2004 ENGINE
Engine Cooling - Endeavor
GENERAL DESCRIPTION The cooling system is designed to keep every part of the engine at appropriate
temperature in whatever condition the engine may be operated. The cooling method
is of the water-cooled, pressure forced circulation type in which the water pump
pressurizes coolant and circulates it throughout the engine. If the coolant
temperature exceeds the prescribed temperature, the thermostat opens to circulate
the coolant through the radiator as well so that the heat absorbed by the coolant may
be radiated into the air. The water pump is of the centrifugal type and is driven by
the drive belt from the crankshaft. The radiator is the corrugated fin, down flow
type. CONSTRUCTION DIAGRAM Fig. 1: Identifying Engine Cooling Construction Diagram
