Well, the 2003 Dakota service manual specifically states to use ATF+4 in the power steering system, and it doesn't differentiate between engines even though the 3.9 and 5.9 get the Saginaw pump. The 4.7 uses an entirely different designed pump.
I did talk to the Dodge dealer's service manager today, and he said they have never replaced a power steering pump for a 4.7. In fact, he said the only problems they've had were on Caravans, when during a period they had pump pulleys come loose.
I asked him about the dark color of the ATF in my Dakota, and said he wasn't aware of any problems. But I'll be keeping an eye on it just the same.
#2349 of 4362 P/S Cooler from JimT.
Aug 06, 2003 (5:20 pm)
(bpebbles) Yes, my '01 has the cooler. I have not "changed",flushed system again as yet, but I intend to do the same--- change it 'till it is clear and "clean" smell. The head mechanic at my FD shop is an Amsoil dealer and I am going to check their product line. His price on gallon of synthetic differential fluid was under $30.00, so price should not be bad. I will continue using Napa to flush system.
I am a little concerned about my vehicles reliability with pinion seal replacement and probable poor dealer repair causing axle whine; A/C compressor failure with $900.00 repair tag including new receiver/dryer and belt; and possible P/S pump problem.
Anyone flushing brake fluid? I thought that may be good next maintenance item.
#2350 of 4362 Brake fluid flush
Aug 06, 2003 (6:21 pm)
(jimt) I plan on replacing my brake fluid before the snow flys this year. (I figure I have another month or so I am currently using my vacuum brake bleeder to suck the PowerSteering fluid out every couple of days. Takes about 5 minutes to replace all fluid in resivour.
I realize this does not remove ALL of the PS fluid... but it is MUCH easier and there is less chance of getting dirt into the system like when a hose is pulled off. (which would be immenent failure for the pump or seals.)
Like you said... a GALLON of NAPA PS fluid is about $10 so that will go along way twards my partial fluid changes.
For those of you that are wondering why I am replacing my various hydrolic fluids.... they are hydroscopic. That is, over time, they 'attract' moisture and turn brown. This water in the system will cause corrosion. (Did you ever wonder why ALL brake fluid is supposed to be from a "TIGHTLY SEALED CONTAINER"... it sucks the water right out of the air into itself.)
I have replaced enough master cylinders and calipers to know that complete fluid replacment every couple of years is less costly and safer than having the brakes fail when I need them most.
Replacing the brake fluid is not difficult... pulling all 4 wheels is what takes the time.

bpeebles - I've always been suprised that more manufacurers don't recommend flushing the brake fluid periodically. I know that Subaru recommends doing it every 60K miles. Flushing is especially important if you have ABS. It is cheaper than replacing an ABS unit.
#2352 of 4362 Trouble code
Aug 07, 2003 (3:37 pm)
Well my I got a P0442 Evaporative leak today message today on my 01, 4.7 auto, 4x4. I have a list of 5 other things to do so I have scheduled to have this taken care of. Isnt this the gas cap error? It is on right and its been over 100 miles since last fill up.
#2353 of 4362 Trouble code P0442

(henne) As I have said before, I had an emmissions leak DTC due to a HOSE popping off under the vehicle.
Directly under the drivers door, on the other side of the framerail, there is a plastic "canister" with several hoses plugged into it. One of those hoses was pulled off. (there was no hoseclamp from the factory.)
You can lookup the code listing here; http://www.obdii.com/codes.html

#2354 of 4362 PowerSteering fluid type
Aug 08, 2003 (9:54 am)
I have researched the questions about what PS fluid to use in the Dakota. It turns out that everyone is correct 8-)
Originally, actual "PowerSteering fluid" used to be the only recommended fluid... but as of August 2001 the recommended fluid changed to ATF+4. I have pasted the details of Technical Service Bulliten 19-007-01 below.
TSB# : 19-007-01
DATE: AUG 01
DESCRIPTION: Power Steering - New Fluid Type
The factory fill power steering was or will be changed for 2001 and 2002 vehicles. The new fluid is ATF+4 (M59602) and it provides superior performance in both low and high end temperatures. ATF+4 P/N 05013457AA(quart) and 05013458AA(gallon)
ATF+4 is compatible with other Chrysler approved fluids but to avoid confusion should not be mixed for "Topping Off".ATF+4 should become the replacement fluid. If a steering system is being serviced for fluid loss, pump replacement, hose, gear or rack replacement, the complete system should be drained and refilled with ATF+4.

#2355 of 4362 Trouble code least of my worries
Aug 10, 2003 (2:03 pm)
Well it was as bpeebles said. I had 2 vacuum hoses that were split. They said my milage would get better also as it has gone from 16mpg avg to 10mpg avg.
Now the fun part. My transfer case is leaking fluid and I did not know it when I took it in. I looked under the truck to see how everything looked and saw oil everywhere. The dealer didnt see it and it has been there awhile, so I am not sure how long is been leaking so now back to the shop it goes.

Havent checked postings in a while, but about 2 Weeks ago I changed the PSF with RedLine Power steering fluid. The Redline Rep. said that C+ ATF was the correct fluid to use but since I already had the PSF I went with it. If it worked a year ago it will work now. (Bpeebles) I also noticed that the new fluid turned brown almost immediatly and I was pretty sure I got most out. Maybe I'll try to flush the system several times also. I disconnected one of the lines at the bottom of the cooler and then forced the wheels left and right until the fluid stopped draining out. By the way, what is the best way to flush the brake system.
#2357 of 4362 Dakota Power Steering Fluid
Aug 11, 2003 (3:00 pm)
I checked a couple of brand new Dakotas over the weekend that were on the dealer's lot and the fluid was just as dark as mine. So I have been trying to figure out why ATF+4 would change color so rapidly when used in the power steering.
The significant difference between a power steering system and an automatic transmission is the amount of absolute pressure of the fluid environment. Since ATF+ series use a non-permanent dye, I wonder if the effects of fluid compression (pressure) is causing premature dye oxidation.
