🔌 Function

Hot engine coolant flows through one side of the exchanger while seawater flows through the core on the other side. Heat passes through the metal tubes into the seawater, which is then discharged through the exhaust system.

⚠️ Common Signs of Failure

• Engine overheats despite serviceable coolant and seawater pumps
• Coolant or seawater leaks from the casing or end covers
• Internal corrosion or scale restricts exchanger tubes
• Coolant level rises, falls or becomes contaminated through an internal leak
• End-cover gaskets, core seals or pressure cap fail to hold pressure
