Radiator Construction [Mzi-3.5]; Thermostat Construction/Operation [Mzi-3.5]; Construction; Operation - Mazda CX-9 2007 Service Highlights

RADIATOR CONSTRUCTION [MZI-3.5]

• 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 mounting rubbers are utilized to decrease
vibration.
• The radiator has an ATF oil cooler in the lower
radiator tank.

THERMOSTAT CONSTRUCTION/OPERATION [MZI-3.5]

Construction

• A wax-type thermostat with a jiggle-valve has been adopted.
• Stainless steel has been adopted on the thermostat body for excellent corrosion resistance.

Operation

• When the engine coolant temperature reaches 79.5—83.3 °C {175.2—181.9 °F}, the valve starts opening to
allow engine coolant to flow from the radiator stabilizing the engine coolant temperature. The valve fully opens
when the engine coolant temperature reaches approx. 94.5 °C {202.1 °F}
