    Re: Removing the Previa HVAC panel

    Sure. As I no longer have my Previa, I no longer need the tool. That said,

    I need to put my hands on it, which means rummaging the unused Previa parts that I still have not gotten rid of over the...

    Thanks for making that check. I'd say it does rule out the relay; the only difference is that POWER MAIN is normally on, and OIL LVL normally off. I'm surprised the coil draws enough current to get...

  18. Re: Has anyone replaced their distributor shaft seal?

    The one on the shaft. I know it's thicker than the other one, but my recollection (assuming I can trust it) is that I used the picks to remove the old one and help set the new one.
  19. Re: Has anyone replaced their distributor shaft seal?

    It has been over a decade since I replaced mine, so my memory may be hazy, but I don't recall needing anything more than my Harbor Freight mini-pick set to remove the old seal and place the new one.
