I am trying to replace a leaking power steering pressure hose on 89 Maxima SE. I already have the replacement hose, but I cannot get to the nut both that secures this hose to the pump. I have tried from under the car with an 24mm open/closed end wrench and also tried getting a 24mm socket and rachet ... but there is no room for either tool to remove this nut. Please advise on what tool to use and how to access this nut.

When I did it, I think I had to pull the elbow off. If you look closely, there's a short piece of tubing or something that connects the hose to the pump itself. you should be able to reach one of the two bolts there in order to disconnect the hose from the pump. then just pull it off with the little elbow intact and install it on the new hose while you have it out of the car.
It's been about 4 years since I had to do that so I'm a little fuzzy on the details. good luck.

then you're going to have to pull the pump itself off the car. there are three bolts going through the front of the pump (turn the wheel on the front and stick a socket through them)
and one bolt on the back of the pump.
remove it from the car and bring the hose off with it.
and one bolt on the back of the pump.

According to the Haynes Repair Manual for 89-92 Maxima, you need to remove both the high pressure hose and return hose before you remove the mounted bolts that hold the pump in place. Its seems like a big job to remove the pump to replace the high pressure hose. My problem is that I can get the wrench on the bolt, but I do not have enough space to get enough torque to to break loose the bolt, and a breaker bar with a socket will not fit in that tight space. I read somewhere else in this forum that another Nissan Sentra owner had to use air ratcheted to get his out. I might have to do the same.Matt93SE said:
the return hose is easy to remove, just a hose clamp.
the pressure hose is disconnected from the other end, so if you remove the pump then you can just pull it down with the hose.
inconvenient, yes. but that may be your only choice. I've done this job half a dozen times and never had a problem popping the bolt loose on that end of the hose. the hard one is the top fitting that twists in its rubber mount when you try to remove the bolt. finally I had to clamp it in some huge channel locks and remove it with an impact wrench.

Is the bolt on the back of the pump the same size as the ones on the front. I took out the bolts from the front, and loosened one bolt on the back of the pump. This bolt head size is a smaller that the bolt head size on the front of the pump. Anyway, I could not even move the pump. Did I loosen the wrong bolt on the back? Is the bolt size on the back the same size as the ones on ther front?Matt93SE said:
I was able to replace the high pressure hose without removing the pump. Yeahhhhhhh! The pressure hose is connected to a 4 inch steel pipe that is connected to the pump (this is where the pressure valve is located). I was able to remove the steel pipe with a 24mm wrench and remove the hose attached to it. Thanks for your helpMatt93SE said:
Yes you are right! I had to remove all the gunk that was created by the leaking hose so I could see the pump clearly. The pressure hose is connected to the pump by a removable 4 inch steel pipe connector, and the hose from the reservoir is connected to the pump via a removable elbow connector.Matt93SE said:Ummm, that piece of pipe is what I was referring to in my very first reply.....
