Something weird happened to me today. I went to put some coolent into my radiator (no it wasent empty and no i didnt bleed it, just filling in the difference). Ran it with the cap off till the car warmed up, and didnt notice the fan turning on. My fan worked the night before, and Ive read that the fan really doesnt kick on till over 200 anyways. My temperture gauge still has the needle somewhat under the halfway mark. Just worries me that the engines running to hot. Drove it for awhile, park the car, and popped the hood. Felt really hot (could just be normal) and the fan still wasent on. But when I run the A/C cold air still comes through the vent (if that has anything to do with anything).
Do you think I should worry? or is this just normal stuff?

So the fans don't come on at all? I think you may have air in the system or not allowing the car to warm up enough. Do they come on when the A/C is on? If so there is nothing wrong with the fans.
Another thing, if you are low on coolant, there is a leak. Coolant does not just evaporate or dissapear.
