🔌 Function

The heater raises engine coolant and block temperature before starting, reducing cranking load and improving early combustion.

⚠️ Common Signs of Failure

• Engine remains cold while the heater is energised
• No electrical current draw
• Circuit breaker or residual-current device tripping
• Coolant leakage around the heater
• Burnt connector or cable
• Corroded or open heating element

🛠️ Service Notes

• The cooling system must be filled and properly vented before the heater is switched on — energising the element in a dry or air-locked jacket will burn it out
• Isolate the shore supply and let the engine cool before removing or fitting a heater, and drain enough coolant to work below the heater opening
• Renew the sealing ring or gasket at the opening and tighten to the figure in the workshop manual for your engine
• Inspect the element for scale and the housing for corrosion; a heavily scaled element runs hot and will fail again
• Have the electrical connection made off correctly and protected, fed from a properly earthed and protected shore supply, and check the cable and connector for damage each season
