2007 Electric Water Pump Conversion [Engine's]

A replacement Aisin WPT-190 electric water pump for the Gen 3 costs about $300. Not bad but still 7x the cost of a replacement WPT-111 on the Gen 2. And what if the harness rusts? More moolah. Hopefully Toyota waterproofed the connector on the electric water pump much better than it did on the HID leveling sensor on the Gen 2.

Chanelling Mr T: I pity dah foo who needs to replace his electric water pump!

 

the way im going to look at this is that the $459 price tag, is not that much more than a dealer would charge to replace a water pump, so thats why i will consider this an option if the need arises in future.

amazon shows price of $337 where you price yours

 

i completely agree with the money issue, but when it comes to mods, most p chatters are too timid to tackle something like this. we prefer bumper appliqués!

 

desire is exactly right, all the best!

 

if you have a 10mm wrench, a drain pan and a razor blade, you can do it yourself in an afternoon. very easy water pump. or was it a 12mm...?

 

maybe. but all you need to do is put it on stands, take the rf wheel off, take the plastic liner out of the wheel well, if I remember correctly, the pulley has 3 10mm bolts holding it on the pump which you need to break loose before you slide the belt off, (might as well get a new belt too), 4 bolts holding the pump on. don't forget to drain the coolant into a pan before you take the pump loose. should be a drain valve on the bottom of the radiator. gently and carefully scrape the old gasket off the block. do not gouge the metal or the new gasket won't seal. do not over-tighten the bolts-- they'll break easy if you get ham-handed. when you go to fill the radiator back up, it may take a while for the cooling system to burp all the air out of the heater core. you'll get a red triangle and gurgling noises and such. you don't want to drive it until its burped. I always turn the heat on full blast and run the engine until it gets hot in the car, making sure to keep an eye on the radiator. patience is needed cause some cars don't want to burp, and even the dealer sometimes doesn't get all the air out the first try.
been about a year and 1/2 since I did mine, so I might have missed something (old brain don't work too good any more).

 

You might be able to use one of these to control the water pump.
