electric fan switch question

I am changing my fan wiring. the old one had a probe type switch that stuck through the fins on the radiator. the new setup has a 2 wire 180F 3/8" NPT thermostat switch. there is no place in the radiator for it, can I put it in the intake?

Thumbs up Re: electric fan switch question

- or ... head(s) (either one) or the water pump (in the upper manifold circulation fitting if avail.) or even the block if wanted
I've used all of the above as the build needed.
I've also seen one screwed into the radiator itself via a threaded bung - not sure if it was something already in the rad. (aluminum in this case) or the owner/builder added ...

It just needs a good location that represents the true engine temp.

Re: electric fan switch question

Thanks john, it seems like it would be most accurate in the radiator (mimium heat transfer)

but the intake it will be!

Re: electric fan switch question

A cheap little trick that worked great on the 67 GMC is a water heater thermostat zip tied to the radiator tank down at the bottom,out of sight. It kicks the fans on and off great and is designed to handle the current. call it redneck if you want but it's cheap and reliable.
