Service councilor 26 is listing for '52, not '50.

SC 26#6 shows the second version cooler for the 23rd series. First version cooler upon Ultramatic introduction in the 23rd series models was in the radiator bottom tank but it proved problematic when leaks and other issues developed. Materials to fix or replace that one were apparently hard to come by during the Korean war so they came up with the second version which was the external frame mounted water cooler shown in the article. Water for that cooler was provided from the outlets used for heater hoses. Materials in the form of a new radiator bottom tank finally became more available to replace the tank version but believe the external cooler became standard for the remainder of the 23 series production. It might have been changed a bit or possibly an aftermarket version was developed because the cooler Joe shows in his post is a bit different from the one in the SC article. The updated final cooler design used until the end came along in 51 with the water cooler mounted on the engine with water supply via the bottom radiator hose..
