Re: 50 years ago I was given this USAF 54 3100
Most of the parts are here so got started. Drained radiator, Pulled old hose, thermostat and housing. 40+ year old upper Hose was so soft it tore in process. While hose was out moved fan up to radiator top from middle – At least 6”. Seems the new Radiator zip tie mounting kit was missing from box so Made do with parts from old kit. Just drilled holes on old front and rear pads and used regular zip ties to hold them in place. Cut head off new ties to lock them in place. Used 1” section of waste tie thru the inside recycled retaining pad as a safety measure against pull thru. Using a large zip tie to hang fan down from filler neck worked great to hold fan in position while installing ties. Later cut and removed it,
Replaced thermostat with the 180F and drilled a couple 1/16” 'burp” holes as many recommended. Old thermostat was leaking and was installed with only an O ring – no gasket or sealer. New Housing came with just a gasket. Used blue RTV on surfaces just in case. New 22” x 1.5” hose fit fine but forgot the replacement Radiator I installed over 23 years ago had a 1.25 neck, Cut a 2” section from a spare 1 ¼ hose and used it as a sleeve inside the new 1 ½ hose. Fastened both ends with Dual Stainless bands (installed in opposite directions).
Will have to wait a week until things calm down here to refill radiator and test results,
