DIY: electric water pump install w/ pictures - Page 4

SSFenris · 01-06-2009, 09:17 PM

ok, the tool that the OP 'made' is called a ball-end hex key. You can get them in either allen "L" style, or in socket form (last I knew, they're offered in 3/8" drive). I have 2 sets made by Bondhaus, one with 'standard' length short sides, and one with 'stubby' short sides. I want to say they cost me about $49 for both sets, with sizes from 2mm to 10mm, with all the common sizes in between (2, 2.5, 3, 4, 5, 6, 7, 8, 9, and 10, IIRC).

CB, the EWP is no more of a risk on the street than your stock water pump, IMHO. If your stocker locks up, you get belt squeal, possible thrown belt, and pieces of shrapnel everywhere. If the EWP locks up, you'll eventually get a CEL from overtemp. I've had that exact question myself, and asked around to people that actually run theirs on the street. Most guys up here in the North will pull their pumps off in the winter (when the car is safely garaged) and check them for free rotation, but it's really not necessary. I have known guys that run EWP's, and have for ~5 yrs without any issues... and some that have run them for less than 1 yr, and blew up their motors.

Great write up.

So how exactly do you go about programing the Aeroforce to flash the LEDs if let say the temp goes over 230? I would like to do that as well.. It is hard to miss those when they flash at start up.

Nice write up as well...

I assume you had a coolant temp sending unit installed. Where was it installed? I've heard of some people putting it in the middle of the rear freeze plug on the drivers side.

i just monitor the head temp, there is a coolant temp also on the aeroforce,some say it dosnt give an actual temp but i find that strange because the temp does go up and down when it gets hot and cold. i think it still fits my needs to know when the car would be over heating, besides the head temp does work and thats good enough to know when its over heating.

Nope it reads off the OBDII port for coolant temp and head temp. I was just double checking on the way in this morning and my coolant was at 197 and my head temp at 206. They do move with each other so I would have to think these are actual temp readings.

I read in another forum somewhere that the coolant temp reading isn't an actual reading but an algorithm that uses head temp and some other factors to estimate coolant temp. I guess I'll just use the head temp when entering my coolant temp in the log book when I'm racing.

i have heard the same thing, im not 100% sure one way or the other. I always monitor head temp and sometimes the coolant temp, it does go up and down but not always together. some times the head temp and coolant temps are 5 degrees apart and other times they are 12 degrees apart.I did notice a temp sensor of some type under the intake when i did my cmdp, im guessing it was either a head temp sensor or coolant sensor. they also made alot of changes between 06-07 on the coolant system so maybe the 07 has a coolant sensor???

First of... i wanna thank you for the awesome write up!!!!

I just wanted to ask... in your instructions you say that you took the black wire from the pump and grounded it. Then you took the blue wire from the pump and routed it behind the alternator.

My question is; do you have to cut the wires from the black connector? If so... what do you do with the blue wire?

I'd really appreciate your help with this as i'm actually doing the install right now!

THANKS!!!

sorry for getting back to you so late.i was putting a new turbine housing on the turbo.i still have the connector,run the black to a ground,i used the bolt on the front of the timing cover and run the blue to your 12 volt switched relay,the connector sits to the left of the driver valve cover if your standing in front of the motor.

you can see the connector in the top of this pic.
