Iirc, the OTL Argentina during WW2 period is actually a well developed nation. The Argentine Navy main force in WW2 would be two dreadnought battleships built by USA, 5 armored cruisers built by Italy, 3 modern light cruisers and 14 destroyers and 22 torpedo boats built by the British as well as a small number of locally built coastal defense ships and minesweepers.

The Battleships ARA Rivadavia and the Armored Cruiser ARA Garibaldi
Although Argentina might not fighting alone as it just gained Brazil as its new satellite state so the combined strength of Chile, Argentina and Brazil will definitely caused the Mexicans some headaches.
The Argentine-Brazil and Chile combined fleet would have 6 battleships in total to give them more chance fighting the Mexican Gulf Fleet, however the only the Rivadavia, Moreno and Almirante Latorre are on par with the Mexican ships as they are proper super dreadnoughts whereas Brazillian Minas Geraes class were wholefully outdated by this period and the Rio de Jainero is simply lacking both armor and firepower to be able to effectively countering the Mexican Monasterio class fast battleships with 380mm guns.
