I noticed the top on my 95 convertible has a hard time returning back to top up position. I believe the reservoir pump needs to be filled. Does anyone have advice on how to do this? Does the reservoir plug utilize a hex wrench to open or am I mistaken?

 

It uses an allen key I believe, look through the clear reservoir and see how much oil is left in it. It may have leaked out, if so do not run the pump dry! Fill it up with a 10 weight SAE oil
