it turns out that the problem was the thermostat... my dad removed it a while back and i guess that prevented pressure from building up in the cooling system.. got it replaced and now everything runs great! haha. my check engine light came back on though after just fixing it for the smog check..

Glad you found one of the problems. I am not convinced that the radiator is OK since you described that when the drain was opened, coolant trickled out instead of flowing heavily. I would also keep an eye on the coolant to make sure you don't find oil in it otherwise you will need to replace the head gasket.
so ive searched the forums a bit and looked for overheating issues with the 300e, and ive done a coolant flush (replaced it with the Zerex G-05), changed the oil, and o2 sensor.
The car still runs hot. I know that this car likes to run hot but my car climbs up to 110 and stays around there a lot. Sometimes it jumps to 115. With the heater on full blast it'll cool down to 100, but never really goes down past 90-95. Is there something else wrong here?
when i was flushing the coolant, i noticed that there was some white/beige creamy stuff on the cap and oil-like substance floating around in the coolant tank..
i really hope its not a blown head gasket since its so expensive to fix and im a college student. i love my benz, but i dont have the funds to fix a head gasket.
also another problem i noticed was that when i tried to flush the coolant, i opened up the little wingnut kinda thing on the bottom of the radiator (left side if you're looking at the car head on) and coolant barely trickled out at the speed of 2 drops a second.. Is it supposed to come flowing out or am i opening up the wrong part?
(sorry if this post is so fragmented)
If your is overheating for long and is still driving it, you will damage your head gasket. Oil is mix with your coolant, that is why you have white/beige creamy substance in your coolant.
A car that overheats is a sign of water pump problem. Fixing your waterpump and head gasket is the only solution to your problem. Your cylinder head may also bee warp due to your car is overheating so long.
