Ok so i want to install electric fans on my 92 coupe. So this is my idea.I know the 89-90 240sx have a coolant temp switch on the lower radiator hose. Can i use that to turn on my fans? Also whats the name of that part or the part number so i can get it from nissan. I been searching but couldnt find much.The part looks like this.

This is how you wire it, you need a thermal switch at 160-185 degrees

If you were using the in-hose switch, you'd want it on the upper hose. It'd never turn on with it in the lower hose

It's more ideal at the top, but depending on the T-stat close temp and switch temp it could work. Coolant temp switch for fans is best placed at the hottest place which would be the head, but you need a switch rated higher then the opening temp of the T-stat. Now lets say a T-stat is rated at 180 degrees.... It does not open at 180, it may start but they typically open 10-15F after the rated temp. The rated temp is where the t-stat closes.
