200 SERIES AHC FLUID FLUSH-SAME AS THE 100 SERIES?

[Hokie99]

Years ago folks on the 100 series forum came up with a fool proof and consistent way of doing an AHC flush. I have used this technique on my kids 100 series and it took an hour max, even on my first go round.

I understand that the main reservoir is in a different place, but would the remainder stay the same?

B - Bleed: Flush out the old AHC fluid

1. Procure three 1L bottles of OEM AHC fluid (08886-81221)
2. Put AHC in Low, turn engine off
3. Suck all old fluid out of AHC tank (~1L if level was between Max/Min at N height)
4. Pour in new fluid to top of tank (~2.5L)
5. Bleed accumulator until fluid stops (long cylinder on left side frame rail) (~300mL, 10mm wrench)
   • Bleeder torque spec: 62 in-lbf (5.5 ft-lbf, 7.5 N-m)
6. Bleed one front and one rear damper (globe unit) until both front and rear are on the bump stops and fluid stops flowing (~300-400mL each)
   • Bleeder torque spec: 73 in-lbf (6.0 ft-lbf, 8.1 N-m)
   • Careful, as the car will lower significantly during this process. Don't put yourself under the vehicle!
7. Start car, put AHC in Neutral until pump stops, turn off again
8. Bleed the remaining front and rear dampers on the other side of the car for just a second until fresh fluid and no air comes out (~50mL each)
9. Start car, cycle to AHC to L then back to N
10. Top off AHC fluid in the reservoir. Should be between Max/Min at N height.
11. Recheck graduations in the tank as described in step A2. May see some improvement, may not.

Anyone?

It’s similar, but plenty of threads for 200 series process. Here’s the one I bookmarked. There’s also the AHC Basics thread. I think the 200 system requires more fluid, I wouldn’t start the job without 5 QTs.
