This is the first time my legacy has ever done this but here it is, my 2001 legacy started to overheat on me twice today, first time was going through the drive thru and it spiked up to 3/4 of the way then immediately went back to normal, after which I got on the highway traveled 75 miles, then had to go through a town with some stop and go traffic then it happened again. I have been noticing that the over flow tank has been filling up somewhat and today after these two occurrences it was over flowing.
What I was thinking is that it could be the radiator car is bad because it is the original one so I replaced it and haven't really drove it since. The head gaskets were done about 60K ago and the thermostat should be fail proof meaning that if it were to go bad it would stick open.
I'm just looking for some input on this, like I said I may have fixed it with the new radiator cap but haven't really drove it yet.
