Natural Gas Engine Warranty Information

Customers with Cummins power, whether they spec a diesel or natural gas engine, get the same expert service, support and coverage. Cummins Westport base warranty coverage for the ISL G natural gas engine is the same as for the diesel counterpart.

The truck engine base warranty covers 100 percent parts and labor and any progressive damage for 2 years or 250,000 miles (402,336 km) on any warrantable failure, which is defined as one due to defects in Cummins material or factory workmanship.

Extended warranty coverage up to 5 years and 300,000 miles (482,803 km) for the ISL G. Contact your Cummins representative for more information.

As with any Cummins engine, vehicle operators can have their Cummins Westport natural gas engine serviced at authorized Cummins service facilities throughout North America. These engines share many of the same components – including diagnostic software capabilities – as Cummins diesel engines. Cummins technicians are fully trained to handle natural gas engines, and have access to our extensive parts network.

That’s not all. No matter where they are, your customers with Cummins Westport natural gas engines can get help with locating an authorized and available service facility in the United States or Canada by calling Cummins Care at 1-800-DIESELS™ (1-800-343-7357).
