Electric power steering pump

[Luckyone]

Are there any down sides to fitting an electric power steering pump?

Having a fully charged battery, when coming to start it in cold weather was always a problem, but I guess when the electric pump is running & the steering is not being used it won’t draw too much current, so there will be plenty left for charging the battery. I found the thread about setting it up so it’s not on when cranking, that sounded good.

Is it best to remove the old pump? Or is better to leave the pump but remove the drive to so the pump body is still bolted to pump assembly offering it better support?

Mine is ok, although the seal looks like it may have been leaking. I’ve got enough to do putting the car back together, but it makes sense to get jobs like this out of the way in the process.

AFAIK you can't remove the original pump or the drive to it. It is in a stack with the oil and water pumps, the whole stack is gear driven directly from the crank.

My pump is on the floor at the moment, not hard to get off with the engine out. But the pump does form the end of that stack so for the long term I was thinking I’d be better putting it back just with the drive removed.

It was removed from the stack on mine. No idea how the drive was secured or altered to fit afterwards.

Aha! I had thought, off the top of my head, that it was the middle one of the three not the end one.

My original pump is in the skip, electric PAS pump working fine and no issues with the other pumps.

You can remove the mechanical one, it's driven by a shaft with a woodruff key. I needed to undo the drivers side engine mount and jack the engine up slightly to do it. The electric pump on mine is controlled by a switch, you only forget to turn it on once!

Thant’s useful, thanks guys.

Very interesting you did got yours off with the engine still in, I’d never had the need to try but had heard quite a few times it was an engine out job. Makes me think twice about doing it just because the engine is out…

my pump was removed with the engine in place, just a little fiddly.
