COOLING SYSTEM DESCRIPTION
RADIATOR BYPASS LINES. Allow the coolant to circulate
Cooling system components are:
through the engine block, without going to the radiator.
WATER PUMP. Pumps the coolant through the cooling system.
Water temperature regulators
FAN. Draws air through the radiator core to remove heat from
Radiator bypass lines
ENGINE OIL COOLER. Cools the engine oil.
TRANSMISSION OIL COOLER. Cools the transmission oil.
Engine oil cooler
Transmission oil cooler
RADIATOR. The radiator is a sealed pressure type radiator.
Coolant flows through the inside of the core and is cooled by
the inside of the core and is cooled by the action of air flowing
through the outside of the core and around the fins.
WATER TEMPERATURE REGULATORS. Control the tempera-
ture of the coolant by restricting the amount of coolant flow to
the radiator. When the engine is cold, the regulators will stop the
flow of coolant to the radiator and allow the coolant to recircu-
late in the cylinder block until it is warm. When the coolant is
warm enough the regulators will begin to open, allowing it to
flow through the radiator. When the engine is completely
warmed up the regulators will allow a full flow of coolant
through the radiator to maintain the engine operating tempera-
