Power steering and or water pump?

I need some help troubleshooting guys. I was driving through the Poudre Canyon from Fort Collins, CO to Steamboat Springs, CO when I heard a loud whine and smelled burnt rubber. I immediately thought of my serpentine belt, but did not want to stop because there are no businesses or cell phone service for 30-40 miles. What good could stopping with no belt replacement do me? I'm still not sure if that was the right decision or not; but I drove gingerly the rest of the way to Steamboat with the loud whining of what sounded like a loose belt.

When I arrived in Steamboat, I noticed that when I slowed down, my power steering would go completely out. On Saturday every shop was closed and I opted to go to Napa and Carquest to get a new belt, idler pulley, power steering fluid and power steering pump. I topped off my PS fluid which was low and decided to continue to Utah because I needed to get to work and couldn't wait until Monday when the town started to wake up again.

Here are all my symptoms: When I slow down, my PS goes out. When I speed up, it returns. When driving slowly through town the temp gauge reads hot, but when I speed up the temp gauge cools to normal operating range. All the pulleys appear to be turning. There is a leak somewhere because my PS reservoir was half empty by the time I got to work.

Through the search, I found that most 5.7 owners have had issues with the PS pump. What is the issue with the overheating then cooling? Is it a water pump? What items usually wear at 110k? Since I am planning on doing the PS pump, I might as well swap out the idler pulley and serpentine belt also. Can I do this work on the road with a 130pc mechanics tool set and a couple of crescent wrenches? Any advice would be much appreciated. Thanks!

Re: Power steering and or water pump?

We're you able to swap the belt first to see if that made any difference?

Also, with the 5.7L the power steering requires the use of hydraulic system/power steering fluid meeting Chrysler spec MS-10838.

I would start with the belt and check for any changes in operation before jumping into the rest of the system.

Keep us posted.

Re: Power steering and or water pump?

Ive gone through two PS pumps. One was even brand new and immediatly started to crap out. Mopars warranty sucks on those things. If youre at 110k and havent done it yet, water pump change too.

Also, check your a/c compressor. Mine took a dump recently as well with 107XXX... it was a VERY expensive fix ($700) when the pulley broke off on me. Im hoping my water pump holds up for a little longer as ive been bled dry from repairs. Boresight shows no problems but you never know...

Slightly off topic. Why is it when my GC breaks its big time breakage and insanely expensive? Worse, when the really expensive sh*t breaks it never has any signs or early warning.

Re: Power steering and or water pump?

Something is seizing up at low rpm's. The reason you lose power steering and the temps spike is because at low rpms the crank pully is spinning within the belt so the belt doesn't turn the water pump or the power steering pump.
Did you remove the belt and try spinning all the pulleys by hand? I'd imagine your going to find one that's really hard to turn....

Re: Power steering and or water pump?

The PS pump is shot for sure, losing fluid and with that mileage. Mine went bad at 85k. Burnt rubber smell is the serp belt. The PS pulley or water pump, is probably now sticking, and the belt is dragging across it. Replace the PS pump and belt and at 110k, yep, makes sense to do the water pump too.
