What would be an acceptable replacement o-ring for the power steering pressure switch on a 1989 ford f-150 xlt lariat 4x4 5.0 automatic? All the auto parts stores and dealerships i've checked with sell the complete switch, but not just the o-ring by itself.

Code po551 after 2.7 to 3.2 conversion


I have no experience doing this conversion myself but that code should have nothing to do with the engine itself. The code indicates that you're having a problem with the power steering pressure switch (psps). I suspect that the connector to it got left of or damaged during the engine swap. The psps senses when the steering system is loaded, such as tight parking turns and then tells the computer to increase idle speed so that the engine does not stall. If the wire to the switch is left off or damaged, the code will set. You'll need to inspect the high pressure line coming from the power steering pump. Somewhere between the pump and the steering rack you will see a small oil pressure switch with a couple of wires going to it...or at least it should, the connector might be hanging somewhere near it.

How to install a power steering pump for a 1997 chrysler seabring conv


Chrysler Cirrus/Stratus/Sebring/Avenger/Breeze 1995-1998
Power Steering Pump - REMOVAL & INSTALLATION

Cirrus, Stratus, Sebring Convertible and Breeze
(see Figures 1, 2, 3 and 4)
  1. Disconnect the negative battery cable from the left strut tower. The ground cable is equipped with an insulator grommet, which should be placed on the stud to prevent the negative battery cable from accidentally grounding.
  2. Siphon as much power steering fluid out of the reservoir as possible.
  3. Raise and safely support the vehicle.
  4. Remove the right front tire and wheel assembly.
  5. Remove the splash shield from the right front wheel well.

Fig. 2: Power steering pressure hose attachment to the pump-without Variable-Assist steering
  1. Disconnect the power steering pressure hose from the pump.
  2. Remove the hose connection on the power steering pump.
e7733b2.jpg

Fig. 3: Typical power steering pump front bracket attachment
  1. Remove the power steering adjusting bolt.
  2. Remove the power steering pump rear attaching bolt.
  3. If so equipped, remove the Anti-lock Brake System (ABS) hydraulic control unit heat shield.
  4. Remove the wheel speed sensor retainer bracket from the right inner fender.
  5. Remove the wheel speed sensor sealing grommet from the right inner fender.
  6. Disconnect the speed sensor wiring.
  7. Push the wiring through the hole in the inner fender.
If not equipped with anti-lock brakes, the hole will just have a sealing plug.
  1. Remove the bolt attaching the power steering front bracket to the mounting bracket. Access to the bolt is gained through the hole for the speed sensor wiring.
  2. Remove the power steering pump drive belt.
  3. Remove the power steering pump and the front bracket as an assembly.
To install:
  1. Install the power steering pump and bracket.
  2. Reinstall the bolt at the adjusting slot, but do not tighten.
  3. Reinstall the bolt mounting the power steering pump to the rear mounting bracket, but do not tighten.
  4. Reinstall the power steering pump top bolt, but do not tighten.
  5. Reconnect the power steering hoses.

Fig. 4: Install a new O-ring gasket on the hose fitting
Use a new O-ring when reinstalling the power steering pressure hose.
  1. Reinstall the drive belt.
  2. Adjust the drive belt and tighten the power steering pump bolts to 40 ft. lbs. (54 Nm).
  3. Reinstall the splash shield.
  4. Reinstall the tire and wheel assembly.
  5. Lower the vehicle.
  6. Reconnect the negative battery cable.
  7. Refill the reservoir and bleed the power steering system.


Sebring Coupe and Avenger
  1. Disconnect the negative battery cable.
  2. Remove (drain, suction pump, etc.) as much power steering fluid as possible.
  3. Disconnect the return fluid line. Remove the reservoir cap and allow the return line to drain the fluid from the reservoir. If the fluid is contaminated, disconnect the ignition high tension cable and crank the engine several times to drain the fluid from the gearbox.
Cover any components located underneath the power steering pump with a shop towel to protect them from damage due to power steering fluid spillage. For example, the A/C compressor or alternator, depending on vehicle and engine, is below the power steering pump, so cover the A/C compressor or alternator with a shop towel before removing any hoses.
  1. Loosen (but do not remove) the power steering pump mounting bolts and remove the drive belt.
  2. Remove the pressure switch connector from the side of the pump.
  3. Disconnect the pressure line.
  4. Unbolt and remove the pump from the mounting bracket.
To install:
  1. Clean all parts well. Inspect the pump pulley for cracks. Check the hoses carefully for cracks or signs of weakness.
  2. Install the pump, wrap the belt around the pulley and lightly tighten the mounting bolts.
  3. Replace the O-rings and connect the pressure line. Connect the pressure line so the notch in the fitting aligns and contacts the pump's guide bracket. Tighten the fitting to 13 ft. lbs. (18 Nm).
  4. Connect the return line and secure with the clamp.
  5. Fasten the pressure switch connector.
  6. Adjust the power steering belt for proper tension and tighten the adjusting bolts.
Use only MOPAR ATF PLUS automatic transmission fluid type 7176, ATF+3 automatic transmission fluid, or equivalent, in the power steering system of Sebring coupe and Avenger models.
  1. Refill the reservoir and bleed the power steering system.

Hope this help to solve it (remember comment and rated this). TY for using Fixya.

Leaking at pressure side of connection


What are we talking about? Preasure side of AC compressor pump? Power steering pump?
If AC, then possibly from a leaking AC-high preasure switch on the back of the compressor. The leak could be simply the O-ring. You simply unscrew it and install the replacement making sure the O-ring is good and in place. The switch can leak also. This part is hard to find accept at the dealer. It has a 4-wire connector on it.

O ring is leaking from power steering pressure hose


I had the same problem. You can not replace that o ring. You have to replace the complete hose ***. They redesigned the hose to fix that common problem. To bad the customer has to pay to replace a poorly designed part.
