Question Steering reservoir... which way does it flow?

So, I'm planning to replace my power steering pump on our 2009 Enclave CXL AWD. One step will be to flush the current fluid out with new fluid.


Which spigot on the reservoir is the inlet? Which is the outlet? I assume that both are lower pressure. Are both lines going to be 3/8" I/D?



Also, I'm planning on installing a filter in the line. Should I put it to the rear of the reservoir or the front?


Thanks!

Well... did some digging and it appears that the fluid comes up from the cooler into the front of the reservoir and exits at the rear, where it goes to the steering pump.


If you are going to flush, the front of the reservoir is probably the best place to open up the system. This is probably the best place to put the filter as well.
