MrMagoo Posted October 17, 2015 Report Share Posted October 17, 2015 My FSM is out in my car, and it's cold and I'm too lazy tonight to go out there and get it. Thus my question is, is there a power steering fluid filter for my 1995 DeVille 4.9L? If there isn't, or if it's just a screen in the reservoir, I'd love to hear some opinions on an after-market in-line filter like this guy put on his Crown Vic: Link to comment Share on other sites More sharing options...
winterset Posted October 18, 2015 Report Share Posted October 18, 2015 I do not drive my '96 deville aggressively. Only thing i recently did was to use a turkey baster to suck out the old fluid, and fill it back up with fresh fluid. After a few weeks, i did it again. I figure a little fresh fluid will keep the system clean. I would not want to touch any part of the system and install a magnetic filter that is probably best suited for heavily used fleet vehicles. 20 years, and my entire system is original at 112k.

winterset Posted October 18, 2015 Report Share Posted October 18, 2015 Plus at the end of the video he is using transmission fluid in his power steering system. I used the clear gm approved power steering fluid to fill mine. Link to comment Share on other sites More sharing options...

MrMagoo Posted October 18, 2015 Author Report Share Posted October 18, 2015 I'm not going to put transmission fluid in my power steering..... I know about the turkey baster method, and I'll use that once I know all the old stuff is out, but I want to do a flush first, which is why I asked about the filter. Adding one in-line seems on the surface to be one of those "can't hurt, might help" things. I wouldn't do it for a while anyway, but I thought I'd ask while I was already on the subject.

barczy01 Posted October 18, 2015 Report Share Posted October 18, 2015 What you can do try to flush the system like a transmission with the car running. Hmmm a 95 Deville can you feed the pump with maybe a 2L cola bottle and disconnect the line at the filter? I think the filter is on the passenger side subframe held in by a 13mm sheetmetal screw.

rockfangd Posted October 18, 2015 Report Share Posted October 18, 2015 trust me from experience I do not recommend a flush. I stand by using the baster method for all models. I empty reservoir with baster, refill to level. once a month for 6 months. Flushes can be hard on the seals, the rack, and the aged lines. On a fairly new vehicle it is ok to flush but I dont recommend it on older ones. I have bought older cars that had noisy and dirty fluid. And after doing thee above All is perfectly normal. Never had to change a pump, steering gear, or pump GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
KHE Posted October 18, 2015 Report Share Posted October 18, 2015 Flushes are a revenue generating service for dealers and other shops. There is no recommendation in any of the manufacturer's manuals that specify a flush of any lubricated system. What is to be gained from changing the power steering fluid?

Lining and seal material break down an contaminate the fluid Changing the power steering fluid is something that makes the car owner feel better but really does no good or no harm. If it was truely a needed service, it would be on the maintenance schedule in the owner's manual and service manual.

rockfangd Posted October 18, 2015 Report Share Posted October 18, 2015 I am sorry but I do not believe that to be true. I have bought many GMs with noisy pumps and stiffer than normal steering and once I start changing out the fluid the noise is gone and the steering is smooth. Now keep in mind I am referring to older vehicles(pre 2k) GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
MrMagoo Posted October 18, 2015 Author Report Share Posted October 18, 2015 A flush may not be recommended as a regular thing, since it's not in the maintenance schedule in the manual, but my FSM has the instructions for the procedure, so I gather the engineers thought it would be helpful in some circumstances.

rockfangd Posted October 18, 2015 Report Share Posted October 18, 2015 You should have a power steering filter IIRC, Look in the right front corner of the bumper, forward of the RF wheelwwell., Looks like a canister. Almost like a fuel filter GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...

That procedure is for when a major component of the system is replaced - not as a regular scheduled maintenance procedure.

BodybyFisher Posted October 19, 2015 Report Share Posted October 19, 2015 Not sure if the 4.9 has a filter like the Northstar. I have a 95 service manual I will have a look. In the northstar there is a filter under the right front or near the right front area it looks like a fuel filter near the ps fluid cooler. I remember the guru saying it never needed changing but the car is 20 years old now. Ill check the manual. Personally if it bothers you i wouldnt bother with the filter there is nothing to clog and debris if any would be dusty I would just change the fluid, but I agree with KHE its probably not necessary Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
winterset Posted October 19, 2015 Report Share Posted October 19, 2015 My fluid was 18 years old when i changed it with the baster. The fluid coming out didn't have any material floating in it, but it was of a very dark brown color and smelled stale and maybe slightly burned. My goal was to go a little beyond what others might do to care for the power steering system. After a few changes over a couple of months, the color is still almost clear. I feel the seals now have a better conditioner to keep trouble away, and the fluid smells like fresh oil or grease now. Link to comment Share on other sites More sharing options...

Cadillac Jim Posted October 19, 2015 Report Share Posted October 19, 2015 My two cents is that you decide what you want to do with your own car, and for many of us Cadillac enthusiasts with older cars, sometimes we overdo it. I just changed the coolant in my 2011 two years early and had the transmission serviced 20,000 miles early, because I intend to drive the car more miles than are in the owner's manual schedule. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

James Woods Posted October 20, 2015 Report Share Posted October 20, 2015 I'd agree with members who say it doesn't hurt to change it. Also those who change fluids or a maintainence earlier then what is recommended. By not doing it or doing a service past what is recommended will hurt the vehicle. But by taking a little time now I believe that a lot of time in the life of the car will be added. Link to comment Share on other sites More sharing options...
Cadillac Jim Posted October 20, 2015 Report Share Posted October 20, 2015 Sometimes it just makes you feel better to overdo things. I knew that my coolant had another two years to go but I went seven years without changing the coolant in my Eldorado and paid the price. I had the transmission in the CTS-V serviced early because I feel that the GM-envisioned service horizon is on the order of 100,000 miles and I plan to have my car in tip-top shape at 100,000 miles and ready for another 100,000 miles. But I have no idea whether doing things early has any real, measurable effect whatsoever. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

MrMagoo Posted October 20, 2015 Author Report Share Posted October 20, 2015 I did get the fluid changed. The pump was making some noise when I got the car a few months ago, so I figured that, if anything, it would prolong the life. It is less noisy now, for sure. The service records were scanty, but I have no doubt that the car was both driven moderately and cared for moderately. I'm determined to get another 8 years out of it, and I have more peace of mind knowing exactly what's in it. Link to comment Share on other sites More sharing options...
