OK, someone please advise me how in the heck you add oil to the top reservoir? I have the back seat back out, subwoofer out and protective panel out, along with all the trim. It seems you need to have the hands of a three year old to get to the fill nut on the reservoir. I am at the point I am about to drill a 2" hole in the deck above the tank to get to it. Any ideas? Thanks in advance.

 

need to post year and model. I searched and cant find any clips on utube or info on how to do this. nothing in owners manual? might be worth it to take to chevy shop and pay them to do it while you watch so you will know how in future

 

Well I posted in the 2010+ area so that should narrow it to the last generation. In addition, there is no difference in the convertible mechanism of these these years regardless of the model. Believe me, I went through you tube and google videos as well as the owner's manual which were no help. The only help of the videos was how to take out the rear seat back and subwoofer to get to the top pump. The surround trim covers the area, so it will make doing this job again muck easier.
I finally decided to take a hole saw and cut a 2" hole above the fill cap and was able to access the the cap. Even then as you back out the cap it hits the adjacent metal and you have to pry the pump over to get it out.
I did find out one thing however. The manual will tell you to check and fill the reservoir with the top up which is almost impossible due to space limitations. I found if you fill to the top with the top down, when you put the top up the oil level will be right between the add and fill lines.
Another goof of engineering in this generation design. They couldn't put the pump under the spare tire like most convertibles???
