Hey, this is a kinda off topic question, but that's the difference between the 160 degree thermostat and the 180 degree one in the GP store? I mean, I know what the numbers mean, but what effect does that have on your car? I bought the 180 degree one, but should I have bought the 160 degree one?

And you're probably right about the fan temp. If you read the Coolant topic, I'm DEFINITELY leaking coolant now. It didn't used to be puddling on the ground, but now it is, so whatever it is, it's getting worse. I'm taking it to get it checked tomorrow. Since I poured more coolant straight into the radiator, I haven't had any problems with the temp trying to go sky high on me.
