View Full Version : powersteering pump

02-26-2009, 10:46 AM
im tired of the belt driven powersteering pump that always leaks. it seems like every celica has this problem, so i cooked up an idea. What if we incorporated the mr2's electric powersteering pump within the engine bay of the celica, it should work right? i mean, its just simple electronic circuits. Has anyone ever done this before? Anyone have any ideas of the electronics that is used to run the pump?

I was gonna replace mine with an electric pump from a MR2 but decided it was better to just keep the belt driven pump.

It would have been more expensive to grab all the parts from a MR2 than to get a replacement pump.

I would have needed the pump, the controller, the steering sensor, and I forgot what else.

well it depends on where you get the pump, controller, ecu, etc. i found acouple of mr2 at the junkyard before, just never thought the mr2 ran an electric pump. I could just replace the pump itself, but it is a b***h getting to it and removing it. i don't even want to mention the space you have to work in. plus, its so tight that you cannot fit a wrench in there to remove the bolt that holds hose to the pump.

didn't know the mr2's had an electric pump. This is a great idea. I would be very interested except I recently replaced my pump and high pressure hose and its not leaking any more. Anxious to see how this pans out.

Could also order the seal kit from your local dealer and redo your existing pump.

Anybody tried it yet?

You can do it, but I recommend trying to use the steering sensor and the ECU too rather than having it on all the time. Reason is, it eats up a LOT of electrical load.

Where is the steering sensor located in the set up?

In the MR2, its in the steering column.. Yank the wheel, and its down there somewhere..

does anyone know if the aw11 mr2 come with the same powersteering setup? there are plenty of those in junkyards...
