Hmm so it's a 1/4 way up on the gauge? Yeah that seems low to me too. I don't have the car anymore so I can't even go out and check, but I know that mine never made it up over 1/2, except when it overheated... Anyways, it always drove at just at or slightly above the mark at 1/3 rd of the way up the gauge (assuming your gauges are the same as mine, but I think they are). There is an old school way to check if the thermostat is working, stick it in a pot of water on the stove and crank the heat, you should see it open. And use a meat thermometer to check temp.
