all

times.

This

solution

may

require a higher concentration of

antifreeze, depending

the area's winter climate. Check the

solution

make sure the antifreeze protection is adequate.

Should

antifreeze be needed, drain

appropriate

amount

from

the engine block and

add

a more concentrated

mixture.

Operate the engine to ensure a complete circulation

and

mixture of the antifreeze concentration throughout the

cooling system.

Now

recheck the antifreeze solution's

strength.

Place

the

end

this

hose

into

a 5-gallon bucket of clean fresh

water.

Before starting

the

engine, check

the

zinc

anode

found in

the

primary heat

exchanger

engine

and

clean or replace it

water circuit

from

freezing during the winter

lay-up,

well

providing corrosion protection.

Remove
