87 Seville 4.1 power steering locking up after doing valvecover gaskets.only disconnected return line on power steering pump.

Involves disconnecting the outer tie rod ends. Steering linkage from steering wheel. Disconnecting the power steering pump lines and unbolting the rack and pinion from the body.
Look at the new one for bolt locations. Make sure the new one comes with new tie rods or you might be back under there again too soon.

Hi Pedro
Are you sure its oil? not antifreeze? Radiator Leak? that means you have a cooling system problem. f it looks like oil and infact check your valvecover gasket covers maybe over heating toasted the gaskets check the bolts snug them down a bit see if they move easliy maybe thats your oil leak. Also check your power stearing hoses maybe you didnt notice little leak of power steering hose leaing or even clamps on return hose maybe need snugging. Also you may have arped a head and leaking oil between head and engine block . Shampoo engine by Garage dont do it yourself unless you know what your doing you may just end up spending alot of money if you get everything wet under the hood. Then look for the leak and look closly at the color of the fluid use a clean paper towel and look at the color on the white towel. Find out why it over heated Fix that problem and goon to this leak maybe you have a leak spraying up to your head presure test your cooling system.

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. 1: Power steering pressure hose attachment to the pump-with Variable-Assist steering



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.
   

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.

9. Remove the power steering pump pulley from the power steering pump.
10. Remove the power steering pump reservoir from the power steering pump.
Installation Procedure
1. Install the power steering pump reservoir to the power steering pump.
2. Install the power steering pump pulley to the power steering pump.
3. Position the power steering pump to the engine.
Notice: Refer to Fastener Notice in Service Precautions.
4. Install the power steering pump mounting bolts.
Tighten the bolts to 25 Nm (18 ft. lbs.).
5. Connect the power steering pressure hose to the power steering pump.
6. Connect the power steering return hose to the power steering pump.
7. Install the harness connector (1) to the power steering pump (4).
8. Install the accessory drive belt.
9. Fill the power steering system with fluid.
10. Bleed the power steering system.
11. Operate the power steering system and inspect for power steering system leaks.

When power steering hose replacement is required, follow these steps:

1. With the engine stopped, remove the return hose at the power steering gear, and allow the fluid to drain from this hose into a drain pan. On some cars, the vehicle must be lifted on a hoist to replace the power steering hoses.
2. Loosen and remove all hose fittings from the pump and steering gear.
3. Remove all hose-to-chassis clips.
4. Remove the hoses from the chassis, and cap the pump and steering fittings.
5. If O-rings are used on the hose ends, install new O-rings. TRW steering gear cylinder lines have gaskets that are serviced as a unit. The old gasket must be pried out of the fittings in the housing before the new lines and gaskets are installed. Lubricate O-rings with power steering fluid.
6. Reverse steps 1 through 4 to install the power steering hoses. Tighten all fittings to the manufacturer's specified torque. Be sure all hose-to-chassis clips are in place. Do not position hoses where they rub on other components.
7. Fill the pump reservoir to the full mark with the manufacturer's recommended fluid. Bleed air from the power steering system. Check the fluid level in the reservoir and add fluid as required.

you need to have a pulley puller to get the pulley off if you don't have one most auto zone part stores have a loan a tool program and they can help you with that on most powersteering pumps the high pressure line will be a fitting or bolt on and the return line is usually just a squeeze clamp hope this helps good luck

1. Disconnect power steering pump return line and allow power steering pump fluid to drain into a suitable container.
2. Disconnect power steering pump pressure hose from pump fitting.
3. Disconnect drive belt from power steering pump pulley, remove pulley, then remove pump.
4. Reverse procedure to install. Torque pump to mounting bracket bolts to 30-45 ft lb.
