I believe I have air in my cooling system after replacing my thermostat. I used an original 190 t-stat, and the float is on top. I have run it at idle with the radiator plug out, but I think I still have air trapped in the system because it's heating up more than normal.

What's the best method to bleed all the air out? Do I need to deal with the metal plug on top of the engine? If so, what's the recommended procedure?

Appreciate any input. I'd like to get this taken care of before the weekend.

I just keept checking my wifes discovery after replacing the waterpump. It took about a week to get all the air out by itself.

I found a good article that covers bleeding the cooling system.

I followed their instructions for the most part. The bit about removing the fill tower plug while the engine is warming up is easier said than done. Coolant wants to spray everywhere. So I did the following...

Removed the fill tower plug, connected a washing machine water hose to the tower, put a clamp on it, and ran the other end into a gallon jug. I then started up the Rover and let it pump out about a half a gallon of coolant into the jug (I believe this pushed out most of the air). I then shut it down, let it cool off a bit, and poured most of the coolant back in the fill tower. Then I let it run with the fill tower plug loose so air could escape. I tightened it down when I stopped seeing air bubbles. Later I topped it off via the expansion tank. That seemed to do the trick, and it kept me from creating an enviromental hazard. ;)
