Did this video help you?

99soonerstang: I tested everything like you did and replaced the thermostat and the switch but it keeps trying to overheat, I have fluid movement through the radiator and I had my fan kick on after changing the parts but now it's not coming on while I drive any suggestions??

Robert Paradiso: Great vid Good lookin, thx

Larry brin: good video! but shorting the sensor with a paper clip means "ultra high temp" which triggers the high relay. if your low relay is bad you will get a false idea that it is working. meed to add the correct resistence which will vary for every car. a better test is to turn car on, list if fan turn on on 1/2 mark, and listen if it runs faster after 3/4 mark. you can know if low relay is bad also if your temp gauge blows past half mark but never past the 3/4 mark... usually. nothing is 100% sure in cars :)

Sia Xiong: When I put the paper clip in the plug turn the key my fan won't come on till I touch ground somewhere then it comes it..wat does that mean 

Mark Gardham: Thanks for the video man, helped me out a treat! Now gonna grab a paperclip and test this relay!

t kelly: hey, nice video! It really helped me with my fan problem on my 94 civic. Thanks!

social seahawks fan: Why would the fan work ONLY when the car is running but shuts down immediately when turning the ignition off? I know it used to run for a few minutes after turning off the ignition but it recenty stopped working that way which makes no sense especially since its been hot this summer.

Ross Gordon Wensor: Thanks heaps, Really helpful

Kent Jackson: Was the car on when u connected the alligator clips to battery to check the fan?

Armando Soriano: My fans wont come on at all it keeps on overheating I don't wanna drive it or else my car will be trash I need help I change the thermostat and nothing I think the fans are no good and I need to buy them new one thing for sure I have a lot of oil leaking in my motor like in the bottom of it idk why 

otsb506: This was a very well done video and showed exactly all the steps in order and in a way that was easy for me to understand! Thank you very much! Bob

Alvaro Barquin: +1 !! You saved me a lot of time and money on a garage!! Thanks a lot for posting this video.

norwegcat: Excellent step by step troubleshooting video! Nice job!

Armando Soriano: My fans wont come on at all it keeps on overheating I don't wanna drive it or else my car will be trash I need help I change the thermostat and nothing I think the fans are no good and I need to buy them new one thing for sure I have a lot of oil leaking in my motor like in the bottom of it idk why 

Christopher Davis: Thanks for the awesome vid. U saved me lots of time and money!!

riki Ramirez: I replaced everything and my fan still wont come on so i just have a wire to keep it on with the ignition but i dont wanna keep it like that :/

Jonathan Ramirez: Hey Snag, I bought a '96 firebird and the previous owner has a toggle switch installed that turns the fans on and off manually, not automatically. I then found out there was no thermostat in the firebird. I bought it because it passed smog, but I just want the fans to turn on automatically. Why did the previous owner do this and how can i make the fans automatically kick in?

oldskool funk: Great Video SnagEasy, Don't worry about the haters that's never going to stop just keep on doing what your doing, the haters have personal issues and cant see past their negativity and DO NOT GET IT, so keep moving forward and let the haters make you better bro Great Job.

Abu ALI: NICE 

kevykev38: If the fan runs by jumping the two wires going to the fan switch sensor? It is showing the relay and harness in place is working properly. So it would point to a problem with the thermostat (even if new) or even a bad thermo Switch. ( even if new). Test both. Out of the car with boiling water and a multimeter on the thermo switch. Testing the thermostat in boiling water you should see it open.

BboyV3n0m: nice video!

ThePenguinCompound: Nice!!

Kelvin Feliciano: You are not shorting nothing out, you are sending power to the coil inside the relay. kid

Seth Buxbaum: it worked on my acrua tl and i was pulling my hair out, thanx alot man.

Osvaldo Cardona: how would you check the other relays? 

ImAdapt73: Narrow screen? WTH?

Tino Lopez: Thx man my fan relay was my problem for my 91 integra..

Selwyn Robles: This was a helpful video. I encountered different problem with my radiator fan. when a/c is on the fan is functioning at low speed and fan speed doesn't change even the temperature gauge keeps high which affects the aircondition, but when the a/c is off , the fan will function in high speed when it reached the mid temperature. I am wondering what to be changed or to be repaired. hope you help me.

Mars Flee: Thank you! You fixed my problem.

cafesoul Kafesoul: I was told that the Cooling Fan switch is located on the radiator itself, and that the cooling fan switch next to the thermostat is to keep the temperature gauge inside the car's dashboard working. I have already replaced the fan, relay, and cooling fan switch (attached to the radiator--since the temperature gauge is working). The fan still does not turn on. Any suggestions?

camarobossman: great video you are the man. you really helped me understand a lot about how all this stuff works

Glenny Glenn: Good stuff brah!

Cristian Martinez: If my raidiator fan doesnt turn on after replacing fan relay, cooling fan switch, and thermostat can i just put a paperclip in the cooling fan switch like in the vid when he tested it and keep it like that? Because with the paperclip the fan turns on when the key is in the on position.. And also my fan does turn on with the paperclip test so idk wat else it could be

Kent Jackson: What's the torque setting for radiator fan switch? 

Cristobal Rodriguez: Thanks for your video, it save me a lot of time and money. I found out that my cooling fan switch was bad, even before troubleshooting I was thinking was the radiator fan motor. ThAnks

Doug Seifman: The fan is a simple DC motor, it doesn't matter if you connect the clips backwards. The fan will just turn a different direction. 

Robert Martinez: im having truble with my 98 accord so I turned on the a/c to check my fans work. they come on for about 15 20 sec. and go off and kick back on. I took it out for a test drive and its still overheating. the fans did kick in ehen the gage was about 75 %. what could be the problem

ghostrider993: Great video....it worked for fixing my 97 Honda Civic...Thanks

tubejim101: Great video

Nataly S: Hi! I have a question, my car needs the connector, but can't seem to find it new. Do you know where I can get it? or does it come when you buy the switch. Maybe a dumb question to those who know, but I really don't know lol. Thank you!

Munir Shahab: Honda Hot & Cold Diagnosis

HarmanGill64: I cant get the cooling fan switch out with any of the wrenches i have!! 

Feedbacker27: Good video and good English dude. Don't lose your accent, if you do, you lose your uniqueness and with that the ladies too!

Clay Natvig: sometimes my fan comes on and sometimes it won't causing my car to overheat, does that mean that the thermostat is probably bad? if the relay is bad would it not come on at all??

Gregg Hancock: If you only have 1 wire to switch how would u short it

andrewscott10: thanks man!!!

Slim: Thank you Sir, your videos helped me a lot. Thanks again.

Christopher neita: very very good

Tina Navarro: Thank you!

MrKoolaidman909: its good to replace yur coolant fan switch and thermostat n all but why not just wire yur fan direct to ignition ... i mean thats what i do to all my cars ... i wire my stock or aftermarket stereo head units directly to power n how yu do that is cut the power n ignition wire on the head unit n wire them together n wire them 2 to the power wire of the dash harness ... n result of that ... yu have the ignition wire from the dash harness side just chilling there ... so what i do is i cut / splice n extend just the positive wire of the cooling fan ... bring it thru the fire wall the way yu would a 4 gauge for a sub system ... and wire it to that ignition wire ... that way yur fan is on at all times ... the moment yu turn to ignition with yur key ... now in doing it ... yu wont even need yur key in the ignion to turn the radio on yu just press the power button n its on ... that way yu wont have to have yur fan on wile yu listen to the stereo when yur car is off ... do this to all my cars ... old n new ... keeps under the hood cool at all times
