electric fan switch

Anybody have a part number from NAPA or Advance for a fan switch that turns on at 180 deg??? I don't want the $40.00 summit one..

I used to have a part number from advance for a standard brand (i think it was) switch that turned on (full ground) at 180 deg, and was 3/8 NPT threads, but i lost it.


thanks, Keith

just go to the local napa store and ask to see the echlin illustrated parts guide.

Part number will start with FS (like FS143) and it should tell you the on and off range.

180 is pretty low
The lowest I have seen at NAPA was a 195 on

FYI---FS 118 is stated as on at 218 and off at 205

I am on my second one now---seems it won't kick on till 250
Does NAPA have the Chinese making the switches now???

I think I will do some research and head for the Chevy store next time around.

yeah the switches are really limited to what you can get.....and even then they rarely work exactly how you want them to....

switch

Last time i went through this, maybe 5 years ago i went throught the same deal with switches. One thing that makes a big difference is the placement of the fan switch. if you put the fan switch up in the intake and the temp switch down in the head you will get a big difference in temp readings. If you place them side by side in the same water stream they work alot closer to the same temp.

The reason i wanted a 180 switch is for drag racing to keep the engine cool. thinking about it i might use a 190 switch and just manually over ride it when i race. If i can find a switch that actually comes on at 190 deg. L.O.L.

I guess i need to make a trip to the NAPA and fight with the parts guy, they are really un-cool around here when it comes to this stuff.

Tell them that you want to look at Standard Parts #TX61. It's a part number that fits most Ford products - no clue on temp setting, but a guess would be 195* or a bit more. Another would be a TX89 which would fit most GM's.

If you are talking about the NAPA store near the York County fairgrounds - not impressed. But neither am I impressed with our local NAPA stores either - which is why I most often use a nearby mom and pop store for my parts "challenges". NAPA takes the attitude here that if it isn't listed for a particular car, they have no clue as it isn't in the computer base.

Yep mom and pop stores are best to go to......or a true speed shop. They will usually help you out.

Back when I was working at NAPA all [b]3[b] yes there was only 3 of use ALL were hotrodders.

Mark had his 46' Chevy 72' impala and his 75' camaro

Chris had his Jeep (title said 67 I think....) and 2 69' camaros

I had my 79' camaro, my 64' Chevy PU (gone now) and my chevette


So we all knew about the hardships of finding the parts.

Too bad that most of these idiots that work in most of the store have no clue how to FIND something.....if the computer wont find it they give up.

SMASH that computer and get the catalogs out!!

There are adjustable temp switches, but based on your $40 comment you probably are not willing to pay what they are asking for them.

Here is a good article that discusses this.

We use this controller on all of our builds & we love them. It is adjustable with pipe-threaded sender that you can install in a water jacket in the intake manifold or block or even in a bung we install in the radiator. They can be set to activate a fan or fans anywhere between 150-240 F with a 15 cycle meaning it will shut the fan(s) down once the temp drops 15 from activation setting. They also have a A/C overide circuit as well which can be used with A/C or a toggle mounted in cockpit for manual activation.
