Ford power steering pumps make a particular "whirring" noise sometimes. Cold start at -20 below, or the pump is ready for overhaul.

If it is possible have a Ford experienced person listen to it or remove the belt with the engine cold and start it and see if the noise is present.


I could be wrong.. but I think the new Fords have electronic steering.. I don't think they have power steering pumps any more. My 2013 doesn't seem to have one. At least there is no dip stick for one.

Okay....I'm replacing the idler pulley and the tension pulley and assembly.

When I got out the idler and gave it a spin, it spun more freely than the new one....about 2-3 times longer if in spin it. Apparently, when these go bad they spin longer (you want there to be some resistance). So the Idler pulley is not horrible, but I replaced it anyways.

When I got out the tension pulley and assembly I gave the pulley a spin. It spins and spins and spins for a long time. This is a sign that it is bad.

So now I've got the new pulleys in. The new tension assembly has a different type of pin (tensioner pin??). See photo:

Can anyone tell me HOW TO REMOVE THIS PIN AND WHEN? I've got the new pulleys all installed but the pin is still in. Hopefully one of you can tell me how to get it out! :-)

Question: I'm assuming you install the tension pulley assembly and get the serpentine belt back on and in place AND THEN you remove the tension pin, RIGHT?? But how?

Thanks!!

I'm not trying to be a smartass, but you might consider investing in a Shop Manual for that year engine.

Also check Youtube, there are tons and tons of videos to fix just about anything.

Best wishes to you.

I google and youtube like crazy!

I have searched dozens of youtube videos on this subject. Plenty that show how to replace all sorts of tension pulley assemblies but not one that shows how to remove this pin. I have it installed....I just can't get this pin out. It seems like there is lots of tension on the belt even with this pin in, but I can see that it looks like it wants to be removed and that might allow the pulley to tighten an additional 1/4 inch on the belt.

I put a socket wrench (for leverage) onto the pulley to release the tension to get the belt on. I even tried releasing the tension this way and remove the pin....but the pin just doesn't seem like it wants to budge.

Anyone have any thoughts?

Thanks!
Chris

I believe what you are calling a pin is actually the end of the tensioning spring. It's not intended to be removed.

Agree with 2112's post. End of tension spring. Do not remove is my recommendation. Why do you want to remove it. (i'm pretty sure it does not work like a timing belt tensioner where in that case, your remove the pin to allow the plunger to come out.)

Yes never seen a removable pin in many different tensioner pulleys.
Is the belt tight?
Good call. If 150k, it’s about time.

Couldn’t hear the noise in the video. But if it persists, could be fan clutch as well.
Good luck.

If there is a something in the tensioner assy that needs to be removed before flight the instructions that came with the assy would likely say that. They would not want a metal piece to come out and take a trip through the accessory drive systems when the engine is running at 4000rpm.

Update....

Regarding the pin looking item...My mechanic tells me that's just part of the tension assembly and it should not be pulled.

Regarding the noise, it was diagnosed as a leaking exhaust manifold (one bolt had broken off). It makes sense that once things warm up and expand the noise goes away. I've heard exhaust manifold leaks before (when more bolts have broken off) and it was a much louder rumbling sound compared to this. Always learning...

The "good news" is that this RV had the manifold replaced 10k miles ago (~$8k repair bill) and it is still under warranty, so the shop is going to fix it.

Thanks for all the suggestions/etc.

Happy Camping!
Chris
