Re: BBC temp creeps at idle; how did factory do it?

Just for informational purposes. As I mentioned, my sbc would creep way up in temp when sitting at idle, a/c on, in traffic. Start driving and temp would come down to about middle of gauge or slightly above. Then, took the truck off the road to do rust repair and paint. One year later, I put the truck back together with a new smaller (not heavy duty) 2 core aluminum radiator. Now, it seems my temp sender is broken. Temp gauge has never made it to half way. Stays in lower range of gauge and never goes above half way mark no mater the outside temp a/c on or off.

It was my old radiator causing my temp issues!
