Whatever you use, if it comes in a bottle with a small screw cap, DO NOT let that stupid little foil and paper seal in the cap fall into the PS pump!!
I did in my last truck. I fished for 5 minutes trying to find it, then waited for a while hoping it would float back up.
I wasn't where I could do any major work on it, like pulling the pump, and I had somewhere I had to be.
So, I cranked up and took off.
Worked fine. About 3 weeks later, I was turning a corner in town and lost all power steering.
My reflexes were quick enough that I was able to grab the wheel tighter and honk down on it and still make the turn.
A few seconds later, the power came back.
Fine for a few more days. Then, making another turn, it quit, and then came back just as I was cranking down hard. I nearly drove up on the curb.
I flushed the system two or three times, no luck.
In a car, it would be bad enough, with really big tires, it would be undrivable. But, I was running 33s, and I was strong enough to make the turns with no power, but when it came back on during the turn, it was nasty.
Finally I got fed up. Took it to the shop I was using, told them to replace the pump, steering sector, and all hoses.
They wanted to argue, said they could find the trouble cheaper than that.
No way, that truck had to roll, and I needed it reliable.
One of the mechanics asked if he could have the parts. His system needed work on his truck, and he was certain that he could make my stuff work.
Told him, sure. Rolled out that afternoon with all new hydraulics. Never had a minutes trouble again.
3 weeks later, I was at the shop for some minor thing, and the mechanic pointed to his truck. Perfect imprint of a telephone pole back to about the block.
Front bumper almost wrapped far enough around to lock it to the pole.
Said that flushing and reverse flushing did not seem to be enough........
Also said that after he got the frame straightened, all the parts replaced, and the truck repainted, it would not have one single piece of my old steering system on it.......
