electric fan conversion/heater hose question
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?

Re: electric fan conversion/heater hose question
I think you are looking for something like this? It is a Campion kit.

Re: electric fan conversion/heater hose question
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. (see https://www.therangerstation.com/tec...tric_fan.shtml)

Re: electric fan conversion/heater hose question
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.
