    Different way to do thermostat replacement

    I bought the 160F Sierra Mercruiser Thermostat 18-3555.
    I used the Riva cutting tool from a friend but Kinchyle's way with a soldering iron would work fine too. http://greenhulk.net/forums/showthre...ght=thermostat

    After dropping in the replacement thermostat I coated the o-ring with plumbers grease, ran a bead of ultra-black silicone around the top piece and forced it into place on the housing. Next I used a quick grip clamp and 1x4 scrap piece to hold it tight together. Next I drilled 6 pilot holes for some #4 x 3/8 stainless screws and screwed them in. I think this may hold better than jbweld and gives it tension all around the top. I have not leak tested it yet. I'm hoping it will last okay but if not, I can remove the screws and take it apart again.

    I got mine apart very carfully and was able to snap it back together. I didn't put a new thermo in, I blocked the center off and am using it for an open loop setup and it works great, no leaks

    We used to drill holes in the outer part of the stat so that air could escape.
    I wonder if that lowers the temps any?

    I would like to lower the temps another 10 degrees or so.

    isnt there some kind of jig someone can make up to properly snap the thermo housing apart???
    what about heating the whole housing to make the plastic more pliable???

    Nice work. Is there really no good way of getting it apart so it will just snap back together without using epoxy or screws?

    I did this to 2 skis, u could not tell I was even in there, but tried an older housing and it was too brittle.
