I Deleted the CLUTCH FAN in my Tahoe and it Actually made it FASTER (E-Fan Conversion) 

Love that you went over the wiring portion of this. Maybe I’m the lone geek of the group but I like working on these electrical systems. Making it look oem and tying into the factory system is definitely the way to go 👊

On my wife's 04 Tahoe, I built a long wand out of 1/4" plastic toilet / sink feed line, drilled 20 or so tiny holes all evenly in one side, plugged one end, and hooked up my air gun to it. I lowered it down vertically between rad and A/C cooler forcing air forward through the cooler, a ton of dirt / dust came out and her A/C has stayed blowing cold.

These fans🔥

I did this to my 03 Tahoe LT about 16 yrs ago when i had to change my water pump, best thing i ever did for it lol. Still running strong. Had a guy in queens tune my truck the same time

I wish you had made this video 3 months ago when I did my fan swap. I managed to do it successfully but nobody else has a video as good as this one.

Not into GM at all, but gotta say, this is the best tutorial on how to wiring e-Fans I've come across youtube so far. Kudos to LSXMatt and Tahiti!! Can't wait to see what's coming to both your cars. This put me in a mood to do some mods to my old Ford Tempo.

Feels like forever that I’ve been waiting for this episode!!! Thanks Matt for making such great videos. You’re the reason for my recent purchase of a 2002 Tahoe! Bought Efans when you first hinted at this conversion.

I've been watching most of all your videos on Tahiti! They have helped me out a lot ! Especially the brake upgrade. That was awesome!

Badass man! I’ve been wanting to do this conversion for a while. Really cool that you did the 0-60 tests as well! Awesome results!

I just came across your channel and stumbled upon this build. Watched all of them to now... now I'm subscribed and waiting on the next vids! ABSOLUTELY awesome!

You just made my Friday night. Fridge right here. Gonna pound beers and watch the hell outta this video! You rock, Matt!

I can tell you're a wiring geek like me. Nice job and thanks for including that part. Not boring to me.

The quality of work you do is amazing

An in depth video but this is one of the best videos detailing the conversion from a clutch fan. It’s helpful for me doing one on a 2011 suburban. It’s a 2500 with the 6.0 and clutch fan. I’m 99% complete and the review of the HP tuner was the last bit of OEM info I needed. Thank you!

Been waiting for this one! Good stuff

Thanks for all of your videos bro they are helping me fix up my 2001 GMC Yukon Denali 6.0

Been waiting !! Now time to convert mine.

I'll be tackling my wife's 01 Silverado this week and I am feeling a lot more confident after watching this video, thank you so much Matt!

I just replaced our '05 3500 rad and fan clutch. Amazing AC performance while parked in the heat, so much power drag everywhere else. A manual pusher + Buick 3.8L eFan conversion time! Thanks for the vid!

Awesome video dude this how RU-vid videos should be! Very informative, keep up the good work brotha!

Nice job and a great video! Can't wait to do this to my TBSS.

I'm very glad that you made this video. I am ready to do this conversation on two of my vehicles.

Sir I appreciate your time and effort you put into these videos

Looks like a simple ladder diagram. It's good to see a plan come together like this. Gives me hope.

Going to do this to my 04 SS Silverado. Thank you so much for the how to video. Subscribed 🏁

Thanks for another amazing video.

thanks for this video I been wanting to do this on my 4.8 sierra for the same issue!

Probably best video series I have seen on the beloved ole Yukon’s / Tahoe’s

This is the only way to add an e-fan. Very well done.

Bro you are the Steve Made to car repair. Your videos help me out a 1000 percent

Smart work , thanks for sharing

Good stuff there Matt, thanks.

Awesome shirt man. Ratt is one of my favorite bands 🤟

What a nice clean job you did !

Sweet setup man

Best thing you can do to a non E fan equipped truck!! I did it to my 00 GMC, and 02 Tahoe. Especially here in the desert. Stoplight with A/C going with that crap mechanical was miserable, even when trucks were new, swampy as humid air. It really shined when I pull a water trailer to wet down the tractor truck yard, chill air ( 110 day 55 degrees vent temp) at 3 mph letting the water tank pump spray down the yard. I did have to upgrade the radiator on the GMC as I wanted the tow package radiator. Tahoe came with big rad from factory. I used fans off of 08 6.0 Escalades for both. I did buy the harness from BP Automotive, I also got the optional high pressure switch from them that uses A/C high pressure to kick on fans not just temp. I also added a 300 amp alternator. Your wiring skills are like my brothers, good job. ( Hes retired now from Denver Intl Airport) I did see a 1 MPG increase on the GMC, nothing on the Tahoe.

Thank you for the information provided

Glad the fans worked out, definitely have to do mine. Took at shot in the dark at the local dealer to see if they could unlock fan control while they were programming my master window switch, no dice. have to check the local tuner to see.

Been thinking about doing this

Great work!

Matt! I love your attitude, your superb mechanics skills and knowledge, the clarity in which you teach others, and the fact so far I've never heard a cuss word so my Grandson who's 8 can watch and learn too. You're helping alot of people Brother, especially me, just bought my 3rd Yukon, only have 1 but have owned others in the past but mine has issues. It's a 2000 YUKON 4X4 5.3 SLT, 328,000 but you would never know, it looks clean and nice. My transmission hits hard in 2nd & 3rd, BUT ONLY after highway speeds, 50 mph & over. Then when I start again from a stop once first gear goes into 2nd, it hits hard, then the next gear, 3rd, then the next gear is a smooth transition. NOW HERES THE THING, ANYONE CAN ANSWER BUT I HOPE MATT DOES TOO. When I get off the highway I pull over at the nearest safe spot, shut the truck off for 2 minutes, start it up, goes through all the gears just fine, AS LONG AS I KEEP IT AT AROUND TOWN SPEEDS, UP TO ABOUT 45 MPH seems to be the sweet spot to keep it shifting correctly. HERE'S MY QUESTION: I I replace ALL the Solenoids located under the trans pan do you think that should fix my issue? I already replaced the shift sensor located on the driver's side of the throttle body. Any help would be greatly appreciated...

awesome install video

I love these Tahoe videos I have an 03 Tahoe z71 I been working on

Love how Tahoe/Yukon same in many ways. I had e-fans. I saw no real difference in gas mileage. Stuck with traditional set-up. Nice video

This is the best video I haved seen about E fan on chevy's

Outstanding vid!

That relay box is nice I got just some cheap relay harness things with pig tails and had one or both melt and I had to re run some but I did find some relay sockets that you crimp the actual connections like yours but just individual which I highly recommend and it just makes things cleaner

I appreciate ya Matt, I have a 99 chev tahoe two door that I'm building now and am incorporating pretty much everything you have on yours, your videos are not boring as shit like most

Another great mod! I am not great at wiring & prefer to use the factory harness. Any posdibility you could go over the necessary steps to installing the factory harness? Thanks for sharing all your mods!

LOVE YOUR 80S ROCK T SHIRTS YO ....

Great vid.......lots of details.

You obviously have great taste in music as well !!

Can't wait to do this for mine.

When the beat dropped at 2:50, I thought that beat from spongebob dancing with the jellyfish was gonna start playing 😂😂😂

I fab'ed one of these into the wife's 99 2dr Tahoe. Had to do some creative trimming and mounting but got it in and wired up quite cleanly. I did make a whoops and wired both fans into one relay almost melting the poor thing. Rewired two relays and it works like a dream.

Thank you info 👍👍👍

Be sure to check the temp with a scanner. The stock gauge in these are kinda like a dummy gauge. 185-220ish will sit right around the 210 mark before going over.

Cool videos! 👍🏽

Definitely doing this to my 03 gmc 1500hd.

Your videos are 💯

came for the fan clutch stuff, stayed for the Ratt T-shirt!

video quality is on point now!

Glad you ended up with 10AWG wire, these fans are power hungry. Oh and 10AWG wire is typically only rated to 30A, so you are stretching it a bit with the 40A fuses. Probably fine, but melting wiring is never fun. Bigger wire means less resistance through the wire, and less stress on the relays/fuses. You have to watch out on the cheaper wire, anything under the hood should really be GXL or TXL automotive wire, because it is rated to 125C (257F) and way better suited for under hood temps. Most common off the shelf wire is only good to like 80C (176F). All the factory wiring is either GXL or TXL under the hood, and probably throughout the vehicle really. I skimmed through most of the video but it looks like it was well detailed, this is a very nice resource for this mod. Thanks

Yet another fantastic video! Super Appreciated 😀 👍I can't wait to do the swap once I get all the needed goodies. Question on the Tune what were they able to add over the stock Tune? As I just purchased an 03 Z71 and looking to add as much as possible without replacing headstones, cams etc for Now. Thanks Eddie J. Long Island N.Y

Hey Matt she's looking good man Ur making me want a tahoe

I've been wanting to do this conversion for yrs on my 03 Tahoe. I have all the parts, including the factory harness lol. FYI-- fans up to 2014, are all the same. You def don't want to use an aftermarket harness. They don't hold up. On a really hot day if the electric fans kick on alot, the harness will melt. So if you can grab a factory harness, along with the convenience center with all the relays for the fan, do it. Another thing to think about---you probably have the 130-145 amp alternator, so you might want/need to upgrade to a 160 amp alternator. When those fans kick on they do pull power, and if you have the ac going, along with music, headlights are on etc, your amp gauge will dip. Keep an eye on that shitty Amazon wiring! Def don't want them to melt either. Again--these fans do draw power. Nice vid--again 👍🏻

How does this have dislikes? You are appreciated sir!

I did a Hayden dual fan module,With the Radiator Probe the only thing is fans would over heat it and burn up,So the leads to the fans I threw in a 60amp relay to each fan and haven't had any problems.Great video.

Just about to do mine this weekend good timing. \m/ \m/

Matt you should put fuseable links where your 12v+ tie into you main fuse block lug. Otherwise you have those 2-3 feet of wire un fused. Not a huge risk but for me worth doing.

TIP MY HAT TO YOU..VERY NICE..VERY CLEAN JOB..WILL DO IT YOUR WAY..THANKS FOR THE HELP..WOW..

Thank you for a very well instruction Efan upgrade. I've got everything to make the conversion except someone with HP tuner to help flash the ECU. Can one be rented?

i totally love your shirts.....

I clicked on the video cause the dude was wearing a Ratt shirt, that is fucking awesome!

I got a 2003 chevy tahoe. With 190,000 miles on it. I really Love it. Best vehicle I've bought for awhile. Really comfortable an gets pretty good fuel mileage for being 6800 pounds haha

Hey thanka for doing this video. My clutch fan in my 02 Ranger 4.0 shit the bed. So just get a new fan today, but then seen a lot of videos like this and with mine off I honestly think it's better.

Hey mate any aftermarket wiring harness or kit you would recommend for us not so Electronically inclined, love the video by the way !

I knew the aftermarket harnesses had 3 relays and just assumed it was to run both fans while the A/C was on but now I see you run them in series to get both on a low speed I figured the tune says fan 1 and fan 2 so I figured it didn't matter but I assume that if mine calls for fan 2 it will cut off my fan 1 I don't really test that they both work manually like you did

Great video very informative and to the point thank you.quick question does the fan clutch also hold the water pump pulley in place ?would I need nut to take the place of the fan clutch?

I did the same to my 03 Silverado, trust me you won't be disappointed. I commented back on one of your old videos and told you that you would love them. I bought the harness for mine though

Good job explaining that I’ve always wondered how are the low speed and high speed works 🤛🏻

awesome video. thank you. did you notice any mpg improvement ?

I love nice cold ac,that V8 screams. Did anyone notice the truck shaking at 37:47 or was it the camera??

I just did this upgrade on my 03 Yukon Denali and I bought a harness new on eBay for 50 bucks plugs in ecm program the ecm with efi live works fantastic

Definitely going to do this on my 02. And just run a inline hose adapter with fan switch until I can afford hptuners

Yea the efan conversion is a good swap but sence I run a compition sound system makes it not a viable option right now but I'm gonna get a larger alt.then I'm gonna do the efans swap thanks again me and my yukon needs this kinda info.

Now i have to do this mod to my 2001. Thanks

You should get an Airaid modular intake tube. It will clean up the front of the engine a lot.

Excellent. Get a tube of automotive electrical silicone grease and put some on each fuse & relay pin when assembling. In fact use it on all the electrical connection points. If the Auto Zone guy looks weird (or tries to sell you tiny light bulb packets of the stuff for way too much money) just find someone who knows what you are asking for. It will prevent corrosion down the road and helps a lot with the cheap Chinese metal used in pins and fuse blades.

I did this recently with my 02, pin 33 was still having issues with my Blue/Red ECU connections, had two ECU’s programmed. Couldn’t get it to work, so I just spliced into pin 42 and solved my issue. But love your clean install.

Thanks for the video. I’m looking to do this upgrade on my 2003 Sierra 1500. I have already picked up a larger radiator and will hopefully get the fan assembly and factory harness in a few weeks. My question is about the computer tuning to tell the fans to turn on. Will this work on my 2003? And if I can’t find a local shop to do it do you know any mechanics I could send the ecm to tune it?

I have an 2003 burb with 5.3 LM7. I’ve been thinking about swapping to oem efan to help mpg and some more hp? 2003-2004 5.3 285hp. 2005-2006 5.3 295hp. Only difference is flex fuel compatibility and switch from mechanical to electric fans. Guessing the fan switch is what netted the +10hp.

Clean job as usual! I’m really curious about any mile per gallon gain from this

You should check your refrigerant level. My trailblazer i run two electric fans from a 2002 camaro. With both fans on with low refrigerant was cold but not super. Then once I was able to determine my shrader was leaking it was cold even with no fans on at all.

Your beard is epic!

Great video !!! Have you noticed any current draw when driving with the new fans ??

Im about to do this mod on my 04 avalanche. I have the fans and harness. Would it be worth buying hp tuners and doing it myself and did hp tuners cost? This is a great video btw. If I was this video before I bought harness I definitely would be wiring up fans they way you did yours.

I did this too just wired them both to a switch I do wanna upgrade the alternator though cause they pull some power

When I did the E fan conversion on my 2002 Tahoe 5.3 I noticed. no difference in horsepower or 0 to 60 times

I found the factory harness on ebay and fans on marketplace finally lol
