Hey gang anyone know the part number or where to get a lower temp fan switch. I’m talking about the brass sender that goes in the passenger head in between the back two cylinders. It has a round black plastic connector on it like a knock sensor. I need around 180-190 degrees. Thanks.

 

Iirc it’s 3/8 npt , search summit racing for a temp switch. They have a lot of different ones with different on/offs.

 

SW555

 

Iirc that’s 210f on

 

Summit sells one that fits that is 180. Although that seems way too low for a fan turn on

 

I'm giving this unit a try. Not sure if it will do everything I want it to, but we'll find out.

Isn't that just a temp sender for the dash gauge????

for you guys wondering what fan turn on times are, here are mine, which are factory. https://www.thirdgen.org/forums/cool...ns.html?nojs=1

 

On my car (L03) that switch controls the cooling fan.

 

If you go to an auto parts store that has paper books still, you can go through them, all the specs and pick virtually any size/thread, on and off temp that you want. I did that decades ago for my car, I used an on at 190, off at 180 for the low speed, then another switch that was on at 210, off at ....something lower....for the fan's hi speed. All with a 160 stat, it worked pretty great, for me.

 

Has anyone every used this one/brand? For $60 you'd think it be the last ever fan control switch. Thoughts? I run around 174ºF at steady state so this would be a great for on/off temperatures I need.
