Did the conversion as well, my suggestion get a bigger alternator. I didn’t realize the fans at high speed takes a lot of power. Got a 130amp alternator and bigger serpentine belt and it works perfectly!
I was looking at Mechman Alternators on their website, and they sell a 250amp for about 524.00
They have Alternators that's like 370 and 400 and even have an option for a dual amp setup too. But I'm trying to be modest so I'm going for the 250amp option.
How was the new alternator setup?
Lucky enough my Yukon XL Denali is factory equipped with a 130amp alternator
thank you, finally someone said it.. the ugly CONSTANT fan clutch noise AND the slight loss of power.
This video really helped soo much compared to how other videos were trying to explain it😂
Air hammer 🤣 used mine last night perfect for wheel bearing in the north too 👌
Did this mod as a kid with my dad!
Can you please show the whole running process in depth it’s all I need please
Amazing video but is always better to get at least your harness from an used truck 05 forward u can get it on a junk jard u dont have to put those relays on top they hide nice and is all stock works amazing tho
That’s what I did. Got a harness and fan from a tahoe I believe (it was already taken off for me) got a fuse cover off a Denali. All good 👍
Clean install getting mine swapped tomorrow on a 04 Colorado
Did u ever get that Colorado done I have an 08 and want to do it too
Videos Chill af
I was thinking of doing this on 02' Blazer ZR2 4x4 but it's getting 16mpg with the 4.3 & a new Severe Duty Clutch Fan..
It's just hard to keep it cool down here S of Houston. Normally mine runs around 200° on hot days but not it's running 205 to 210° that's with a 195° thermostat.
I would like for it to run cooler when towing a small Utility trailer but she's doing well.
I've never heard my Clutch Fan when it kicks on & off but it moves are fast & quiet.
I slap a wrench on mine & with 1 tap of a hammer, she's loose.
Thanks!
Here is a question didn’t know if this will run off the pcm on a 2005 Chevy. 2500hd 6.0 I don’t think any of them came with electric fans
I did this on my 03 denali, when my ac is on only the passenger fan comes on, and on high, regardless of temp. When ac is OFF, both fans come on low. Regardless of temp! Should the drivers side fan come on while ac is on at any point? Also, should both fans spin at high at any time. Not sure what's going on.
Mechman Alternators if you want to upgrade check them out.
My tuner set it at 205/198 low speed and 212/209 high speed. But I have the stock thermostat though. I think you should so 190/185 low and 205/200 for your truck.
Hey! Will this work on a 2000 5.3?
What AMP rating is your alternator? I have a 2001 Tahoe is the two pin PCM hook up be the same?
The process should be identical for the 02 Suburban correct?
Need the fan part number
What temperatures did you set it at bro?
Doing this conversion on my s10
Can I take the fans and the oem fan harness/ relays from an 05 or 06 truck depending the ecu plug and send my ecu out to be programed for the electric fans?
Do you have to program the ecu where the pins go to activate the gana to turn on and off
Why the colors switch makes no sense I seen so many different say same color then some say switched colors ?
Can you drop a link for the Electric fan I have a 92 Chevy that has a LM7 ls swap and I’m looking into doing a swap like this
Awesome video, i have 2 tahoe's a 2000 and a '04 fixing on installing e fans on both first will be the '04, i have read somewhere else that a higher amp alternator might be needed, currently have the 145 on the 04 and wanted to ask if it is necesary to upgrade the alternator am also looking into adding a secondary battery to avoid it leaving stranded on past occasions, any input would be greatly appreciated.
Mechman Alternators
List of all part numbers?
How much more MPG will you get?
He says this is what type of tape, Audi and Volkswagen use and they were wire harnesses. That’s why all of those cars they have electrical problems.
I live in Kansas and own a '97 silverado 5.7. is there considerations due to temperatures below -20 degrees?
what was the approx cost of this conversion?
Link for the radiator?
Are you still doing a giveaway on the Silverado?
is there any you recommend for a 97 sierra with a 5.7 v8
Love the Vid but a shrouded clutch fan has more flow and cooling capacity than a set of even the best electric ones, just because the mechanical fan blades can have a much more aggressive size and pitch since they're attached to a 300hp V8. Now, the downside is it takes much more HP away from the rest of the system to drive the mechanical fan so going electric will make it feel a little more peppy, and you wont have that annoying whoosh during slow acceleration. But for this application, the electric fans are still more than enough to keep that LS more than cool
These trucks suffer the most when sitting still at idle. They don't usually overheat, but the AC will get warm at the very least. There just isn't enough airflow without some engine speed. The "GT Series" fans & 34" radiator should be more than enough for most use cases, and were what the OEM used on later models (some trucks, Escalades, Yukon Denalis, etc...) I would recommend that 2500/3500 trucks primarily used to tow heavy loads stick with the clutch fan.
Exactly ^
At road speed (even 45mph) the clutch fans do fine but at idle (drive-thru, stoplight, etc) they suffer big time. Especially when it's 100+ ambient temps. Thays where electric fans outshine being able to hold full speed at idle.
I have disagree. Every clutch fan vehicle I’ve owned, the clutch itself was worn not letting it spin at the proper rpm when at idle. Replace that, and I’ve never had a truck that wouldn’t drop temp at idle in 100+ ambient. When working properly it damn near sounds like a jet engine. Blows the dust away in front of the truck
@@pcmofncorders2270 I have 2 2500 Suburban's and haul a 6k trailer daily... Stop and go driving, highway, you name it... the clutch fan struggles, the temps get hot and the AC gets warm... where the Efans keeps on top of the temps... and the AC is always cold. Never had an issue with the Efans... but the clutch fans, Junk. This comes from many years working my suburban's with or without the trailer, cooling at Idle using AC with the stock fan is no good regardless if its a 1500 or a 2500.
The factory harness is cheaper and so much cleaner I really don’t know why people go with these kind of options.
What’s the tune on it..the video just showed the 2 fans. But do the temperatures and the Ons and Offs stay the same?
Did you get it working already? 18:40, pause video and copy what you see on vid to your file. But you can have speeds turn on to your liking.
FYI the towing models come with the bigger radiator from the factory. They also have heavier suspension and such. I prefer that model since I tow and like heavier duty at the cost of some speed. Most guys are going with the 1500 light duty builds for weight, but then have to swap up to the radiator that comes in the heavy half and 3/4 tons.
Fuck yea my dude!!!
How much would I shop charge for ecu to turn on efans?
To be honest, where I live in Nebraska, most shops won't do it unless if it's a custom shop that will also do automotive mechanic stuff. If you're mechanically inclined and can do most the stuff yourself, a shops should just charge you for tuning only and in Nebraska the only shop that does/charge for tuning is a out 250 an hour the last time I checked.
When's the Audi video dropping?
Where was the new radiator purchased?
Autozone
Do you know what cfm those fans pull?
They're stock pontiac GT fans which model I'm not sure
do i need have credit on hp tuner to do this?
Yes you have to be one or two credits I can’t remember how much the GM one is for this truck
@@CameronAlford can this be done with other brand tuners?not hp
@CameronAlford what do you mean by credit?
@@Forgivefull HP Tuners uses a credit-based licensing system. Credits are used as currency to purchase licenses for the different modules in a vehicle. Licensing a module gives you the ability to tune it. The number of credits necessary to purchase a license varies depending on the vehicle.
Many vehicles are (2) credits for licensing the ECM/PCM, and may have additional options such as a TCM, FICM, or CCM.
You can find a complete list of supported vehicles and credit cost on our supported vehicle page here.
@Metal.master110 so if I'm reading this right, do I have to buy these credits?
Which fan did you guys use ? One off a 06/07?
Did you find out?
I have this kit it uses Dorman 620-654 fans (06 fans)
Part number on the Dorman electric fans? Already have a 34” radiator, and work in an auto shop so I have access to parts. Only this I couldn’t find in this video was the Dorman fan part number 🙁
Find it yet?
620-654
I don't trust doorman simply because every product I bout from them went bad, I mean if you're on a budget then I get it, but if you're trying to keep it for a while and don't want to cheap out then I would go for Perma-Cool Electric Fans.
I have Perma-Cool for my 04 suburban and I can just feel the quality when I drive.
Since when does a Chevy overheat?
When your stock radiator cracks or when your waterpump goes bad from your clutch fan
This is not true you don't need a computer problem to run efans. I did this conversion on my 2004 suburban. It runs straight to the battery and alternator. On the downside if you put the key to on position some fans always run
Its always on because it needs a switch from the computer to cut it off which the computer does
