I have a 1990 Accord DX auto and for the past few weeks I have been having overheating issues. Last week I had a shop replace the radiator after it cracked. Ever since it was replaced the car has been running hotter than normal but hasn't overheated yet. Normally, the temp gauge is about 1/3 of the way to H but now it reads a little over 1/2, but only when it idles at a stop light. Is it normal for the gauge to rise that much when it idles? How much worse will it get when Summer arrives and temps start to hit 100 deg? FYI, the fans do work and turn on when it gets past 1/2. Tahnks for any help or suggestions.
