Who says us V6 guys cant have an electric water pump?

[inh]

Granted it may be a bit pricey, and you'll probably have to fab up adaptors to bolt to the block and give you a threaded fitting for a hose, but even given my limited machining experience, it wouldnt be too hard. A bit pricey, but not as bad as other pumps out there, plus you can order replacement motors for this should it ever die: http://store.summitracing.com/egnsearch.asp?N=115+400179+307491&autoview=sku

You can replace almost any mechanical belt driven water pump with an electric? Who said you cant use them on a V6?

I personally dont trust them for what I use my truck for (towing, long trips, 4x4ing)
unless of course you buy two...

You will have to plumb and wire it no matter what engine its going on, 4,6, or 8 cyl

Well from what ive seen, most electric water pumps, or at least those that most people visualize when thinking about them, are the kind that bolt on to where the stock pump does, and has the motor contained there, so it almost lookslike the old one did with a motor instead of a pully there. unfortunatly no one makes a pump like that for the v6's as far as i know, so when i saw one that you could plumb using hoses and mount the pump wherever you want i was a little excited.

Could you fix that link? It only showed MSD modules, carburetors, battery boxes, and electric fuel pumps.

 

[410Fortune]

Oh I see what you mean now
I was talking modify the block or the factory pump housing to work with an electric
but you found a bolt on electric pump for the 4.0L?

 

[inh]

sorry about the bad link, its fixed now. and not quite 410. i think we would have to make adaptors that would bolt on to the blocks water ports where the old pump did, and allow the threading in of hose fittings, and then run the hoses to this pump mounted remotley.

 

[BrooklynBay]

This is an actual pump with 1/2" fittings:

and here is another one that is a little different:

 

[inh]

yea. just make some blocks theraded for half inch fittings that bolt on to the engine water ports from the hold pump, run some hoses, and instant eelctric water pump! not to mention if it were to fail you could swap it out easy peasy.

 

[Afboy143]

what kind of power would this give? Would it justify the price tag?

 

[inh]

I doubt it. But im sure it helps a bit... Would also make tranny flushes a lot easier

Im hoping that with something like this and an electric fan i can get back a decent amount of power, and having an electric pump and fan that spin at full power all the time, regardless of engine RPM shoudl prove to be handy while offroading, as im lucky to get it up past 3k

 

[410Fortune]

Skip the waterpump, just do the E fan.
Not worth it IMO on a 4.0L, the factroy pump is a good unit.
Also you will have to re-work the serpentine system as well as plumb the hoses for teh e pump to the block.

E water pumps are for drag cars and street racers IMO.

What's the benefit of installing an electric water pump?

 

[chriswells78]

The factory pump uses engine power via the drive belt in order to spin the impeller and pump water. An electric pump frees up some of that power by using electricity already produced by the alternator to pump water through the block. The benefit is increased HP and torque, the downfall is more drain on your alternator or the need to buy a higher output alternator.

 

[410Fortune]

AND electric pumps are not as relaible or long lasting as the factory mechanical unit, from what I have seen.

Ditto, forgot to mention that.

I have mostly seen them of strip cars, never on a truck.

 

[410Fortune]

alot of newer cars have BOTH. Volkswagen VR6's are NOTORIOUS for the $150 part leaking....it is a booster run inline with a mechanical pump!

AND electric pumps are not as relaible or long lasting as the factory mechanical unit, from what I have seen.

I have a Meziere electric water pump on my '04 Mach 1, and it's rated at a 10,000 hour life span, so the lifespan isn't that bad. I've had mechanical pumps go in 35k before. As for reliable, it's very reliable. There are several people on the Mach 1 board with Meziere pumps that have in excess of 25k on them with no problems. I only know of 1 Meziere pump that failed prematurely, and it was replaced under warranty.

 

[inh]

The Meziere are certainly nice. Looks like the best lifespan thier remote pumps getis 3000 hours though, which i figure would last about a year, probably a bit more. Its a tough call really. I want the pump, but spending $300/year for it doesnt sound too attractive...

As for the isues with the serpentine belt, I could just take out the guts of a mechanical and use its pully, and drill and tap the housing fro the remote hoses

I still doubt if you can get any hp gain from an elec water pump. It's not the case that the electric motor is just using energy that the alternator is already making anyway ... the more the electrical draw, the heavier load on the alternator. The heavier load means the alternator is harder to turn. The extra energy to turn it comes from the engine. So you can either use the engine power to directly turn the mechanical pump and be done with it or use the engine to turn the alternator harder to produce more electricity to turn the electric motor to pump the water. Alternators are pretty inefficient at converting mechanical energy into electricity ... electric motors are notoriously inefficient and converting electricity into mechanical energy ... if you don't believe it, lay your hand on your alternator or an electric motor after they've been running, that heat is wasted energy. I have no doubt that you'd hurt your mpg.
Sure this would be an excellent choice for a race car where you can just drain the battery during the run and stick it back on a charger between races but not for daily driving.

 

[inh]

Actually you may be mistaken as far as ineficiencies. Man i cant spell... Motors, with propper controllers, can get 90%+ efficiency, and im sure alternators can do the same. Its just a mater of design. Not trying to argue, just throwing out my idea. Even still, ive seen documented cases (wish i could cite sources but i cant) where an elecric pump did in fact improve power. Not to mention it'd be a lot of fun and kinda cool to do
