About 2 ounces if my estimates on what "this much" (holds up fingers spaced about 1/8th inch apart) means are correct.
So how should I go about flushing the system? Yes, its been run already with it in there. Yes it looks like chocolate milk in there.
Can I just drain and refill the reservoir a few times until it looks good and roll with that? Do I need a cleaner to run through it? Don't tell me I've gotta blow it all apart and clean the pieces. I'll sell the car...
I'd flush it the same way I'd flush a transmission.
- Suck as much of the old crap out of the resevoir as possible (do NOT spin the pump!
- Pop the return line from the pump (low-pressure line) and attach to extra line so it can drain into a bucket
- Attach a new section of hose to the pump
- Fill resevoir with fluid so that some of it comes up the hose we just attached
- Put a bolt or something in the hose so it won't leak, and make sure it stays above the pump so we don't bubble air into the resevoir
- Top off resevoir with new fluid
- Spin the hydraulic pump by hand until you see new fluid coming out the drain line into the bucket, make sure you keep plenty of fluid in the resevoir so you don't suck air into the lines
- When you get new fluid flowing through without bubble or discoloration, suck the fluid out of the reservoir, or drain through our hose w/ bolt (pull bolt, let drain)
- Hook up the return line to the pump
- Fill resevoir with fluid, have a nice day
Not sure if there is more to the hydraulic fan then that, but that's what I would do in your scenario. If there are solenoids and what-not involved, you might need to figure out how to activate them manually so that you can flush them too. No clue how much fluid the system holds. If I had to guess 2-3 quarts tops.
