The fun film stars the three Deols - Dharmendra and his two sons Sunny and Bobby.
"I think we will make the third part. I hope people like the series," the 77-year said Thursday at the theatrical launch of the film.
Samir Karnik-directed "Yamla Pagla Deewana" came in 2011 and did brisk business at the box office, which inspired the Deols to go for part two.
Dharmendra says sequels have "become the norm of the industry today".
"People like a film, it becomes a brand and they accept it," he added.
Part two has been directed by Sangeeth Sivan and Dharmendra said: "We have made a good film. When you will watch it, you will feel that it is better than the first one."
However, he clarified that it is not a continuation of the original.
"Only my character and Sunny and Bobby's character are the same, everything else is new," he said.
"Yamal Pagla Deewana 2" is all set to release June 7.
