As part of the deal, Mario Booysen will join Ajax.
The 20-year=old finally got his wish to leave the Urban Warriors after his failed move to Scottish champions fell through.
The move fell through after it was established that the defender had a problem with his foot.
Coetzee is set undergo surgery that would see him spend up to four months on the sidelines meaning he could make his debut for Sundowns in January next year.
