Another Dumb question from a sorta newbie.

[ChevyC102007]

Ive had my ole '71 for 2 years now, ended up having to replace the radiator two weekends ago (dang thing split down the seam between the tank and core). Friend of mine had a 2-core radiator out of a '69 Chevelle he used to own. It works great, truck gets alittle warm but cools right back off (had to replace the water pump and thermostat last December after some idiot stole the original alternator, bracket and battery, put in a long pump for a 74 and moved the alternator to the right hand side.) Anyways, I got a fan shroud from another friend of mine that has an old 67 or 68 sitting out in the back of his farm, looked practically brand new except for one thing........damned thing got warped sitting out in the sun (imagine that) didnt find that until I installed it and my flex fan kept hitting the damned thing.

So..........the long and short of it...................Im looking to upgrade to an electric fan (I know in the past Ive been on the "dummy" side of this upgrade but am slowly being converted that and getting tired of the growling from time to time of the fan hitting that shroud.) I've done a search for ideas for swapping over to the electric fan, and found alot of info except for one? I still have.......................since some of the fans have thermostats on them and require someway of determining when the engine is getting warm i.e a thermo probe mounted either in the thermostat housing or in the manifold, can I hook that lead from the fan thermo unit to the coolant temp sensor on the side of the block? Or should I just drill and tap a hole in the water neck for a pyrometer (I think thats qwhat its called)?

Any and all help would be appreciated..................nopt sure what Im going to go with as for a fan but no offense to the Nissan setup or anything else scavenged but Im gonna go new with this setup (trucks been hacked up enough).

Thanks
