Posted By: DeveK Electric Waterpumps for 235/261? - 03/05/19 03:14 PM
Does anyone know if there are Electric Waterpumps available for the 235/261 engines (1954-1962)?

I have a waterpump article (http://devestechnet.com/Home/WaterpumpPrimer) and want to include this information if there are any available, or any that could be modified.

Thanks!

Hi DeveK . . .

I have never seen a bolt on electric pump for this vintage of Chevy or even the later inline sixes for that matter.

Down under they use a block-off plate to plumb a remote pump: AussieSpeed

DeveK,
Do a search for remote water pumps. Meziere, Allstar, Warner all make remote ones. They range in price from around $160. up. My friends have one on their Falcon, (believe it's a borg warner thats about the size of a large grape fruit They have used it for several years on their turbocharged 250 and seems to work fine.

Electric pumps have high current draw, most practical with an alternator.
They also allow something otherwise difficult to do: separate the fan speed from the water delivery volume. Normally these are in lock-step because they're on the same pulley.
You can get some free power and reduced noise by slowing down your fan by using a larger pulley or smaller damper.

What would be ideal is if we could find an electric waterpump that would not be hard to adapt to our engines. Maybe elongate holes, or make an adapter plate or something that isn't over the top.

Using Dave Folsom's waterpump adapter plate on an AD puts the waterpump back in the middle of the radiator where it belongs. That is a no-brainer. I do that everytime I rebuild an engine. So a way to use that with an electric one would be something I think would be worth looking in to. I am one of those who start with 12 volt 10 or 12SI alternators as a baseline.

Thanks for the replies. I still think this is a good idea, but not sure where to start or what to order that is possible.

After i upgraded to a new aluminum rad i took my fan off as it cools so efficiently. I do still have a electric unit on the front of the rad so you dont see it when looking into the engine bay. The fan is set to kick in at 185 and one stays on for a short time in stop and go traffic.

This might be a dumb idea but could you just take the guts out and plug the shaft hole and use an inline electric pump? I thought about running the mech. pump and having an inline electric pump to cool between races or to avoid the "heat sink" effect but Meziere said I would have to run the electric all the time. An electric kind of scares me on long trips unless I had a spare. The mech. pump I can buy anywhere.
