That's an issue, I'd get that checked out. Did you replace the thermostat too?
I just drove from Denver to Vail (5200ft to 10,000ft at times) and the temp never ran over 190. The radiator is larger capacity and 2-row, so there's a lot more fluid for cooling.
No electric fan, I don't see the point at this time. It's a temp sensor, I was in a hurry, so I need to clean up the wiring in the future. The inlet/outlet diameters are different on the rad than OE, so I had to use a coupler to get the hoses back down to 1-3/8in. This jointer happened to have a sensor bung, so I can monitor the temps.
