Hello
I have a 1995 polaris sportsman 400 and i need to get a thermo sensor for it, but polaris has stopped selling them... is there anyone who could tell me where to find one???
From what i can tell polaris kept changing the style of it from 93 and up so i think the one i get will have to be for a 95.
Thanks for the help!!

 

Do have 1/8 pipe fitting on the sensor? If you knew the OEM original resistance or ohms of the good sensor you could find one from napa.

 

was this the pn#3084284SWITCH
if so when i did a seach to see what else it was used in, it comes up w/ alot from 97' to 07' in atv's and sleds lol.

 

where did you search to find that

 

Is that the sensor in the rad? PN 4110099? Your talking about?

 

on the polaris parts break down. it's the sensor in the engine.

 

The sensor is the one on the radiator i'm pretty sure it's part # 3084284, from what i'm being told from a few different dealers polaris doesn't stock it any more.

 

the pn# that i gave you and you just posted is the sensor in the engine. the pn# that tlc gave you IS the one that goes in the radaitor. that number was used form 1990 to 95' in diffeernt models. when you do check the pn# out on ronnies.com, it doesn't list a pn# or even a replacement for it. maybe as mentioned if you could find the resitance you might be able to match one up from something else w/ the same threads. good luck.

 

If you get a thread size then you can get a rad sensor from a auto store.

The thread sizes for my rad sensor ,Polaris 4010161. is M16x1.5. Turns out a rad sensor from a 84-88 Nissan Maxama or 86-99 Nissan stansa works.

There opening and closing temps are a little different, the will fan kicks on a little later and off later but well within over heating safety margins. I Know a guy who has used one for 3 years now.

I,m sure you can find a alternative as well. Heck you may have the same sensor and it just has a different Polaris number due to the it having a different end wire connection only, in that case just splice your old 2 wire to the 2 wires of the new sensor.

 

I know this is too late for helping Sportsman95, but cross checking pipe thread and operating temps, Polaris part# 4110189= $29.80 or 4010202=$68.00, will fit this machine, it has 1/2" pipe thread and opens around 175 degrees then closes at 155 degrees. I to looked for this, but came up empty at first. I went with a variable temp switch to control the fan, and put a water temp probe in the radiator where the sensor was bolted, (with the gauge under the seat to keep somewhat protected,as I dont do any deep water crossing) to see exactly what operating temps i run,and adjust fan accordingly. If the variable switch fails, the wiring is right there to put in a rocker switch for key on fan if needed
