## NHTSA's summary

MITSUBISHI: WATER PUMP LEAK INSPECTION CRITERIA. WHEN EXAMINING A VEHICLE FOR COOLANT LOSS, A COMPLETE COOLING SYSTEM DIAGNOSIS IS REQUIRED. THE PRESENCE OF DRIED COOLANT RESIDUE IS NOT AN INDICATION OF A DEFECTIVE WATER PUMP. WATER PUMP CLEARANCES VARY WITH ENGINE TEMPERATURE AND NEW WATER PUMPS CAN LEAK COOLANT DUE TO THE PRESENCE OF MANUFACTURING RESIDUE \(E.G. CASTING SAND\), WHICH IS FLUSHED FROM THE PUMP OVER TIME. AFFECTS ALL MODELS AND MODEL YEARS. \*PE
