The 42-year-old Liege-born driver’s last WTCC appearance came in 2006, when he drove a Lacetti in two rounds of the Championship in addition to winning the ADAC Procar Championship in Germany that year.
Radermecker is also the 2005 Belgian Touring Car champion and the runner-up in the 2002 French Supertouring Car Championship.
"I am really very happy of this opportunity to be back in the WTCC and behind the wheel of a Chevrolet, in ideal conditions and in my own country," said Radermecker.
"I am conscious that the level of professionalism and competitiveness in the series is tremendously high, but I hope that my excellent knowledge of the track will be a plus and I am confident that I can do well and help the Chevrolet team achieving a successful racing event in Belgium.”
Radermecker will participate in a test session with the team in the lead-up to the event to familiarise himself with the Chevrolet Cruze.
