                              INTERNATIONAL'S HEAVY TRUCK PLANT TO REMAIN IN CHATHAM

  Participation By Government of Canada and Province of Ontario, Coupled With New CAW Contract Key To Preserving
                                                  Jobs In Canada

         WARRENVILLE, Ill. --  September 4, 2003 -- International Truck and Engine Corporation will keep its
Chatham, Ontario plant open and maintain a production schedule of heavy trucks, as the result of a long-term
investment by the company, Government of Canada and the Province of Ontario, it was announced today.
         The government participation is part of the company's 10-year, $189 (CDN$270) million program that
includes investments in technology, advanced skills training, and state-of-the-art equipment to modernize and
update the plant. Major elements include two new research and development centers to be established in
partnership with one or more Ontario universities.
         The Government of Canada will contribute up to $23 (CDN$33) million under its Technology Partnerships
Canada program and various training programs. The Province of Ontario will contribute up to $22 (CDN$32) million
towards the total investment as part of its  $438 (CDN$625) million Large Scale Strategic Investment Initiative
announced in February 2003.
         As previously reported, the Canadian Auto Workers union (CAW) is also making a major investment in the
future of the Chatham plant and its workforce. In May, the company and the CAW reached an agreement on an amended
contract that runs through January 31, 2007 that will provide $31(CDN $44) million in annual cost savings. The
contract can be extended for an additional two years by mutual agreement.

         Dan Ustian, president and chief executive officer of Navistar International Corporation, said the
decision to keep the Chatham plant open, bolstered by the new CAW contract and the government financial
participation, "reinforces our commitment to the heavy truck segment of the business and our goal of overall
leadership in the North American truck market."
         "The modernized International plant will help contribute to a sound economic future for Chatham-Kent and
continued employment for 750 workers with a strong potential for growth," Ustian said.
         Efforts to achieve necessary cost reductions at Chatham began in December 2001. Unable to achieve
necessary cost savings, International announced plans to close its Chatham plant on October 17, 2002, and a July
18, 2003 closing date was set on March 28. The closing date was extended while the company continued discussions
with government agencies concerning financial participation in programs to keep the plant open..
         Ustian said the financial participation coming from the Government of Canada and the Province of Ontario
in the areas of advanced research is particularly important. Truck research will focus on the development and
testing of advanced production technologies, while diesel engine research will center on reducing emissions to
meet more stringent emissions targets.

         NAVISTAR SAYS CHATHAM DECISION AND UAW WINDOW PROGRAM WILL NOT CHANGE COMPANY'S EARNINGS GUIDANCE

         WARRENVILLE, Ill. -September 4 -As reported earlier today, International Truck and Engine Corporation,
the operating company of Navistar International Corporation (NYSE:NAV), announced that it would keep its Chatham,
Ontario heavy truck assembly plant open.
         Daniel C. Ustian, Navistar president and chief executive officer, said the company is pleased to have
come up with a plan that meets the combined objectives of improved profitability for our heavy truck business and
continued operations in Chatham.
         Ustian noted that the impact of the decision to keep the plant operating would result in an adjustment
to the company's existing restructuring charge recorded in the fourth quarter of 2002.
         He added that the company has also accelerated the sign-up period for an early retirement window program
offered to certain eligible, long-service United Auto Workers union (UAW) represented employees.  The purpose of
the window program is to enable the company to address the changing staffing needs of the business. The expected
dates for retirement under the program have not been changed, but the earlier sign-up period requires the company
to account for the program in the fourth quarter of 2003.
         According to Ustian, Navistar is in the process of quantifying the impact of these decisions and will
disclose them with the release of its fourth quarter earnings.  Neither of these decisions however is expected to
impact the company's earning guidance issued in the third quarter earnings release on August 15, 2003.
         "These actions allow us to substantially complete our initial transformation strategy that we began in
1997," said Robert C. Lannert, vice chairman and chief financial officer.
