  • Temperature

    What is the expected temperature of the cylinder heads on '95 175's?
    I'm reading ~100* on the stb head and ~120* on the port head.
    These measurements were taken w/ an infrared thermometer while running on the muffs.

    If I remember correctly... those thermostats open at around 143 or so. If I am correct, your readings would indicate the thermostats are faulty or non existent.

    I do not know what the actual head temperature would be... BUT... I think the thermostats require checking into.

      Is there a trick to getting the covers off the thermostats?
      Is it possible the PO or his mechanic used some kind of sealer? I can't get them to budge!

        I've encountered a few that with all the bolts removed, I had to hit the housing sideways with a hammer to knock it loose.

              That's a first!... Mark that tool up in the special tool category.
