You didn't give any info on your Magnum tractor.....but, CNH had a SCA coolant called XHD that was purple. Now, with the new oil rebranding, it is called IAT (Inorganic Acid) and it is blue. That's what was used in most of the Cummins based tractors.
The newer t4 magnums had OAT coolant, which used to be yellow and now the equivalent formulation is pink.
