Electric Fan Install on a Hot Rod (Step By Step)

[@trailerparkcryptoking5213]

You covered almost everything very well! You left out one crucial piece that is extremely key in the system! Electric fans pull a lot of amps and because of that you need to be sure that where you tap in to a power source for the fan motor that you are getting all the amps needed to run the fan. Check your wire size all the way from the alternator to the battery to be certain it will carry the full amperage load that the alternator produces. If your alternator wire runs to a junction, it’s possible that a smaller wire runs from the junction to the battery just big enough to keep it charged, meanwhile the junction delivers the rest of the amps to the rest of the electrical system. If that’s the case then tap your fan power wire from circuit breaker into the junction or size up the wire from the junction to the battery and for that matter if you have a high amp alternator you should size up the entire wire from the alternator all the way to the junction and then to the battery, probably 8 or 6 gauge, there is a chart online that gives the proper wire size for your amp output of the alternator...... This is extremely important for the reliability of the entire electrical system! Great video!

i just wired my first fan relay on my 68 chevy II and this video is awesome... i watched at least 20 other videos before installing and all of them had bits of good info but George made it simple and cleanly explained... i wish i would have found this video 1st... i could have skipped the 19 other videos i watched!!!! thanks for the video... keep hot rodding brother!

[@mikewolfe3140]

It thought he explained it pretty well

[@eugenejankowski9977]

I want to tell you your video is exactly what I was looking for. I'm not great with the electrical side of vehicles and with the help of your vid I feel confident wiring a fan on my project. Thanks man

[@georgesspot]

Thats great man 👍, i made the video help people out and it looks like its doing a pretty good job, good luck with your project 😎

[@eugenejankowski9977]

Me and my son are swaping a straight 6 for a 305 on a 53 chevy 4 door. One of the issues we faced is the room for the clutch fan. So thanks for your help

[@jameswalton4563]

Thanks for the info simple and clean hook-up . I have two fans, second fan I tied in-line with fan 1 with a toggle switch. Flip it on when towing or any excessive work-load. Thanks again!

[@PeterMorton-g1i]

I have brought a 100amp 12volt relay & have installed for the 12Volt Toilet for my 6.20 Fiberglass Cabin boat & it works perfectly & this can run on the house 12volt battery once the battery has been charged with the F150 Yamaha 4 Stroke Outboard Motor & when some wants to use the toilet no problem at all as just open the 2 valves & close the privacy cover & then the person can go to the toilet no problem at all & having that 100Amp Relay makes a big difference use less power to operate it & Relays are really good if you to power 12Volt items Kind Regards Peter 😊

Thank you for that video that was explained really well nice and simple watching from the UK

[@Jonathan.548]

Thank you Brother, I putting cooling fans on my 70 F'100 I'm glad I found this. the freaking sending unit and 85 now I get it. Thank You

[@hywaychild5411]

Hey George thanks for the help I'm fixing to do a install my self you made it look simple . I did want to say one thing and i hope it's not to late LOSE the fancy gas filter there are the cause of more hot rod fires then any other ting . they are notorious for leaking and catching fire !! hope you believe me and remove it before it is to late and thanks again for the help

[@flexmarchetti]

Great job showing these steps,very helpful, thank you

[@sierraridgereaper]

Nice clean install... only suggestion Id make, swap out that glass fuel filter. They vibrate and break and your fuel pump sprays fuel on those hot headers its all over. They are a serious fire hazard... 😉

[@bulldogstrut1]

Great video. I am curious if you covered the exposed hot leads at the circuit breaker. You wouldn't want a short circuit to occur.

[@RG-od4jk]

Were do you put the fan wire in the fuse box? And can you still keep and toggle switch hooked up just in case the relay goes out. So you could override to keep the fan going.

[@RobertSiwik1968]

Good video, just so you know that relay amp rating just means it can handle 60A you could have used it with no problem. But the pigtail wiring looked thin , good idea to run your own wire to the relay.

[@shoe2241]

best video i have watched !!!!! great job.

[@georgesspot]

Thanks a really appreciate it glad it could help out some people 😁

[@TheHortond]

I love your video. Your attention to detail is as it should be. I would suggest a wire cover for your wires. Sometime down the road.

[@jodaddysdodgegarage3533]

Nice straightforward piece. 👍

[@minimoe2008]

Thank you for posting your experience. I'm not an electrician but my classic mini has an overheating problem when at idle for more than 5 mins. This seems to be the same kit I got.

[@1965themhs]

Hi. If you take a 30Amps switch and you connect the one end to the positive cable of the fan (12v+) with a cheat connection spade and the other after the fuse box's fan fuse, you will have the same result. For having one way flow of the current you can put a diode to isolate the back flow when the fan starts from the factory's 100 degrees thermostatic valve. For having a signal of the fan's operation, the switch should have a bulb for connecting the positive cable's end of the fan. You will have two separated operations. One with thermostatic valve and one with the switch to operate it manually. On both cases you will see the fan's operation through the bulb which is on when a 12v+ going to the fan.

[@Just1Spark]

Thanks bud. You helped me in the first couple min. My kit (very similar to yours) did not detail WHICH red wire to run to fan (87 or 30). Me not knowing if it could make a diff or not, i wanted to do it right the first. time. And didnt know "brass side is battery side". :) Heres a tip. You can reuse that relay block. To rewire it, just use a small flat head screw driver, and remove the wires/connectors that are inside. Theres special tools you can buy to do that also if need be.

[@georgesspot]

Glad to help out , thanks for the tip too

[@vandettabuilds6641]

Terrific video!! That’s exactly what I needed you covered everything perfect Thank you!!!

[@jasonhastings5538]

Good video !!! Watch those janky fuel filters!! I had one vibrate loose and about burn truck up!

[@petermorton2869]

Hi Sir well done wiring up the electric cooling fan but you should be running an air filter on your carburetor as you get a lot of dust & dirt gets sucked in your engine & can destroy your engine & it is a very nice engine to Please put on a very nice air filter on your engine you don't want to destroy your engine & you can some nice right size air filters for your carburetor & they nice foam filters & will still be able perform well to Kind Regards Peter

[@jesseruiz2337]

I'm trying to rewire my son's 87 Mustangs fan. I will copy your method, it looks simple and clean. The previous owner put in the 5.0 engine and the fan was wired in where he had a switch to turn on the fan near the fuse box by the steering wheel.

[@eduardomontanez700]

Thanks for the detail explanation, would have been better if u used some spilt loom for the the wires

[@richardsmith-qy6vl]

Great job so simple when it comes to wiring I'm a dummy but this is easy thanks for the video I had a 55 chevy truck that was lowered and it had a flip front end I bought it like that but like a dummy I traded it for another truck to tow my race car thanks for the video

Wire #86 the white fan switch that goes to the fuse box. Do I need that wire hooked up?

[@juanpanduro671]

Great video! I watched a lot of videos they just explained the diagram I like how you had wired everything in your truck.

[@brandonamond3124]

Hey George great video . Other videos made it look like rocket science.

[@JuanDominguez-nw8rq]

I love your videos, I like the way you explain everything, I have a question if can help me, if you using a two fan set up can you hook them up in series or with separate relays?

[@alanlarson5363]

Helpful, but let's talk about power, amperage. Let's start with the load, the fan. What is the current of the fan? Mine was 6 Amps. I would design for double the load, 12 Amps in case I need to add a mini fan. The wire and relay would need to be rated at a minimum 15 Amps. So, you do not need monster wiring and relays for such a small load. I purchased the same kit. My intake did not have an extra port so I ordered an adjustable thermostat that mounts into the radiator fins. Also, the thermostat that you installed in the intake just provides the relay a ground point. It doesn't power the relay as you suggested, but completes the circuit. A breakout diagram of the relay, with numbers, may be helpful for others.

[@wrdmndan]

note to self ......not to try wrap wires to any lines running to radiator ....TOO HOT.....OH and switch the ground in paralell to temp sending unit not the battery in other words wire from temp sending unit thru switch to ground .....good job beautiful truck .....just giving my 2 cents as a 40+ years as a control electrician

[@georgesspot]

Awesome glad it helped out 👍

[@Just1Spark]

Heres a tip: If you install this, and the fan wont kick on at temp, loosen the sensor thats screwed into the intake, and see if coolant leaks out. You may have an airpocket in that area. Your engine will over heat long before that air pocket trips that sensor.

[@dflodrummer1]

That's exactly the problem I'm having right now. What's the fix? Just let it leak out a bit to let the air out? The only way I can get the fan to kick on is if I manually ground it.

[@Just1Spark]

@@dflodrummer1 that may be a different issue, but is sure worth a shot.

[@LordAllenFelisilda-nb4og]

where is the circuit breaker link?

[@REVNUMANEWBERN]

I want to put a fan in front of my air cooled Honda 300 I use in HOT Florida to help cool it down, if I DON'T want to use the thermostat switch then HOW would I wire it? I prefer to just use a on & off switch & I will use a separate battery to keep the fan setup separate from the other

[@chunkafunk81]

what a nice guy :)

[@echuckmed5234]

Dude you really helped me out

[@yetituning4859]

Circuit breaker is the same as a fuse. You should also get the same relay amperage as your fan needs. You should return to Amazon and just get the sending unit.

[@georgesspot]

From what I understand once a fuse pops or breaks its done and you have to replace it because it literally melts away the metal in the fuse and will not work anymore ... but with a circuit breaker it can break but it will reset so you dont have to trash it every time it breaks or pops

[@yetituning4859]

@@georgesspot Open this type circuit breaker casing and you'll see its the same thing in a car. Basically in a car its just a case with a fuse. If it was a true circuit breaker you'll see a reset switch or bar. Now thats not to say there are not true circuit breaker for cars. Typically they're use on comp stereos and on the positive lead for batteries on race cars. What you get in these kit are not true circuit breakers. They're a casing with a fuse.

[@Dr0BoI]

Not sure if i missed It but did u put thread tape on the temp sensor?

[@SlanginBeatz]

Can someone speak more on pin 86 ignition wire. What are my options of area to run that wire to. Ive used the interior fuse box "ign"

[@andycandy7747]

When you connected the wire to the fuse box, how did you know what fuse amp to use? Thank you

[@vuze6075]

Did you figure that out?

[@ari1234.]

No leaks on the sensor ..no need for sealant correct?

[@chicoandtheman4112]

Thanks man this video helped a lot but I do have one question on pin 86 is it on with the key off with the key

[@georgesspot]

Ya that wire goes to my electrical fuse box and im pretty sure its a keyed power source and isnt a constant hot wire

[@yosoydpfknr2855]

@@georgesspot ok but if you add a new fuse for that fan how much amp fuse suppose to be? I try to use the 15 amp fuse for the cigarette lighter adding a 10 amp fuse for the fan but blows up the 15 amp cigarette fuse

[@charlespartak2435]

I think id put something over that breaker so nothing contacts the bare terminals.

[@mghenry7540]

Good video well explained. I had to wire my fan. I used the Vintage Air Fan wiring kit, The only thing different is they use the 86 pin for the ground triggers and the 85 for the 12V Key On ignition source which the relay can go either way. the 30 and 87 are the same. I also added a Toggle switch to turn the fan on anytime I wanted. My battery is in the bed so I went from the Starter to keep the wire run short as possible.

[@rob4f258]

Would this work exactly the same for a transmission cooling fan system?

[@robertpaulis439]

Hey George, Really great job in simplistic form. I'm about to install mine on my '89 K3500 Silverado 454 which has some overheating come summer. If you could, would you be a little more specific on the connection in the fuse box cause mine doesn't have any fan fuse in it. Thanks bro. Bob

In you're fuse box just look for a spot with a test light to see if it lights up with the ignition on only

[@frekkledipped]

Why is there a wire coming from the fuse box and another from the battery? Both are power right? Otherwise it seems EZ

[@larrybrown4471]

The battery wire powers the fan and always hot , the one to the fuse box is key activated it powers the relay then when the temp switch makes ground it turns on the fan .

[@davidmckinley5343]

Can I use the starter post for the ignition wire?

[@scottdoubleyou563]

No. It has to be switched 12V. The starter post is constant 12V. You can tap your wiper circuit, or air conditioning 12V at the plug on the compressor. If you run a 5 pin relay w/ 85A, you do both, so that the fan turns on when you turn on your A/C no matter what temp your engine is at.

[@mightysnafu]

Can I connect my temp. Gauge to the sender as well, or do I need a separate one for the gauge?

For gage is a temp sending unit.. for fan it’s temp switch.
