This picture needs to be posted on the boobs thread!

Reminds me of a long ago girlfriend in the shower,  are we still talking about Z's?

First some old engine oil in the bowl ,(sits round the edge in pic) then some coolant on it, and finally some atf drops on it.. leave it a day or two and make the pic.

 

Well glad we had some fun. Thanks for the contributions.

It was just antifreeze and ATF. I hoped the relative rarity of automatics in Z’s might make this a bit more of a puzzle. It was the first auto equipped Z I’ve actually done more work on then just yank the auto trans and recycle it. 

Spent a fair amount of time swapping rad’s in this late 71. This involved the joy of removing and replacing the auto cooler lines so the inevitable dribbling of ATF into my coolant recovery tray resulted. The pattern was interesting and a bit artsy so I had to take a couple of pics. Learned alot about the thread specs on the stock hard lines and the rad fittings. AN dash 6 thread on the rad was interesting realization. The hard lines and soft lines are a very curious mix of metric fittings. The hard lines are 5/16 or 8mm.

Glad no one went to the blood and coolant guess.....  yuch.....
