How to test your fan temp thermostat switch 

I tried testing with the fan switch resting on the bottom of a shallow dish in boiling water. the switch wouldn't close. I grabbed a wire hanger and suspended it like you did. The switch closed as it should. Great tip! Thanks.

Mr max ; sure was a helpful video. wish I had found it couple weeks back. The answer i was looking for was demonstrated in the shot. My bike has two of those with one working off the other........Thanks.

Good video. I just tested mine by turning the bike on and shorting the thermostat switch, the fans came on straight away but aren't coming on at high heat. I'm now pretty confident the switch is my problem.

Thanks for this video Bro!I just learned something new, Good job!!!

Very simple. Thanks a lot bro

Thanks for the brilliant video!! you've covered more that what I was hoping for.

Thanks for the vid bro, helped me out

LOL! You are the man Max. I like the holder brother...take care

Dude, you're a Genius! Thank You!

Another great vid mate.

Wow thank you for the fast response. Is their such thing as a radiator fan switch and thermostat switch? Is it jus maybe called temperature switch?

Thanks man, solved my problem!

Dude, thank you so much!

Hmm I guess you could run power through it with a test light on the other end. But multimeters cost like $8 and are available at any hardware or auto parts store

awsome. very helpful.

@gladivarious333 To be honest I dont really repair gauges any more, I just replace them. In a speedo or a tach when it gets so rusted that it doesnt work, its not worth it to me to take it apart and clean up all the little bits, especially when I can get a replacement for like $20 on ebay.

You should mention that you must check in all ohm scales on multimeter! Am i right? Cause i checked mine on 2000K and i was reading 1500 kohms .On other scales i was reading 1 =infinite. It took me some time to figure this out.But your video was very helpful .Thanks

i have problem , already second termoswitch have died on me. what could be the problem? i have and old car and i like to do some rally stuf . I use calorstat by vernet termo switches . plz help

Thank You so much!

I have a 250cc gy6 touring scoot. The fan doesn't come on and the gauge does not work it just stopped 1 day. I would like to test or troubleshoot it to find out where exactly the problem is but this is all new to me. I found new parts they are cheap but still dont want to buy something i dont need or have another issue that will blow new parts

I have a 2004 ninja 500 and i need to buy a radiator cooling fan switch. Online i can only find sensors and thermostat switches, but not radiator switches. Help?? Can i buy a radiator switch for a car? And if yes? Which one?

super helpful thanks

@formegolf Thanks dude you too

Are both uses I got a 2 from.ebay bit no way to tell apart they are identical except comme on plastic but no paper with it saying that what one is what how do I know or is only one used and both the same

Would this make my temp light stay on all the time? The fan seems to work normally and it doesn’t get hot I don’t think but the temp light is ALWAYS on..

Is your fan run off a thermostat switch like in this video? Pull it out and test it

can i test it while its still in the car like just leave the engine running to warm it up then check it like that?

What forum member? You have a forum? I want to join it.

I HAVE A 1986 TOYOTA CAMRY AND MY SECONDARY FAN WONT STOP I KNOW THAT THE RELAY MAYBE B/O BECAUSE I REPLACED ONES BEFORE BUT MY PROBLEM CAMEBACK WHAT CAN I DO TO FIX THESE PROBLEM?

I have a 1987 honda,shadow vt1100c pulled bottom radiator hose rusty colored liquid cam out fan will not turn on no over heating lights how do I find water pump and thermastat on my model? Please help

Do you have to pull it out to test? I mean the 1st step would be to test if power is even going to it no? What should it read out as?

lmaooo @ YOUR TYPA WOMEN!!!!

Is there a way you could test this without a multimeter?

How can I test my switch if it only has one terminal inside the radiator?

how to put the multimiter.

Sounds reasonable to me

Shhhhh, I won't say a word to the misses lmao. I guess it won't matter if she watches your videos :D

interesting...

People call it different things. Just look it up on bikebandit's diagrams and order the right part for what you need

I urgently need help with my Chery qq3 2008, I baught this vehicle 4months ago and spend a R11 000.00 so far on it and it is still over-heating. i have done the following: skeamed the block/head, replaced the thermostat, had the radiator checked, tested and cleaned. replaced the water pump and the water bottle......PLEASE HELP!!!!!!!!!!!!!!!

No it must be for your bike. Try bikebandit (dot) com, or your EX500 forum

It probably did doesn't work as well as most of my 80s bikes tho

Problem solved 🙏🙏

Alligator clips are so much easier 😉

I'm sure millions of guys will try this at home.

@Michiganborn1969 She thought it was funny that I thought she would care

the resistance decreases with heat.they are called a thermoster.

Looks like your stove came from the 1980's as well ;)

Damn

It would have been more funny had she woke up & caught you and you told her you were making Japanese motorcycle stew & you called it "Suzuki-aki" Mmmm Yummy

watch out there comes your Wife!!!!!!!
