05 ‐ 3
GENERAL INFORMATION
Description
The cooling system consists of the following:

Engine Coolant Temperature (ECT) Sensor

Fan Assembly

Radiator and Cap

Thermostat and Housing

Degas Bottle

Engine Block Heater

Coolant pump

Coolant
Walter C. Avrea, the owner of patents 3,601,181 and
RE27,965, has granted Ford Motor Company rights with
respect to cooling systems covered by these patents.
The ECT Sensor is used by the GCP to obtain coolant
temperature information. Refer to Section 8 for further
information on this sensor.
The coolant fan blade can either draw or push air
through the radiator to help cool the system coolant.
The radiator allows excess heat to be transferred to the
air. The radiator tanks cannot be repaired. The radiator
cap maintains system pressure. This pressure raises the
boiling point of the coolant and helps prevent vapor locks
in the engine block and cooling system.
The thermostat prevents coolant flow until it reaches a
specified temperature. At this temperature, it will open
and allow coolant flow through the engine and radiator.
The thermostat and housing are serviced as a unit.
The radiator degas bottle holds a surplus coolant when
the engine is hot. It also replenishes coolant back to the
system as it cools. The degas bottle allows air
separation during operation which reduces engine hot
spots.
The coolant pump circulates the coolant through the
engine block and cylinder heads to the thermostat. If th
thermostat is closed, the coolant returns to the coolant
pump through a bypass hose. Once the coolant reaches
a specified temperature, the thermostat will open,
allowing the coolant to flow to the radiator for heat
transfer and back to the coolant pump inlet.
Engine coolant provides freeze and boil protection to the
engine and cooling components. In order to obtain these
protections, the engine coolant must be maintained at
the correct concentration and fluid level in the degas
bottle or coolant expansion tank.
Coolant is made up of a 50/50 mix of ethylene glycol
permanent antifreeze and water. This mixture is to be
used year-round with temperatures above -34.4°C (-
30°F). If recycled coolant is used, it must meet Ford
specification ESE-M97B44-A or WSSM97B44-
D.
CAUTION: Not all coolant recycling processes
produce coolant which meets Ford specification
ESEM97B44- A or WSS-M97B44-D. Use of coolant
that does not meet specifications may harm engine
and cooling system components.
CAUTION: Do not use alcohol type antifreeze,
alkaline brine solutions, or 100,000 mile, red in color
antifreeze. This may cause serious engine cooling
system damage.
