Recently replaced the stock radiator and the alternator, and then performed a cooling flush and an oil change.

When the car sits at idle the temp gauge will barely make it to the N in Normal. The heat is usually on when testing this. When the engine is rev'd, the temp gauge will sometimes fluctuate very quickly all the way up past the R in Normal, and then almost as fast go back to its original position below the N. When the gauge does go up like that, the heat starts blowing harder and also feels a lot hotter than it normally does.

I have let it run for an hour or more and the temp gauge never goes past the N unless the engine is rev'd. I am unsure what might cause this, but any help would be much appreciated.
