My car sits at the 180° mark while cruising on the highway, even on 80°+ days. Put me in some traffic and I'll creep up to the 210° mark. I find those temps completely acceptable, regardless of what people are saying ideal temps are. When I'm on the track and pushing it the temps will be more in the range you guys are talking about.
Update 04/26/10
I pulled the front bumper off this weekend to work on my headlights and had a chance to inspect the front half (cooler side) of my install.
There were no signs of rubbing or wear, and the hose was still on completely. It did look like there was any tension pulling on anything, and there were no signs of sweating or seeping. All and all I'm
still very pleased.
I'll be changing my oil in the next few days and I'll give the sandwich plate and fittings there a good look.
