Qs on brake and clutch fluid flush, thank you in advance.

Just scaling the photo they seem about 30mm long overall so I think it will fit into place, but you'll just have the same problem as you won't have room for a 3/8" square thing to rotate it. If the outer body was hex shaped or had some flats, rather than round, you could put a wrench on that to drive it (that's how EDoug's and Cassidy's solutions work -- enough of the 12mm hex of the tool sticks out from the plug to use a wrench to drive it).

 

Steve has anyone ever converted to dot 5. I have done this on old vettes and silicone fluid is non caustic and is a lubricant

It also repels water not mix. Took a small container and put dot 3 and almost as much water and shook it up. It mixed perfectly. It just looked like twice the amount of brake fluid.

Think about that in your brake system.

 

I can't recall it being discussed before, or much, here, and I have no experience with DOT 5. However, I would only make the switch if a system was completely cleaned and all seals replaced -- i.e., after a complete system restoration, starting with DOT 5 would be reasonable IMO, but just draining a DOT 3/4 system and refilling with DOT 5 wouldn't be great. Also, there's quite a bit of internet discussion that DOT 5 has some foaming issues in ABS systems (so no issue for older F or older vettes, but I've noticed that my wife's ABS-equipped 2020 MB still specs using DOT 4 or DOT 4 plus).

 

Sure, you cant run it in ABS for sure but given the parameters you just discussed I would do the TR. Its great stuff and has really nice chemical qualities.

I have changed over vettes by just doing a flush with Dot 5 and had years of great service. Once its in you dont have to ever touch the system again.

Correct

Both filler plugs should also have fresh sealing washers.

No -- here are my notes on the various Copper washer sizes needed (and they need to be new or freshly annealed -- i.e., dead soft -- do not reuse an old one as-is):

Gearbox fill plug, Transfer Case fill plug, Transfer Case drain plug = 10263460 = 22mm ID x 28mm OD x 1.5mm thick (but 22 x 27 x 1.5 also works)

Large Gearbox Drain plugs (2) = 10265160 = 35~35.5 mm ID x 41 mm OD x 1.5mm thick

 

As stated before, re use copper sealing washers. Heat up cherry red with propane torch hanging from hook, quench in water = annealed.

 

I chose to sacrifice the handle end of the wrench to allow the hex wrench to fight on another day when needed. EDoug Image Unavailable, Please Login

 

Looks like the short leg of 12180 is a little longer than the short leg of the Craftsman tool that I modified so the short piece you'd cut off may be a little longer (you'll want to maintain the 32mm dimension for the short leg as in my sketch of post #17).
