## Discrepancy

DURING CRUISE FROM RJTY TO FJDG WHILE CLIMBING FROM FL340 TO FL360 ALL FOUR MANIFOLD TEMP LIGHTS ILLUMINATED CAUSING THE LEFT AND RIGHT MANIFOLDS TO OVERTEMP.  THE CREW DIVERTED TO RODN AND LANDED SUCCESSFULLY.  MAINTENANCE REPLACED THE NUMBER 2 AND NUMBER 3 PRE-COOLER CONTROL VALVES.  THE OPERATIONAL CHECK WAS GOOD ON THE GROUND AND THE AIRCRAFT WAS RETURNED TO SERVICE.
