clutch fluid

[Paddy49]

Hi all, help please, my 1965 3.8 s needs a clutch cylinder change, which fluid to use? I cannot locate SAE 70 R3 heavy duty brake fluid, would appreciate any advice, Thanks.

I think the fluid should be glycol based unless you have changed seals etc to be suitable for silicon based fluid. The latest versions of the glycol system fluids are DOT 4 or 5.1. See the attached : http://www.epicbleedsolutions.com/resou ... ake-fluid/
Halfords sell the latest which is compatible with earlier materials : http://www.halfords.com/motoring/engine ... -5-1-500ml
Hope this helps.
