Sounds like your thermostat did not open or your fan is malfunctioning. I would replace the thermostat regardless if it was the culprit and then check to see if your fan is working properly by letting the car idle until normal operating temperature is achieved. The coolant drain is on the drivers side bottom of the radiator.

All the way up to the H so I quickly pulled over and checked everything. About 5 minutes after having the car off I noticed that I had a lot of coolant leaking, whats that all about? The reserve seemed to be pretty full once I opened it. 45 mins later I drove home and it was just about the half way mark. I'm just really worried something is really messed up. Any experience with this? Also what coolant do y'all use? I want to make sure I use the best and can learn to flush it when needed. Thanks in advance!
