The water pump is fairly new but the radiator is original equipment.

What puzzles me is the stock temp gage sits smack dab in the middle of the NORMAL range when the temp is 217. Only during spirited driving does the gage creep up and even then it's still in the NORMAL range. For my own piece of mind, I replaced the stock gage temp sender. It seems rather odd that my engine is running hotter than it should but the cluster gage reads as normal.



THAT IS WAY HOT, the stock sender range is so large that the EEC will be pulling timing and trying to cool it down LONG before that gauge moves. If your seeing it move at all even within the normal range its hot. That gauge is just there if something catostpohic happens and you get hot fast.

Something is wrong with your set up, your not doing damage yet but your losing a ton of performance. My SC 3L temps ran at 205 max temp or whatever the threshold is where the EEC starts retarting the timing. The ADC chip turned the fans on earlier to compensate for it and I ran a little cool at 190 or so on the interstate and 205 pounding on it with 9 psi of boost. Did you bleed the coolant?
