Fig. Fig. 5 Remove the pipe plug and drain the coolant into a suitable container


CAUTION
When draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Disconnect the negative (-) battery cable.
  2.  
  3. Raise the vehicle and support with jackstands.
  4.  
  5. Position a suitable drain pan under the radiator drain plug and drain the coolant into pan.
  6.  


CAUTION
Exercise extreme care when removing the cap from a hot radiator. Wait a few minutes until the engine has time to cool somewhat, then wrap a thick towel around the radiator cap and slowly turn it counterclockwise to the first stop. Step back and allow the pressure to release from the cooling system. Then, when the steam has stopped venting, press down on the cap, turn it one more stop counterclockwise and remove the cap.

  1. Remove the front wheel and tire assemblies.
  2.  
  3. Remove the radiator and engine hoses.
  4.  
  5. Remove the two bolts from the pipe bracket-to-crossmember.
  6.  


CAUTION
Lower the pipe slowly to prevent spilling coolant into your eyes because there may be coolant still in the pipe.

To install:

  1. position the pipe into the crossmember and torque the bolts to 7 ft. lbs. (10 Nm). Install the radiator and engine coolant hoses and tighten the clamps.
  2.
