when i first got my car the overheating scared the beejezus outta me. I changed the water pump, the old one was platic, the new one is metal, and the old one was in perfect condition. I had the thermostat changed and I flushed the coolant and ran a conditioner and the strongest cleaner for the coolant as possible, and it still did nothing. Now I just run it with the defroster on all the time, when I come to a stop then it kicks the fan on and I'm cool sailing. When I drive, the wind keeps it cool. Normal driving I only get into the "A" range. At stops and lights, it will cool down to the "M". I'm just a little caustious is all
