I just now did your trick to my 02 focus........trick worked like a charm......thanks so much.
What type of stereo wire did he used
what kind of wire I have an 02 zx3 and are they connected to the bigger relay fuses?
Why do I feel like I'm.stoned watching this video
Lol fucking brilliant 😂
my focus 2000 have the same trick and it works great no more overheat
I had the exact same problem and found the solution. Start your car at diagnosis mode ( keep pushing the button near speed meter while starting your engine). When in diagnosis mode release the button and push it about 40 times until you see a "16-30 C" temperature indicator. That is the perceived heat of your motor. Push the gas to see whether if your fans will kick in. Fan has 2 speed levels, low and high. Low should kick in at about 80 Celcius and high should kick in at about 105 Celcius. In my case, Level 1 fan kicked in only after 105 celcius. Which means the low speed fan trigger isnt working. Replacing the big fuse that is next to the big green one solved the issue for me. Big green fuse activates after 105 Celcius and the one next to it activates at 80 celcius. If you dont see temperature increase even though you keep hitting gas, then your sensors are the issue.
Pese the nombre of the fuse , big green 30 amp but Witch position of fuse
Just run that wire into the cabin & hook it up to a toggle switch and you can turn the fan on at a stop light.
thats the same thing i DID TO A 79 hONDA. If i WAS DRIVING AROUND TOWN STOP GO STOP GO, iD LEAVE IT ON.
Somehow RUclips can read my mind sometimes. I bought a 2000 Focus yesterday, and it started overheating at a stoplight. Didn't even mention it to anyone. I was already scheming to hardwire the fans on, since they were not running.
Thanks for bringing this to my ATTENTION!
Pro mechanics charge me almost $700, waste of money mechanical insurance covered about $100, it's still overheated. About a year later I figured out it was the resistor, $20.
Hey man, I know this is an older video now but I'm wondering if you remember which terminal was the positive terminal in the relay?? I want to try this method to see if the fans work. Cheers!
0:56 now that's how your intake should be. 👌
I was lucky all I needed to do was power wash my radiator it would overheat around 60 MPH now I get past 80 no issues
Does this actually work?
Power wash?
From outside or inside?
This guy is so great, never watched such a fun car repair video like this. Thank you! :) :)
Lmao!!
Change the cap of the antifreeze bottle, but be sure to put the original one. I had a problem for a year and solved it quite by accident yesterday. Everything is OK now.
Supposedly you can pull the CHT sensor connector off and that will cause the fans to run all the time.
having the exact same problem, I replaced everything, but I didn't replace the engine cooling temp sencor, I wonder if it's going to help, In my fuse box I have the fuse that keeps popping in the number 6 slot. it's the fuse that goes to that radiator relay,it looks like the same problem is happening everywhere though thank you from sacramento
Thanks for the video cuz I'm having the same problem I changed the thermostat brand new radiator but I do notice I don't have that green relay that you have maybe that's the problem maybe when I swapped out all those parts I got here in the line going to check that out soon
Someone before hacked relay owners manual should verify green relay 1 extra thin tang (5) ground , instead of just four R15 driver side front corner low speed, R16 high speed is next to it ,is not the one cover of fuse block has the #s stamped on it...hope this helps just repaired bad thermo resistor on fan housing.. pick a part salvage yard should have in vehicles about $ 30 in parts store 10 for relay at yard ...
I have a 2000 focus, i have replaced all that stuff too, im going to do this next 👍
If u still have overheating is bc air in the system u need to drill a 1/4 inch hole on the thermostat so when u fill radiator water can pass through to fill the other portion of the tube and bubble will release through the thermostat hole and will reverse to radiator cap while filling up once all bubble stop radiator system is completely fill with water or coolant. And once all done engine will be safer and head gasket will never burst .
I did this hack and it works
Im glad it helped you. Thanks for the comment and watching my video
Thanks bro. I have the same problem, thumbs up
Love it.
03 focus with a bad head temperature sensor. Going to try to bypass it also.
Good evening how are you doing today my name is Joe toomer do you have to take the fan fues out
That is just what I need buddy I’ve tried everything could you possibly show how you connect that ground wire in detail what peg on the relay to rap the wire and do you just attach the other end to the body using a pk screw ?? Please let me know I’m desperate cheers Larrysullivan
Yo, if you don't have the right pressure cap on the reservoir you will lose pressure to the over all systems. Mine was off by a few kpa and started dumping coolant. Compare the motorcraft OEM to the after Market to make sure.
could you have just bypassed the relay by running the wire the other side of the relay?
Pro trick : watch series on InstaFlixxer. Been using them for watching lots of of movies lately.
@Frederick Maximiliano yea, been watching on InstaFlixxer for since december myself =)
@Frederick Maximiliano yea, been using InstaFlixxer for years myself :D
Guys It's a air problem because of the motor position it's a manufacturing defect you have to bring the back of your car in min 2o+ angle and after that u have to take the air from the defect production motor block
Air in engine block?? Please tell me details how i get the air out.thanks
P Z Hi, if u r in us or eu u can buy a cooling system refill tool like this one amazon link is in the info.
Sadly I'm in Turkey i had no chance to find and use this tool but looks like a A good solution.
ruclips.net/video/_WCRcuCZI50/видео.html
Or u can do it like me in a alternate way language is Turkish but u can see the logic check this video out.
ruclips.net/video/kokIXX28-zI/видео.html
Thank you for your fast response. I'll try it
It's not work for me this trick. Maybe I do something wrong. In this video I don't understand the procedure. Any help??
i’m have the same over heating problem with my ford focus !!
Brilliant, thankyou so much big help
Dang that boi W I D E
Only one of my fans come on when i unplug cylinder head temp sensor i plug it jn and it dont work its a new sensor
Man, I messaged b4 about disconnecting the head temp sensor & that worked fine until it smoked my alternator! I ran power to each fan & they both run! My temp sensor, fan solonoid & replaced the smoked terminal, relays, fuses, thermostat & all that is new! Still my fans won't run! Wish you showed exactly which pins!!!!!!???????
Bizarre to make a video about bypassing the relay and not indicate where the wire should be connected! One end is grounded; the other?
Engine cooling relay loses ground so he taps ground from ignition relay it is printed on it read ground symbol or right side tang towards front he didn't show exactly how he jammed in there typical hack work , not a good example ford wiring clusters suck lemons hard... 🤔👍✌️🙏😔💪
Can you tell me what number on the relay you connected to? I couldn't get it to run the fan maybe I am on the wrong relay.
From what I seen he ran ground from ignition relay to engine cooling fan relay ground (gréen) it loses ground wire connection in the loom under fúse box...
I have the same problem
2010 Ford focus
But the fan needs a PWM signal to start working
I have temporarily hooked up an arduino running a simple blink program
Also, which fan is for the A/c & which is for cooling the car? Im considering disconnecting 1 And then running the other constantly!!!
The low speed fan comes on to cool the radiator. The high speed fan comes on when you run the A/C or the defroster or the engine temps get very hot. Both fans can come on to provide even more cooling when things get really hot.
what he need is a swicht (on and off) connected on the dashboard and play acording time running and temperature outside.
Oh yes ...thank you very much..
My car ford focus se I m at stop light 6,7min for show me engine hot temp and fan coming on I open the driver side door to enter , out the vehicle
you saved my life
Thank you, I did the same thing on my car it run fine for few weeks until the battery light came on has this has to do with the wire??? Anyone?
Two fans direct all the time fry the alternator pulling 80amp all the time...thats why the system comes with temp sensors to activate the fans at certain temps.
Blocked radiator core internal or external fins. Water pump impeller blades snapped of or missing. Pressure loss in coolant system from leak or expansion cap. Coolant temp sensor or thermostat is stuck only partly open. Head gasket leak. Nothing else it can be.
Which terminal is the positive on the relay…🤷♂️
i was having similar problem .. but it was the condenser fan not working i replaced and im not sure if its turning the right way ... does both fans pull air from the front ? or one pulls and condenser blows ?
They both pull if condenser fan blows opposite cut and swap wires (change should reverse fan) poles otherwise it will overheat in hot conditions ac will perform poorly..
But why the temp panel doesn’t kick off here. Did disconnect it as well? Just hoping this wont affect the whole computer system.
Some say running the fans constantly burns out the alternater. Is that true?
Probably yes, because it has to be start work when it’s need
Does that hose from the top right of the valve cover have to go onto your intake because I just put a little filter on the other end of the hose
You can use a filter. It will be fine
ProjectFlip is it normal for air to come out of the oil fill
Its normal for it to ventilate a little bit. But if it seems like a lot is pushing out then do the cap test to check blow by. With the car running, remove oil cap and place it on top but do not tighten. If the air coming out is strong enough to push the cap away, then you have excessive blow by and that can mean worn out internals of engine or possibly other issues.
ProjectFlip it has good power and does not burn coolant but is running lean and did the pvc line and hose and o2 scensors and rpm only goes down only slowly only when I’m in motion and when I’m completely stopped the rpm will go down fast ty for helping me I had this problem for 5 months now
ProjectFlip it just vibrates and does not come off
I have the same problem right now 😕
What Guage wire did you use
If your in AZ then WHY is that ENGINE Bay so NASTY?
Long story short, I couldn't figure out what was wrong so I just rigged up this wire to run my cooling fan all the time. You should do home electrical work on the side, for extra money.
I had the same problem with my last focus... it ended up being the resistor for the blower motor. not the cooling fan resistor. it melted wiring and f'd everything but hey i made it an extra 100k before it caught fire in the under hood fuse box and had to be towed home.... and then it started again it was driven onto the tow truck 200+k mile on original drivetrain and overheated 100's of times lmao. my new one does not overheat as of yet. but it would have been cool if you could pull the 2 fuses and show the slots in the resistors that you used. but all in all great video man.
one day maybe we will all be as smart as greg, until then we will have to do what we have to do to get by.
What type of stereo wires are they
the fans remain on while the car is running or they come to be paid at some point
I noticed that intake you have on your car. Is it worth getting it? Cuz i seen those for like $50-60
Id say its worth it. It gives better throttle response and you can feel it on the top end as well.
Can you adapt a swich inside the car? to turn it on only when it's hot
Yes it is possible to have it set up on a toggle switch.
When I open my oil fill cap on the valve cover air comes out is that normal
Yes thats normal
@@adeltopic1209 you
I would suspect a failed PCV valve or collapsed PCV supply pipe.
How do I know where to put the speaker wire :(
Good job !!!
Hey bro, I keep coming back to your video! I thought: Hmm maybe my high speed fans work good & that is why my fans spin when I run 12v to them & maybe the "low speed" is bad? I can run 12v & ground to each fan & they work! BUT, like the idiot that I am, I PAID THE $98.00 & BOUGHT NEW COOLING FANS, DID NOT FIX IT!!! THEN I BOUGHT A NEW 70AMP LOW SPEED RELAY (THE GREEN RELAY) ANOTHER FAIL!!! I have replaced the water pump, thermostat & housing, cylinder head temp switch & cooling fan relay & wiring harness, grabbed the 2 black relays from a junkyard focus, EVERY PART OF THIS COOLING FAN CIRCUT IS NEW & STILL NO LUCK SO, I CUT 1 OF MY HEAD TEMP SENSOR WIRES & RAN WIRES INTO THE CAR & MOUNTED A TOGLE SWITCH! YES, It set off a check engine light but, I can shut it off with my cheap scan tool. I wish I had a better scan tool that showed my actual engine temp but, your idea works & I THANK YOU FOR ANOTHER WAY ARROUND THE PROLEM! I WAS SIMPLY RUNNING MY FANS CONSTANTLY BY DISCONNECTING MY CYLINDER HEAD TEMPATURE SENSOR BUT,That ended up frying my alternator! so, I am now on my 3rd alternator & it was time for something new! I ordered an aftermarket cooling fan controller but, the temp sensor was 3/8ths=way 2 big! it's a single wire set up & the focus has a 2 wire head temp sensor! I WONDER IF I SHOULD USE THE 5V REFERENCE WIRE OR THE 12V WIRE TO RUN MY AFTERMARKET COOLING FAN CONTROLLER OR IF IT WOULD EVEN WORK THAT WAY? ((IM LEANING TOWARDS THE 12V WIRE?) ANYWAYS, I laugh when watching your video because, I as well have replaced EVERYTHING & STILL, NO LUCK! I like how you mock the other video's!!! tho, it has to be a short in my wiring or a bad ecu? so, I simply cut 1 of the hed temp sensor wires 7 ATTACHED A WIRE THAT IS LONG ENOUGH TO RUN INTO THE CAR, CONNECTED A TOGGLE & RAN ANOTHER WIRE RETURNING FROM THE OTHER SIDE OF THE TOGGLE SWITCH, BACK TO THE OTHER END OF THAT CUT,"TEMP SENSOR WIRE" & NOW I CAN HIT THE TOGGLE & TURN ON MY FANS & NOT HAVE TO RUN THEM CONSTANTLY! YA, it's a pain but, it's easier on my electrical system, I can run my subwoofer amp & when I need my cooling fans, I also ran my sterio remote wire to a different toggle so, I can still listen to music just without the bass when I need to run my cooling fan, sometimes I consider disconnecting the A/C fan & letting the other cooling fan run constantly but, that scares me! I don't want a draw on my electrical system! I am considering this kit on amazon that has a digital display so I can see what my temp truly is??? THANKS BRO!!!! Wish I knew what the real issue is w/my cooling fan set up??? f'n ford! but, everything is new on this car so, it should last as long as I keep my eye on the temp gauge!!!
I am having same problem. Fuse 6 (30 amps in europe) was blown, replaced that. Now everything is ok (no overheating) but fans are not blowing.
Janne Raatikainen unplug your cht sensor (plug right above altenator) and turn car on to see if fans work. If fans come on then this jumper trick should work for you. If the fans do not come on, you will need new fans
But my problem is that car runs fine (no overheating). Fans just keep off. I measured the resistor and checked the resistor connector and they are fine. Normally it runs about 93-95 C temperature, but if I let it stay idle, temperature raised to 103 C and still fans didn't run. After that I powered it off. (sorry about my rally english, but you probably understand).
I don't know much about engines. Is the connector one of these ? www.raatikainen.org/extra/jako/focus/focus.jpg I am a bit afraid to break something. :)
Janne Raatikainen that looks like the duratec motor and not the zetec motor from the link you provided. As far as the temps go, that is normal operating temp. As long as the car does not overheat, i would leave it alone
I made a test for the fans. Driver side (left) fan shows short circuit and does not react if I rotate it with my hand. Other side fan shows some ohms and they increase if I rotate the fan with my hand. I tried to run them with external 12 volt nimh battery, but neither them worked.
Wheres the oil cap
its better for the engine without it, it can breath better for more horsepower :) :)
You can disconnect the head temp sensor & the fans will run constantly! I have the same issue! Everything is new on my zetec vin-3 focus yet, my fans won't cycle! I am so frustrated & I have had to replace the rod & main bearings twice because the zetec has a heat threshold & running it to cold or to hot will ruin the rod bearings quickly!!!!
Doing that causes the engine light to come on. Thats why i went with the bypass. I agree tho. It is frustrating. Ive replaced everything too and a buddy of mine hooked it to his computer and manually turned the fans on to make sure low speed and high speed worked. Both passed but fans still would not cycle properly. Havent had any bearing issues yet and i beat on this thing daily.
ProjectFlip so did you find out what was wrong? because i have the same problem but don't wanna burn out my fans
I havent figured out the issue as of yet. Ive replaced pretty much everything and still no signal to turn fans on at the appropriate times. Im still running the bypass myself and probly will swap the fans for some aftermarket hi performance fans and keep them running as a constant. This is a common issue with this car and alot of people are letting the fans run.
Does changing the water pump help ?
It can help if your waterpump is starting to fail. If you are are a long idle and notice your temp rising, rev the motor a few times to see if the temp drops. If it does you may have a faulty waterpump. The waterpump also has a weephole which coolant will leak through if it goes bad. You can check on the passenger side of the block to see if there is any coolant trails coming from waterpump.
I'm having the same fucking issue
This nigga hella funny. Thanks!!
Yo i got the same model man I'm about to do this. I can't make it ten minutes down the road
Give it a try. Hope it will help you out. Im still running with the bypass till this day.
@@JoeFasho my ford fiesta 2003 1.6 when I fill up the coolant, then drive for like 30minutes the pressure builds up and opens the expansion tank but no any warning light.what would be the cause?
@@MAKOMERE you could have a thermostat that went bad and its not cycling the coolant due to being stuck closed. This can cause back pressure in the system and push it out of the expansion. You could also have a bad radiator/coolant reservoir cap. When those go bad it is not able to keep the pressure and releases.
Grounding out a positive pin would not be advisable. If you have replaced all of those other things and you have to rewire a relay, maybe try replacing the relay?! Relays are electro-mechanical. The mechanical part tends to fail quite often in relays. The relay will be alit cheaper than the other parts. If replacing the relay does not fix the issue, then whatever activates the relay is your issue. If you have replaced what activates the relay, its probably the wiring between the two.
You are going to burn out your resistor connectors or even your relays
Why not run a wire from the fans to the inside with a switch to turn on and off so they don't run constant.
Yes ,leave it in on position for a couple minutes and you run down the battery. Henry Ford is killing himself again.
It's soo dramatic 🙄 🤣 😁😁😁😁😁
The whole point of electric fans is so they dont have to run constantly. Why not just fix it right? Nice quick fix tho
Thank for watching rick and for the comment. In one of my later videos i fixed the issue with the fans using the sct tuner by controling when fans come on. Originally the computer was not turning the fans on until it was too late.
Mmm faster way people unplug the sensor by the alternator and the fans will automatically stay on fast and easy
Yes but that will throw a cel. I didnt want a cel. The little light bugs me lol.
Hey man them fans ever burn out? lol
Nope. Still running strong
@@JoeFasho how many miles later
I no longer have the car but i had it like that for almost a year

Good evening how are you doing today my name is Joe toomer do you have to take the fan fues out
