A trail fix for a bad temp switch (in the radiator) is to find a crimp-on style spade lug (the "fork" type, not the ring type) that is about the same size as the two prongs sticking out of the temp switch. Then you can just pull the connector off the switch & plug your spade terminal into the connector. This will let the fan run all the time & get you home. I carry a couple in my emergency kit..... saved my bacon once already.
