Mazda RX-8 Radiator Light Comes On
Mazda RX-8 Problem
Average Mileage: 60,150 mi (24,500 mi - 101,000 mi)
I noticed about 50,000 miles the radiator light would flicker on and off. The engine temperature alwys stayed in the normal region and the radiator was full of fluid. The Mazda repair guy told me that this is accuring in a lot of the RX-8s. There is a plastic waffer on the gauge ball inside the radiator that measures the fluid. When the waffer starts breaking up, the gauge ball starts fluctuating greater sending a signal that the radiator is low on fluid. But it actually is not. Cost $900.00+ to replace the entire radiator just for this tiny plastic waffer.
