Question -
I am the original owner of a 1967 Pontiac GTO convertible.  I need to add fluid to my power top pump/motor because the level is low and my top moves up and down slowly.  I DO NOT want to mix the wrong fluid.  Therefore, I need to know what fluid was used from the factory.  Through the years, the factory fluid on later models may have changed.   I need to know what was used in 1967.  Can you help?   Thanks, Paul

Hi Paul
     OK as far as the fluid for the top, that type of fluid has been the same for the years 1940 - 1972 and it is just std. hydraclic fluid, (cherry juice) and the new fluid is made even better,  so all I would do is try to suck out as much of the old fluid as you can get out than add the new, and if you can bleed the system if needed. ok

Roger, thanks for the reply.  May I assume you mean standard DOT 3 Brake fluid?  I'm still a little confused.   Paul

Answer
HI Paul
 Wow I forgot that there are the two types so it is the std. heavy duty brake fluid and if it is red in color it is the a.t.f. type.(cherry juice) but only if it is red in color. so use the dot 3  that is fine but try to get all of the old stuff out first ok  .
