Pohlman will serve in the role for the interim. He has been in numerous positions with the racing organization since 2006.
“We are pleased to have someone of Jim’s caliber to be able to place into this role on the No.42 team,” team owner Chip Ganassi said in a statement. “Jim has been with us a number of years, and I have confidence in his abilities to move the team forward.”
Pattie had served as Montoya’s crew chief since the middle of the 2008 season. He guided Montoya to a victory in 2010 at Watkins Glen, NY. They recorded 39 top-10 finishes in 111 starts together and made the Chase for the Sprint Cup championship in 2009, finishing eighth in points.
Montoya is currently 17th in the point standings, as he trails 10th-place drivers Denny Hamlin and Tony Stewart by 59 points.
This was the second crew chief change announced in the series this week. On Monday, Richard Petty Motorsports revealed that Greg Erwin replaced Mike Shiplett as A.J. Allmendinger’s crew chief.
