Isuzu Commercial Truck of America has set up a network of service centers staffed with technicians specially trained to service the Isuzu 4H and 6H diesel engines in Isuzu, GMC and Chevrolet medium-duty trucks.

With over 500 locations nationwide, the Isuzu Engine Certified Service Centers offer “state of the art” diagnostic equipment and genuine Isuzu parts, as well as technicians who have received training in diagnostics, troubleshooting, repair, routine maintenance and warranty work for the Isuzu diesels, says the company.

To minimize downtime, the service centers will have the ability to place orders 24/7 for any parts not in inventory and have them shipped directly from a master parts depot.

The Isuzu 4H engine powers the Isuzu N-Series and GMC/Chevrolet W-Series; the 6H powers the Isuzu F- and H-Series, the Chevrolet Kodiak/GMC TopKick and the GMC/Chevrolet T-Series.
