[DICK SPADARO]

How hot is hot? After reading this post I'm going to go along with GM on this. It is very difficult to address heating issues if the sole basis of a temperature reading is made using stock range style gauges. There is nothing to relate them to, how cold is cold , how hot is hot? Without doing some scale comparison via thermometer or heat scan gun your vehicle could be operating perfectly fine. If it is not boiling over you know that it is less than 212*. Your stock crank driven fan should be adequate even for temps in the 90's if you have a good clean radiator. Before you go spending a bunch of money on retro fit fans calibrate the reading on your dash gauge with a digital reading gauge to determine the actual temperature.
