2010 3500 Change coolant, HOAT or OAT

[rosebunch]

I need to change my coolant, My truck came with HOAT but when is search for coolant, most are OAT formula. Do I need to be concerned to only use HOAT formula? I am sure this has been discussed before but I havn't been on the forum for a long time and I did not find any info on this.....
