I have a 97 2.2. I want to bleed my coolant system but my valve on top of my bleeder is broken off. So is there another way to take air out of my coolant?

Best way Ive found to bleed cavaliers & Sunfires, Is this way:

First take off your'e coolant cap, Start up your's car. Allow it to warm up to normal Temp, Then after that apply your'e foot to gas peddle, allow the rpm's to reach 1,000-1,200 rpm's. hold it for 5-10 mins. Then allow you will see the gauge move a little bit that normal. Then allow the car to idle for 5 mins, You should notice the coolant bubbling out the Reservoir a little bit that normal. Then allow the idle to be set 1,000-1,200 rpm for another 10-15 mins. After that top up the Reservoir with coolant, Put the cap back on the Reservoir. Your'e cooling system should be free from air.

Good Luck.

Thanks I'm going to try that.

Jack up the front of the car so that the upper pipes to the radiator are higher than the rest of the system. Air seeks the highest spot, sitting level that spot is the bleeder screw.

I don't have a bleeder screw anymore so I need to find another way to bleed it.

Dave is right but he didn't mention to loosen the radiator hose or cap and release as much air as possible..It should work.
You could try idling the car with rad cap removed while jacked in the front also.
