Agreed. Thats how I screwed up my cooling system. Thanks.

 

From the fsm

DESCRIPTION - POWER STEERING FLUID
Mopart ATF +4, type 9602, Automatic Transmis-
sion Fluid is required in the power steering system.
Substitute fluids can induce power steering system
failure.
Mopart ATF +4, type 9602, Automatic Transmis-
sion Fluid when new is red in color. The ATF is dyed
red so it can be identified from other fluids used in
the vehicle such as engine oil or antifreeze. The red
color is not permanent and is not an indicator of fluid
condition. As the vehicle is driven, the ATF will begin
to look darker in color and may eventually become
brown. This is normal. ATF+4 also has a unique
odor that may change with age. Consequently, odor
and color cannot be used to indicate the fluid condi-
tion or the need for a fluid change

 

Sags were basically all the same and they just changed the reservoir. And in most cases all that changed there was the shape and angle of the return line barb.....and maybe overall clocking of the reservoir.

You can still get just the pump a-la-carte. My local O'Reilly even stocks it. And RA lists it as the same part # as O'Reilly: 731-0125

Calling up the buyer's guide, you can see a Sag is a Sag is a Sag. This was for a '00 Ram 5.9 Magnum. I then called up an '08 Sierra with LMM Duramax because I know they still used Sags. Yep, same pump.


So, let's see.....in '80-84 was AMC recommending ATF+4? Somehow I doubt it.

Cadillac, Chevy, GMC, Hummer and Pontiac? No way they're gonna reco a Chrysler fluid. That would have been DexIII or later DexVI (reverse compatible)

Ford? Well that's Mercon, er scratch that we now call it MercV.

 

Lol I never said anything about the pump not being the same. What I pointed out is that Mopar calls for atf +4. Nothing more. Use what you feel is right. My Mistress has atf +4 for ps fluid, my 01 rango has ps fluid. Take your pick they both work just fine.

 

You just quoted the FSM. I don't see anything wrong with that??

 

Not a thing, for the most part the fsm rules. It's been awhile, I gotta read posts better lolol.

 

Just replaced a pump yesterday on a 2000. Used a reman (with reservoir) from O'Reilly.

Filled it with M1 syn ATF because I have a ton of it from when AZ was blowing it out at $3/qt earlier this year.

Bled it running with no weight on front wheels, slowly cranking side to side, as I always have. It bled fine, is quiet and working great.

As an aside, the old pump was leaking profusely and this is the first time I've ever heard a p/s pump make a terrible, constant bearing squeal, but it was.However if you spun by hand it felt fine and there was no play in the pulley shaft. Kinda weird.

 

It isn't bearings that are making the noise. It's pump cavitation. (trying to pump air.) And yep, it sounds HORRID.

 

I guess so ....but it had seemingly good assist. If cavitating I'd expect a noticeable drop in assist, but maybe not

 

Depends on how hard/fast you are trying to turn. For the most part, you won't notice.... but, try and spin the wheel quickly, and you should.
