guys l need your opinion on what you think could be wrong with my steering pump. on cold starts it makes this squeaking noise but stops the squeaks when it warms up. here is a video of it. thank you

Maybe it's my speakers but I'm not really hearing a squeak. You can try dripping water on the serpentine belt to see if it goes away. It's a bit messy as it does sling it everywhere but if your squeak stops than you know it's the belt. If the belt still looks good you can mark it with a crayon and reverse it's direction. If not, then you just replace the belt.

 

I could not hear a squealing either. I wouldn't worry about that. However, I do hear a rythematic sound that makes me think the timing is off a little. Would anyone else agree?

 

RSPI, what rythematic noise is that? my timing is very much on time.will a wrong timing cause noise? l hear a sound like a bearing noise near the timing belt cover when its warm and l learnt that its the water pump bearing. when the radiator fan turns on that noise stops but comes back when the fan shuts off after cooling.l will take another video in the morning and post it up tomorrow.

 

Yeah, I hear a tick in your video, but not a squeal.

 

How hard is it to replace a power steering pump?

 

some how hard without the right tools and a first timer. it took me less than 10minutes to replace mine when it was leaking.

 

RSPI, tell me if you hear any strange sound in this video.it sounds normal to me.this is when it was warmed up.thanks

Really ?? Replaced the pump in 10 min ,,, really ??
I'm sorry but IMHO it's going to take a lot longer than that. It's not that hard but it's likely one to two hours depending on your tools. The hard part for me was messing with the tensioner that had a dedicated tool to take the tension off the belt. I finally bought a new tensioner that uses a regular 1/2" drive breaker bar in a 1/2" hole on the arm.

Have you found the source of the noise yet ??

 

l have not found the source of the noise but l am sure it is coming from the roller that holds the belt on the pump, l dont know the name.l will take it off when l get the chance.And yes it took me almost 10minutes to remove my pump because l knew where all the bolts where located,my mistake, not to change but to remove the pump,and roughly 20minutes to install the new pump. had the right tools ready and it wasnt my first time removing the pump.l had removed it to replace my alternator and on my friends s70,so l knew what to look for. it took me like an hour on my first try.

 

Ok then, I'll shut the hell up !!

 

LOL. nah its cool brother.
