My RX-8 keeps giving me the low coolant light. I know what you are going to tell me and the answer is yes, there is coolant in the reservoir. I only get the light when i run a gear more than 2 mins. and after i press on the clutch, it goes out. Car not over heating but i am concerned that maybe the water pump is cavitating. Any one else having this problem? A fix maybe?

There are some threads on here about S1's having a faulty coolant sensor. I dont remember exactly but I think it was Mazurfer that did a little DIY on a fix.

I'm also having the problem - there are a number of threads on this forum regarding it. Some tried to fix and failed, some tried to fix and fixed, most end up buying a new sensor (~$100), some ignore it and check their coolant when they check their oil every other fill up (not recommended in the event you truly do lose a catastrophic amount of coolant and don't realize it). I'm going to attempt a fix once the weather turns; if that doesn't work I'll buy a new sensor.

as kiker showed you ^ there are multiple threads about this... it's normal.

If it bothers you enough, disconnect the sensor and the light turns off. That also means to be more proactive in checking your coolant level from now on.
