ATTN LS SWAP FANS! - Adding OEM COOLING FANS To Any LS Swap - UTX 

👋👋 Hey guys, Emily here again. This video has some weird glitches towards the end again... Just wanted to acknowledge it and let you know I'm doing my best to figure it out! We appreciate you guys watching!

Wow those fans are big. That's great

I can’t tell you how much I just learned about wiring up the fans on an LS based swap. Very educational and made things so much clearer. When you out the numbers on the relays it a made sense. Oh and I love the banter between y’all. So funny.

The cleanest work on this platform.

Good choice on the ratcheting crimpers. They work GREAT. Been using them for almost 30 years. Will never use anything else.

Love the intros. Great content as always.

I just finished putting an lq4 in a 87 Land Cruiser and this video was super helpful, great diagram and walkthrough, thank you

very nice. i did the fan install in my 99 suburban. I gotta admit with the hot days lately over here it has been worth it. i never need to use high mode. keep me cool with the ac going cold. Keep up the good work

Love the simplicity!

Awesome video!!

I was considering putting electric fans in my 2005 2500hd, so it sounds like I might have the wires in the harness already. If not, I now know how to put them in there. Thank you, Jerry and Emily, for a valuable video and for sharing your knowledge. Awesome, and juice is cute, too.

Great video guys , thanks so much

Thank you so much my fans are working perfectly

Awesome. I've got the LS swap thing pretty much down, done 10 of them with my last '68 C10 but the wiring always holds me up. I don't mind doing it but even simple things like the fans can be a chore and take an inordinate amount of time when done right and I'm talking stand alone not harness work. It's my Achilles heel. You all are the harness kings, I'm learning so much just watching. I was going to use a stock harness on the C10 but I just have to get it running so not this time but I do have a 4.8 with a T5 sitting in the back of my garage looking for a S10. Strictly low buck I'm going to take my time with that one and use a cut down stock harness and using a stock fan is a lot cheaper than picking something aftermarket. I always like developing new skills even at my advanced age, just built my own stainless steel exhaust and my MIG welds didn't come out all that bad with flux core and tri-mix but now it's on to the harness work. I have a half dozen of them, all but one DBC and it's time to get on the horse and work it out. Thanks so much for your video's, I have them archived and will be using them going forward, a lot.

Yet another very good video. I’m working on another ‘97 Subaru EJ25 into a ‘73 Beetle. The fan relay wiring is so crucial in any vehicle. Running the 3 relay setup in parallel/series this way is rad. Going to give it a try in this project. I know this is LS/OBS swap videos, but the wiring is kind of universal in its application. I’ll eventually find the right truck to do my LS swap…

I needed this really bad 😂

Great video

You guys have one of the best intros

This is going to be a good one done hit the like button cuz you know it's going to be good ready to do a little learning

Great video. What are the reasons you don't like the solder connectors on large wires? I got some after watching your video and I like them.

hey there thanks for another amazing and educational video, what brand of crimper and pole dancers is that i tried to pause and read but could not confirm. I love the corn in the beginning

good afternoon 😊

YOU GUYS ARE SO FUNNY!!!!!!

I'd like to see you guys do a 88-98 obs. They are a super popular swap and lots of questions on the net. Preferably a 89 since that's what I'm going to be doing😊

Yea i like how the pigtail wires are always the same color. NOT!!. That makes it way harder lol.

Go Hoggs🎉

Is there a way you can tell what ECU you have by year? You mentioned that the 05 ECU had the ability to regulate the fans but previous years didn’t. Can I guy just look at the part number of an ECU and tell it’s a 20XX model and it’s good to use. I only ask because I ordered my unit online and a year never came up. They did however tell me in messages they turned on fans during programming so I’m assuming they used like an HP tuners program to flash and update accordingly.

It's so hard to find good help 😂.

Have u had any trouble with the pigtails recently had some other one burn on me i believe 16-18 gauge & these look thicker gauge like 10-12 on wire ?

I think you mentioned you bought the fans brand new. Do you remember where you bought them from? Thanks!

Can you give me the part number for those fan pigtails? Thanks

I did the same wiring went over it over and over to make sure I wired in the wires the same way but mines don’t come on. My question is if I run aftermarket universal fans will it still work or does the factory fans something in them that allows them to run at a low speed and a high speed that universal fans don’t have? I’m pretty new to wiring in fans and I’m just trying to finish up a truck build that was abandon it runs and drives just no fans

This is more of a question than a comment. Followed the process to the T. Why is my 10 amp wire turns on fan when the ingition switch is off, But cuts off when turning on ignition?

Gus here wondering if you got my email about were to send the AC bracket to?

I love you guys. I always wait for new videos. Pull up my name and there is a short that may help you out. I found a way to strip a harness pretty fast.

Hey Guys, Thank you for all the videos. I have used so many to do my swap on a 82 c-10. Quick question my fans are not coming on engine is off a 2006 Tahoe with electric cooling fans. I used the original fusebox/harness which came with the fan relays already wired in. They should come on without needing any wire modification? or is there still wiring that I'm missing? Thank you Vence

I didn’t know Emily had only fans ? 👀😀

I hate when they make the pigtails the same color wires. I understand that different colors were used on different years. They should just use red and black when they make them.

That's so corny 🌽 lol

His comment simple No it ain't simple maybe for him cause he is a electrical goo ru engineer type and thinks like a college professor

Who sells zip ties??🙃 Do your engines run hotter with electric fans than with a mechanical fan??

To many Oks
