FAN BELT TENSION
When tightening fan belts, loosen the generator
adjusting bolts and pull out on the generator by
hand until the belt is just snug. Under no circumstances
should a pry bar be used on the generator
to obtain fan belt tension or damage to the bearings
will result. Some engines have an adjustable
fan pulley flarlge for belt adjustment.
When adjusted correctly the fan belt should
have betweer~ :~/4/’ to 1" deflection on the long
side. (On narrow belts this should not exceed

CYLINDER BLOCK WATER DRAINS
When the cooling system is to be completely
drained, there are one or two drain plugs on the
right hand side of the cylinder block depending
upon engine models, which drain all cooling water
which might be trapped in the base of the block.
Figure 74--Water Drain
CAUTION: OVERHEATED ENGINE
Never pour cold water or cold anti-freeze
into the radiator of an overheated engine.
Allow the engine to cool and avoid the danger
of cracking the cylinder head or block.
Keep engine running while adding water.
WATER PUMP
The water pump is located, in the front of the
cylinder block and is driven by the fan belt from
the crankshaft pulley. The inlet of the water pump
is connected to the lower radiator connection and
the outlet flow from the pump is through integral
passages cast in the block.
No lubrication of the pump is required except on
the M and B series as the bearings are of the
permanently sealed type and are packed with special
lubricant for the life of the bearing.
The water pump requires no attention other
than bearing replacement when they show excessive
looseness or if a water leak develops which
shows a damaged or badly worn seal that needs
replacement.
COOLING SYSTEM PROTECTOR PELLET
All Continental engines are shipped with a cooling
system protector pellet in the water outlet header.
The pellet should be allowed to dissolve in the cooling
system.
This pellet will dissolve in the cooling water with
proven results as a rust inhibitor and water conditioner.
It can be used with all types of anti-freeze.
ENGINE HOUSE VENTILATION
Engines operating inside buildings must be adequa.rely
ventilated to supply sufficient air to cool the
engine -- provide air to mix with the fuel and in
addition, to carry the heated air from the building.
