COLD WEATHER PRECAUTIONS
Precautions against damage from freezing should be taken If the engine is to be left exposed to cold weather. Either
drain the cooling system or, where this is not convenient, a good quality anti-freeze that incorporates a suitable corrosion
inhibitor may be used.
If anti-freeze Is used to protect an engine from freeze damage, ascertain whether it is suitable for use in Perkins Engines
and also ensure that it will have no harmful effect on the cooling system in general. Most popular brands (e.g., Prestone)
are acceptable.
WARNING: HARMFUL OR FATAL IF SWALLOWED. If anti-freeze is
swallowed, induce vomiting immediately. Call a physician. Do not store in
open or unlabeled containers. KEEP OUT OF REACH OF CHILDREN.
To drain the cooling system, the taps on the cylinder block must be opened. There may be other drain taps on the
exhaust manifold, oil cooler. etc., all of which must be opened.
When the engine is drained, the fresh water pump will also drain but. In sub-freezing weather. rotation of the pump may
be prevented by:
a.
locking of the impeller by ice because the pump hole was blocked by sediment and the pump was not
completely drained.
b.
locking of the seal because of frozen globules of moisture between the seal and the gland.
When operating in sub-freezing weather:
1.
Before starting the engine turn the fresh water pump by hand; this will indicate if the pump is frozen. If frozen, this
should free any ice formation.
2.
If it is impossible to turn the pump by hand, the engine should be filled with warm water
3.
To avoid this trouble, it is advisable, after the water has been drained, to run the engine for a few seconds at idling
speed. This will disperse any moisture remaining In the pump After an anti-freeze solution has been used, the
cooling system should be thoroughly flushed in accordance with the manufacturers instructions before refilling with
normal coolant.
If the foregoing action is taken no harmful effects should be experienced but Perkins cannot be held responsible for any
freeze damage or corrosion which may be Incurred.
