Hi All,

I know. . . I have one problem after another. :D


OK, I did some research here. This is current symptom that I am having. I hear screeching sound when the car is cold. It sounds like my belt is slipping. It happens every other day since last week. Only when I am turning either direction at low speed from stop. Is my power pump going south? If so, how much time do I have left? How do I know for sure it's the pump? If the pump is bad, why it's making that noise?


Here is what I have done or know so far.

1. all new v belts and they are tensioned correctly.
2. my accessory bushings are good and all alignments are true.
3. harmonic balancer is good.
4. just replaced power steering fluid with Mobil1 synthetic trans fluid using a turkey baster method, it wasn't too dirty. I am hoping to get rid of that sound.


Thank you as always.

FYI.


the original?



rebuilt one from FCP

Hi All,

It looks like it failed to upload my videos. You can go to my photo bucket account and see the videos. The sound quality has been altered after the up load but you can listen to first few seconds on both videos.

Thank you as always.

New pump

Old pump

Hi All,

Since the posting, I put about 34,000 miles on it. Currently, it has more than 281,500 miles on the odometer which is not true mileage. The pump was making a grinding noise and was getting louder. I decided to take an advantage of the warm temperature and changed the pump over the weekend. Prior to swapping the pump, I did flush the system using Mobil 1 Syn Trans fluid.


I borrowed a set of steering removal/installer tool from Autozone. It wasn't in a great condition but I was able to complete the job. My original plan was to use my 2 arms jaw puller and hammer the pulley back in the stud. I am glad that I didn't do that.


I put 2 layers of large plastic bags to catch the fluid. The low pressure hose came off easily after removing the high pressure line first.

See my video on the next thread, it may take a day or so to upload. Thank you as always.

Hi All,

It looks like I am missing a fastener here. I tried to use a bolt and a wing nut that I have in my tool box but it was too small and couldn't hold with enough strength.

By any chance, does anyone know the exact size and length? I tired to look on the web but it looks like they no longer have diagram parts listing. Thank you as always.

this pdf has it all

Hi CB,

"this pdf has it all"

No kidding. . . It's on page 830. I will match the part #17 & #20. Thank you as always.

It sure sounds like a belt slipping.

Hydraulic pumps usually make a growling or groaning noise when they go bad (bearings), or they just don't put out as much pressure (wear or pressure relief springs). They run in oil so the pumps last a long time.

Any chance your new belt is too narrow? Do you still have the old belt ? If so you could sub it in and see if the noise changes.

Hi Greg,


I forgot to mention. The water pump belts were too loose, especially the one that's closer to the engine block. It's running good without any noise for now.

Thank you!

Hi Greg,


OK, I will take that over a bad pump.

Yes, I still have the old belts, they have acceptable cracks but I decided to change them anyway. I compared them side by side, all belts are correct width and length. But then again, I told that you my belt tensions were correct. :-) I am not too sure about the length since I compared them visually.

I am trying to figure out which belt is loose. Is there any trick to isolate the problem? Spray water maybe?

Thank you as always.

Mine(88) 195k was making some noise awhile back. I sprayed the backside of the pulley to lube that bearing and that took care of it. Consider installing a Magnefine in-line PS filter as well.

Hi Joekidd,

I will lube it tonight. Thank you. Happy Friday.

I lubed the pulley. Thank you.
