Excellent vid! I was unsure what to do with the high speed wire (Red/Green) but putting it in parallel with the mid-speed wire is a nice tidy fix. Thanks!
When changing a puller fan to a pusher and vice versa, remember to check your fan blades if they are in the correct direction, the blades are curved. Simply reversing the polarity of the motor will make the fan inefficient
+jim c yep. Usually you have to flip the blade
Wish I saw this last year... Lol
@HumbleMechanic ive never understood what flipping the blade is going to do. You cant flip a bolt around and magically have left handed threads. The blade pitch and direction will not change by simply flipping the blade
love how you used the OEM fan control module with factory connectors at the fans....its clean no switch to worry about.....using the factory module could you have wired in a manual override in case you wanted them on all all times?
I really enjoyed this video brother. Keep up this style of content.
As always a clean, tidy job. Couldn't expect no less from you. Love your channel.
PlqlL
So clever. I'm going to do this when I get my new set up!
I'm not a pro but with connectors I always make the female the always hot and male the receiving side. It just seems like an extra safety precaution if u forget to remove the fuse when the fan is unplugged for example

Not sure if you still check and reply to this video but I had a question I was hoping you could answer.
I wired my fans exactly as you did. When I jump the pins I can get speed 1 to work but if I jump the 2nd set the other fan does not run. I checked for voltage between the temp switch and the plug on the FCM and found 12v when the 1st set of pins are jumped but nothing when the 2nd set are jumped. Only thing I can come up with is a break in the wire somewhere but was wondering if I may be missing something. The ac has been removed from the car if that matters.
Nice instructional. I have a puller radiator fan and a pusher ac condenser fan . Should i wire them to come on together or separately?
I might have to try this setup. I've got a mk2 Jetta 12V VR6 swap with a Corrado SLC radiator and fans. In the middle of the Texas summers I have instances where my water temps get a little too high for my liking. Just to pick your brain... Did you custom fab that fan shroud or does somebody offer it for sale? What electric fans are you running?
Wires and old plugs I have are 4 wires coming out of each fan. Not sure where to put the 2 wires into the 4 wire plug. 🤔 yellow, green, and black and blue
So in this particular video, yuo are basiclly using the PCM, and or the relay from the factory setup/fuse box? I'm asking becouse the high speed fan on my 2005 Mitsubishi Endever, has a fan controle modle pluged directly into the fan motor! Unlike the two separate wire hanesses. Thank in much in advance!
Clean job i really appreciate it
Okie so I'm watching the video still but I have a question if I bought a universal radiator fan for my car could I hook it to the old fans connections on the car already?
Ran my wiring and they won’t stop getting hot so I’m searching these videos for help lmao
HI, Charles, I have a problem and I don't know if you cover it before, The problem is I add a new fan on my transmission cooler radiator and I install on/off switch but sometimes I forget to switch it off then when I come back the car battery is empty
What brand of fans are you using? Looking for some and there are just so meany brands hard to tell witch ones are good or better or best.. So thought I’d ask you what brand is your go to brand..
Hello I have a 1987 mercedes 300d. I want to get rid of the clutch fan and add a fan set up like you have. I live in boise area and it hits over 100f often.
And my car will run close to red if I run ac. If I paid you and gave you the factory wiring diagram could you draw out how to wire it in so it will work.
Im not sure how to wire it to the factory temp switch. Any help would be greatly appreciated and I'm more than happy to cover your time. Shops in my area are afraid to work on a mercedes. Thank you for your time. Robert
Good morning with that setup when 2nd and 3rd speed kicks in are two fans working or just one?
I have the same question. In the video just before this he made a wiring diagram, but it is different than this setup here, so i dont know why he had the diagram one way, and installed it a different. To get one fan on low, and 2 fans on high. Take the low signal from the thermostat, before it goes to the fcm, and take the high setting from the high setting on the fan harness, after the fcm. You should still have ac, after run, and the system working a vw intended. This is how he made his diagram, but didnt wire it this way for some reason.
Can both fan run on one modul unit
I followed this video to install 2 mishimoto fans on my mark3 GTI. However, I do not have a shroud. The fans operate perfectly but they don’t provide enough airflow. Car didn’t overheat but it got very hot during the first drive. Where did you get the shroud you are using? And how did you mount the fans?
whats the tool you have to remove the pins?
thanks this help me turn my push fans into pull which i needed to do for my setup
Awesome
Wow, nice job... For some reason I was expecting cheap non-shrink crimps, exposed wire, etc.
+xephael - oh man. That hurts my feeling. lol
HumbleMechanic sorry I've seen too many butchered electrical videos on TH-cam. Shocking when you see someone do a good job!
HAHA Thanks. This is an area I am kinda fussy about. :)
did you have to run a big fuse or get a higher output alternator to do this ? I have a 65 dodge dart I'm setting the car up for street and strip. I want to do this on my stock 82 dosge truck .i think my alternators put out 120 or 130 amps?
i want the both fans to run on high speed all time on my Suburban 2012 because my country is very hot specially in summer and overheating when stopped on traffic signals so I want to run the both of them in high speed situation all time by 4 relays 5 pins and a breaker saftey fuse 80 amper can you draw the diagram thanks in advance .
Thank you
Can I connect one high speed home fan thru an inventor instead !!!
How would I do the same fan to just a toggle switch? I have a black and blue wire on the fan, and a three prong toggle switch. Just want to be able to turn the fan in when it needs it and off when cool.
What size fans should I run for an Obs chevy truck with a 350
can this 12v or 24v fan be powered by a power adapter like 5amp powerbrick? would it even spin? how loud would it be and how many rpms would it spin? thanks for your estimated knowledge.
Nice video, I have a 2007 Passat 2.0 FSI, cooling fans are NOT working properly, they come on when I applied power with a battery to plug, they do not work period when car runs , nothing when a/ c is turned on, I've replaced thermostat , coolant sensor, checked fuse, unable to locate the fan relay, any ideas?
How do you wire a warning light in to tell if the fans are running
Why are crimp connectors the preferred way? I've always used solder and heat shrink as it seems the be the strongest, most reliable means of connecting wires.
Charles Hollow I have the same question. Especially on smaller wires. I do an axial twist, solder, shrink, seal and wrap.
I heard that solder can break after a while due to exposure to heating and cooling quite often. I guess it depends on what solder you use and how much and the quality of the wire. Crimp connectors are much easier and less time consuming way of fixing a connection imo.
+InsideOfMyOwnMind I’ve seen testing that proves either one can be stronger than a wire.
The big key is “performed properly”.
www.hpacademy.com/technical-articles/solder-vs-crimping/
"Correctly applied, a solder joint can be strong and offer good conductivity, but a solder joint is also brittle and is prone to failure under continual vibration - Exactly the conditions we can expect in the harsh motorsport environment. This is why we avoid solder joints at all cost in situations where reliability is critical."
And in my opinion, tracing wire defects is the last thing you want to be doing..
I learned a lot! Off to hf to get a heat gun!
What amp alternator are you using? I'm thinking of doing an electric fan swap on my 88 Ford Mustang 5.0L V8. It has the 135 Amp alt. on it already.
I have dual speed fans and three wire to both fans, trying to figure out how to wire similar fan set up 2003 golf
Nissens Danmark ^^ So fun to see something from my country in this vid. I have a buddy that use to work for Nissens.
My spal fans keep melting apart at solder joints where it goes into the motor wtf any suggestions?
Are this from grayfabrication ?
Great job thank you
how do you wire a 3prong led rocker to ground? two wires, no relay. when its off it is illuminated. when its on, not illuminated. reference, "Ford 6.0 blue wire mod" for the engine cooling fan over ride. I've had it hooked up before and now i cant get it to do what it did previously :o(
Does the butt connector that you use have a adhesive in it when you shrink it?
Great video. Can I do it that way in 2012 Kia Sorento 3.5L v6 with a single fan? I want to install a flex a lite fan on it.
Why would you want to change the fan?
Can i use this method on my 2008 bmw 535i ? Theres a loud noise it makes when i turn it on , in not sure if its the radiator , clutch , or cooling fan ? Advice would be appreciated
I was just reading an article on crimping versus soldering.
It seems the Aviation industry is against soldering and repairs must be crimped.
Mainly possible heat melting the solder and or corrosion damaging the soldered connections
Brad Downs I am curious what is the corrosion catalyst of a connection soldered with rosin flux if both types are sealed? I'm not challenging your comment but am interested in the knowledge. I have not seen a properly sealed solder connection corrode unless it was faulty to begin with causing excess heating and sealant failure, something that crimps are also subject to. Heat matters due to the hydroscopic nature of the cooling process.
Continious vibration weak solder joints.
InsideOfMyOwnMind
They really didn't state the reason for corrosion but I would imagine the environment of the aircraft has alot to do with it.
Please cite the FAA/MIL circular publication ID, chapter and section that show explicit warnings and or prohibition of solder joints and or soldering connections/connectors.
In FAA publications Aircraft EWIS Practices Job Aid 2.0 and Advisory Circulars AC43.13-1B/2B, 43.18 wiring fabrication, repair, connector soldering procedures are described, no where in the publications is soldering prohibited, limited or warned against.
Where can i find those connectors??
Hi sir
What happened if I connect two fan in a radiator in a key switch on
And the two fan running comsistently when the key is on
Is it safe and advisable or not?
Im just confused because i had a chevrolet optra and when the thermostat ac fan off the reservoir are overflowing and when the thermostat ac fan on it becomes normal
So I bring the car in the autoshop and they do the two fan connect as one so its run when the key is on and now my reservoir are normal and my car run smoothly so i just want to ask an advice of this setup of mine thanks
Godbless
What kind of fans are those ?
How much CFM ?
Do you have a link ?
What's that tool that you use to slice through the loom? Cool video.
It's a seam ripper. It's a sewing tool.
What cooling fan shroud is that and would it work with a mkiv R32?
Did you bypass the coolant fan module
Where did you get the connecters
What type of fans are those and where can they be ordered?
+Kelvin Fuller the are Mishimoto fans. I got them from a buddy so I don’t have a recommendation for a source
I am in the middle of replacing my fans, can you tell me if your fans are 12" and the cfm ?
These are the same fans and shroud (swoopsbuilt) I'm running on my car - they are 12" Mishimoto slim fans, 1150 CFM each.
I like your show i like your music
Thank you!
What an outstanding teaching video, Charles. I have been waiting quite some time for such a stellar video - one that is clear, steady, informative, and helpful.
One question: what brand terminal release tool did you use? I am struggling to find the correct tool for my TCM harness unit.
Thank you, Charles.
Michelle
+Michelle E. Hey Michelle. Thanks for the kind words. Years ago I bought the real deal VW special tool wire pin tool. It’s the best out there and about $50 each. Ouch!
$50/each is a steal, if it protects your pin. What brand, if you don't mind? I need the specific one you used to fix my TCM wiring harness.
Unless I'm missing something, wouldn't it make more sense to Have 1 fan for speed one, the other for two, and both for 3?
There would really be little difference between one and two that way.
@5:45 what wires you slicing into?
Have a 84 cutlass
hello
i need help if you can
i have 2003 ford f150 4.2L i bought VW touareg 2010 electric fan with speed controller module how can i fix it with the module benefits, what parts i need to add or cancel in my truck what the connection diagram please help
Hello, I was wondering if I wired my fans like this on my mk4 Jetta would my ac still work
Hey Charles would this be the same on a mk6 gti? I know the fcm is on the big fan and I would like to keep it if possible but would like to put in a set of mishimoto slims like you've got as I'm running as high as 220 degrees on my coolant sometimes with living here in south Florida. Thanks in advance for the help.
You should be able to wire them similarly. It depends on how your fan setup needs to work.
I picked up a Ford Contour V6 dual fan setup that I want to re-purpose in my Camaro. The fans are 2-speed, and each fan has a separate connector with a 2-wire pigtail. Supposedly, one wire is for low speed, the other for high speed. But there's no ground wire. How do I test these fans and hook them up?
They have to ground some how. Can you get ahold of the wiring diagram for the fansb
Do need to upgrade your alternator after installing two fans
No they shouldn’t be an issue
Was that coolent temperature sencer how you jumped the fans ???
No the thermal switch
@@HumbleMechanic thank you
Can you please tell me what kind of tool are you using at 5:47 to open up the OEM harness?
It's a seam ripper used in the sewing industry
@@PWgadgets Thank you friend
moin Abu Dhabi my Mazda 6 2009 not wiring fan . only cooling working with A/C.In Abu DHABI outside 43C
Español por favor..y te faltó como van conectado los relex.para que te quedará completo el vídeo.y que dará la enseñanza completa.
Awesome video. Can I also do the same wiring for my ford escort?
Sorry. Didn't see the different dies. Not familiar with Sonic crimpers.
Single, not double crimps for heat shrink. Still feel bad.
I need to do that too
Great video!
What tape is this called? I know it’s not electric tape.
www.amazon.com/tesa-tape/s?k=tesa+tape
@@klubstompers thank you.
Piece of advice Mishimoto fans are junk fans.Spal really is the best to use as they have the highest CFM compared to Mishimoto.CFM IS CRUCIAL TO COOLING A ENGINE ON A HOT DAY
had a question about my cooling fans. do u have an email or somewhere i can message you?
Your best bet is posting here. Someone else may have the answer too. The collective is WAY smarter than I am. Lol
Mishimoto is garbage compared to Spal....Check out the FRS video from LHT Performance. It's pretty clear that the Mishimoto is sub-par.
❤❤
Load side should have the MALE pins to help avoid boo boos while the connectors are not connected.
+ycmdill that’s good advice for sure.
I’m just trying to picture the series of events that would have to happen for this to really be an issue.
Not saying you would do it but had a helper while in the AC business. Left an ohm meter across the compressor to see when the thermal overload closed and went into the house for a moment with the 220 disconnect open. Came back to a familiar (smoke out) smell. He plugged in the disconnect while I was gone. No reason.
need advice for my Audi 5000 Turbo..radiator fan..
Okay.
💯👌🏽
Relays are bad news for starting DC Fan motors from a dead stop. It can also blow the diodes in your alternator. Much better to go with Pulse Width Modulation type of controller. Relays will fail over time and burn out. www.autocoolguy.com
عمل ممتاز good jop
Why wouldnt you just find comparable male female plugs do you spices onto new pins avoiding most if not all splices. I hate splices like a plague. Hate them about as much as VWs fan control module.
You're using the wrong crimpers
Yeah, sorry pal I couldn't make any sense out of this video, I just saw you cutting and head shrinking wires.
I shot a theory video too that may help.
Lost interest in this video with the set of ads popping up. What a concentration breaker
We sell higher wattage electric fans than those in this video at www.americanvolt.com/collections/electric-fans which includes radiator mounting kits. Various thermostat switch turn-on temps and NPT thread-in sizes available as well.
This video did not help me
Sorry about that.
You talk to much i only meed to see it done thank you
Your computer and TH-cam come with "TWO" ways to lower the volume, if you find the host is talking "TOO" much. You are welcome "TO" adjust either volume control at any time. (I hope this helps ..thank you)
Is this guy an Aaron wannabe ???
you talk too much wasting everybody's time
You post too much, wasting everyone's time.
Wrong crimpers for that connector. You should know better dude.
+J Doe which ones are the “right” ones?
HumbleMechanic they have to say snap-on....lol
HAHAHAHA
Next up is getting the AC all worked out. I am convinced that the AC compressor is toast.
Shoot. Sounds like an expensive run to the parts store. Good luck :)
HumbleMechanic
On a totally unrelated note....
I now your a vw guru so ....
Why dont vw/audi 3 cilinder engine,s lay exactly horizontal ? Im dying to now .... thx up front
+TheMatrixcube hummm. I am not sure. US never got the 3cyl
HumbleMechanic
Dammit nobody seems to now ...
+TheMatrixcube I’m gonna do some research because now I’m curious
Charles hi you are the best.I realy love the way that you work and your nolege.I have a question and I want your help.I want to make an electric fan conversion to my audi a4 aeb engine.I know all the wiring and mounting but Im puzzled about the location of the fan switch.Must be on the inlet or in outlet or the radiator?Top or bottom hose?Please I need you professional opinion.Thanks a lot.
have to put aftermarket fans in my 97 jetta after its previous owner hit a deer and this tutorial made the process a little less daunting! it may be 4 years old but it definitely helped me
What connectors did you use to link the fan harness to the cars main harness?
I would like to know as well
Just curious but shouldn't you test the fans before shrinking and wrapping up the wires?
Hey Humble Mechanic. Where would you put the thermocouple sensor in a vehicle that didn't have electronic fans. Would you put it where the standard temp gauge is or at the top or bottom radiator hose or at the thermostat or somewhere else? Thanks
What if you have black with yellow wires meaning neg and blue with green wires meaning blue and I’m trying to connect them to the black and blue for my fan -literally kinda like yours????serious HELP!!!
Excellent use of a seam ripper :) Now I know what to do with my extras!
I wanted to add a small cooling fan to my engine hood to cool off the engine bay. I by no means have a racing 1999 honda crv, but I wanted to cut a small hole on my hood to allow the fan to pull out the hot air from the engine bay. How would I hook it up to the electric?
