Reverse Flow Water Pump

[LSUpete]

I'm looking to replace the reverse-flow water pump that came with the serpentine conversion kit that I purchased from BC Broncos. The water pump is extremely rusted inside and I'm concerned about its performance. I could easily order a new unit from BC, but does anyone know of a BETTER product that could be used for this application? See photo of the current water pump.

FYI, it is not reverse flow. It would be reverse rotation. The flow through the engine is always the same direction. But a serpentine belt drive that runs the waterpump on the smooth backside of the belt is rotating the waterpump the opposite direction of the crankshaft. The waterpump spins the other way, but the flow still goes into the block first and exits the intake.

As for a better version, I don't have any advise on that.

Does bc still offer that pump? I remember years ago Chuck was having trouble getting his water pumps but that might've been a dual rotation unit or something.

As of many years ago, that was a one-off, available only from one supplier item. No idea if it's still offered or not, but to the best of my knowledge, no one else makes one.

What was different about it? Standard rotation housing with a reversed impeller maybe?
I bought one from Ford Motorsport/Racing but it looked different, with a different shape overall. Got it as an experiment, but never worked with it. Still sitting in a box after all these years.
Never even checked to see if it was meant to bolt up to a standard front timing cover, as found on a Bronco, or was supposed to be accompanied by a different one.

I think it is the Bronco style inlet (opposite side of most small blocks) and being reverse rotation.
Might have to run a regular port reverse rotation water pump and the crossover pipe to connect to the rad.

It's been a long time since I was interested in the details on them so my memory is a little fuzzy. As I recall, it's a standard rotation housing with an impeller shape that could be run either way - not optimized for either direction of flow.

That sounds more right. The Bi-directional waterpump. will work either way. As you stated, just doesn't work very well in either direction.

Have you looked into the water pumps from Tuff Stuff? They make a reverse rotation water pump with passenger side inlet. I purchased one for my Bronco from Summit Racing. When I ordered the serpentine system they did not have the pumps in stock so I went looking for one and found the pumps made by Tuff Stuff. Still working on getting the Bronco back on the road so I have not tested it yet.

What was your success with this pump? I also ordered I believe the same pump and it is too tall and created fitment issues with the fan and radiator. Maybe I ordered the wrong one! Thanks !

I decided not to replace it.....again. The one I have is three years old and its just rusting away inside. So, I decided to go in a different direction and simply convert to the Explorer serpentine system, and use a Flowkoooler aluminum water pump.

 

[RG75Bronco]

Could please give me a measurement from the back of the pump to the mounting hub when you get a chance? The pump I have is 5 1/2" and it is too long. Thank you

I am glad that you are doing this. But I have a question for you. I have been running cast iron small block fords since the 80's. I have never, not once ever...had any kind of corrosion whatsoever in my cooling system. I have seen a LOT of horribly corroded cooling systems...but I have never experienced it myself.

I am wondering what you use for coolant, and if you plan to use the same stuff in the future. You said that your impeller was "extremely rusted" but you didn't say what you are going to do to prevent that going forward.

Can you please post what you use for coolant? I would be interested to know.

I've always used Prestone Max or Platinum.
Going forward, since I live in South Florida and am not concerned with freezing temps, I'm thinking of simply using a combination of distilled water and "Water Wetter".

Do you have a 4 core radiator? Those are thicker then stock which will place it closer to the engine.

I am in the process of installing a new engine in my Bronco. All of the parts have been tested fitted on the Bronco. I recently removed some of the parts so they can be powder coated. So as far as how well it pumps and longevity it is too early to tell.

As for fitment I have an aluminum radiator and electric fan. It is a close fit but there is clearance between the fan and water pump. As far as I can tell a mechanical fan should fit without any clearance issues. All of the pulleys on the BC Broncos serpentine system line up.

This is the model I used: Tuff Stuff Performance P/N 1432CREV.

What are you using for the lower radiator hose? With the passenger side inlet, does it use a stock hose?

Correct. The lower hose is a stock Bronco hose.

What front dress are you running? Explorer, Mustang, or stock?

None of those. I am using a serpentine system from BC Broncos. It uses a 3G alternator (mustang) and is compatible with stock or Saginaw PS pumps.

I believe that BC setup IS the Mustang front dress.
