Wun Tunn Zoop gets a replacement power steering cooler assembly

I finally got around to replacing the bad cooler assembly

The power steering cooler was bad when I acquired the van and I just jumped around it way back when. I’m talking  about totally rotting to the touch. The brackets were so gone you could bend them by hand. It has been that way and I had actually went and bought a replacement  GM unit but I never put it in. It’s importance is that the diesel is a Hydro Boost braking system that uses the PS system for its’ power.Lots more fluid and stress on it.

Since I had a free morning I decided to give it a go. After a bit of scouting it was not a bad job.  The cooler is bolted to the frame under the radiator support with the lines going up  to the steering box and power steering pump. The first thing to go was the air cleaner box. It sits right in the the way of all the good stuff. With it out of the way it was an easy go to undo the line to the steering box and the return line to the pump.

The Right Tools For The Job

But … It turns  out this hard line is an 18MM. Of all my line wrenches I did not posses an 18MM. So I went to O’Reilly’s and got one. Easy enough. Then the disassembly began.  With that the line came off with a small bit of effort. Then the return line was a quick clamp removal and a pull. I was smart enough to put a drip pan under the area to catch the PS fluid.

This is where I got a small dose of “what did I just do?” After releasing the lines and the excess fluid was drained into the the catch pan I slid it out of the way. So I thought. As I was undoing the bolts holding the damaged cooler assembly from the radiator support I shifted around a bit to get a better angle and that’s when I  dunked the whole back of my head into the fluid! Oh! Yeah! Nice! But since I was already on it I just went ahead and finished the cooler removal. Then I went inside and decontaminated with a hot shower with 3 shampoos.  Then it was back out to the job.

Hookin It All Up

It was a simple job to embed the new cooler and plumb in the lines. All connected and tight. I topped off the PS system with what I had in the shop. I may need more but that can wait till tomorrow.

 

 

 

More POWER STEERING calls on the HHR

I had a couple more “POWER STEERING” calls on the HHR yesterday

So I guess a fix is in store

I got the first call back on May 20 and I got two more while I was out and about  yesterday, June 21. It appears that the problem has become chronic so a fix needs to be done ASAP. The call is a notification of a failure in the EPS [ Electronic Power Steering ] system. When it appears you instantaneously get full manual PS. Depending on when it happens it can be a bit surprising. There have already been a variety of recalls related to this failure on this family of vehicles. The quick and dirty temporary fix is a shut down and restart. That resets the fault. But it can, and will, return. The big fix is to simply replace the EPS motor.

What is EPS?

EPS [ Electronic Power Steering ] is used on a variety of GM vehicles and instead of the conventional fluid pump plumbed to the steering rack you have a high-torque motor plugged into the side of the steering column that actuates on-demand. No fluid involved. Simple and effective. Well … until it fails out!

And a bit of research revealed that the normal mileage window for this failure is 60-70K. Right where I am at! The fix and R&R are actually very straight forward. A couple of 14mm bolts and a connector and that’s it! No adjusting needed. So a quick trip online to Amazon and I got a genuine GM replacement part [$68] ordered and on it’s way. I decided no rebuilt or aftermarket parts for this kind of part.

So I will wait for the new part to arrive and as soon as it gets here I will get it installed. I found the videos and watched them so it should be a simple see and do. They say about 30 minutes to fix. A pretty reasonable and easy fix for a a new car. Well .. 2006 is kinda new. Stay tuned!
