We had some extreme temps last year, and my water temps hit the extreme zone a few times. Oil temps pegged 260F as well. This was just normal every day driving. Plus, this car (FI or NA) doesn't like to be left idling in direct sunlight with ambient temps above 100F either.
I've not had any issues this year, but ambient temps did hit 100F on a couple of days. I've not seen the water temps exceed the usual mark. Oil temps average 205-210F peak. I've only seen it hit 220F after doing some hard runs. Other than that, it's pretty good. Only difference is that the system was burped again the past 6 months, which may have helped. I still hear some bubbling in the heater core at times, though.
BTW, any of you used water wetter? I know nothing is guaranteed, but I wouldn't mind it helping a tiny bit. I've got some Redline over the weekend.
