    4.3L Engine



    CAUTION

    Never open, service or drain the radiator or cooling system when
    hot; serious burns can occur from the steam and hot coolant. Also, 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 quantities. 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. Drain the engine cooling system.










      Fig. Place a suitable container beneath the radiator petcock and
      open the petcock to drain the coolant












      Fig. Exploded view of a common radiator and shroud assembly





    3. If equipped, remove the air inlet duct.


    4. Disconnect the overflow hose from the radiator, then disconnect
      the upper and lower radiator hoses.



    5. If equipped with A/C, it may be necessary to remove the A/C hose
      retaining clip and reposition the hose for shroud and/or radiator
      removal. DO NOT disconnect any refrigerant fittings.




      NOTE

      If equipped with a 1 piece shroud, then shroud may be unbolted
      from the radiator support and pushed back over the cooling fan instead
      of removing it completely.






    6. If equipped with a 2 piece radiator/fan shroud, remove the upper
      fan shroud-to-radiator support bolts and the upper fan shroud-to-lower
      fan shroud retainers. Remove the upper shroud from the vehicle.



    7. If equipped with an A/T, disconnect and plug the fluid cooler
      lines at the radiator. Plug all openings to prevent system contamination
      or excessive fluid loss.



    8. If equipped with a factory engine oil cooler which is integral to
      the radiator, disconnect and plug the oil cooler lines at the radiator.
      Plug all openings to prevent system contamination or excessive fluid
      loss. Plug all openings to prevent system contamination or excessive
      fluid loss.



    9. If equipped, remove the lower fan shroud.


    10. Lift the radiator straight upward from the supports and from the
      vehicle. Be careful to lift the radiator straight upward and not to tilt
      it excessively as the radiator will still contain a significant amount
      of coolant and, if applicable, transmission fluid/engine oil.











      Fig. Use pliers to remove the upper radiator hose clamp and then
      disconnect the hose from the radiator












      Fig. The air inlet duct assembly is retained by plastic pins.











      Fig. Remove the upper air duct assembly











      Fig. Remove the upper shroud bolts











      Fig. The upper shroud is attached to the lower shroud with bolts











      Fig. After unfastening the bolts, separate the upper shroud from
      the lower shroud












      Fig. The top of the lower shroud will have to be tilted inward to
      clear the cooling fan to remove the shroud












      Fig. The lower shroud clips into the bottom of the radiator











      Fig. Disconnect the lower hose from the radiator











      Fig. Remove the radiator from the engine compartment






    To install:




    1. Lower the radiator into position on the supports.


    2. If equipped, install the lower fan shroud.


    3. If equipped, remove the plugs, then connect the engine oil cooler
      lines and tighten the fittings.



    4. If equipped with an A/T, remove the plugs, then connect the
      transmission fluid cooler lines and tighten the fittings.



    5. Install the upper fan shroud and secure using the support and
      lower shroud retainers.



    6. If applicable, reposition the A/C refrigerant hose and secure
      using the retaining clip.



    7. Connect the overflow hose, upper and lower radiator hoses.


    8. If equipped, install the air inlet duct.


    9. Properly refill the engine cooling system.

    Hope helps with this.

Cooling transmision lines


Make sure that you use thee correct tools when removing the hose. Important to keep in mind that these lines seize up so you may need to heat the fittings.
When installing new line, good idea to use a little anti-seize and then top off transmission fluid with vehicle running and it has reached operating temperature.

I need to know how to change the transmission fluid in my 1998 bravada


There are a few mays to do this, you could take it to the transmission shop and have them service it or you can do it your self. If you want to replace the transmission fluid and filter you have to drop the transmission oil pan, your going to have to remove the oil pan bolts and shifter linkage to the 4X4 and once the pan is off. Just pull off the oil filter from the valve body and replace the O ring with  the new O rings to ensure the new filter will not fall off from the valve body and then re-install the everything in revers. Once the pan is back on refill the transmission with AFT and test drive. The other way you can drain the system with out the filter replacement is to disconnect the transmission line at the radiator on the passenger side, top by the radiator cap. Connect a hose to the line to a large bucket and start the engine, the fluid will drain fast so be ready to turn the engine off so you don't burn out the front pump. you can also judge how much fluid is in the transmission by the amount of fluid is collected in the bucket. Note: make sure you have a large bucket. Once you think you have drained enough transmission fluid, turn the engine off and re-install the transmission line to the radiator and refill the transmission with AFT.
