Question about 1991 Cadillac DeVille

I have a 1991 cadillac deville with bad power steering problems

So i have a 1991 cadillac deville that i have tried to replace the pump for power steering 2 times now. the first new pump I put in worked for about a week then the shaft came out and the belt came off. now on the second pump has started to leak directly from the pump itself within the first mile driven on the new pump. I was wondering what could be causing this problem because my mechanic cannot figure out what is causing every new pump to fail/leak.

Why is power steering fluid spewing out of the cap after replacing bad leaking power steering pump

You have Air in the Power steering System and it needs to be bleed out, And to do this if you Jack the two front wheels off the ground and Let them Hang free so there is No Load on the steering at all. please put some type of stands under the car, You will need more power steering fluid but before you add this you need to start your Car and turn the steering Wheel Slow from left to Right a few times, You will hear a wearing Notice come from the pump and you will see more fluid come out of the pump as well, that is the air trying to bleed its self out. The fluid coming out will be air rated lots of bubbles in it, Now that you have done this the Noise from the pump should start to go quite at this Point you can start to Add the New power steering fluid slow to the reservoir and keep turning the steering wheel from left to right slow (Never Fast but slow ) Have a lot of rags to clean the Mess. Hope this helps you. :)

Why is power steering fluid coming out of the cap? I just replaced the pump because it was leaking

Too much fluid is in the pump. After purging the air out of the lines stop the engine and let it settle before checking fluid level in the pump.

I have a 1991 Cadillac Sedan DeVille. Recntly, I made a tight right turn. I heard a sound and a pressure release. From this, it has been hard to steer. What is needed to fix this issue? Parts, Remedies.

I think your power steering pressure hose burst or is leaking.

Could be leaking some other place in the power steering, but you heard a pressure release it must have been the high pressure line. Obviously, there is a leak since its hard to steer. You should check your power steering lines to see where your leak is.

My 95 cadillac deville power steering just started acting up. Its not the power steering fluid cus i checked and its full. It will work then just go out then work again. Does it need a new pump or what?

I would try a new belt first. If the belt it is old it could be slick and slipping or loose which would cause problems with the steering pump..

Where is the power steering fluid in my 1991 deville

Hello: The power steering pump and fluid reservoir sit on the top of the engine toward the radiator on the passenger side, there should be a cap on top in back of the pulley that will come off, on the bottom side of the cap there is a dip stick, fill the reservoir to the line on the cap. Use power steering fluid, DO NOT USE ANYTHING ELSE.

I recently replaced the plastic adapter on my 1991 cadillac deville power steering pump. The power steering worked fine for 3 days and then started leaking again. I can not find the leak any where. I just...

Unfortunately from previous experience as a master Cadillac technician I have seen the same issue several times. There is an "o" ring between the reservoir "plastic adapter" and the pump. Very difficult to pinpoint the leak. Most likely the "o" ring is either missing or cut. Even a small nick will cause a leak.
Hope this helps.
