        Harry, OK, here ya go >  This is how I do it here in my shop.  No need to remove the push rod tube tins or those allen headed bolts in the heads.  Remove the lower rad hose in the front and collect the fluid that comes out.  Attach another old lower rad hose that you will modify to have a T fitting in it leading to a long hose with a shut off valve at the end.  Put this hose into a container large enough to collect all the rest of the fluid.  Open both heater valves to MAX.  In the engine compartment, open the bleeder on the thermostat housing.  Attach an old cap to the main coolant tank that has had the pressure relieve valve drilled out.  Attach a compressed air line that has been shut off to that cap.  Slowly turn on the air pressure until all the fluid has been purged from the system.  Run the engine briefly during this purge to get the water pump to expel any fluid in the engine.  When your about sure all the fluid had been purged, remove the air line and attach a water hose to that cap.  Remove the drain hose from your fluid collection container and place it in a convent drain then run fresh water through the system for 10 ~ 15 minutes, running the engine briefly during this period.  Now remove the water hose and reattach the air line and blow out all of the water.  Replace the lower rad hose with the proper one, then fill and bleed the system with new coolant.
