Coolant filter
A coolant filter is optional. It filters the coolant and adds anti-
corrosion agent.
To avoid adding too much anti-corrosion agent, the filter
must not be changed at the same time as the coolant but six
months after the first coolant change and then every 6
months.
Close the valve on the filter housing before removing the fil-
ter so that the coolant does not run out. Open = pin vertical,
closed = pin horizontal. Use a filter wrench to loosen the fil-
ter if necessary.
Moisten the rubber gasket on the new filter with oil. Screw
on the filter by hand until the gasket makes contact with its
sealing surface. Then, turn a further 1/2–3/4 of a revolution.
Do not forget to open the valve on the filter housing.
