Thanks, Jim your video and replies were very helpful. I've got a 1999 Civic. I noticed the temp gauge climbing today (1st hot day since I replaced the timing belt 7 water pump. I read your replies to Jjay Troche. The fan runs when jumpered. I checked the fuse. I opened radiator cap, turned on heat and ran car for about 10 minutes. The fan never kicked on. I'll be ordering thermostat(for the fan - Honda PN: 37760-P00-004). Thanks again.
just replace my old swithc and my fans they dont work any more .. ill put back the old one .. do you know why with the new one fans they stop working is any chance that the switch is bad .. cus is brand new so.. please help thanks
i figured out whats wrong the coolant sensor which goes into the the thermostat housing is bad i tried the paperclip trick and the fan worked fine its a 1998 Honda Civic EX 4cyl could you give tips on how to replace the sensor looks like you might need a deep socket as my regular socket was to small
Hey Jim, I did the following troubleshoot and with a wire shorting the coolant sensor, the fan came on. So that indicates that it's either the temperature sensor or the thermostat to me...does that sound right to you? As an aside, I now can't get the wiring clip to slide back on to the sensor. Do you know what would cause that? Did I bend the prongs in the clip when I put the test wire in? Any advice appreciated. Thanks!
I am not sure. If you find all the same connectors, it should work. I would call your parts guy at the Honda dealer, and ask him how many coolant sensors your engine has, and what they go to. If it is 3, then it should be the same. Here is another video that talks about the 3 sensors the Civic engines from 96 to 2000 use: ruclips.net/video/JEXiUUtpiuE/видео.html
I just bought a 1994 Delsol and my radiator fan comes on right when I turn on ignition and or stays on when the car starts. So basically it's always on and does not work properly as per temperature. I asked previous owner if they bypass the fan but they said no. I disconnected the tempt switch and the fan still come on or stay on when car is on. It's not allowing my car to get to normal operating temperature so I guess I am failing smog test. The top radiator hose is HOT while the bottom stays cool, which is not normal. What you think might be the issue? I replaced the thermostat already.
Check the battery, the alternator. You could also have a pocket of air in the cooling system. If they did not maintain the coolant, it may have eat up the water pump.
Can I leave my jumper wire plugged in and leave it that way so that it's always running? I'd like to leave it that way so I never have to worry about it not turning on Is it safe or no ?
You can do that. Honda designed it with the switch, so your engine can come up to operating temperature quickly. By just turn the fan on from the start, it will take longer for your engine to warm up to operating temperature. Pretty sure this will also make your gas mileage go down.
Hello so I replaced my thermostat my switch and my relay even change radiator fan in my fan still won't kick on when I get to operating temperature when I bypass it by putting the paper clip the fans turn on you got any ideas even change radiator cap to make sure everything is nice and sealed
If the paper clip works the fan, then it is the thermal switch. Most likely you have an air pocket in your coolant. You can test your switch: ruclips.net/video/Lcx_TlOKkFU/видео.html
I changed the coolant switch and my fan still doesn't turn on while engine is hot. Fan was tested prior to this with my battery and it turned on, so I know it can't be a fan problem. Any advice would help
tubejim101 Air in my coolant? Elaborate on that one for me please lol Are you referring to a possible head gasket problem when you say that? A bad thermostat can have something to do with the fan not cranking while the engine is hot? Thanks for your response.
Hondas are known for getting a pocket of air in the cooling system. You have to "burp" them, to get air out of the lines. Will find a link to a video. A thermostat not working when it should, can cause your coolant temp to do strange things too. As for the fan not coming on. If you short the connector as in the video, and the fan does not come on, it is either your wiring (not likely) or your relay (most likely). Or the fan, but you tested that good with battery voltage. So you have two problems. Temp acting funny (thermostat or air), and fan not coming on (relay bad). Hope that helps.
Hello, I tried the jumper wire method to the fan switch. When the car is in accessories, the relay does click but the fan still does not come on. I jumped the radiator fan to the battery and it also comes on. I feel the wiring connected to the radiator fan itself is bad as I have no continuity, would this be the case
@@enjoiskateboardingSB I suspect you have a bad relay. You know the wire going from the sensor to the relay is good, because when you jump it, you can hear the relay. It is a bit tricky, but if you can figure out the relay pin out, you can pull the relay, and should be able to jump, or supply voltage to the fan, where the relay would.
I have a 99 Civic LX car was running great till a while ago car started to over heat and i noticed the radiator fan wasn’t kicking on. I check the fuses and relays swapped them around and nothing fan wasn’t kicking on. I did the paper clip test boom fan kicked on so i Replaced the thermostat and the Fan Switch. Immediately i saw when it got to operating temperatures the fan would kick on for about 30s then turn off for about 2-3mins then kick back on for another 30s I found that odd even when engine was starting to over heat the fan would not stay on constant. Any suggestions?
Sounds like you have a pocket of air in the cooling system. It can take quite a long time to "burp" the system. Here is a video on an Accord. It is the same, but you have no bleeder valve to open: ruclips.net/video/mfTapX0DuQ0/видео.html
Make sure you are running good coolant. Should be running 5 year universal coolant. Get the pre mix so you don't have to worry about mixing it with distilled water correctly.
I did the old switch around fuses today just to give it another shot and see and did the paper clip diagnose and for some reason fan didn’t come on wen back tried to turn on the condenser fan and AC functions not working now 🤦🏽♂️ no lights blower motor doesn’t turn on swapped fuses around again and now nothing wants to work
i replaced the coolant temp sensor...and replace relay 1 of 3 in my fuse area...then i did the jump with paper clip on the sensor connector but the relay still doesnt activate a clicking sound and fan doesnt come on...any suggestions would be appreciated..ty
02 rav4...the relays are good..as i tested from my second temp senor..and fan is working...i have narrowed it down to the harness connector that goes to the temp sensor...looks like a difficult fix....not much room to work and i may have to cut the wires then splice them into the new harness which i have yet to buy..probably a dealer part
2013 F150 5.0 My fans seems to be running on high when they dont need to be, any suggestions? Causing a louder vaccum sound than it should, even if its just idling

@@tubejim101 ah i see, well i wont hold tou to anything but i beleive its my radiator fan which is electric, seems to run immediately on start, then a few minutes after will run on high and wont stop unless its been off for a while, its definitely not running hot though

What "new one" did you install? If it was the fan switch in the coolant. You most likely have an air pocket in you coolant. You will need to "burp" the coolant system.
Help my 96 Honda Accord has a fan on the left and right up against the radiator. The one on the right as your looking down into the engine compartment won't turn off. The engine is off and it's still on full blast.
Dear sir my car problems is when the engine is running while 2 or 3 mins running of engine the fan didn't on when I turned on the ac the fan will on than what's the problem with it
2000 Oldsmobile silhouette. Front fans aren't turning on. This is all that has happened radiator was crack replaced it . Power steering went out replaces pump. Power steering worked for awhile then got tight again . Car stay cool for a week or two then fan stopped turning on unless it never did and I missed that. Test-drive down Rd cause replaced temp sensor started to over heat then all of a sudden power steering worked and needle went down and went don and up little bit . Could relay cause this
I work on Honda Civics 92 to 00, and Accords 90 to 93. Long time ago, i had an Oldsmobile Silhouette. Was a great car, till it stated needing maintenance. And like yours, everything started falling apart. Sold it, and bought a 2007 Toyota Highlander. So far the Highlander has only need an alternator.
tubejim101 i hope you may be able to assist. i have a 2001 honda accord hoses thermostat changed as well as fluid. The ac fan doesnt go on all the time when im checking the fans while the ac is on i spin the ac fan with my fingers and then it starts to spin everytime not as fast as the other fan but car then cools down what should i check
I really only work on 90 to 93 Accords, so i am just guessing on other years. Sounds like your fan motor is going bad. Looks like they go for about $55 after market: amzn.to/2tIlAAp
What if your cooling fan doesnt turn on like its supposed to going down the road? It turns on with AC, comes on during idling, or if I let the car sit and warm up. As I drive it the temp runs a little passed the middle. Is this an electrical issue?
@@tubejim101 it is a chevy cavalier 2000. Not sure if the vehicle is supposed to run at around 220 degrees but it wasnt like that when I first got it. Fluid has been changed, air has been bled from coolant system, pressure tested and its good, tubes and radiator have been flushed, water pump is new aftermarket, heater core blows hot air and no leaks, new reservoir cap and doesn't have a radiator cap, and have tested it for blown head gasket. The fan does cut on but ive noticed that when I am driven the vehicle that the fan doesn't come on unless I turn the AC on. I feel it may be a power issue as GM cars are known for electrical issues...especially Cavaliers.
@@tubejim101 thanks so much for replying but I got it . I never cleared the code after replacing sensor as soon as I did I drove it for a while and boom fans kicked on . Thanks again .
my fan works only in 1scale and not in the second one "fast" any ideas whats the problem? have change thermostat and thermo sensor but still same think
Think early on, American car fans where driven by a belt. Then over time they switched to an electric fan. So, they seem to have always been an all, or nothing setup. Imports into the American market, seem to have kept to that too. The 92 to 00 Honda Civics are all on, or all off setup.
No I have a 2011 dodge durango. I put the paperclip in, and started the vehicle and the fan turned on, but was really fast. Once I reconnected, it stayed on really fast until I shut off the vehicle
I've replaced the switch and the relay and fan and it still doesn't turn on. The Fan comes on if i jumper wire that connector but I've put 2 switches on it and it still isn't coming on.
Yea I was wondering the same thing.. I have two fans, and I thought one of them was spinning, but now it’s not.. but after reading, it sounds like it only kicks in when the engine is hot enough to need the fan.. is this correct?
Ive been looking for this vid the past 3 yrs jaja so Im having this problem of my fan not kicking on the strange thing is when I jump it as you did, it kicks right on.. But my switch and thermostat is brand new? so??? did they sell me a bad switch? new thermostat new switch, new relay yet the only way I can get the fan to kick on is when I jump it, its driving me nuts jaja sorry D15b 91 civic
I've replaced the switch, was told the thermostat was replaced. And I've done the paper clip method and the fan turns on. What could be making the fan not work normally?
my ac run good the fan won't run fuse relay are good . the radiator fan not run when hot. i take the fan put in other car the fan run good . i chang the temperature sensor the fan still not run need help

@@darthraider501s4 Need to burp it. This video will help with testing the switch: ruclips.net/video/Lcx_TlOKkFU/видео.html
I've replaced the switch, was told the thermostat was replaced. And I've done the paper clip method and the fan turns on. What could be making the fan not work normally?
What is the year, make, and model of your car?
@@tubejim101 it is a 1998 Honda civic dx
Here is how you can test your switch: ruclips.net/video/Lcx_TlOKkFU/видео.html
If the paper clip works, and switch tests good, then you most likely have an air pocket in your coolant.
I'll try those. Thanks!
my ac run good the fan won't run fuse relay are good . the radiator fan not run when hot. i take the fan put in other car the fan run good . i chang the temperature sensor the fan still not run need help
Might have air in your coolant.
@@tubejim101 i bleed the air but the fan still not run take for dive 20 mile not over heat tempreature the same just the fan not run. i unplug the cooling temperature sensor the fan not one .next i will chang cooling fan resister see what going on
@@chee75 If you jumper the connector like in the video, and the fan comes on, then the problem is in the coolant switch side of things. Here is a video to test the switch: ruclips.net/video/Lcx_TlOKkFU/видео.html
@@tubejim101 i put new one today i jump the harness the fan not run . i got 2004 corolla and 2006 corolla the bad one 06
@@chee75 All this info, is for Hondas from 1996 to 2000. Not sure how Toyota does it.
my civic overheats when I i stop at red lights or stop sing it cools down when I hit the gas i do it because it helps me cool it down
Does your fan come on when you put the wire in?
yes
If your fan comes on when you put a wire in it, but does not come on when the engine is hot, it is most likely that coolant switch that is bad.
Same issue with my civic dan was running and stopping wasnt staying on

My fan works and I jump the plug and I hear the the relay click but fan won’t turn on
Sounds like the relay.
tubejim101 the plug to the fan is not getting power
