I agree. That is a pretty normal. I have an 04 and I had been having temp problems for the longest until recently when I had to do a head gasket swap. I would recommend replacing those plastic elbows with the aluminum ones and making sure you bleed the system very thoroughly. You do that by taking the tstat housing off and filling up the LIM through there. Once you have enough coolant in there, put the housing back on, fill up and top off your radiator. Once the radiator is topped off, leave the cap off, open your bleeder valve, turn on your car, put your heater on full blast and let it get up to running temp. Check your upper and radiator hoses, once they both feel equally hot it means your tstat opended up. Constantly squeeze your hoses to get those air bubbles out and fill up the radiator as needed. Once you see a steady stream of coolant shooting out of the bleeder valve and you are getting some pretty good heat inside the car, close the valve, put the cap on the radiator and you should be good to go.
