Teen sensation Raducanu made history when she became the first qualifier to win a grand slam title at Flushing Meadows last month.
The 18-year-old split from coach Andrew Richardson following her stunning triumph in New York, revealing she wants to work with someone who has greater WTA Tour experience.
Raducanu will work with Jeremy Bates, the Lawn Tennis Association's national coach, when she plays her first tournament as a major champion at the Indian Wells Open in California.
The Brit, who will face Maria Camila Osorio Serrano or Aliaksandra Sasnovich first up after being given a bye into the second round, will take her time to mull over who will be her permanent coach.
She said in a press conference on Tuesday: "Jeremy is part of women's tennis at the LTA so while he's here he's helping me out.
"But going forwards I'm just going to wait and find the right person, I'm not going to rush into anything. I want to make sure I make the right decision.
"Even though I'm quite young I've got a lot of experience banked and at the end of the day you're out there on your own and you have to be your own coach on the court, so I'm pretty comfortable."
Raducanu is relishing being back in action after a whirlwind few weeks off the court following her US Open heroics.
"I'm very excited to be here," Raducanu added.
"It's my first time playing in Indian Wells, and it's a beautiful place. I just can't wait to get started. I love the facilities, everything is just so nice to be around.
"I don't really want to change anything. What got me to this point is not thinking anything differently so if I put additional thoughts in my head then that will just create a problem I think. I'm just going to keep going about my business and staying the same.
"It's been a very cool three weeks. I got to experience some great things that I probably never would have got to do before but after that I just went straight back to training and focusing on this competition and the upcoming ones that I've got lined up."
