I too was having overheating issues, had been noticing prior to rad, water pump, timing belt change along with some other stuff. this that the temp gauge seemed high normal. Hooked up the scan gage after parts change sure enough, was as high as 218 under normal driving during the one week of hot weather here. Was dreading the thermostat change then read the tread about the fan clutch. More money, (150.00 new) but could be a easy fix. Sure enough, temps running no higher then 184 and normally in the 170's since change. So, moral of the story, do the check on your fan clutch to see if that might be the cause.
