Signs Your Engine Needs an Overhaul

When is it time to bring your engine in for an overhaul? The answer is there is no clear-cut answer. While engines with over 750,000 miles should get more attention, mileage is not the only indicator. Duty cycle, route variation, load capacity, and geography all factor into the need for an overhaul.

Listen to your engine. Learn the common signs of engine trouble so you’ll know when to seek the advice of a Cummins certified repair technician.
