My daughter and I do a little preventative maintenance on the Miata. There was a little bit of ticking in the tensioner and idler pulleys so we decided to go ahead and swap them out and install a new serpentine belt. While we were in there we decided to also install a new Moroso aluminum power steering reservoir. At some point we'll install the matching aluminum coolant reservoir but the one we have now is new so can't justify it now.
