Themba Zwane needed just eight minutes to score what proved to be the winner for Sundowns, with Al-Hilal unable to stage a comeback.
Sundowns top Group A with three points, with the other group match between reigning champions Ahly of Egypt and Al-Hilal's Sudanese rivals Merreikh postponed due to the former's participation in the FIFA Club World Cup.
In Group C, Etoile settled for a goalless draw at home to CR Belouizdad and they were also lucky to escape a defeat.
CR Belouizdad's Kheireddine Merzougui wasted a penalty at the death, to the relief of Etoile.
Tunisian side Esperance meet Botswana's Galaxy in the other group match on Saturday.
