Help needed with a Thermo fan

I would use something like this versus the little probes that you stick in the radiator fins. Drill and tap the back of the water pump below the thermostat and you're ready to go. These types of switches are available in different temp ratings. I would definitely want the fan to come on sooner than it has been in your case.

How is the fan relay wired up to operate from the temp sensor? Just the
sensor input alone won't trigger that relay I expect. There must be thermal
switch inline with the relay that needs to know the temp. Maybe when you
replaced the old setup it lost that input along the way?
