I JUST CHANGED MY POWER STEERING PUMP. I HAVE GOT ALL AIR OUT BUT I NOW HAVE A PROBLEM. WHEN IT GETS COLD (20 OR LESS), I START IT THE PUMP WHINES AND IT PUSHES THE FLUID OUT OF THE RESERVOIR CAP. I HAVE TO THINK IT WOULD BE SOMETHING STICKING IN THE STEERING BOX. THE TEMP IS THE BIG QUESTION IT DOES FINE WHEN ITS ABOVE 20 OR SO. PLEASE HELP ME WITH THIS ISSUE.

THANKS

Did it do this before you replaced the pump? What kind of fluid did you use in the pump? Could be a restriction in the low side hose keeping it from returning, or could be the valving in the pump is sticking at low temps

It did not do this before I changed the pump. I used prestone power steering fluid. At this point are there any test methods I can do at low temps or should I start by replacing the pump again? This is my nightmare.....

If you just got hepump, I would have them warranty it and try another. It all started with the pump

So this morning I went out started the jeep and the pump whines and when you turn the steering wheel louder whining. Here was my test. I got the hair dryer and put it on the pump for 5 to 10 mins. After that I started and no whining even when I turned the wheel. So this tells us that something in the pump is sticking when it gets cold. How could a new pump do this? I know when I first installed the pump and ran it I didnt get all of the air out so I guess that could have damaged it.

Thanks for your help. I will be using this site in the future.

Thanks Denver Cregger

Could just be an O'ring that is a little too tight and when it gets warm it will work.People build them, there will be problems here and there
