Public Service Announcement: Change Your Soft-top Fluid
So had a blissful weekend of auto repair as all my immediate family members went on their own vacations with friends and I got to stay home by myself.
In addition to fuel filter and CPS (which solved my occasional hard start and stalling issue) - I flushed my soft-top fluid. When I first bought the car, I did an exchange of some of the liquid with a turkey baster and refill, but that was 3 years ago. So this time I took off the return line and ran it into an empty OJ container, cycled the roll bar and soft-top a handful of times until it was fresh fluid flushing out.
Prior to the fluid refresh, my top opening process would pause after the rear of the soft-top was vertical and before the hatch opened. I'd have to give just a quick flick of the switch (not even let go completely, just a half-move forward and then back) and the process would complete. With the new juice, the process starts and finishes as it should.
This is what came out of the pump, and how it looked after. I'm guessing if you haven't thought about this for a while, you probably should. Easy enough to do annually.
