Correct coolant level is important for the cooling system to 
function properly. Therefore the coolant level must be 
checked regularly.

The coolant should be visible when the filler cap is removed.

Repeated coolant loss normally indicates leakage. The 
cooling system should be checked by a professional. It is not 
sufficient just to top up with coolant.

If the engine boils, coolant will be lost.  Open the radiator cap 
and allow the coolant to cool down. Allow the engine cool 
before filling.

The cooling system must not be filled with salt water, as this 
will cause corrosion damage to the engine.

Replace coolant if it is discoloured or cloudy

The cooling system must then be thoroughly flushed.

Use only glycol-based antifreeze approved to BS 6580:1992 
or ASTM D 3306-89 or AS 2108-1977 (indicated on the 
packaging).

The antifreeze must be intended for alloy engines.

Your Husqvarna supplier can provide the right type of 
antifreeze.

Use antifreeze all year round and even in climates where 
there is no risk of frost.

Antifreeze contains additives that protect the engine cooling 
system against corrosion

The coolant and antifreeze should be changed at least every 
two years.

•

When emptying loosen the lower hose to the radiator.

•

Remove the filler cap.

Fill only with antifreeze and water mixed according to the 
following table.

•

Check the coolant when the engine has run for a few 
minutes after filling. There may have been air in the 
system that has been released.
