Print

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2.  
  3. Drain the cooling system.
  4.  
  5. Remove or disconnect the following:

    Negative battery cable
     
    Coolant reservoir tank and bracket
     
    Upper mounting bracket
     
    Upper radiator hose
     
    Oil cooler lines, if equipped
     
    Lower radiator hose
     
    Cooling fan and condenser fan
     
    Fan motors and shields
     
    Radiator
     

  6.  

To install:

  1. Install or connect the following:

    Radiator
     
    Fan motors and shields
     
    Cooling and condenser fans and torque the bolts to 44 inch lbs. (5 Nm)
     
    Lower radiator hose
     
    Oil cooler lines, if equipped
     
    Upper radiator hose
     
    Upper mounting bracket
     
    Coolant reservoir tank and bracket and torque the bolt to 44 inch lbs. (5 Nm)
     
    Negative battery cable
     

  2.  
  3. Fill the cooling system to the proper level.
  4.  
  5. Start the vehicle, check for leaks and repair if necessary.
  6.  


WARNING
Do not remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

  1. Before servicing the vehicle, refer to the Precautions section.

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Drain the cooling system.
  4.  
  5. Remove or disconnect the following:
    CAUTION
    Do not damage or scratch the A/C condenser and radiator core while removing.


    CAUTION
    Because A/C condenser is onto the front-lower portion of radiator, moving to rear direction should be at minimum.



    Negative battery cable
     
    Engine cover
     
    Air duct and air cleaner case assembly
     
    Bracket mounting bolt for anchoring A/C piping
     
    Reservoir tank and bracket
     
    Upper and lower radiator hoses
     
    Radiator cooling fan assembly
     
    On A/T models, A/T fluid cooler hoses. Plug hoses to avoid leakage
     
    Cover, then two A/C condensing mounting bolts located in the upper part of the radiator
     
    Rotate two radiator upper mount brackets 90 degrees in the direction shown in the illustration and remove

  6.  
  7. Remove the radiator by performing the following:
    CAUTION
    Lifting A/C condenser should be minimum to prevent a load to A/C piping.



    With lifting and pulling radiator in a rear direction, disassemble lower mount from radiator core support center.
     
    Lift A/C condenser up and remove radiator after disengaging the fitting as front-bottom surface.
     



    After removing radiator, put A/C condenser on radiator core support center to prevent a load to A/C piping, and temporarily fix it with rope or similar means.
     

  8.  

To install:

  1. To install, reverse removal procedure.
  2.  
  3. Check radiator cap for any leaks.
  4.  
  5. Start and warm up engine. Check for engine coolant leaks and A/T fluid leaks.
