97 Overheating

Replaced waterpump, thermostat twice. Temp goes up and down like bad thermo...can't seem to get the air bled. Anybody want a clean 97 with 108k miles for a thousand? I am tired of fighting it!

How about the temp sensor.
Hows the oil is it brown like coffee if so it the heads that are no longer good you would spend (well, in my case and home town 700.00 dls) to fix them. After that car ran fine.
