In hydraulic systems, fluid is used to transfer force and enable movement. When the top goes up, hydraulic fluid is directed into the cylinder that raises it, increasing the pressure and causing the top to lift. Conversely, when the top goes down, the fluid is released from that cylinder, allowing it to lower as the pressure decreases. This fluid movement is essential for the smooth operation of hydraulic mechanisms.
The fluid used in the hydraulic system for the convertible top of a 1966 Ford Mustang is typically a hydraulic fluid, often referred to as "convertible top fluid" or "hydraulic top fluid." It's important to use a fluid that is compatible with the system, commonly either automatic transmission fluid (ATF) or a specific hydraulic fluid recommended by the manufacturer. Always check the owner's manual or service documentation for the precise specifications.

In the back of the convertible there should be a black rubber plug all you do is get any type of hydraulic fluid( make sure the hydraulic fluid in the back says mixs with any hdraulic fluid) you pour it in the cylinder shape in were you took out rubber plug make sure it over flows and plug it back in and your done your top should now go up way faster, smother,and nice.
To change the hydraulic fluid on an XK8 convertible top, first, ensure the top is fully closed and the vehicle is on a level surface. Locate the hydraulic reservoir, usually found in the trunk area, and remove the cap. Use a syringe or a similar tool to extract the old fluid, then refill with the appropriate hydraulic fluid until it reaches the recommended level. Finally, cycle the convertible top a few times to ensure the new fluid circulates properly and check for any leaks.
