After replacing the head and thermostat, the car is running hotter than it did. Right now it's usually a needle above 1/2. I've blead the coolant two times, so I'm faily confident that that's not the problem. It never goes above a needle below 3/4s. Does anyone else have any suggestions?

I've ruled out the gauge; the upper radiator hose is very hot.
I also have a few questions about the fan clutch. When the engine is hot, it should be hard to move, right?
The temperature seems to alternate daily from running closer to the 1/2 mark to running closer to 1/2 between 1/2 and 3/4s.
Any ideas would be helpful before I start dumping lots of money into new coolant things.The BMW 318 is back. With a vengeance.

After driving around for a few minutes and the temp gague is up, do BOTH radiator hoses get hot? What method are you using to bleed the system? Try giving the dash a good whack above the area where the temp gauge is, it's common for the gauge to get a loose connection. And check that you got the connections right for the temp sender and the temp sensor, one is for the gauge and one is for the motoronic.Adam Fogg- '88 M3

I bleed the system by filling the expansion chamber to cold. Turning the car to ON, but not starting it. Filling the expansion chamber until it's about 2 inches above cold. Starting it, and filling the chamber until nothing but coolant comes out of the bleed screw.
I actually had a question. I'm thinking I got the t-stat disoriented. Is the arrow on the new one supposed to be pointing up or towards the top of the engine (so 30 degrees counterclock wise from up). I installed mine with the arrow pointing to the top of the engine. I will try moving it today and seeing what happens.The BMW 318 is back. With a vengeance.
