INDIANAPOLIS (April 20, 2011)—Navistar International Corporation (NYSE:NAV) announced today that its expanding engine components business, PurePOWER Technologies LLC, will add jobs to the Indianapolis community. 

The company will recall 150 workers by June 2011 and plan to hire 100 additional workers by 2014 at the Indianapolis foundry, one of the few remaining facilities in the United States to make cylinder blocks and heads. The Indianapolis facility is capable to serve the needs of any manufacturer in the diesel engine arena.

“The Indianapolis foundry is a vital part of our efforts to maintain manufacturing capabilities and technical skills in the United States,” said Eric Tech, president, Navistar Engine Group. “As a result of our investment to make the Indianapolis foundry a state-of-the-art facility, we will make the company more competitive to meet the global demands of the diesel engine industry.”

Today’s announcement is part of the strategy to make PurePOWER Technologies a world-class supplier of engine components and is part of the effort by company officials to work with local community and labor leaders to create a more competitive structure. PurePOWER’s historic reinvestment in the foundry was celebrated at an event attended by community and labor leaders and employees.

“PurePOWER’s investment will revitalize this facility and symbolizes how cooperation among companies, labor leaders and community leaders can transform America’s manufacturing base for the future,” said Gary Canter, UAW 226 President.
