Fred, b4 pulling the radiator I'd check ALL the hose connections, also the timing/etc........if all are o/k then as far as pulling the radiator goes , you have the same setup as I had /have with my Oz 1940 Dodge(Plymouth based, see pic).......undo the upper & lower radiator hoses, then take the hood off, you should be able to undo the radiator and remove it and still leave the radiator surround there(its what the fenders etc bolt onto).......depending on the fan clearance, the fan may need to be unbolted from the water pump the the radiator removed.......there is no need to remove the water pump unless it is the cause of the overheating.......btw all this assumes that the radiator IS THE CAUSE of the overheating........why not take the car to a radiator shop and get them to do a pressure test?...........or is there obvious leaks etc from the radiator?........AND you don't need to even think about the water tube unless and until you have boiled/cleaned out the cooling system and it still overheats, personally I think you have either a timing or radiator problem...... andyd
