Help identify leaking engine part (pic)

The big metal piece in the yellow circle looks like either a A/C compressor/pump or a power steering pump. Not sure how that plastic piece attaches.

Is it engine oil, ATF or brake fluid that is dripping ?

Looks like the pressed in return line connector for the power steering.
I would use some power steering leak stop, before tearing it apart.

Yes, what kind of fluid are we leaking?

I believe now this is the power steering pump.

How safe is power steering leak stop to use? Is there any risk to damaging anything else by using this type of product (will it gunk up anything else???)

If I have to replace the power steering pump, any idea how much that would run me (ballpark)? Just trying to figure out if it is an easy job or hard (time consuming) job for a mechanic.

Thanks!

I've got a slow leak underneath my engine. This is on a 2015 Thor Majestic 28a with a Ford e450 Superduty v10.

Here is a picture of the part (circled in yellow) and where it appears to be leaking (circled in red). It is taken from underneath the vehicle.


Can you tell me what part this is? If I trace a hose going into it, it looks like the hose is coming from the brake fluid reserve tank.

After driving for a couple miles to warm it up, and then parking with the engine off, I see 1 drip about every 30 seconds or minute.

Figured some of you experts out there will be able to tell me what this is, and what the likely repair will need to be.

Thanks!

Can you get an upclose pix of the PN stamped on the side?

That PN should be searchable and give you exactly what it is..

I suspect that IS your power steering pump which would be located down low on the drives side of the engine.

Ford uses a remote reservoir tank for power steering pump, should be a dipstick you can remove from the reservoir which will tell you the fluid PNs recommended for use with that reservoir..

While I not familiar on the exact layout of E450 van based vehicles, the brake reservoir is typically mounted directly on top of the master cylinder and is not typically remote mounted.

This is a pix of the master cylinder that comes up when I search for your yr and model..





I suspect since it is most likely the power steering pump, you will be seeing a new one in your future.. Not sure if that item you circled in red would be available separate from the pump..

I would have to say this is probably the part you are after. There are also videos here showing the procedured for removal and replacement. Hope this helps.

I think it is a Motorcraft STP278 - Amazon $300.

I would not be afraid of using Barrs or l
Lucas Stop leak.

Not sure how small some of the orifices are on late model power steering racks. You may clog more than your leak by adding stop leak
