93 Olds Cutlass fluctuating temp gage goes above 200 degrees Just changed Thermostat air bubbles maybe bled already from top of thermostat housing Thanks?

1 Start off with the engine cool, not run for an hour or so. 2 Remove the radiator cap.3 Fill the radiator and/or recovery bottle. the bottle will have a fill line, and fill the radiator until coolant reaches the bottom of the hole for the cap.4 start the engine and let it idle.5 Watch the bottle and fill cap hole for bubbles.6 If it bubbles, let the motor run. If the coolant level drops, slowly add more.7 Watch until the bubbles stop, then shut the motor off, make sure the level is right, and re-cap.

this should burp the system of any trapped air. good luck

PS sometimes this can get messy, espesially if you spill coolant, because the fan can make a nice coolant fog. not usually a problem though.
