🔌 Function

Takes heat out of the fuel returning from the injection system before it goes back to the tank, keeping fuel temperature within the range the injection equipment needs.

⚠️ Common Signs of Failure

• Power falling away after a period at full load as fuel temperature rises
• High fuel temperature warning or a stored fault
• Diesel smell in the engine space, or a rainbow film on the bilge water
• Coolant loss or fuel found in the coolant, showing an internal leak
• Core externally corroded, weeping or blocked with debris on removal

🛠️ Service Notes
