Olds cutlass supreme overheating.?
I recently had the head gasket replaced in my 1996 olds cutlass 3.1L coupe.
Since then it will occasionally redline after just simple driving and I am finding that if I open the air blead valve that is above the waterpump this will cool the engine below redline and then after a bit it will go back to more normal tempatures.
I have been suggested that there is an airlock in my system and that is causing the overheating.
it has also been suggested that the thermostat is sticking causing it.
And finally it was suggested that the headgasket didn't seal and that is injecting air into the system... which would be another very expensive repair job...
which of these is most likely and what routes should I go about fixing the problem without just taking it to a shop and hoping for the best?

Replacing a head gasket is always a prime opening for ccontinuing car problems. It's been said that the pressure is never the same, which I believe is the 'airlock' problem. It could be the thermostat or the water pump itself. The best thing to do is get it back to the mechanic, but make sure (and don't take offense at this) you take a guy with you who knows something about cars. The mechanic will be less likely to give you a bunch of crap that you don't understand.

If you just had it int he shop take it back to them, If it is head gasket related they should repair it for free. I don't usually recommend throwing parts at problems, but thermostats are cheap and easy that would knock one of the items off your list.
If it has aluminum heads they could have slightly warped on the first head gasket blow out. then they would need to be milled.

i would go more towards the gasket not being installed correctly . you can check to see if the thermostat is sticking by turning your vent on in your car if its blowing hot no matter how cold you have it set to its your thermostat. if your thermostat sticks alot of times it will cause your coolant to fill and overrun out of the reservoir.

The action you have already taken indication that there was an air lock. I would at the valve you opened and see if this has an auto control that is failing.

The thermostat in my saturn doesn't work anymore, so maybe that is it. Check and see if your fan is running when the car is.

you should have 2 air bleeders open both uptill you get steady stream if it still red lines its possible head gasket was put in wrong way printed side goes down.
