Electric Waterpump?
My water pump decided to clean my belt, pulleys, and cross member.
If I buy this electric water pump from summit, will it work on my LT4, or does it have to be added to an existing pump that is in working order?
Do you have to take the impeller off the old waterpump? I just don't get how it works. Can you please help a brother out!

Thanks Guys!

One of the guys here posted it in tech tips a while back. Long story short, it will work just fine, but it's a bit more involved install than it seems like it would be.

I wouldn't install an EWP by itself. Most of us do the EWP during a cam change. The EWP allows you to run a cheap SBC double roller timing chain setup, so it makes sense if you are in there to replace parts anyway. Otherwise, it's not worth it. An OEM pump will almost certainly last longer. My first EWP developed a bearing whine in about 6 months or so. I think that was a fluke, and the guys at Meziere took good care of me, but it does happen.

I know that Steve's MEZ went out quickly, however, he and I did the installs together so his EWP failure was not due to installation issues.

I've been running one for a while now, been real pleased.
The hardest part is finding a keyed electric source, and making good clean watertight connections.
Though it may have to be replaced with a stocker when I install the blower.

Yes, the ewp is a pain to install, but once installed, it's easy to replace should it fail. Mine has been running for about 20K. GM should have gone this route instead of the mechanical way.

You're not going to see a whole lot of gain, but there will be a little. Like Steve said, once you have it installed, replacements a breeze. Here is a great site with info on installing a Meziere on a WS6 with an LT motor.... http://www.ws6.com/kelley-wp.htm

Yes you can. The standard SBC after-market EWPs don't utilize the stock housing though, so they will cost more.
I've heard good things about the CSR, too. But for anyone reading this, understand that some EWPs are intended for drag racing only and won't necessarily provide the long life on the street that the CSR or HD Meziere will.

Well, just thought I'd chime in.
I replaced the water pump with a brand new OEM, and a few other things while I was at it.
Brand new OEM water pump.
Brand new Coolant temp sensor.
Brand new ASP underdrive pulleys. 22%Crank & 15%Alternator.
Brand new Dayco belt.
Brand new Delco Platinum plugs.
Flushed the raditor & re-fill with bottle of water-wetter, 1 quart of dex-cool, and the rest... straight up H20. Living in florida has it's advantages! But I planning on adding a EWP & a MSD opti soon, so Ill have to change it out again anyway. I also plan on installing Samco hoses, and finishing my AC elim. bracket! Right now my crusing temp is around 207 deg. and I know it will drop when that condensor is out of the way. I also want to add a bigger radiator with rest of it. Im developing a parts list! Wish me luck.
