Are there any write ups on installing an electric waterpump, and how would yall rate the difficulty level. I guess it doesnt matter how hard it is Im going to tackle it this weekend. Just I guess any tips or good advice would be greatly helpful. Car is in sig

 

I can do a write up later tonight. I installed a Meziere on mine. The REAL
trick is to take your water pump to someone that has a press (if you dont
have one) and get them to press out the impeller and bearings (I paid the
guy $10 to press the stuff out).

After that, you install the freeze plug and re-install the water pump housing
(to the engine). Next, bolt up the electric pump and wire it up. You will have
to "alter" the fan shroud housing, otherwise the pump will not fit.

It's actually pretty easy. I'll take some photos of mine later and post it.

 

Ok thanks I really appreciate it.

 

Hey Guys, Ive been doing some research and found alot of problems with the mez that I thought I was about to purchase, but the posts were very old. Should I not purchase it or get a different brand and I saw something about cutting up the fan shroud, does any one know what that consists of.

 

Yea, you're reading old stuff. All the other competing brands had issues too.

About the fan shroud - you're NOT removing that much. Here's what I had to
remove from the fan shroud (compare that with your shroud):

It's not that big of a deal. Give me some time to do the write up.

But let me ask you a question: Why do you want to go electrical?

 

Get the Summit Racing brand... it's actually a CSR... very nice unit.

tip: use the GM water pump gaskets... the Felpro ones have round bolt holes (instead of GM's triangular bolt holes which hold to the bolts better).

tip: use sealant on the bolts

tip: make SURE you get the pump's positive and ground wires correct... reversing them while assembling the connector will make things real bad. :-o

tip: watch the radiator when you're pulling the fans and messing with the pump... bending the fins will decrease air flow.

tip: check if you need any new hoses... now's the time (I prefer the blue, long-life Goodyear High Milers). Same goes with a thermostat.

tip: bypassing the water pump relay once it's installed can run the pump to speed refilling of the radiator.

tip: bypass the TB if you havn't already... it's one less hose to mess with.

tip: do NOT, under ANY condition, switch the two hoses that plug into the radiator above and below the thermostat.... if you do you'll dump your coolant out the steam tube into the overflow container! (seen it done on two engines...)

tip: do NOT fill the system entirely with coolant... 50/50 with water please. I know that sounds dumb... but yet again, I've seen it happen. I can only assume the guy THOUGHT he was filling up with that pre-mixed 50/50 blend you can buy instead of full-strength coolant... but seriously it was like thin corn syrup.

 

How much HP is an electric pump worth?
How long do they last before you have to replace them?

 

I just installed a Meziere EWP. Very high quality piece IMO. The guys on the Impala board swear by them. The ewp is worth ~8-10rwhp.

 

The install itself isnt too bad... getting the impeller out is kind of a pain as said before

All you really need is a hammer and punch and cant be afraid to hit her pretty hard (Air tools help a lot)

 

thanks guys. the only reason I want to go electric is for the horsepower and ease o fchanging in the long run. I was replacing a fog light bulb and noticed my weep hold had opened up so i need to get this done before it ****s on my opti. i figure since ill be doing the w.p swap anyways i might as well pick up a few more horsepower. caldercay thanks for the pick, it also helps that you got the exact same w/p as i have just ordered. how do you like your decision.

 

There is a write up somewhere in this subforum..i used it to hook my EWP up using my A.I.R wiring since I was eliminating that. Works great!

 

8-10 sounds generous.

 

True, this link only shows a 6.2 peak hp gain.

It all adds up though, for people that don't want to dig in their motors.

If you're going to DD the car, make sure to buy or build some kind of a warning light.

 

Im going with CSR pump because it draws fewer amps.

 

Anywhere from 6-10hp. But it adds up if you're doing a number of mods.
If you're ONLY doing the electric pump and nothing else, it's not worth it
for that reason. It is nice to be able to easily replace the motor, though.

The 43 GPM Meziere is advertised at 2500 hour lifecycle:

... and 3000 hours for the heavy duty (55 GPM):
