Hi,

I have 2007 Dodge Caravan and want to replace power Steering Reservoir's Fluid, the owner manual says that it should be (MOPAR ATF+4 Automatic Transmission Fluid), the available type is (ATF Type III).
Can I use it ???

Please Help ASAP

 

u should always use what it says to use!
what do you mean the available type is ----? ur trans uses atf +4 and that fluid is available everywhere including foreign countries

 

Could cause the screen in the reservoir to be restricted and then you will have lots of noise and possible damage. Don't use it. Use what the Owner Manual says.

Why do you want to replace the fluid? What mileage?

ATF+4 fluid is available everywhere. Auto parts stores have it. Even WalMart carries it. It's a better fluid than ATF+3. If you're going to change it, use the newer fluid.

 

Dears,
I want to replace it because When i stop my 2007 dodge caravan and turn the steering left or right vibration will heard and feel.
i noted that the vibration increased when the engine temperature increased and decreased when i raised the RPM.

 

Sounds like the screen in the power steering reservoir is dirty (flow of fluid is up through it) and there's not enough fluid being returned / air is getting in. That can happen at 60,000 miles (very, very approximate) or if the wrong fluid has been added and is clogging the screen. The ideal solution is to replace the reservoir (the very fine mesh screen is not a replaceable type - I have a reservoir cut apart and it's part of my collection to be buried with me when I go. lol)

Some just add more fluid to their reservoir, leaving only a little air at the very top. That works, but probably best to replace the reservoir. Sometimes making sure the cap is tight can help. There's an "O" ring seal on the stem portion of the cap (air tightness, no venting, is important for proper operation apparently).

Tools Needed: A turkey baster (to remove the fluid), fluid container, wrenches, vice grips, screwdriver and a little help from your friends on here as to the hidden bolt involved. lol
The small line at the top is the return line and the larger line at the bottom is the supply. The reservoir has the bolts that are obvious on the top plus a hidden bolt underneath which accomodates a vertical slot in the very bottom portion of the reservoir. This hidden bolt just needs to be loosened, not removed, so the reservoir can slide out (clamping effect). Need any more info?

PS: The reservoir might be covered by warranty.

 

Dear TJeepman,
Thanks very much for your benefit information, I really very interested by your replay.
My question if can I clean the screen of the power reservoir ? May that help ?

 

it's not going to hurt so why not try removing the reservoir, flushing it clean, install with new fluid. at worst it won't help but it sure wont hurt

 

The flow is up through the reservoir. The larger supply line (bottom) and the smaller return line (top) aren't far apart. The fine mesh screen is between them. Cleaning would have to by flushing downward to remove the build up on the underside. Here's what you are dealing with: http://forum.chryslerminivan.net/sho...26&postcount=1
Some have tried cleaning them (running a chemical product back through the screen) with some success. Could try paint thinner, mineral spirits, gasoline or something like that and then blow with pressurized air. On first thought, I might try gasoline, then pressurized water and then pressurized air (both directions). Best bet is a new reservoir. Not that expensive but recently went up in price, I hear.

 

NEVER use gas for cleaning stuff. mineral spirits are fine.
