The radiator core could be getting plugged up. You could try the flushing job yourself and it may work but a qualified radiator shop will probably do a better job. Make sure to use a long-life coolant without silicates or borates.
Silicates will cause the water pump seals to fail over time because they are abrasive. Also, silicates tend to settle in the lowest and coolest place within the cooling system and will cause plugging of the radiator core over time causing overheating. Borates cause pitting corrosion on the cylinder heads. Use the more expensive "good" stuff. You won't be sorry in the long run.
I wouldn't say the increased cooling temperature is hurting anything but it certainly isn't normal and should be fixed soon.
: My 96 me overheats sometimes after i have been driving for about 30 minutes. It seems to only happen when i am cruising in 4th gear or when i am sitting at a stoplight. The temp gauge almost gets to the 3/4 mark but never goes beyond this. It seems to reach this point and then goes back to normal. What could this be? I took it to the dealer but they couldn't duplicate it. I am hurting my engine by driving this.
