well, ive wanted to run a electric waterpump for awhile, but i couldnt justify the cost.. esp when all of my waterpumps (including my extra backup ones) work perfectly...


i just came across one so im going to be putting it in.

now i know this belt routing will work, even without the idler pulley. ive run it from the PS pump to the crank before, and it doesnt slip at all.

my setup would be the last two.. from crank, past where the smog was, to the AC, then tensioner, then alt, then PS back to crank. by going around the waterpump area completely, i can stick a elec waterpump there.

 

DUDE 1,

When I first saw the topic line, I though this was another one of those "Radiator for Volkswagen Beetle" type threads. Then I remembered that some electric coolant pumps are simply an electric motor conversion. Then I realized that you might be talking about exactly what you are.

It seems you've already done your homework. I'd vote for the last example, but I'm not certain how/where you would mount that last idler, since the timing cover just isn't that substantial or robust. You'll also want to maintain a reaasonably large diameter on the idler, or you'll have ridiculously high RPMs on it and need a high-precision, partial compliment bearing for it.

 

lol, honestly, i messed up when i did my smog pump delete the first time, and i had it from the alt, to the water pump, to the PS pump, then the crank... and it never slipped. so i dont think it will be a prob.

however, i was thinking... why put the idler there? it would be packed and not wrap much more anyway.... so i came up with this idea:

now the idler isnt to scale, but basicly, its as large as it can get and as low as it can get without the belt hitting the pump or itself.

for mounting, it can use a very simple bracket thats bolted to where the smog pump was.
