ENGINE COOLING SYSTEM
2. DESCRIPTION AND OPERATION
1) GENERAL DESCRIPTION
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions. When the engine is cold, the cooling system cools the engine slowly o
r
not at all. This slow cooling of the engine allows the engine to warm up quickly.
The cooling system includes a radiator and recovery subsystem, cooling fans, a thermostat and
housing, a water pump, and a water pump drive belt. The timing belt drives the water pump.
All components must function properly for the cooling system to operation. The water pump
draws the coolant from the radiator. The coolant then circulates through water jackets in the
engine block, the intake manifold, and the cylinder head. When the coolant reaches the
operating
temperature of the thermostat, the thermostat opens. The coolant then goes back to the
radiator where it cools.
This system directs some coolant through the hoses to the heat core. This provides for heating
and defrosting. The coolant reservoir is connected to the radiator to recover the coolant
displaced by expansion from the high temperatures. The coolant reservoir maintains the correct
coolant level.
The cooling system for this vehicle has no radiator cap or filler neck. The coolant is added to
the cooling system through the coolant reservoir.
2) RADIATOR
This vehicle has a lightweight tube-and-fin aluminum radiator. Plastic tanks are mounted on the
upper and the lower sides of the radiator core.
On vehicles equipped with automatic transaxles, the transaxle fluid cooler lines run through the
radiator tank. A radiator drain plug is on this radiator.
To drain the cooling system, open the drain plug.

4. CATALYTIC CONVERTE STRUCTURE
The Catalytic converter of monolith type
consists of 2 walled metal bodies which is
made of Cordierite.
The principal element of converter consists
of the materials like Alumina or oxidized
Serume in order to apply to Ceramic
Monolith.
Washer coat operates first, and catalytic
metal elements (Pt, Pd, Rh) operates to
washer coat next.
Monolith type is lighter than other types,
easy to manufacture and quickly approaches
to proper temperature.
Washer coat is used to make a contact
surface with exhaust gas bigger by adhering
closely to small holes of inner layer.
If a lead compound or phosphorus adheres
to the surface and the temperature rises, its
surface is decreased.
The total area of general monolith converte
r
is about 45,000 ~ 500,000 ft3. (10 times of a
football field)
Generally Alumina (AL2 O3) is used as a
raw material and its 7 phases of gamma,
delta, theta have big areas and high stability
for the temperature, and nowadays gamma
Alumina is used usually.
