How to Install Electric Fans on your GMT400

[@bluzeblast]

I'm sure your son loved working with you on this project. It's great he loves to run and play like a kid should. I miss the times my Son and I had to do projects around the house. That's okay. I have grandkids now, so its all good...Ive been wanting to do this to my ol' 96 chevy k1500. Just havent gotten up the nerve yet.

[@WorkingwithBobby]

@bluzeblast yeah man, every now and then he will help me out. I enjoy spending time with him. I hope the video helped you to pull the trigger on the right electric fan set up for your truck.✊🏾✊🏾

[@OpenBarGarage]

Awesome video. I can't wait to listen to my exhaust instead of my fan constantly running uselessly.

[@WorkingwithBobby]

😆😆 I understand how you feel dude! I'm so glad I did this and glad the video blessed you.✊🏾✊🏾

[@robertclarkguitar]

Thats cool man!!!! Main reason is cooler engine and a slight bump in performance along with easier to get to waterpump and all in future repairs. Wow!!!!

[@WorkingwithBobby]

Thanks dude! I believe if I had a better fan setup or maybe a dual fan system, it would have been even more efficient. I ended up putting the OEM fan and shrouds back on because once I added a new condenser and external Trans fluid cooler, I was haven't overheating issues. I uploaded a video about the change. The overall concept is the same though. Thanks for watching!✊🏾✊🏾

My guy thank you so much for making this video I've been thinking about doing this with my 96 cheyenne

[@hectorhernandez7648]

Hey man awesome video very helpful, just one question. Where can I get that adapter you have for the temp sensor?? Thanks

[@WorkingwithBobby]

Thanks man! They have those brass adapters at the parts store normally on the help isle. You can also get them from Amazon if you know your NPT thread size. Hope this helps!✊🏾✊🏾

[@DUKE-bc4ig]

Good job.. one question i wanna know.. if you turn off your truck when the temperature is still high, does the fan stay on until it cools down??

[@WorkingwithBobby]

Thanks man! I have since removed this fan and installed the factory mechanical clutch fan but, to answer your question, it did not. I had the signal wire from the relay tied into key-on voltage. That means the really will not energize unless the key is on.

[@DUKE-bc4ig]

Okay, but what made you go back to the factory setup?? I thought electric fans were better than the clutch

[@WorkingwithBobby]

@DUKE-bc4ig I needed dual fans and the correct sized fan shroud. I was running warmer than I was comfortable with after I fixed my AC. I believe going electric fans is always beneficial when you do it right. I'm gonna install a bigger radiator and a dual fan setup with needed amount of cfm for proper cooling.

[@DUKE-bc4ig]

Okay, I just saw your order video about you talking about it.. thanks because that's information I definitely can use going forward..

[@WorkingwithBobby]

@DUKE-bc4ig yes sir! That's why I put it out there. If you do go electric fans, make sure you get the right fans for your application. When I can afford it, I'm going back to electric fan and I'll do a video on the install.

What size fitting did you use for the thermostat?

[@WorkingwithBobby]

@@melapela5 I used what came in the kit. I'm not sure what size it was.

[@brianfox7775]

Great video . Has it worked well since? Any battery drain while running the a.c.?

[@WorkingwithBobby]

Thanks Brian! I haven't had any issues whatsoever out of this fan kit. So far, not so much as a fuse has even blown. I need to upgrade the radiator on my truck and I also made a bone head move of reusing head bolts when I installed the vortec heads years ago which cause seeping here and there. Otherwise, the fan kit itself is flawless!

[@brianfox7775]

@@WorkingwithBobby great news . I will order one today. 👍👍

[@bigjune4588]

Niceeeee and clean hell yeah 💯💯💯

[@WorkingwithBobby]

@bigjune4588 thanks dude! I kinda wish I still had electric fans.

[@bigjune4588]

So you switched back to clutch fans?

[@WorkingwithBobby]

@bigjune4588 yes sir. I didn't want to but, had no choice. This particular set up is nice but, I did not have enough cfm flowing through the radiator and condenser with this one fan. I will do a dual fan set up in the future when I convert it again Lord willing.

[@jesuschristgarage7064]

How has it held up? Is it worth it I’m currently rebuilding my c1500 and this is on my list , I’m thinking on buy the dual electric fans from a 2005 Silverado

[@WorkingwithBobby]

It's holding up really good. I haven't had to do anything to it since I installed the kit. I kind of would like to upgrade to a fan system that fits the size radiator that I have though. The 2005 Silverado dual fans fit the obs truck radiator?

[@jesuschristgarage7064]

@@WorkingwithBobby that I’m not sure but I happen to have both trucks so ima be measuring

[@WorkingwithBobby]

@@jesuschristgarage7064 if it works, let me know. I would rather have a radiator fan setup that looks "factory" instead of that shiny aluminum look.

[@malcolmeatman-goode8201]

Great job my brotha. How’s the AC blowing?

[@WorkingwithBobby]

Thanks. It's not blowing at all now. I did not have enough fan cfm for radiator AND condenser so, too much pressure built up on the high side and blew out the seal let all the refrigerant out. I need to upgrade my cooling system before I can have AC again.

[@malcolmeatman-goode8201]

@@WorkingwithBobby so this fan set up isn’t cooling the condenser efficiently? I’m just wondering cause I’m switching to electric fans because of my AC not cooling well here in Texas. I have brand new compressor, confessor, accumulator, evaporator, hoses, etc but it can’t keep up with the heat.

[@WorkingwithBobby]

@malcolmeatman-goode8201 it does not. I had no issue with cooling until I added the condenser and tried to put AC back on. That's why I feel I need to upgrade. I'm currently looking into some options and found a company called alloyworks who makes a radiator and fan kit that I might order when I get the money. For right now, Belle is down.🥺🥺

Can you keep your original temp gage does it work as normal

[@WorkingwithBobby]

Yes, I still use that for my gauge in the truck. The new sending unit is for the fan control.

[@mrworldwide6770]

I think I have to install my switch on the side because mine has a 2 connector at the top on the intake but a single wire on the one of the side by 1 and 3 spark plugs

[@WorkingwithBobby]

It's ok if you do. There's a plug you can remove from the cylinder head near the exhaust manifold to install the switch.

@@WorkingwithBobby awesome thank you for getting back to me I live in Cali and finding parts like these is hard but I manage for find everything I also got a cold air intake that goes into the side fender for like 90 bucks and the jba headers for 167 and they bolt right up the stock pipe

[@luismedia8823]

Hey man, do you have the links for everything you bought?

[@WorkingwithBobby]

Whats happening? I'm sorry man, I don't. I ordered the fan kit and shroud from Amazon. The fan kit came with the harness, sending unit and fan itself and the shroud was a separate order also from Amazon. I only remember that the fan shroud came from a online store called assault racing. If I look back into my history and find the order itself, I can share the link in this video description.

[@drummaboiferguson2144]

What size radiator n fan shroud

[@WorkingwithBobby]

It's an OEM replacement radiator and I have links to the shroud and fan kit in the description of this video. ✊🏾✊🏾

[@mrworldwide6770]

28 or 34 core

[@moycorral7870]

You think one fan is enough?

[@WorkingwithBobby]

Good question and to answer your question, no, it was not enough. My truck ran 10-15 degrees warmer with this setup. I needed dual fans. I have since put the mechanical fan back on. I will go aluminum radiator and dual fan setup soon....

[@moycorral7870]

@@WorkingwithBobby you think getting two of these would be fine?

One last thing how exactly do you get this clutch fan off

[@WorkingwithBobby]

Good question. It was easier for me to remove the drive belt after removing the top half of the radiator shroud. The you can turn the water pump pulley by hand to access all the fasteners. I took a pair of channel lock pliers and used them to hold the pulleyvwhile removing the fasteners with a gear wrench. I hope this helps.✊🏾✊🏾

@@WorkingwithBobby update so I found out I just have a bolt on style for the 95 model my last question is do I have to run a different thermostat if my kit comes on at 180 and turns off at 165

[@WorkingwithBobby]

@mrworldwide6770 ok, that's fine. You don't have to change the thermostat unless you want to run one that matches the parameters of the cooling fan kit. Other than that, the temperature switch that came with the kit will control the fan according to coolant temperature as it should.
