ENGINE
EXTENDED LIFE COOLANT (ELC) EXHIBITING NITRITE DEPLETION IN MACHINES EQUIPPED WITH ALUMINUM RADIATORS-NITRITES IN EXTENDED LIFE COOLANT (ELC) CAN REACT WITH THE ALUMINUM COOLER TO PRODUCE ELEVATED PH AND LOW NITRITE LEVELS IN SCHEDULE OIL SAMPLING (S@O@S) SAMPLES. AS THERE ARE MULTIPLE ISSUES THAT CAN CONTRIBUTE TO THE DEPLETION OF NITRITE, CONTACT YOUR LOCAL CAT DEALER TO REQUEST LEVEL 2 COOLANT ANALYSIS IF NITRITE DEPLETION IS EXPERIENCED.
ENGINE AND ENGINE COOLING:EXHAUST SYSTEM
THE EXISTING EXHAUST FLEX PIPE CAN CRACK ON CERTAIN CT660, CT680, AND CT681 ON-HIGHWAY TRUCKS. IF THE EXISTING EXHAUST FLEX PIPE CRACKS IT CAN/WILL RESULT IN AN EXHAUST LEAK AFTER THE AFTERTREATMENT SYSTEM BUT BEFORE THE VERTICAL STACK. REPLACE THE EXHAUST FLEX PIPE AND BOTH CAB SHOCKS.
STRUCTURE
AFTERTREATMENT OUTLET NOX SENSOR INTERNAL WATER SHIELD INSTALLATION - WATER INTRUSION CAN CAUSE THE MALFUNCTION OR FAILURE OF THE AFTERTREATMENT OUTLET NOX SENSOR ON VERTICAL EXHAUST CONFIGURATIONS. THE RECOMMENDED REPAIR IS TO INSTALL A RAIN SHIELD WHICH PREVENTS WATER FROM TRAVELING DOWN VERTICAL EXHAUSTS FROM CONTACTING THE OUTLET NOX SENSOR.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
