    Question on Thermostat Orientation

    Guest-only advertisement. Register or Log In now!
    When installing the thermostat, does the vent hole go to the top or the bottom? There is also an arrow opposite the vent hole, so if the vent hole is up the arrow is down. I would think the vent hole would go up, but it doesn't seem like they would put an arrow pointing down.

    Thanks

    Thanks!

    I was thinking that should be right, but the arrow confused me. Also, when the vent hole is up and you drain the coolant and pull the thermostat housing, there is still a pool of coolant behind the stat to give you a bath when you it. I was second guessing that maybe they wanted the arrow up and the vent down so it would drain better. I'll just quit trying to think like a German because it's not working. I'll install the vent up and forget it! Thanks again.
