weird overheating issues
I have 04 sti
about a week ago i noticed while seating at a light that my car temp started to rise, I turned on my heater to try to drop the temp but it blew cold air at first then to warm then hot. So i pulled over as soon as i could to see if i blew a hose or a radiator cap, no leak noticed. My overflow reservoir was full to the top, when i got back in the car to see if the temp kept rising but the temp somehow dropped to normal operating temp,i let cool down and popped the radiator cap off to refill with fluid.After that i drove around and then home and i didnt have a problem, almost like a fluck.
the next day i was driving normal and notice the temp come up again and i was on the highway this time , but before i can move over to pull over the temp just dropped back to normal like the gauge was going or somethign. but i pulled over anyways and my reservouir was overserviced again
it just been consistently doing that for the next few days it will rise then drop to normal
I spoke to bunch of subbie owners and they all aggred that the thermostat is the cause of the problem. so i replaced it yesterday burpped the system for 6 minutes at 3500rpm's all bubble are out ( i forgot to mention i tested the old thermostat and it checked good-open properlly and at right temp) took it for a test drive and same thing happen , temp got high then cam back down. got home let cool check oil levels -good- check for milkiness or traces of coolant for blown head gasket-good- psi check both radiator caps -good- ( on radiator and reservoir for turbo) so im up s%^t creek with no answers. Fans do come on but dont know what the duty cycle is or if their coming on properlly or at the right time but they do come on both of them. help!!!!!
thanks for any help in advance

Sounds like you checked most obvious things. Maybe a Conti tech could have a look at the vehicle.
Call me for a reservation
