Troubleshooting
2Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| A high coolant temperature alarm condition | The primary cause of the overheat must be determined and the cause corrected to prevent a recurring overheat event. | 1) The coolant should be drained (after de-energizing the coolant heater) 2) Replace the engine thermostat(s) 3) Remove the engine water pump and inspect the impeller and seal for damage, replace as necessary. Reassemble and refill coolant according to the Installation and Operations Instruction Manual. 4) Run the engine to verify normal operating temperature. |
| Cavitation | Cavitation is a condition that occurs when bubbles form in the coolant flow in the low pressure areas of the cooling system and implode as they pass to the higher pressure areas of the system. This can result in damage to cooling system components, particularly the water pump impeller and cylinder liners. |
