Electrical Fan Install

I need help, I received my LT1 E. Fans yesterday and need help on how to mount them to the radiator. It also didn't come with any connectors to control the fans and I need help on where to get them. :confused:

Oh, and they are a bit dirty would it be okay to wash them.

I looked on FSC.com for some help, but couldn't find any. A lot of people said that the fans from the LT1s and LS1s didn't cool very well as apposed to the stock fan, I don't see how considering they were cooling a bigger engine in a more confined space. Oh well

Please help want to get them installed this weekend if possible.

Thanks,
R.

I wash my engine bay all the time, spray em down and get'em clean, i don't think you'll hurt anything.

Those fans cool very good, i can run the shit out of my truck at the track, just keep hot lapping it, and the temp will never get over 180deg. it can also idle forever and never gets hot, i really like the ls1/lt1 fans.

will your stock shroud fit over the lt1 fans shroud, my setup is completely different than yours, maybe cut the stock shroud and lay it ontop of the lt1 fans, i know some guys just find a good place to but small screws or bolts and just screw them into wherever there's metal, like the radiator support.

kevin mounted his, maybe he'll chime in and let you know how he did it,

don't you know you can't find any technical answers over at that other forum, lol, jk


good luck,

allen

I know, HaHa, J/K.
I hope someone can provide some good pics for reference too.

I don't know about your fan. My 99 don't not have the rad. that Flexilite say it should have. I had to buy another. You can buy a controller for them I would think at a local parts house. My fan is mounted with push thought tie straps on the top and has brackets on the bottom. I can get pictures of it tonight if you want.

Your more than welcome to swing by and check mine out. I mounted mine to the rad. using those ties that are used for a tranny cooler. Thats not the best way to do it but very easy. I'll end up making some brackets for it. I had to ditch the shroud altogother but it cleans up the bay very nicely.

What time are you available, I may swing by this weekend or next week. I don't start work until the 22nd, and I want to get them installed before then.

Thanks,
R.

Sent ya a pm.

I haven't finished them yet but my fans fit just inside my stock fan shroud. I'm going to cut the stocker down and then mount the new fans to it with screws. Then it will bolt to the truck just like it did before.

I used a piece of Aluminum angle to make top and bottom brackets. A better way to mount them is to get a universal fan mounting kit (hayden I think make thems). I was thinking of making a bracket that would mount where the stock fan shroud mounts, but still haven't come up with a lower mount.

i'd be interested in seeing some pics. i think i saw a write up over in the FSC tech forums, but it may not be for LT1/LS1 fans. i think i may try some tie straps that come in the universal fan kits out there.

lets see some :pics:

I will see if I can get some :pics: of the install.

So i guess your finished?

I have had my LT1 fans in for over a year. Let me tell you, they cool plenty well. I use to pull my 29' 6200# travel trailer with my truck to San Antonio, New Braunsfel, Austin etc... and NEVER had a cooling problem. Even with a 4.8!!!!

I do not reccomend using the "pull through" ties. They are the reason I have a 6.0 (34" core) radiator in my truck now. One of them rubbed one of the tubes to the breaking point. I had it repaired and remounted the fans with "L" brackets and it busted again in the same spot (due to bad repair). So I got it repaired again and stored it and went with the 6.0. All the pulling was done before the 34" radiator though. As for the plugs, I just used standard female (to male) terminal connectors and wrapped them in electrical tape and have not had a problem yet.

Washing...NO PROBLEM my engine bay looks showroom new.

Well, not done yet? How long did it take to install and wire, not sure if I can do it today or not. And what tool did you use to get the stock fan off.

I wasn't wanting to go the tie route either. I saw some pics from LS1tech.com where the guy used L brackets that mounted in the stock fan shroud holes and attached to the top of the e fans. How does this sound? Thanks for the info, got any pircs of your setup, they would be great for a reference.

thanks,
R.

got that off FSC a while back :thumb:

:thumb: Thanks, that should help a lot.

OK, I pretty much got the fans installed today, going back tomorrow so my friend can tidy up the wiring. I bought a wiring kit from O'riley's, I is a thermo relay that somehow pokes through the radiator for temp (I guess), and connects to ignition and A/C relay. One question though, is the fans supposed to push the air away from the engine or pull the air into the engine bay. It seems to be cooling pretty well though still under 210, about a half notch lower than before.

Oh, and the fans seems to be on constantly right now is that normal.

Your truck temp gauge may not be as accurate as you would like.

the fans should be pulling the air thru the radiator not pushing the air thru, so it's blowing the air on the engine also.

depending on what stat you got and what the rating the temp probe is set at, your fans should be off when you start the truck in the morning, and may come on during stop and go traffic. if they are on all the time, check your wire that turns the relay on, + or neg, depending how you activate it.

Ok, direction is easy enough. When we installed the fans the engine was cold, and they didn't come on unless the A/C was on. So, the fans should stay on once the engine is warmed up right. I think we set it to come on at 180

ya, that sounds good, i don't need mine when i get on the highway, yours may turn off too, sounds like they're working just fine.


cool,
