How much power steering fluid is needed to fill a completely dry power steering system in a 1992 corvette hatchback base model?

spray down pump and hoses with degreaser and wash off. After its dry, use recomended fluid to fill. Start engine and turn steering wheel all the way left, and all the way right a couple of times. This will blead the air from the system. Now shut off and check fluid. Make sure it is full. Now drive the car down the road and make turns, and drive it back and check fluid level. If its still foamy and not leaking fluid, your pump ma be bad.

replacing a line wouldnt be to hard, neither would replacing the whole pump, which is probably what you will have to do. If you checked it and it was dry then there has, more than likely been damage done to the pump. The biggest problem with your situation isn't really difficulty of the job but more the cost of replacement parts. I can't say for sure on your vehicle but pumps can get pretty pricey for some cars. Good luck on your fix.

1992 Pontiac TransPort Power Steering Pump REMOVAL AND INSTALLATION

1. Disconnect the negative battery cable.
2. Disconnect and cap the power steering pump hoses.
3. Remove the accessory drive belt.
4. Remove the power steering pump pulley using a suitable puller tool.
5. Remove the pump mounting bolts and remove the pump from the vehicle.

See Figures 1, 2 and 3

Fig. Fig. 1: On some vehicles, you must use a puller to remove the power steering pump pulley

1. Installation is the reverse of the removal procedure. Tighten the pump mounting bolts to 18 ft. lbs. (25 Nm).
2. Bleed the power steering system to remove trapped air. Air in the system could cause noise and or damage to the pump.

BLEEDING

This procedure requires the help of an assistant.

1. With the engine OFF, the wheels off the ground and turned all the way to the left, fill the fluid reservoir to the FULL COLD mark on the fluid level indicator.
2. With an assistant checking the fluid level and condition, bleed the system by turning the wheels from side to side without hitting the stops. You should repeat this at least 20 times, making sure to keep the fluid level at the FULL COLD mark.

Fluid with air in it has a light tan appearance. This air must be eliminated from the fluid before normal steering action can be obtained.
See Figure 4

Fig. Fig. 4: Power steering bleeding procedure

1. Start the engine, and while it is idling, recheck the fluid level and add as necessary to reach the FULL COLD mark.
2. Return the wheels to the center position. Lower the front wheels to the ground and continue running the engine for 2 or 3 minutes.
3. Road test the vehicle to make sure the steering functions properly and is free of noises.

See Figure 5

The power steering fluid goes in the power steering pump which is on the drives side of the motor below the alternator.It is black and has a twist off cap.The cap is a dip stick type.It has levels which will have a hot and cold level.If the engine is cold fill to the cold level.If it is hot then fill to hot level.Hope this helps.

POWER STEERING PUMP IS USUALLY ON THE PASSENGER SIDE OF THE CAR . YOU WILL SEE FAN BELTS AND PULLEYS CLOSE TO THE FIR WALL YOU SHOULD SEE A CAP THAT SAYS POWER STEERING
THE OIL TUBE IS BETWEEN THE ENGINE AND THE FIRE WALL YOU SHOULD SEE A YELLOW TEE HANDLE OR A RING FOR YOUR FINGER THIS IS FOR THE TRANSMISSION. YOU MUST ALWAYS CHECK THE TRANS WHEN HOT AND RUNNING AND NEVER OVER FILL YOU WILL SEE SLASH MARKS ON THE STICK NEVER FILL ABOVE THE SLASH MARKS

You can use any fluid marked as power steering fluid. (not transmission fluid) Use dot3 brake fluid in brake systems. Don't use synthetics in brake systems unless system has been completely disassembled and cleaned.
For better service life, remove brake fluid from reservoir with a turkey baster once a year and refill with new fluid (no bleeding required) You can also drain power steering and re-fill every two years by removing return line to pump, allowing it to drain, then re-connecting and re-filling. Nothing lasts forever, but this helps it last a lot longer.

Yes There Is ONLY ONE PLACE for Power Steering Fluid.

ZF Gemmer Steering

The ZF Gemmer steering is permanently filled with oil. There is no drain plug.

ZF Rack and Pinion Steering Without Power Assist

The ZF rack and pinion steering is lubricated for its service life and therefore does not require servicing.
In case of repair, steering components on E21 vehicles are to be lubricated with a sodium-based grease, with a temperature range of -30°C to +75°C .
Calypsol D 4024 BMW Part No.32 11 1 116 929

Ball and Nut or Rack and Pinion Power Steering

Only reputable brand Automatic Transmission Fluid (ATF) of Dexron® III formulation may be used for the power steering and power steering pump.
In case of brief hydraulic noise after starting at low outside temperatures, we recommend replacing the red ATF with green CHF or LHM oil (see below).

ZF Ball and Nut Power Steering with H31 System

The approved oils for BMW models with power steering and the H31 brake booster system are identical with those oils approved for power steering without the H31 system except for the following:

E32 models with self-leveling rear suspension and mutual oil supply tank in the engine compartment.
Countries with very low outside temperatures (e.g. Canada) had their power steering systems filled at the factory with Pentosin CHF 7.1 since 9/87 through 9/91. This is also to be used on vehicles built before 9/87.

Since 9/91, vehicles now use Pentosin CHF 11S instead of CHF 7.1.

Pentosin CHF 7.1 BMW Part No.81 22 1 468 879
Pentosin CHF 11S BMW Part No.82 11 1 468 041

These cars are marked with a pertinent label located close to the oil tank.

LHM oils (green color) of the following manufacturers may also be used instead of Pentosin (CHF 7.1):
Shell LHM
Castrol LHM
Exxon LHM

The mixing of CHF, LHM oils and ATF is not permitted.

Pentosin CHF 4548 was used on vehicles built before 9/87 but is no longer available. However, mixing of Pentosin CHF 7.1 with residual quantities of Pentosin CHF 4548 are permiffed in these earlier vehicles. Mixing of these two oils is not permitted for E32/E38 vehicles.

The hydraulic system for power steering and power-assisted brakes must be drained as completely as possible when changing from one type of oil to the other.
All oil supply reservoirs are marked with the type of oil being used - ATF or CHF.

The power steering pump on a 1980 corvette is located directly under the alternator. I have found it easiest to reach between the alternator belt and unscrew the cap, then use a long stemmed funnel to fill it. If you shine a flashlight down into the spout, you'l avopid overfilling.

Power steering noise When the fluid is low and you add some ... it still needs more after you run it for awhile. The reason for that is that the pump pumps the fluid through the lines and gets out the air in them. Keep filling and checking after you start the car and turn the wheel from side to side all the way.

• The bigger question is why do you need to add fluid? After you locate and fix that leak, you can address the whine. If it is a Ford, it may be somewhat normal. Like Drazi said, "It may be air trapped in the line." Or the pump may be damaged from running it dry, or there is blge in the line, starving the pump. Let's assume you have kept up on the maintenance and have flushed the fluid when it was dirty. Let's also assume that the pump is not damaged and you have found and fixed any leaks. Try this: pull the fluid out of the reservior and add one bottle of Lucas brand power steering additive, and top with power steering fluid. I have found this stuff pretty good at resolving many power steering problems. I'm not a big supporter of "Snake Oil", but have had good luck with it.

• well" if it's a ford it's because they use plastic parts in there casing's. most other car company's do the same. if that's not the case, then your pump is reciving too much stress from turning. try lubing up the chasis and changing the fluid completly. it wouldnt hurt to check your line's ether. sometime's blockage can cause too much stress on the pump too.

• First thing is why are you adding

fluid. If it has a leak then i would address that problem first. A pump will not bleed out if it is leaking. If every thing seems to be okay and your pump still whines. Then replace the pump. Note my advice is replace the pump with a new one from the dealer. These so called rebuilt pumps that you buy from places like autozone o'rielys ect.. Are cheaply rebuilt. Especialy if it's a ford. They don't bleed out right improper pump pressures. A good pump will bleed out almost imediatly.With the turn of the wheel a few times. If it doesn't then your pump will more than likely never completly bleed out. Buy a pump from the dealer it cost more but if your like me and don't like the noise then it's worth it.

• You probably have air trapped in the system. Bleed the air out by revving the engine to about 1500-2000 rpms and turning the steering wheel almost all the way from one side to the other a few times. This should bleed out the air and take care of your problem.

• If the noise is similar to that of a dry bearing, then the problem probably revolves around the power-steering pump itself. If the noise you hear has a "click, click, click" to it when making turns in your vehicle, then the problem is more-than-likely your CV joints. If the noise is screeching, check your belt for wear-and-tear and proper tension (see owner's manual).

I just wanted to add another two cents about the topic of bleeding or burping the power-steering system:
1. Know what type of power-steering fluid is needed for your car. Some power-steering pumps can use automatic transmission fluid, others have specific power-steering fluid for each car i.e. Honda requires and suggests that you use Honda's brand power-steering fluid (see owner's manual). Make sure you know, or the warranty from the dealership or from the parts store may be voided.
2. Before attaching the power-steering belt, fill pump with required amount and type of fluid, (see owner's manual) and turn the pulley wheel by hand a few times. This helps cut down on dry turns before they can happen. If more power-steering fluid is needed fill accordingly.
3. Attach the power-steering belt with proper amount of tension (see owner's manual).
4. Turn vehicle on and proceed to turn the steering-wheel all-the-way right and left 3-4 times.
5. Turn the vehicle off and examine that the belt tension is acceptable, and again check the level of fluid and fill accordingly.
6. Always, always check your owner's manual before performing any maintenance on your vehicle. An educated car owner is a safe car owner!





Another possibility How long has the pump run without fluid for? There could be damage inside to the cam an rotor (assuming it's is a vane type pump), to the plates or it could be cavitating due to the ingress of air - possibly why the fluid leaked out in the first place.
