Cooling fan assembly P/N's?

I'm doing an lt1 swap on a 89 GMC Sierra c1500. I need to switch to electric fans. The Sierra radiator is the same height and thickness as the b-body radiator. I'd like to use the b-body fans. I have the mounts figured out but because my car had the v08 package I only have one fan. I'd like to buy one new but can't seem to find one. Everywhere I look the fans that are listed for b/d body's aren't even remotely similar. The only fans I can find that look like they can work are listed for lumina and such but a lumina radiator is only ~14" tall and a b-body radiator is ~17" tall. Because the fan mounts to the top and bottom of the core they theoretically shouldn't work. Does anybody know part numbers for the entire fan assembly on these cars? The fan wattage or left or right doesn't really matter for me as long as it was for these cars. If I have a choice I'd prefer the 240 watt fan though.

I attached a couple photos. The fan with part number 12003 is what is listed for a b-body on rock auto. The fan with part number 12071 is listed for a lumina and looks similar but theoretically won't work.

You should be able to find the fans at the local PNP junk yard. The only car that came with the 240w fan was one of the Fleetwoods, and I believe it was the driver's side fan. The fans are not to difficult to find. The pictures may be generic pictures as well, and you should get a compatible fan from Rock Auto. If not, return it.

Yes and NO. As Fred said a JY should yield a correct fan assembly. The V08 option the OP mentioned contains the 240W fan (secondary) and the mechanical fan. All 94-96 B body with the HD cooling, tow package, etc. had that fan - not just Fleetwoods - where did that come from? But you can only install one 240W fan per car, not 2. The RA pic of the left fan looks correct, comes as 3 GM parts - fan blade, motor, and frame, but pricey as shown so try ebay or JY as that is the primary fan on every 94-96 B body. Lots out there.

A 94-94 FSM will provide a wealth of info.

I assume, you will use the Innovative wiring conversion kit?

You need a radiator with the side mounting tabs installed, not just top and bottom brackets.

You already have the 240W fan, right?

The V08 cooling option that came with the V92 tow pack upgraded the primary fan from a 150W elec fan to a 7,457W mechanical fan, and kept the 240W 2ndary.There are two optional cooling system upgrades for LT1 B/D-cars, called V03 (Extra Capacity Cooling), and V08 (Heavy Duty Cooling). Performance models such as the WX3 (Impala SS) and 9C1 (Police) cars automatically get the upgraded V03 (Extra Capacity Cooling) system. V03 includes a larger radiator, an increased capacity A/C condenser, and an upgraded secondary electric fan. V03 is also optional on most B/D-car models.
Note that the '94 V03 (Extra Capacity Cooling) option uses a 150-watt primary (RH) fan, and an upgraded 240-watt secondary (LH) fan. In '95-'96 the V03 package was revised and no longer included an upgraded 240-watt secondary fan. Instead the standard 100-watt secondary fan was used, which is the same as the base cooling system.

This seems to be correct as in my part of the world I have only seen the 240W fan on my B4U and it is a 94. Some of the RCMP 9C1 were ordered with the L99 and got a standard fan instead of the 240W so I expect the V03 150/240W package and V08 mechanical/240W is very rare.

You'd be right about the junk yard if I lived someplace else. Here there's about 8 b-bodys in town. 2 of which are in my local yard. They've been picked clean. The next nearest yard is about a 200 mile round trip to a pull-a-part. By the time I spend cash on fuel and the part I could have bought a new one. New is my prefered method anyways but I may have to go with used.

The picures don't look to be generic. I've searched the numbers and numbers for other manufactures and they all look to be of that style.

Skip white fans are ridiculously cheap. Any body have experience with their fans. I don't like the idea of universal fans for some reason. I'd rather use some oe fan. If the b-body fan doesn't work out I'm going to go with 05'> silverado fans.

Yes the 240w fan was used on the V08 packaged cars. I had one and the fan is a 240w. The method I'm using to mount them will make the fan interchangeable from left to right so 2 of them are able to be installed. Being on a truck used as a work horse and will see some mountain towing, the bigger the better. I won't be using Garys harness. I'm building my own engine harness and reworking the engine compartment harness in the truck. I'll just integrate new beefy fan wiring when I do that.

you could just make simple flat stock metal extensions for the Lumina fans to mount on the taller (17") radiator. Basically a small piece the size you need with a hole at each end. One attaches to radiator the other to fan

So you want another 240W fan assembly? I have one, not sure I want to sell, they are easy to find, check ebay. Fan brackets are unique to 240W and other ones, will not interchange, cannot put 240 fan on 100 or 150W bracket. 240W fan is fat and flatter, other is smaller. Still not quite clear on all you need. (2) 240W is overkill. My fans never run with AC off and lowered turn on temps. A bigger, better radiator would do more good. A good OEM GM fan is probably better than anything else. You get what you pay for.

Rethink Innovative harness, you have to mate into PCM and fuse box, he has done all the engineering and build quality is superb.

That Quote is contained in the link below:


LT1 cooling info | Grumpys Performance Garage

You have to scroll down about half way in the pdf under B body cooling. Lots of info but much is F body, etc.
It it was written By Scott Mueller years ago along with much other valuable LT1 info. That and the Qalo Handbook which is now buried in the stickys seems to be very hard to find. This all quite depressing as we are losing our library of knowledge.

That quote came from this forum. It is quite possible it is Scott's. I use to get a lot of information from Scott's posts. The google custom search finds less and less good information and more "popular" answers.

Thanks for the Grump's site post. It looks like a lot of good info.

Custom wire harnesses can be made with good hand tools and will work as well as machine made crimps. Cheap crimp tools make bad crimps.
