# 21105280 Engine Heater | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine Volvo Penta 220-240 volt, 1500 watt coolant engine heater for TAD13 industrial engines. Installed in the engine coolant circuit, the heater warms the block and coolant before starting, improving cold-start reliability and reducing white smoke, battery load and initial engine wear. The heater is used in compressor-equipped installations with model-specific coolant pipes and electrical extension cables.

## 🔌 Function

Converts mains electrical power into heat within the coolant circuit, warming the engine block before starting.

## ⚠️ Common Signs of Failure

-   Heater draws no current or remains cold when energised
-   Earth-leakage protection trips
-   Coolant leakage at the heater or pipe seals
-   Damaged supply cable or overheated connector
-   Poor cold-start performance because coolant circulation through the heater is blocked

## 🛠️ 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
