New Electric Hydraulic Power Steering Pump (EHPS)

[dsatchell]

A lot of the threads that discuss replacing the standard power steering with an electric hydraulic power steering pump almost always use one of three models: the 91-95 MR2 (no attached reservoir); the 2000-200? MR2 (with an attached reservoir); or one that has been imported from Europe.

The problem is that the MR2 versions are getting hard to find and can be expensive even used and having a part that is only available as an imported item from Europe is plain scary.

A new alternative that I have recently found is that the 2011 3.6L Dodge Durango and the 2012 3.6L Jeeps now come with EHPS. I can't find any other info about them other than a couple of pics in the Jeep. They are a little expensive but not more so than the EU models and they are practically brand new and they should be available for quite some time.

Has anyone got any additional info?

David.

Please post the pictures that you have. I've seen a few stateside cars that come with EHPS from the factory, but they had the system built into the rack and column, so it made it impractical to use on a different vehicle as a universal system.

You really didn't need to post in half a dozen other threads before doing your research.

The mazda 5 uses a EPEP system too. However they are not cheap and I didn't know anything about them. Well that is not totally true. I have a 5 and they work great. I just didnt do any research since the clio pump was cheaper and is proven to work with the setup I'm going to use.

Availability and pricing will probably be similar to the MR2 for a while until more Durangos hit the salvage yard. Pricing new is pretty steep. But it might be nice to have another option. Wish the Renault was sold here so we can get the pump that Andrew Brilliant went with.

What renault was it from? As i can get parts from them very easy, i use to own a renault clio williams, they are always being scraped here. Let me know and i might be able to locate some of them.

 

[dsatchell]

this is the only pic I have been able to find and from what I have read so far they are saying that it will only be in the 3.6L V6

the Renault is the Clio from 2000+ with the reservoir on top...there is a pic of it in one of the other threads

Oh please do let us know. I'm sure there would be several here who would want one.

I just ordered one of the 2011 Jeep Grand Cherokee Power Steering Pumps so I will post some images when it arrives.

The think I'm concerned about with the Renault pump is the reservoir getting damaged or the pump going out and being unable to get a replacement for several weeks.

How much did that set you back?

Anyone thought of fitting an mkv electric steering rack?

 

[greengoblin]

Switching racks opens up a whole lot of other issues. I toyed around with the thought of using an evo rack and scrapped that idea because of all the cross member modification.

Also how many wires does the jeep unit use? Amps? details details details.

I shall use this pic as reference, will it need to come with the ecu for it or just on its own? I shall try find them with wireing then so its easier to wire in,

Well i just had a basic search and wow get your wallets out guys, cheapest ive found is about £200 or $300 so i think im going to have to phone akd visit some scrap yards and get something a little cheaper , what kind of price range am i going to be looking at here? Is 300 bucks to expensive?

I will keep looking and see what i can find out for you all

This is what I ordered online:
Name : 2011 Jeep Grand Cherokee Power Steering Pump
Description : 3.6L, ELEC, P52124998AF, 3.6, Automatic Transmission, 4X4
Price : $126
Condition : 5 stars

For that price it was too good to pass up even though I'm not 100% positive that it is the correct part. I also don't see how I could be wrong but the problem is that I called a part locator about a 2012 pump and was quoted $600.

What I don't have is any details about connectors, wiring, specifications, layout, or anything else.

Don't forget that anything that comes from the EU will have around $75 in shipping.

WOW, That's cheap (used) compared to the mr2, Maybe because they are not that popular, However, they both cost the same new.

What about direct electric without hydraulics? (not for this price tag though)

These are super expensive from the stores even recon units are mega money!!! I think i need to stop looking and go to the scrap yards

 

[dsatchell]

The pump arrived today and i took some quick pictures (I'll replace these with better pics later). I also found a self study guide from VW about EHPS that discusses the steering sensor they use and the mechanical vs electrical power savings.

It's hard to make out in the last two pictures but I believe the high pressure line connector is on the left side just above the control wire plug. On the right is the power connector with the hot (+) wire on the outside edge and two low pressure ports just above that. The low pressure lines are just held on with standard flat spring clamps but I didn't have time to check out the high pressure side.

How are you going to make it work?.
Did you get the steering sensor and the angle sensor that shows in the site?.

Interesting.

 

[greengoblin]

That looks like more work that two wires are two hose. This was one of the main reason I chose the clio/kangoo unit.

Anyone know what pressure our OEM unit produces?

The clio unit pumps out between 150-300PSI with no load .When loaded up it makes 1500PSI. Pretty sure that is plenty to run the rack and it you wanted the brakes too.
We may need a pressure reducer in line to keep from blowing out rack seals.
