Backround:
Ive own my 05 Sierra 2500HD since new and have done many modifications over the years. Non of which have negatively impacted the drivability or reliability of the rig. I only use it for hauling steel and occasionally for travel. The rig currently has 95K on the clock.
The power steering hoses have been "wheeping" for some time and the Hydroboost developed a drip between the brake master and said booster. I live in SW Arizona so triple digit temps are a regular theme. I was beside myself to discover the absence of a PSC on a rig designed to tow. My wife's 1/2 ton Z-71has a tranny and PSC from birth.....Go figure.
First order of business was to flush out the old fluid and any potential contaminates.
I used some inexpensive PS fluid for the flush and will use the Valvoline after the components are replaced. The only component in the system that will remain is the pump, that being said I wanted to ensure it was cleaned out and free of older burnt fluid.
The set up was simple, I had the rigs front tires just off the ground, a line coming from the hydroboost return to a container. With the rig running, I turned the wheels right to left while pumping the brakes making sure to continually keep the reservoir full. The fluid coming out was nasty and dark. I have flushed this system out twice in the past so I was a bit surprised in the condition of the fluid.
After the entire gallon of the inexpensive PS fluid I had good clean fluid.
Next up, removing the front grill to clean out the cooling stacks.
