First off, my car is a 2002 Z28 with about 45k miles on it.

Tonight, when coming home from hockey, my check gages light came on. It was about 40 degrees out, and I was in 6th gear on the highway going about 75, and the temp needle was up into the red. It would go down for a while, but then spike back up, and did it about 4 times over 10 miles or so. It didn't happen again when I got back to city driving. When I stopped and popped the hood, the fans were running, and I thought I heard something boiling.

I have noticed my fans staying on after getting out of the car for the last couple weeks, but I don't drive very often, and it happens kind of randomly. My car has never showed this before, and I'm guessing it's overheating.

Any suggestions, opinions, or thoughts?

I'd flush the radiator and check to make sure the high-speed settings on the fans are coming on before anything else. Also make sure the radiator isn't obstructed by debris.

The boiling sound I heard leads me to believe I'm low of coolant, so I'm going to pick some up today. My buddy told me the same thing, so I'm going to do that and check the radiator for debris. I'll report back.

OK, I just got back from a drive after putting some more coolant in. It is now in the "full for cold" range.

It doesn't look like there is any debris on the radiator.

The car is maintaining hotter than normal, about halfway between vertical and the hash to the right (I guess that's supposed to be 235, since vertical is 210 and red is 260), and will climb up to 235, and spiked up to about 250 a couple times before coming down within 5 or 10 seconds. I seem to remember straight vertical being the norm before.

How do I bleed to system of air?
