan Wrench Viscous Fan Drive 4.7L Engine loosen the fan drive/ fan blade. Drive belt removal is not necessary for removal of fan drive.
Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
Remove the front grill. Refer to Group 23 for procedure.
Remove two radiator mounting bolts Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Disconnect both transmission cooler lines from radiator.
Disconnect electric fan connector, then disconnect connector harness from shroud (all 4.7L engines and heavy cooling package 4.0L only) Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Disconnect the radiator upper and lower hoses Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Disconnect the overflow hose from radiator Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Remove the air inlet duct at the grill.
The lower part of radiator is equipped with two alignment dowel pins Radiator Alignment Dowels They are located on the bottom of radiator tank and fit into rubber grommets. These rubber grommets are pressed into the radiator lower crossmember.
WARNING: THE AIR CONDITIONING SYSTEM (IF EQUIPPED) IS UNDER A CONSTANT PRESSURE EVEN WITH THE ENGINE OFF. REFER TO REFRIGERANT WARNINGS IN GROUP 24, HEATING AND AIR CONDITIONING BEFORE HANDLING ANY AIR CONDITIONING COMPONENT.
If equipped with an auxiliary automatic transmission oil cooler, use caution when removing radiator. The oil cooler lines are routed through a rubber air seal on the right side of radiator. Do not cut or tear this seal.
Gently lift up and remove radiator from vehicle. Be careful not to scrape the radiator fins against any other component. Also be careful not to disturb the air conditioning condenser (if equipped) Radiator, Shroud and Electric Fan - 4.7L Engine
INSTALLATION
CAUTION: Before installing the radiator or A/C condenser, be sure the radiator-to-body and radiator-to-A/C condenser rubber air seals Air Seals - Typical are properly fastened to their original positions. These are used at the top, bottom and sides of the radiator and A/C condenser. To prevent overheating, these seals must be installed to their original positions.
Equipped with air conditioning: Gently lower the radiator into the vehicle. Guide the two radiator alignment dowels through the holes in the rubber air seals first and then through the A/C support brackets Radiator Alignment Dowels Continue to guide the alignment dowels into the rubber grommets located in lower radiator crossmember. The holes in the L-shaped brackets (located on bottom of A/C condenser) must be positioned between bottom of rubber air seals and top of rubber grommets.
Connect the radiator upper and lower hoses and hose clamps to radiator Radiator, Shroud and Electric Fan - 4.7L Engine
CAUTION: The tangs on the hose clamps must be positioned straight down.
Install coolant reserve/overflow tank hose at radiator Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Connect both transmission cooler lines at the radiator Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Install both radiator mounting bolts Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Install air inlet duct at grill.
Attach electric fan harness to shroud, then connect harness to connector (all 4.7L engines and heavy cooling 4.0L only) Radiator, Shroud and Electric Fan - 4.7L Engine Radiator, Shroud and Electric Fan - 4.0L Engine
Install the grill. Refer to group 23, Body.
Install the fan/viscous fan drive assembly to the water pump.
Rotate the fan blades (by hand) and check for interference at fan shroud.
Be sure of at least 25 mm (1.0 inch) between tips of fan blades and fan shroud.
Fill cooling system.
Connect battery cable at battery.
Start and warm engine. Check for leaks.
