Griffin radiator and twin fans still running at 190-200?

OK folks. All fixed. Bought the better stainless steel spal sending unit which is 3/8" thread. Got rid of the stupid reducing bushing and went straight in the manifold with the 3/8" Spent time trimming and fitting that bottom radiator hose. Filled the griffin radiator with the evans coolant solution and fired her up. Car go up to 185 degrees and both fans kicked on. Temp gauge pretty quickly dropped to the 165 and the fans shut down. Took her out for a spin and she runs at a cool 180 now.

Glad that everything seems to be working. I still don't like that temperature range though. Not sure about your engine, but my engine would be VERY unhappy at 165*F. And honestly, I'm surprised it actually dropped to that temperature. If the thermostat is closing like it should, I would think that you would end up holding at the thermostat closing temperature (which was 180 right?). The fans might cool the water in the radiator still, but, if the thermostat is closed that water isn't circulating, and the fans aren't going to have a tremendous effect on the water circulating through the engine. Some, but not that much.

If your engine is happy with those temps I guess that's fine. I know mine wouldn't be, and that's why I set my fans to keep it between 190 and 200.
