The engine temprature warning light sensor – 1 – and self-sacrificing anodes – 2 – are
situated next to the thermostat housing – 3 – . The anodes resist internal corrosion in
the cooling system.
The self-sacrificing anodes – are checked regularly and replaced if more than 50% has
been eaten away by corrosion. Undo the anodes – 2 – and replace them with new ones,
including new gaskets.

removed – 3 –. Check the thermostat by submerging it in hot water. Always use a new
gasket when re-installing the manifold.
Draining the cooling system – is done by removing the lower sacrificial anode.
