Verify the customer concern by operating the system. 1. 2. Visually inspect for obvious signs of mechanical damage or electrical damage. If the concern cannot be reproduced, carry out a road test and/or visual check with the aid of the following table. Visual Inspection Chart Mechanical Coolant leaks Oil leaks Leaks in the fuel system Visibly damaged or worn parts Loose or missing nuts or bolts 2. 3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. 3. 4. If the concern is not visually evident, verify the symptom and refer to the Symptom Chart. 4. Symptom Chart Symptom Chart Symptom Possible Sources Action Difficult to start during hot or cold start Piston ring(s) worn, damaged, sticking or worn piston/cylinder. INSTALL a new engine.
