Thank you for the video. But I am looking for a more definite answer Because according to the video you posted. The upper hose is the return. But the parts diagrams I have been
studying for 1st Gen show me that Line 2 in my pic is the return. So I am still confused lol. Here's the diagram. The full part number for the line in the diagram is 4440621110
Just my opinion, this is handier than the coiled hose and bucket in the video. Toyota uses ATF for power steering fluid and it'll ruin paint.
The 3/8" brass nipple fits the return hose. Everything stays inside the engine bay (where drips aren't as consequential.)
The bottle cap has an air hole to allow flow.
Before you change the fluid, get it hot. You want to trap as many particles in suspension as possible.
Three or four Figure 8's in a local parking lot should heat the fluid in no time.
Try to drain while the fluid is still hot to avoid particles falling out of suspension. May need gloves.
My reservoir is black. At this moment I don't want to make a mess by removing the the hoses. If I were to use turkey baster only to remove the fluid in the reservoir and refill it with fresh ATF, will it eventually remove the black residue in the reservoir. It is harder to read the level with it inside. If yes, after several cycles the reservoir is cleaner, how many cycles do I need. I plan to daily drive the car for several weeks before recycling the fluid. Or am I wasting time and mind as well remove the hoses and pull the reservoir and cleaning it with brake cleaner?
A turkey baster is good for two or three ounces at a time. At several weeks per change, it will take 6 to 8 months to cycle a pint of ATF. It's not a waste of time but will take longer than a single change. And new ATF will clean the reservoir. Unfortunately, 25 to 30 thousand miles is enough to blacken it again.
