🔌 Function

Transfers heat from the engine's closed coolant circuit into raw water drawn from outside the boat, keeping the engine at temperature without putting seawater through the block.

⚠️ Common Signs of Failure

• Coolant temperature climbing under load, then settling at idle
• Coolant loss with no external leak, or oil film in the header
• Raw water flow dropping at the outlet
• Tube stack found blocked with scale, silt or shed impeller debris
• Weeping or staining at an end cover joint

🛠️ Service Notes

• Renew the end cover seals and check the sacrificial anode when fitting
• Look for shed impeller vanes upstream, as debris from a failed pump is a common cause of blockage
• End cover 3884169 and hose 3884397 are listed against the same engines and are worth checking at the same time
