AFTERCOOLER HOSE 90

This is a 90-degree molded elbow hose (part number 3934720) used in the aftercooler system of Cummins ISB and QSB diesel engines. It carries coolant between the aftercooler and other components to help cool the air coming from the turbocharger. Over time, the hose can crack or develop leaks, so replacement is common during coolant system maintenance or when leaks are spotted. This is a genuine Cummins part that ensures proper fit and durability.
