Shroud is 609 mm wide x 585 mm tall ( 24x23 inches)

Fan itself is not much smaller.....

So i gave these instructions to a friend to wire up the Vette PWM module. I told him to use pin J3-64 as the signal wire. He says it doesnt work and used J3-49 instead & it worked. What's up? Which pin have you guys used?

J3-49 is correct for E67 PWM fan output control. (assuming you have also changed calibrations for PWM fan control)

Thanks Dave.

Plugged it all in tonight to test, and after a few small bugs, it works! Its cool. No spike in amp draw, fan starts up slow, runs at a lower speed until you t gets hotter then runs faster. Cool.

I'm still looking for the real Bette connector and f anyone finds a source. I just used individual spade connectors.

andrewb70 12-26-2014 08:46 PM

Scot,

What fans are you using?

Also, does anyone have the dimensions of the C6 fan pn 15819952 ?

Andrew

samckitt 12-27-2014 06:22 AM

Before I started the LS swap I had an LT1 in the car and was using mid 90s impala SS fans. Still using them. I'm using one corvette module to power both fans.

andrewb70 12-27-2014 11:31 AM

Thank you everyone for posting the relevant information. Looks like I can use a C6 Corvette fan (it already comes with the controller plug), in my Cougar build. The plan is to use the Corvette controller module with the Holley Dominator ECU.

Anyone see any reason why this wouldn't work?

Andrew

Anyone know if the PWM output #1 (pin A19) on the XFI 2.0 can be used for fan PWM controller input?

samckitt 12-29-2014 08:59 AM

I want to add a Maxi fuse to the existing GMPP fuse box for the fans. I need this terminal for 10 or 12 gauge wire:

I was at the junk yard today looking for some other stuff & came across a Cadillac that had a fuse box for the Max fuses only. I removed a couple terminals out of it & used that to add another circuit to my GMPP controller harness fuse box. I also discovered that the GMPP harness fusebox was used on full size GM trucks, Suburbans, & Tahoes in the mid 90's.

Here is pic of one I found in a Suburban:
http://i242.photobucket.com/albums/f...230_102157.jpg

http://i242.photobucket.com/albums/f...230_102217.jpg


On my fuse box I cut the bus bar that feeds power to the Max fuses so I could pass the wires through the bottom of the box instead of routing it outside like it came from the factory. I moved those fuses up 2 spots & added the one for the fans. I found a Max breaker at the junk yard. I wrapped the wires with a zip tie to keep them from rubbing the buss bar where I cut it.

Most of that catalog comes from this http://www.google.com/url?sa=t&rct=j...82001339,d.cGU

There's a boatload of other Delphi info available. Just search for Delphi Global Connection Systems Catalog, grab a barrel of popcorn, and settle in for a spell.

Carl,

Thanks for the link. What an amazing array of products!

Has anyone used a C6 radiator fan on their project? The reason that I ask is that I plan to use one on my Cougar, but I want to know how accurate the pictures are.

The AC Delco looks like this:

http://www.rockauto.com/catalog/more...566&cc=1442776

Some of the other off brands look like this:

http://www.rockauto.com/catalog/more...346&cc=1442776

I want one that looks like the AC Delco, but I read a review on Amazon that has me questioning the appearance. The review said that it didn't look as advertised, which has me scared to order it. The listing on Amazon has the following (scary note):

"Note: ACDelco partners with other manufacturers to supply the parts your car was originally built with. This product is in a ACDelco package, however the part may have been manufactured by an independent ACDelco supplier and could have a different color or shape than the product image above."

Anyone use the AC Delco one? Did it look like the one in the picture with the full shroud?

Andrew

Syclone892 01-04-2015 08:19 AM

Hi Andrewb70, the vette controller will work with the holley dominator as I am doing the same thing :-)
I haven't finished putting it all together but I did test it before going through all the work and it worked great! Just remember to turn the ignition off and resync it after changes otherwise it didn't accept.

I did find that the c5 vette controller terminals are the same size as maxi fuse terminals so that's what I used and just put hest shrink on the ends.
Thanks for the help here guys I really like this setup :D

Thanks for the info. I ordered a Dorman C6 fan through Amazon. It was $80 shipped and it already comes with the proper plug for the fan controller. Now I see that same fan for $121...Looks like I got a pretty good deal. I will post pictures once I get it.

That's about an 18" blade then?

Andrew, when you get the assembly can you get some measurements for me? Blade diameter and depth of the motor/blade please. Thanks!!

Donny,

I sure hope it isn't an 18" blade! The C6 radiator core is only a hair than 17" tall, so I suspect this fan has a 16" blade (hopefully!).

http://www.rockauto.com/catalog/more...645&cc=1442776

I will definitely post pictures and dimensions when I get it. Should have it tomorrow.

It was a total fluke. I've been researching these parts on various websites and I had seen that fan on Amazon for the $120 price. Then I checked it again a few days later and it was $80. I couldn't pass it up. Surely it can't be that bad, plus it comes with the proper connector for the C6 fan controller.

Andrew

dontlifttoshift 01-05-2015 10:07 AM

The dimensions on that radiator are a lot smaller than the dimensions shown on the fan......that's why I guessed about 18"

I am hoping it is a 16" blade. If you look at the fan picture, the shroud extends past the blade, and the shroud has to fit on the 17" core.

Andrew

andrewb70 01-06-2015 01:50 PM

So I got the C6 fan today. Not surprising, made in Taiwan, but who cares, iPhones are made in Taiwan too...

The fan assembly doesn't match the picture that is posted on Amazon. I don't know if there was a design change on these at some point, but here is what I got:

http://www.pro-touring.com/~andrewb/cougar/177.jpg

http://www.pro-touring.com/~andrewb/cougar/178.jpg

The fan blade is 16.5" and it comes with the right connector to plug it into the C6 fan controller. There is even a little molded cradle for it. Imagine that.

http://www.pro-touring.com/~andrewb/cougar/179.jpg

Just let me know if anyone wants any other measurements.

Andrew

dontlifttoshift 01-06-2015 02:18 PM

Thanks! I think I will replace the LS1 F body fans I have with that. I kind of like the half shroud, half open design, better than the full shroud.

Donny,

I don't hate the open design. Once a car is moving you want as much air as possible to just flow through. I wish the C6 radiator didn't have that funky angles upper hose. I would just use it in the Cougar and this fan mounts right to the radiator itself.

Anyone have any creative ideas how to mount this thing?

I don't recall, do you already have your radiator? If not, can you have the mounts built in place on the end canisters just like the picture?

What is this picture of the fan mounted from? Any close shots of the mount points?

samckitt 01-07-2015 12:33 PM

I went to the junk yard yesterday & found a couple modules with connectors on fans that were busted. One of the connector bodies has a little damage to it, but still seals out the weather.

Who wants one?

I'm new to this forum, but I've been working on a couple pro-touring type Camaros for about 6 years. I'm on Pro-touring.com, but I haven't been active on this site, just lurking. I really appreciate the effort that went into this thread. This is an elegant implementation of a PWM controller for the cooling fans. I've ordered all the necessary items and will have mine hooked up soon too. Thanks for all the info.

I'm wondering if we could extend this solution to get rid of the binary switch in a Vintage Air system and let the ECM control the Sandeen compressor too. As I understand it, the function of the binary switch is to protect the compressor. That is, if the AC pressure is too high, the binary switch interrupts electric power from being delivered to the compressor clutch. Likewise, the binary switch will also turn off electric power to the AC clutch if AC pressure is too low. It seems logical that GM would implement a similar safety feature in their cars. And, since the AC pressure sensor is coupled to the ECM, it would seem likely that this binary type safety feature would be implemented in the ECM. Thus, I'd expect that there's a software routine in the ECM that uses high or low AC pressure to turn off the AC compressor clutch, and we might be able to modify this routine to use pressures that correspond to the Sandeen compressor instead of a production compressor. Moreover, I'd heard that GM's ECMs turn off the AC clutch if WOT or high RPMs is detected. The same routine may handle these functions too. These would be features I'd like to have implemented in my cars too.
I'm not highly experienced with ECMs and their software or with AC systems. I'm just trying to think about this logically. So, feel free to tell me I'm all wet, and/or point me to some materials that would help move this matter forward.

You are correct in that GM ECM's do control AC compressor - however - GM ECM's receive AC compressor request signal over LAN from BCM (no discrete AC compressor request input directly to ECM).

So best solution I've come up with is AC pressure sensor into ECM to control fan output based on AC pressure - then use Vintage Air trinary switch to control compressor.

At least this way you can control fan output from coolant temp, oil temp, trans temp, intake air temp and AC pressure.

Dave

Terrydmorgan 01-11-2015 01:45 PM

Dave,
Thanks for the reply. I see, so if the ECM never receives an AC compressor request, then I assume the output signal from the ECM remains high all the time (i.e., the output is never pulled low by a real AC compressor request from the BCM)? Is there a way to permanently tie the AC compressor input request to simulate a constant request for AC from the BCM?
Terry

Can you tell us more about this supplier?

samckitt 01-16-2015 05:57 AM

I can't give out all secretes yet. But they supply them to the car manufactures. I bought 5 of them. Don't need all of them, so i will have some extras for sale.

Connector parts showed up the other day, the wire seals will show up tomorrow.

Power terminals:

http://i242.photobucket.com/albums/f...122_144656.jpg
http://i242.photobucket.com/albums/f...123_093818.jpg

I have 5 complete sets. When the seals get here I will also have ECM terminals. If you have the GMPP controller kit & want to add the Maxi fuse/breaker in the fuse box to power the fan, I can get the terminal for that fusebox as well.

I spent a ton of time trying to find this connector. If you have searched it you know they aren't available from GM.

When the seals get here I will have everything needed (except the wire) to add this fan module. $50 shipped to anywhere in the US.
