okay so searching the forums and found out the there may be air in the system but am confused as to how to get it out. I get the car up to operating temp and then hold the upper radiator hose? and then open the bleeder on top of the thermostat housing? is this right?

Several times I have changed my coolant, replaced head gasket once, replaced water pump once, and replaced radiator,and I have never had problem with air in the system. I top off the radiator, start the engine with heat on high, and add coolant to the system as the coolant drops in the reservoir tank.

The only time I had an overheat situation was when the aux. fans or the main fan wasn't turning on due to defective temp. sensors.

check your temperature sensors. Check your water pump, it may be defective and you may have a clogged cooling system.

Pressure test the system...may be a popped head gasket.

190's typically aren't that difficult to 'burp'... It also helps to have the front end of the car up...

This never happened on my Mercedes but when I had that problem on my old van it was a clogged up radiator. I am not sure how to test for that. A radiator shop could probably test it for you I imagine.
