IMO on older cars going from a power robbing fan to an electric is one of the best things that you can do. Warms up a bit faster, cools better in traffic, frees up more power that was being wasted by that stock fan, and uses less fuel overall.
agreed
Stepside1986 I had two electric fans on mine.....it overheated and drained my battery 80 watts each they pulled. I went back to a flex fan...I could careless about 20hp loss. My car is around 500hp big deal I hated electric
Michel Linschoten when you have 2400cc 5-10 hp can be 10+% of over all BHP. So suck it elitest.
Michel Linschoten I tried it too but just one fan and I had the same problems with the stock parts but I’m willing to try it again but with my Dodge Charger and a more powerful 320A alternator / upgraded power supply

It sounds like you should have had a professional install it for you.
You can reverse the polarity going to the fan to change the blow direction (push/pull).
I did the same conversion on my Silverado
Very satisfied
Good information
Awesome..glad you liked the video..dont forget to subscribe :)
great detailed work, you showed every step. good job.
+Spacefied thanks for watching
It gives you more power because when you rev the engine to high RPM it can spin easier. Therefore, less force going in the opposite direction of the force of the rotating assembly. Its lighter without the fan too. You need a fan when your not moving like in traffic so why run a mechanical fan all the time when your moving all the time and the wind is naturally cooling the radiator. You also don't have to worry about getting stuff caught in the fan when your working on an engine at idle. You also get more room in the engine compartment because the mechanical fan is not in the way anymore. It also make your engine sound different because you don't have the constant loud sound of turbulence from the mechanical fan. I have dual electric fans on my 72 gmc truck with 350. I took the electric fans off of some newer dodge van for free and built some brackets and then got a controller for $30 on summit. And it has been working for like three years. It's easy to install there are like two wires, positive and negative.
This is why there are clutch fans. This fan install just misses the air OUTSIDE the fan frame, but inside the shroud . I am happy the original fan shroud was used. 20-30 amps is a drain on the alterntor which sucks horsepower as well. This amount can be equal to any gains. IT was Not done on 3/4 ton trucks for a long long time later. The only reason GM went to Electric fans was space. They were a big warranty headache with hotter engine temps being required for emissions as transmissions burned up when over 200 degrees
That would be because with no belt your water pump is not working.....
It doesn't really "give" power it moreso "frees" power especially at high rpm
Could have really used these videos back in the day. First time doing this is always a problem.
If this klown can do it..so can u :)
The only problem that is not discussed in any of these CZcams videos is
that your factory fan clutch ties into your vehicles PCM, at least it
does for the Chevrolet/GM line. So, when you do the
Delete/Replacement/Swapout to an electric fan setup, your vehicle will
report back to your PCM as a failure or Check Engine light event, making
it impossible to pass a state inspection in the future.
These don't have computers😂😂
I think it would be better if the gaps on the sides of the fan were covered up to the shroud itself. I think that would significantly improve the efficiency of the cooling.
Car runs very cool..thanks for watching and commenting
This is what I'd rather be watching.
Thank you
Very professional. Better than some car factory installs.
thank u
my factory service manual hid in very fine print that the engine driven cooling fan on a 1996 chevy LT1 with trailer towing package consumed TEN HP
Lol that's funny
I have a '79 Z28 I am going to do this someday, but for now I need to put one on a 4x4 truck. I do a lot of slow driving over rough terrain and the AC stops working and the engine overheats with the stock fan. I never liked the idea of zip tying the fan directly to the radiator for fear of springing a leak in the boonies. Making my own brackets like you did is the way to go.Thanks for the video.
thanks for watching and commenting
Screw 195 turn on with a 170 off point. That's 25deg difference the fan will be running like crazy and ping off the line . A cheap capillary switch with the probe in the upper hose or pushed through the rad core will be way better. Mine is set to come on at 175 and it turns off at 170.
no issues with this setup at all..thanks for watching
The way it should be when going electric....
There are 4 part numbers listed in the description. Do you need all 4 or are these different options?
I am planning to install an electric fan on my 2001 Toyota hiace shark 5L, hope it's gonna work nicely.
Properly working clutch fan doesnt draw much HP at speed, electric fans put a load on the alternator and turn on at a certain temp and run until the temp drops unless you put in a switch. So unless they are off at speed you wont really see any HP gain.
Cool thx bro, will be installing one on my chevelle 👍🏻

Nice job, looks pretty straightforward. Only wish you had done it in the day light. For me it was a little tricky to see at times

Dude you are a National treasure, your videos have save my ass so many times with my car (profile pic). So shine on you crazy diamond n keep the videos coming
Awesome! Nice car! Glad I was able to help you out!
What about the gap between the edge of the electric fan shroud and the original shroud? Seems like air is just going to slip through that gap. Why not shield or close that gap with some heat-resistant rubber or other material? I like your custom bracket technique.
Thank you..closing the air gaps is a good idea..don't forget to subscribe
haha. good video. doing the same thing to my 81 camaro right now. trying to figure out where to mount my circuit breakers and relays..
Thanks brotha, I e been looking for an actual install video for this for ever. My electrical skills are shyt lol
working on my 98 wrangler.
U got it..good luck
10/23/16 thanks for the help I just installed a electric fan using the same shroud for my 1979 Camaro z28. I'll probably install the relays this week or weekend.
Awesome. .glad i was able to help
All that thread sealer is going to create resistance and give a misreading.
nice por la van nice klowny I gotta do that to my lady's 64 ss been sitting garaged for month's now but I tuned it up it's og carnal but it over heat's I hope this method of yours will do the trick!!!! thank you carnal for sharing...

Great video I learned a lot. Why did you switch to white color instead of keeping it yellow.
Thank you..not sure what I switched to yellow? I work on alot of cars..was it wires? Maybe I ran out

hey..lol nah this was last weekend..weather was gorgeous today..2morrow i have another car im doing..thanks again for watching
Where did you get the battery spade connector haven't seen them before.
Great video. Thanks . my 80 berlinetta came out great. I did exactly what you did. I musta watched this video friggin 90 times. :)
Awesome..glad I was able to help u out
Everything in detail. Great video. Good job!!!
thank u
Damn! That is a nice install! Makes me want to buy another Camaro. My 88 IROC had dual fans. I think I like the 84 Z28 Style more now. One thing though, you forgot to use your special Klown Lube when you drilled the holes in the flat stock.
good point abt the klown lube..sorry i failed u ..wont happen again

Awesome thanks for watching
Manny you do excellent work 👍👍
+Steve Rob Thank you sir!!
Thank you for the video, I must have missed it but what year and size electric fan is that from?
James Grant it's from a single fan thirdgen camaro..u can use a 91 camaro fan
Hey Klowny! Great video! What size is the fan? I'm going to try this on my 78 Camaro.
Great video nice work.
I would have used nylon lock nuts and it does look stock. 💯👍🏼
Xavier Xavier thanks for watching and commenting
nylon lock nuts stronger enough in long run ? or temporarily for short term ?
SUN NETOR I’m just saying lock nuts won’t come off with the vibration of the fan and he also has a back up fan if this one shells out.
Did the conversion on my 1992 MB W124 but with a 2-speed fan to keep coolant temp as stable non fluctuating as possible and to have less noise and power drain on the only 115A alternator, and there was already an auxiliary pusher fan for the AC.
What is the alternator's rating? Some claim not even 150A was enough for a good electric fan conversion.
The amp rating on the alternator depends on the car and what it originally came with.
@@klowny1969
I was wondering if you used the stock or replaced it with one of higher output since the conversion involves extra electricity needs to the system. I'm under the impression the stock alternator is just a little better enough for the stock car specs that did not utilize an electric engine fan. My stock was 90A actually.
Thanks for vid. Do u feel a difference in power. I've heard 5-20hp. Your thoughts?
Looks nice and factory to me. Good job.
Thank u
AWESOME VIDEO. I learnt something and just wanted to say GREAT JOB
Lauren Siemens cool thanks
What was the thermosensor you used😊
I think I mentioned in the video what thermoswitch? No? Don't forget to subscribe 😉
No you didnt
Thanks a lot MR. klowmy 1969
I think I may need a stronger fan.
Jose Mercado you got it..i hear ford taurus fans are very strong
You make good videos, it shows every part of the progression and detailed verbal explanation of what your doing and why.. Just curious do you know the manufacturer of the anvil/vise your using. I would like to get my hands on a heavy duty one like you have. Thank you
wilton makes the vise..thanks for watching and commenting
interesting does the original mechanical thermostat need to remain in place when converting?
And the alternator drag from the electric fans voids the power gain when on.
not true..dyno results beg to differ..dont forget to subscribe
@@klowny1969 dyno with the fans running?
@@Watchout1010 depends on what mechanical fan you have but Engine Masters did dyno testing on this on a 500hp engine and showed a loss of about 3hp from the alt draw but a gain of between about 10-30hp depending on the fan. 30hp gain from ditching the stock clutchless 7 blade fan like on a 60's or 70's car.
Great video! Did you have to get a stronger alternator to cope with the fans extra amp draw?
we did put a bigger alternator in this car later on because we added alot of other stuff..dont forget to subscribe
thanks man. this was a very good video
exactly what i was looking for.
Alonso Majikal glad i was able to help
You have done a great job and detailing thanks. what about your AC wiring
Thanks..i installed a vintage air in this car..if not u need a different relay with two wires to energize it
How has this setup survived over the years
i have a 1990 Chevy c1500 4.3 I'm trying to find my ignition wire I don't know where it is or what color it is any suggestions
Do you have a video on changing out a starter on 2006-2008 Chevy Impala?
not yet
Hey buddy, I have a huge favor. Do you think you can draw exactly how to wire all those wires? I need to put one of my 67 camaro.
Check out my video on installing dual fans..I drew a diagram in that video
@@klowny1969 thank you sir
Instead of installing the thermo switch to the intake manifold can it be put on the side of the engine block as well?
Cortez P yes
I don't know too terribly much about cars, but I'm very interested in learning more. Am I correct in my assessment that all this really does is take away a relatively small amount of rotating mass, leading to a bit better throttle response? Could you eliminate that pulley altogether removing even more rotating mass with a different length serpentine belt, or at the least, replace that pulley with a lighter aluminum one to add to the effect similar to kits I've seen that use differently sized pulleys on like the AC compressor to reduce parasitic drain. Just curious, I just found your channel tonight and subscribed, you seem to be very in depth and I'm always interested in learning new things.
this particular engine, u cannot get rid of the pulley because it runs the water pump..unless u put in an electric water pump..lighter pulley wont do much..an underdrive pulley will give u a little more power..but then ur charging and cooling can suffer a bit
klowny1969 Thanks for the response. Am I correct though, that really all you will notice from this is maybe a slight increase in throttle response?
+boomstick900 yeah that and some added hp
Show us how to wire a hei 4pin distributor keep up great vids
nice i want to do that to my caprice statesman 2006 ltz V6 but the problem that is no space betwen engin and the radiator so tight
u can install a thin fan..check summit racing .com ...thanks for watching
thanks ..
my car drives me crazy i think i am gona set it on fire
Great video may ask where u got wiring kit thank you bro
Thanks..summitracing or jegs
you are totally awesome sir. this is a great idea. i love your cars.
Thank u sir
Part number for fan??
And do you think a new aluminum radiator is worth them money versus a new OEM radiator? I'm looking at a 3 row mishimoto radiator, but I don't know if the stock shroud will fit.
Mark Hodge if ur planning on putting more power into the car or the car runs a little hot. .then i would go with aluminum..i dont remember how big that thirdgen fan is..but its a beast for a second gen
Thank you great klown master!
what mini blow torch did you use?
My fan came with nylon straps to put through the radiator cooling fins but I like the shroud idea. So, you can tap off the choke wire? How convienient. Got it to do tomorrow.
Christopher Wyller wait..what are u tapping off the choke wire?
The yellow wire off the relay to the thermostat switch then from the switch to the choke wire. Switched 12v from the ignition switch. Using a "Derale" relay and harness kit.
Christopher Wyller as long as u put it on the "switch" side of the relay
There's a yellow as well as a green wire for a manual ovveride. Looks like that activates the relay. At least I got all night to figure it out.
So I did it today and got it done before dark. So, it does work but it heats up to 200 before the fan kicks on and off keeping the temp at 200. Either my temp gauge is off or the sender or coolant probe is faulty. Luckily I saved the fan and shroud. Gonna drive it a few days. It's so stinking cold now with the heater going all the time I don't think it will be a problem until summer. All I think i'll hafta do is get a better fan assemby with some kind of a shroud. I think i'll put in a manual ovveride switch so I can turn the thing on when I want.
What car did the electric fan come out of?
1991 camaro ..thanks for watching
Hey Mr. Quick question what temperature thermostat did you put I put the exact same set up you have just wondering about the thermostat
Jose Mercado i always use 180 on every car i work on
What size fan
Do you have any videos on the dual fan setup for a 3rd gen, I have a 85 camaro that came without electric fans, I bought the dual fans from an 87 or 88 off eBay but I'm confused how to hook the harness up because theirs nothing to plug into on my car that would power them
austin C its similar to what i did in this vid..get a dual fan relay kit..there are also instructions in the kit
Is it true, that by simply installing an electric fan you can increase Horse power?.
Yes..less parasitic drag from the engine
Thank you,, I loved this video, (very well explained)
Thank you
@@klowny1969 Is the HP increase actually noticeable when you drive it?
thanks for the video does the 12v source have to be live all the time or one the turn on and off with the key switch like the radio fuse?
U can wire it both ways..i like switched 12v..thanks for watching and commenting
+riuuku - Ignition Fuse or Radio, less switches and less money :))). Just tap into those wires or tap into Fuse Box itself :)))
@@JodBronson like the fuse box idea... then just toss the appropriate fuse. I dig it dude.
from the realy numbers what is each number connected to? I'm having trouble wiring the efans on 98 5.7 vortec
Amado Aguilar check out my channel on how a relay works ..thanks for watching
so the pully for the old fan stays in the belt? does anyone take the pully out or is it just the weight of the fan itself your taking out of the picture?
Caleb Spurlin u need the pulley there for the water pump..just take the fan off
Why is there 2 wires going to temp switch on intake? My truck only has one.
Monse Bishop it can be two or one..if its one, the one wire gets grounded by the switch..if its two its usually because it acts like a switch between the two wires
Nevèr paint the fan blade..can throw it off balance
Great job! Great video!

I upgraded my electric fans and now they're draining the battery. Any ideas?
What's your voltage when the fans are running and your engine is running? It could be your alternator needs upgrading..don't forget to subscribe
@@klowny1969 I'm not sure. I built the engine and dropped it in...but im not an electrical guy. I was driving it and it got hot so I stopped and noticed the fans were not on but should've been and i cut it off. Then I put the key in and turned it to on and the fans came on. Went to start the car and it just made a single click noise. 20 min on a trickle charger and it fired right up.
And I just subscribed! Watched a few of your videos as I'm doing a 91 Camaro.
what's the better advantage with electric fan
Bobby Salazar gain some horsepower and free up some space
Doesn't the electric fan create an extra load on the alternator making it
Work hard using horsepower?
Nothing's free
yes you are correct, however dyno results have proven at least a 10hp gain (depending on setup) over a mechanical fan even after taking the extra alternator load into consideration. Don't forget to subscribe!
@@klowny1969 I suppose the engine rpms and the cars speed has alot to do with the fan loads.
Don't clutch fans let it free wheel
At high speeds dropping the power requirements to about zero?
I don't know if the blowers they
Use on the dyno have enough pressure to disconnect the clutch
Like it would at 85mph
@@klowny1969 lol a 10hp gain
My triumph spitfire is only rated at
56hp so that's a pretty big gain

+ابوانس بن هيف thanks for watching
How much hp would u gain if any?
I watch a show called Engine Masters and they dyno tested power robbing accessories. It depends on what fan you're comparing to. But on a 500hp motor they gained 30hp over a stock 7 blade clutchless fan! That was the biggest gain they had. Clutch fan robbed around 18hp if I remember right. They also tested various aftermarket flex fans.
what tool did u use to read the temperature of the Engine @Klowny1969
Infrared thermometer
Dose this affect ur ac at all I added the electric, fans now when I turn on my ac my voltage goes really low
Amperage problem, get a battery with at 800 cold crank amps and a good alternator
What way is the air pushing towards?
It's a puller fan, they are more efficient
Thanks for video brother
thnx for watching
no lock washers???
