Power Steering filter Location 02 Sable Vin:U
Okay so I have a 2002 mercury sable gs sedan with the 3.0L OHV and the AX4S Transmission. I need to know where the power steering filter is cause I just replaced the pump so want to start fresh. I googled it and it brings up only two things one which is in the low pressure line which mine doesn't have and the other is in the high pressure line but when I read details on this it doesn't have anything saying it is actually a filter. Please help I need help so this pump doesn't get messed up.

If it has a filter it will be in the low pressure line. (return line) All cars have a low pressure line. It's the one that goes from the steering gear back to the cooler (if it has one) then to the tank for the fluid.

Hint: high pressure lines will have threaded ends and low pressure lines generally have a hose clamp. Just follow the line.

I know where that is but I have looked all over even without the engine in the bay. Nothing, no filter but they do make one you can put it in. Do you think it would be a good idea Rupe? I trust your opinion.

It can't hurt unless you forget it's there and it clogs. OTOH, if it clogs then you have bigger fish to fry anyway.

The main concern with PS fluid is not like oil in the engine. There is no contamination from fuel, etc. The two items that do bother it over time are heat and moisture, which makes the fluid dark in color. IOW, it's worth changing / draining / flushing in the long run, even though most people don't do it. The easiest way is to just disconnect the lowest possible hose and let it drain into a bucket, refill, run the engine for a minute, drain again. Alternatively, if you can easily find the end going to the remote tank or cooler then you can route that into a container with a piece of hose, run the engine for the 30 seconds or so till it spits air, then flush with a quart of fluid a second time. Either way just reconnect everything and refill. Most systems only hold a quart or so, which means you may go through a grand total of 2-3 quarts including a flush.

As I said, it can't hurt. I have used them over the years and some aftermarket equipment specifies you MUST install one or their warranty is not valid.

As I was hinting at before, it's key to start with fresh fluid.

I have seen many steering pumps with the filter inside. On large trucks and equipment it is replicable, but in most cars it isn't. As Rupe mentioned, if the filter clogs, you have bigger problems.

Thanks for using the forum,

RE: Power Steering filter Location 02 Sable Vin:U
Okay so I already have it drained but would it hurt to blow compressor air through the power steering system to make sure I get all the old ps fluid out? I will see if I have a place that the filters could replace a lined area. Most likely no though. Most of the low pressure line is metal because I goes under the car and the little bit that isn't in a tight area on the car gets really close to the exhaust manifold.

Probably wouldn't hurt but compressed air will make a mess in the garage. (spatters all over) Placing a hose into a bucket and flushing with another quart of fluid is cheap. When it comes out clean you have done the job!
