electric fan conversion/heater hose question

[68isgreat]

For my 68 C10, I'm considering converting my 1990 tbi 350 to an electric fan, but my motor doesn't have a water pump heater hose inlet, and so I have the return heater hose connecting to the top of the radiator next to the battery instead. My radiator is from a late 70's square body. None of the radiator/electric fan conversion kits I see have an upper hose inlet on the right side near the battery. Does anyone know of a workaround for this? I think I read somewhere about a spacer under the thermostat with a nipple attached. Would that work in lieu of connecting to the radiator?

I think you are looking for something like this? It is a Campion kit.

Yes! That's it, thank you. I'll look for one of those.

I may be missing something but are you just wanting a radiator with a heater pipe? My '83 K20 had that as stock with the 350 version of the radiator. Then I upgraded to a 454 radiator and it still had the heater hose inlet. They are also available with oil cooler provisions. I have dual Corvette C4 fans on mine

(see https://www.corvetteactioncenter.com...bfh/bbfh7.html)

I have TunedPort fuel injection on mine so the ECM controls both fans. If you have TBI I believe you can control at least 1 fan with that ECM. Alternatively you could use a BMW sending unit with a Volvo relay to control a 2 speed fan.

Yes, that's all I'm looking for. Although I just took a closer look at my water pump, and it does have a hex plug that I could add a heater hose fitting to. That said, if my TBI computer would only work one of the fans, I'm not sure that's something I want to get that far into the weeds with. Thank you for the input. Definitely something to consider. Hmmm...

If you leave the water on the radiator you get warm water for heat faster in Winter. It's kind of nice if you use the heat much.

Good to know, thanks! That is definitely a consideration.
