Radiator Construction; Construction; Operation - Mazda RX-8 2004 Service Highlights

RADIATOR CONSTRUCTION

• A corrugated fin type radiator has been adopted.
• The radiator tanks are made of plastic and the
core is made of aluminum for weight reduction.
• The down-flow direction of water inside the
radiator causes air to bleed from the cooling
system easier.
• Four rubber-insulated mounting brackets are
utilized to decrease vibration.
• To improve both the cooling ability and the sporty
design, the radiator is designed to tilt forward to
reduce the height and to take in the air from the
inlet installed under the bumper.

THERMOSTAT CONSTRUCTION/OPERATION

Construction

• A wax-type thermostat with a jiggle-pin has been
adopted. The thermostat body is made of
stainless steel with excellent corrosion resistance.

Operation

• When the engine coolant temperature is below 80°C {176°F}, the valve closes and lets the engine coolant
circulate inside the engine to improve engine warming performance. When the engine coolant temperature is
between 80 °C {176°F} to 84 °C {183°F}, the thermostat begins to open the valve and engine coolant flows to
the radiator to stabilize engine coolant temperature.
