Electric Water Pump

[Vettelt193]

Anyone use an electric water pump?

I found this one on ebay: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7915790700&category=33604&sspagename=WDVW

it is $170.

A) is that a good price?
B) my current pump is leaking, will this fix it (I assume it will, considering it replaces all the internals)
C) how hard is the wiring?

also, is it worth it? I have wanted to do this for some time, for the extra power it could make. Any opinions?

Water pump is leaking..... Fix it fast or prepare to be left roadside because it will ruin the optispark. Also, consider changing the optispark while the pump is out. If it hasn't been changed it will eventually.

Sorry, didnt realize you posted a reply to my thread. You got lucky... I was roadside by construction and to boot it started pouring rain. A mud hillside washed down and the car which hadn't been wet in 3 years was up to rims in mud.

good luck

That stinks! Hope all is ok with your 'vette!

no one uses an electric pump?

I have an electric wp on my car....Mezeire Heavy Duty unit. They have a good reputation and several advantages over mechanical pumps that are only mediocre on LT motors anyway.

- Always pumping at peak performance , not just when revs are up (so at idle you are getting more flow

- Frees up ~5+ hp, because engine is not having to run it

- Not really expensive.

- Pump can be turned on when engine is off to continue cooling

Good choice just be sure to keep a spare fuse in car at all times . Not a bad idea to rig up a light to come on when pump is not getting working for daily drivers.

Can you give me a quick run down on how you wired yours, and how hard it is to wire?

I know of several people on the forums that run the Meziere HD pump.

I personally choose against it when I did my heads cam.

My reasoning: when I asked around, virtually everyone who had one had had an experience of some sort where the pump when off line, they were on the side of the road or at a gas station, trying to fix a wire or fuse.

So if you get one, it'd be wise to watch the oil/water temps like a hawk. Unlike the mechanical pump, these don't go out gracefully, they just stop when they have a problem.

I did not want to watch that gage that close.

Thanks... maybe I will just get a regular pump. It is starting to seem like more trouble than it is worth

I have heard of some instances when the pump fuse did go ..... but they are relatively few. If I was going to daily drive the car and put alot of miles on it I would consider the mechanical . If you dont drive as many miles and are more concerned with performance the electric is the way to go.

You can wire in a warning light easily that will light when power is off to the pump eliminating the worry, I know there is a complete write up on install and this light but cant find the link......I will keep trying.....

Thanks...

My LT4 has less than 50k on it, but it used to be my second car. After realizing that I didn't enjoy it anymore, I got rid of it... then bought it back again for my daily driver. I now enjoy having the car, like I used to enjoy my '87 and '93 when I had them...

My second 'car' is a Harley.... While it serves as a backup if the 'vette breaks, it isn't that much fun in the rain

With everything I have learned, it seems that I should just keep the mechanical pump... even though it seems economically stupid to me (I can get the electric pump for less than the mechanical, AND get the HP gains from it... I assume it should help gas mileage too, even if only a little)

So far, I have been deciding, and the 'vette has been sitting... I haven't driven it in almost a week so I don't blow the opti too!

Make the decision easier....get the electric, get a few extra fuses and have the LED or light wired up . Then you will know if its working or not and have a spare if the fuse goes.

They really are quite simple and as you may know electric motors like this are very reliable. I know of several folks using them for daily drivers . There are other sites that have install info on them check em out.....

Corvetteforum.com, digitalcorvettes.com, Z28.com, etc. you may have to search a bit but its out there.

Hope that helps....

I searched around a bit... some positives, some negatives... I still am undecided though... another night of thinking i guess.
