Cummins Inc. said it has extended its uptime guarantee for all EPA-certified heavy-duty on-highway truck engines placed in service through Dec. 31, 2004.

"The Cummins Uptime Guarantee provides assurance to trucking fleets and owner-operators of the exceptional performance and reliability of these 2004 EPA-certified and compliant Cummins engines," said Tom Kieffer, Cummins executive director of marketing.
"Our customers confirm that these engines are proving their reliability on the road every day, and extending the Uptime Guarantee reinforces Cummins confidence in these products."
Cummins has manufactured and delivered more heavy-duty engines certified and compliant to the EPA emissions standard since October 2002 than any other engine manufacturer.
With more than 30,000 heavy-duty engines in service and more than a billion miles of real-world experience, the Cummins ISM and ISX engines are recognized as the most dependable products in the marketplace.
The Uptime Guarantee covers Cummins ISM and ISX engines for the first 12 months of operation. With the guarantee, Cummins will reimburse the customer for up to three days' truck rental for any failure on an ISM or ISX engine that cannot be repaired within 24 hours. The Cummins Uptime Guarantee was first introduced in August 2002.
Headquartered in Columbus, Ind., Cummins serves its customers through more than 500 company-owned and independent distributor locations in 131 countries and territories. For more information, visit www.cummins.com.
