    • 87 silverado
This fit and worked perfectly. It would be a lot better if it included a simple wiring diagram but a google search did their job for them. I also purchased separately different coolant temp fan switches to keep the engine running at my preferred temp.

    • Cool product
I use this radiator double fans on an LS swap 5.3 on 1986 C10. And on my OBS 1989 C1500 with L83 gen 5 5.3 Lt swap. On the 1989 you have to modify the radiator support to make this work well but it will work!!!!!!!

    • It's ok I guess
It's a well built radiator, BUT it is shorter than the factory in my 86 k10. Got creative and fixed that problem. Then came the wiring, it was wayyy to short so be prepared to buy extra wire and conduit, and zero wiring diagram. Finally after installation I tested it, the fans came on and never shut off, the thermostat was running it around 140 degrees and fans still wide open, the fans would stay off until it got up to initial temp if you left it parked overnight. Definitely going to get a better thermostat/switch. Would easily get 5 stars if they used some better supplies because the radiator is beautiful. Be prepared to spend at least another $50+ to get everything right. ... show more

    • Fits 86 c10
This is a direct replacement for an 86 c10. The stock brackets do fit over the radiator somewhat but you may have to bend them/fabricate a small mounting tab if you want something to screw into. You’ll need to order the pigtails for the fans if you want a direct plug and play or you can use basic electrical spade connectors to make it work. Keeps the truck cool, doesn’t leak, it’s well built for the price. Would buy again for a cheap build as opposed to a $1,000 option ... show more

    • FANS DON'T KEEP ENGINE COOL AND FILLER NECK IS TOO CLOSE TO CORE...CAN'T USE ORIGINAL MOUNTS
Well, there's 2 main things....the cooling fans will NOT keep the engine cool even with no A/C and before someone makes a stupid comment, it's wired properly...pulling air through. Before the radiator, I installed a new water Pump and 180 degree thermostat. When trying to install the radiator, I quickly realized that the filler neck was too close to the core not allowing the hold down clamp to bolt on. I flip-flopped the mounts and still had to modify the one by the neck so the cap would go on. That would of worked if the fans did their job. What's the next thing to do....remove the fans and install the original clutch fan along with fan shroud. YOU CAN'T because the upper part of the fan shroud bolts to the hold down clamps. You can't install the left hold down clamp because of the filler neck!!! One other minor thing is the tanks are a little wider than stock not allowing the isolators to fit properly. ... show more

    • Just a bit of modification
You'll need to know how to wire the relay. Info can be found on the internet with a search for how to wire electric radiator fans. It's about 1/2in short so very slight modifications needed. Good product. Comes with a radiator cap!

Review Image by Doomus the Destroy-atator Doomus the Destroy-atator
Installed in my 1985 C30 with 454. Keeps the motor cool and looks good as well. However, be aware that the radiator is 1/2" shorter than stock size, this was solved by doubling up the bottom isolators. The hold down had to be trimmed slightly to accomodate the different radiator cap location. There is a wiring harness included, my previous review said it wasn't. It arrived 1 week later in a separate package. No markings on the sender to indicate temp range, but it would be safe to say 185 on and 175 off. Includes sender, 30a relay, fuse, fuse holder, eyelets and connectors. Good value, function, and looks overall. ... show more
