Mazda RX-8 Problems

Radiator Light Comes On

Mazda has issued Bulletin No. 01-010/10 for the above issue:

Some vehicles may experience the coolant level warning light comes on even though the correct amount of coolant is in the coolant reserve tank and radiator. The coolant level sensor float in the coolant reserve tank (A) is deteriorated and absorbs coolant. The float gets heavy, and sinks, causing the the coolant level warning light comes on. As a mass-production change, the design of the float has been modified.

Replace the necessary parts according to this VIN range.

• For VINs JM1FE****** 100000 to 157837 (built before July 1, 2005), replace the tank with sensor.

• For VINs JM1FE****** 157838 to 403405 (built on or after July 1, 2005), replace the tank only.

New Climate Control Unit if Heat/Cold Knob Won't Adjust to Right Temp

If the climate control's heat/cold knob is not adjusting to the desired temperature, a new climate control unit may be needed.

Hesitation Caused by Sticking Secondary Shutter Valve

Hesitation and/or a lack of power can be caused by the secondary shutter valve (SSV) in the intake manifold becoming stuck open due to carbon build up around the SSV shaft. This may occur with no Check Engine light illumination but eventually the light will illuminate with code P2070 (Secondary Shutter Valve [SSV] stuck open). The cleaning procedure described under the service bulletin is a long process and it is recommended to install the updated SSV actuator and gaskets. The SSV is activated at higher RPM and the carbon accumulation can happen when it opens infrequently. The effects RX-8's built before April 18, 2007.
