absorbed in the radiator for sake of vacuum.
2 Cooling recycling system
Water pump is driven by belt, coolant flow
in water pump from left bottom side of
radiator, coolant is pumped into the
peripheral empty cavity of cylinder liner
through coolant tubes in the shell of the
cylinder. Coolant flow in cylinder head
coolant tubes through cylinder head gasket
hole, then flow in the sub- branch system of
thermostat. Tubes of inlet manifold lead
coolant to the thermostat, when the
thermostat is shut off, cold engine coolant
can’t return to the radiator to carry out
recycling, preheat the engine quickly. When
engine is preheated to the full, the
thermostat is open to let coolant flow into
water inlet housing mounted on the upper
right position of the radiator. The recycling
is performed when coolant becomes cold
gradually after flowing in the water outlet
housing mounted on the left side of radiator
through level core tubes.
3 Cooling fan relay
As to information and diagnosis condition
of cooling fan relay, you can see the cooling
fan illustration for reference
4 Coolant temperature control system
switch
The switch control the voltage of cooling
fan relay, as to the position which relay
make the fan running at a high speed and
diagnosis, under the condition of coolant
temperature exceed 95 and 102 ,you
can see electric system of engine.
5 Explanatio
n
of coolant
Notice: You can add antifreeze agent in
order to raise boiling point of the coolant,
but solidifying point will be effected if you
add excessive coolant, you are not allowed
to use antifreeze solution exceeding
70,because it will freeze from this point,
temperature will go up rapidly, pure
antifreeze will freeze when the temperature
is -22 (-8 ).You can comply with
direction of draining and refilling the
cooling system, you are only allowed to use
certain coolant regulated by Cherry
Company while adding or replacing the
coolant,50% and 50% mixture of
ethylene-glycol and drinking water will
provide the following protection:
● Provide -39 antifreeze protection
● Provide 131 boiling point protection
● Prevent rust and corrosion
● Keep appropriate engine temperature
● Make the warning light and thermostat
work normally
6 Explanation of coolant reclaim system
Reservoir tank
Reservoir tank is the transparent tank just
like common windscreen gasket cleaner
canister, reservoir tank is integrated with
radiator through hose, it collects the
overflow coolant when the coolant
temperature is high, otherwise these coolant
will flow out of the cooling system, level of
coolant should be on or much higher than
the position of overflow hose in the tank.
