Overheating issues
 

Hi Guys,

I'm having a strange issue with my RX8, i have tried searching but haven't found any issues like this before.

The temp gauge usually stays a little to the left of centre the whole time I'm driving the car, however the other day when i was giving it some go the gauge moved up to about 1/2 if not a bit over this is the highest it has ever gone since I've owned the car.

Before this i also noticed that the fan has been staying on a lot longer than it has done before, i could just be paranoid?

Any ideas on why i would suddenly begin to overheat? i haven't lost any coolant and all the radiator foam is in place and under normal driving the car is fine, even in traffic at long stand still periods.

thanks in advance!
