Ricciardo made the surprise move from Red Bull to Renault at the end of last season.
The Australian wants to challenge for the F1 Drivers’ Championship and believes his new outfit will develop into a leading side over the coming years.
Team-mate Hulkenberg, who finished seventh in the standings in 2018, is hoping the extra knowledge hands his side the advantage.
“(Ricciardo’s) going to bring a breath of fresh air, and he’ll certainly have some important information coming from Red Bull,” the German told AMUS.
“Some things like how to adjust the car for example. I think it will be interesting for us.
“We drivers are not technicians and certainly not aerodynamicists so he can not say ‘we must do like this or that’.
“Unfortunately, it does not work that way.
“But he could help us by explaining what Red Bull did when setting up the car or what systems they have on their car.”
Meanwhile, Max Verstappen issued a parting shot to his old ally ahead of the new campaign.
“Personally I won’t miss him but he was fun and pleasant to have as a team-mate,” Verstappen told Dutch newspaper Algemeen Dagblad.
“That doesn’t happen often and perhaps it won’t happen again. But will I miss him? I believe Daniel will miss what he had here.”
Verstappen also spoke about how glad he is that Red Bull have ditched their Renault engines in favour of Honda from this year.
“Honda’s whole attitude and the plans they have, it’s totally different compared to what we were used to with Renault,” he added.
“With Renault we always had to push. It always had to come from us and it was usually ignored. Now it is the other way around and we are pushed to supply parts.
“They need gearboxes and things like that from us, which are really not that easy to make. But Honda just wants to test, test, test. They do more kilometres than I do on the circuit.”
