the valves properly ground in, the tappets properly adjusted, cylinder
head gasket tight, and use the correct grade of engine oil.
Cooling System
Capacity
The capacity of the cooling system is five gallons, one quart.
Filling Radiator
Care should be taken to keep the radiator full at all times. The use
of clean, soft water is preferable and will keep the formation of sedi-
ment and scale at a minimum.
Winter Care
An anti-freeze solution should be used for winter" driving. A very
satisfactory solution is one of denatured alcohol and water.
Following is a table of denatured alcohol solution freezing points :

Distilled glycerine may also be used in preparing an anti-freeze mix-
ture. The initial cost is greater than alcohol but it has the advantage
of not evaporating -so that in a season's running it is likely to prove
less expensive than alcohol. Be sure to use distilled glycerine and not
the ordinary commercial grade.
If it is desired to use glycerine, it should •be mixed according to the
following table :

When mixing the solution, always drain the water from the radiator,
mix the ingredients in a separate container and fill the radiator with this
mixture. This is important to insure mixing the solution thoroughly.
If alcohol is. used it will occasionally be necessary to replenish with
additional mixture due to evaporation of the alcohol. In this case, fill
the radiator with a mixture containing a slightly larger proportion of
alcohol.
If glycerine is used only water need be added to maintain the proper
level.
When filling the radiator with alcohol solution be very careful not
to spill any on the hood as it will cause the lacquer to fade wherever it
