MaxxForce Series

Navistar’s MaxxForce series is used in International Class 6-8 DuraStar and WorkStar trucks. These diesel engines are well-know for their wet-sleeve design and now notorious for EGR (Exhaust Gas Recirculation) system issues.

However, the manufacturer took care of the defective EGR in a swift settlement with the owners, and the engines have since shown to be quite reliable. That said, MaxxForce engines are still rather expensive to maintain, especially at an authorized repair center where the labor rates tend to be quite on the higher side nowadays.

Fortunately, you can easily maintain your Navistar engine using a MaxxForce service manual and significantly reduce the related expenses. Even better, our digital repair manuals are the same used by professional Navistar and International technicians, and as such, contain every troubleshooting and repair procedure provided by the manufacturer, including step-by-step instructions, exploded-view illustrations, wiring diagrams, torque specs, etc. — no matter what you need to repair your MaxxForce engine, it’s in there!
