180* Fan temp switch..Anyone know where to find one?

I ordered a Spal 185* on/165* off temp switch that screws into the radiator...WELL, the POS activates at 190* and off at 175* so its not what I am looking for...

Anyone have any idea where to get a GOOD 180* on / 170*ish off temp switch that is the standard 3/8" NPT...?


I'm searching the usual places(jegs/summit etc) and not finding much...only some no name cheapies...

I want this thing to run no warmer then 180*.... This lincoln MK8 fan will cool it down to the 160* stat no problem but it needs to be activated correctly.

I found this switch but I am leary about it since its a no name...maybe its worth a try but....

I need one that just goes to ground once the target temp is reached. The Spal switches do this but they are too hot to start with and even then activate 5* higher then rated...

Im still looking...

Seems for a 180 stat most kits use a 185 on 170 off. here is a single spade self grounding but as i mentioned 185 on.

I would buy one of the 30 dllr adjustable jobbies and dial it in to turn on and off wherever you want.

Looks like the Derale switch you linked first may work...I looked it up on their website and it is self grounding, it just has 2 spades for dual fans. Its the only one I have found with a 180* on temp..... I may give it a shot.... I really want to keep this thing at 180* or less...

Thanks for your efforts!! I will hunt around some more in the morning and if I don't find anything I will try out the Derale switch....I just hate to keep dumping $30 each on these switches until I find one that works....

You will find the switch your looking for, is an on and off switch.

Is your switch on the inlet or outlet tank? If it's on the outlet side, I would expect the temp range to shift up and narrow like you're seeing.

The switch is on the left(driver side) tank...just under the upper radiator hose inlet. I didn't think about the sensor location varying the temps....hmmmm

I would still think since it's on the inlet (hot side) of the radiator would work accurately.

Re: 180* Fan temp switch..Anyone know where to find one?

You know I DID see the Zirgo 180* switch...I kind of questioned it's quality as I have never heard of that brand of anything but....Summit sells them, it may be the best bet. I wouldn't mind one of those adjustable dealies I could set if right where I want it but those all have the probe thing...I want to use the type that puts the sensor in the coolant, not the fins.

I may just roll the dice on the zirgo. I will let this thread run until this afternoon and see if anyone else posts up ideas, if not then I'll try the Zirgo and hope it's accurate..

Thanks bro..

Re: 180* Fan temp switch..Anyone know where to find one?

I have heard of Zirgo but never actually used them. Could google and see what others think. I myself have a maradyne which is a 185 deg one. Had thought about trying something lower like the zirgo but really have not had any issues for me to try it.

How about an adjustable switch, so you can put it where you want it?

I got mine from Flex-A-Lite- works great!
