1999 Pontiac Grand Am Overheating

I just purchased a 1999 Pontiac Grand Am with a 3.4 liter motor.

The coolant system seems to run dry, I have bled the air several times and changed the thermostat. It will run fine for a little while then the heater stops blowing hot air and the radiator air starts blowing cold, the temp runs up to 250 + I've heard that the head gaskets can blow out on these motors, is this one of the things it does when the head gaskets are bad ? 2001 pontiac gr am gt ram air keeps overheating an coolant going dry i noticed coolant flowing out of overflow when overheating i changed thermostat an tryed bleeding air out still having same problem bout to change water pump maybe that will work .....................ya right these cars **** i need to fix it so i can sell it

It is probably the problem. To make shure that need to change the gaskets, one of the symptoms use to be thet the temp rises when you are running at speed 50+ average, where is supposed that the car gets a lot of air due by the speed and nobody thinks that will be overheated.

2002 Grand Prix, very hard to get started. When it does start air coming back through the raidiotor (apparently) cause the fluid in the over-flow tank to bubble dramatically. This all started yesterday,...

it looks like coolant has been lost and possible the system needs to be bled of air. the bubbling is air returning to the header tank. ensure the system is topped up to the correct level before starting the engine. Ensure that coolant has not got into the ignition system which may be reason why it is hard to start. if so use and water replelent spray to get rid of it and better electrical connnection. Once started check the coolent level and see if it is going down if so let the engine run for a while and then switch off. if needed top up the coolant level futher but only when the engine has cooled. Once this is resovled take the car for a good drive to help heat from the engine to dry out any water that might still be in there.

1: Drain coolant system
2: Purchase coolant flush, making sure you have the proper amount for your size of coolant system
3: Pour coolant flush into your radiator, filling the rest with water
4: On the coolant flush bottle it will tell you how long to run your vehicle
5: Once done running, let cool enough to open radiator cap, and drain system COMPLETELY by first draining out of pep **** on radiator, then taking one side of the hoses off the radiator and draining those
6: Put hoses back on and fill system with coolant. When the fluid gets to the top of the fill port on radiator, start vehicle and let run, allowing air to escape the system, and fill as necessary
