Does your car run hotter at higher speeds?

if the car heats up at low speeds/idle then its not enough fan. if it heats up at high speeds its not enough radiator. I would check your water level. the factory gauges are extremely inaccurate. to really know what is going on you need an aftermarket gauge.

oh, and it doesn't matter if you've just had it flushed, even if the water coming out was like spring water, it could still look like this on the inside.
from that link you can see just how bad the stock manufacturing process must have been. Both radiators had many core tubes plugged with solder from what looked like the dawn of time.

I still think you'd need a real temp gauge to see if 2 needle widths is even something to worry about...could be that the flush has made the temp sender more sensitive because it doesn't have a layer of crap on it, or could be that the temp is just fine and the gauge is going south... :lol:
