Would the following procedure work in trying to get the tight tolerances with the divider plate?
What if you put constuction adhesive or JB Weld on the divider plate in a large amount that covers the entire area that the impellar almost engages,then spray the impellar with Pam or some other lube in order for the adhesive not to stick. With the water pump inverted, place the divider on the pump and spin the impellar. Clean off excess stickum. May have to repeat process, but nohammering divider plate or tugging on impellar. Saw McGiver do this one day while stranded on an island. Great imagination that McGiver. Now we will have 6000 more threads as to what salad dressing to put on the impellar. I love it. dave Last edited by davidgto; 07-31-2012 at 09:20 PM. Reason: mis spell |

Do they make one for a 11 bolt water pump? Looked the one up listed below and its a 8 bolt.

cant edit so have to repost, I know they make one for a 11 bolt but is it the same fin design? You would think so

I ordered the Cardone PWP381 pump. Opened it up and the impeller is a stamped steel one. It does look bigger or different so maybe it'll work better?

For those that are wondering if the Edelbrock 8856 Waterpump still needs the clearance problem between the propeller and divider plate: here is proof that there is still 1/4" of space. (I got this pump with the March Serpentine Kit and it is not reverse rotation like March says)

OK, I went to O'Reilly last night and they carry the stamped steel implellers only, where can I get a good cast one?
I bought an '81 TA with a 6X 455 in it and you guessed it, it runs a little on the warm side. It has an aluminum water pump with cast impellers but everything else checks out good.

Not sure what number was ordered but it was the only cast body that he showed listed. When it came in, it had a stamped impeller.

I bought a cast impeller pump from Spotts Performance quite a few years ago, but still had the cooling issues. This despite every other item chased down and improved. The one thing that fixed my problem was the subject of this thread, reducing that dimension carefully on the divider plate. Another happy customer, thanks a ton!

I don't normally like bringing up old threads, but why has this thread never been a sticky? Especially with it being such a common problem?

Gap closed up a lot
Thanks to a fellow member here, I got hooked up with an original water pump for my 73 Formula, with a cast iron impeller which looks pretty big, measuring about 4 3/8" diameter with 8 tapered vanes. I sent it out to get it rebuilt/overhauled. I called them first and explained what I was sending, and the topic of this thread. They said they try to set the vane at OEM specs, but it is hard to do with only half of the part. I told him I was going to send a divider plate with it, so the impeller would be pushed on only so far to give me a good tight clearance, they agreed that would be very helpful to them.
It took about a week, and they sent it back with the impeller almost touching the divider plate with no gasket, so with a gasket it will have as close of a gap as possible. When it finally warms up enough to be able to replace the one on the car right now with this one, we shall see what happens with the temps, and I will post back with my results. Otherwise here are some pics of what I got back. Pepi

Will do Charles, waiting for some warmer weather (we just got a little snow yesterday again), and for my foot to heal before I can walk out to the garage and replace the pump. But I will definitely reply back on how it works, and if anyone needs anymore pictures or information.
Thank you Charles for all you have been trying to do with Cardone to try and get them to supply us good pumps. I have been following this thread for quite awhile, and you just don't quit and give up. Huge thanks!! Pepi
