I'm having a problem with my 2000 pontiac firebird overheating. It is boiling out of the cap where I add the antifreeze. I have added a new thermostat but it continues to do the same thing. Any suggestions?

My escort overheated so added water then i tried to start the car but it wont start, its cranks but it wont start


need add add antifreeze half antifreeze and water to raise coolant boiling point. replace thermostat and radiator pressure cap.wait until engine cool then try starting it up.depends on how long you drove car when engine over heated.if you turn off engine soon as it over heated no harm done.if you kept on driving and engine die of lack of cooling, and car wont crank you could have blown head gasket warped or cracked cylinder head.

Car is losing water and overheating,Where is it going? Is my water pump bad? I have to regularly add water to plastic radiator container.


if you do not see any water leaking ( dripping ) from under the car then I would say that you should start by adding antifreeze to the car and not just water -- if you are just adding water to the 'plastic container ' there is a chance that the car is just boiling off the water that is added, ( since water boils at a lower temperature then antifreeze ). if after the filling the radiator with the proper mix of antifreeze AND water you are still having a over heat issue -- then there is a chance that the thermostat or the water pump is bad and need to be replaced. could also be a cooling fan issue ( make sure the fan is turning ) --- also make sure the radiator is cooling properly. if you think that there is still a leak in the system you can have a repair shop pressure test the cooling system and they will be able to find the leak.
but again --- add antifreeze to the system and see if this helps first. you can buy antifreeze at your local auto parts store,, and since only water has been added - I would drain SOME of the fluid out of the radiator first and top off with 100% antifreeze so you have a good mixture.
I hope this helps ,, if you have further questions about this problem - please write me back here and ask and I will do my best to help.

My antifreeze is leaking out of my radiator .....HELP : (


adding antifreeze on its own can be bad for your motor.. it needs to be added with water.. does it leak from your radiator cap/ overflow hose or from the radiator core.. ckeck you thermostat as well. it stays closed when the water is cold and opens when it gets hot.. it sounds like it could be stuck shut..

99 Firebird still overheating after repairs and antifreeze


overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.

2000 firebird overheating coolant orange color. Was warming up in Driveway.


The coolant was boiling, am I correct in reading that? A muddy, dull orange color is bad. From what you've told me, it sounds like the coolant was never changed. What happened, then, is the coolant that was in there lost its anti-corrosion properties and started rusting out the coolant paths and radiator. The boiling over can be caused by one thing - the thermostat. What most likely happened is either the thermostat froze up or it is clogged with particles of rust and metal. My recommendation to you is to take your car to a radiator shop and have them look at it. If the damage is as bad as I think it is, don't be surprised if they tell you you will need a new radiator, thermostat, hoses and maybe a water pump.

Overheating


Having the radiator rodded is a good move. Retest. If it has an electric radiator fan check temp sensors. If the fan has a clutch it may need to be replaced if its slipping with the engine hot. Check bellts. Its likely a fan air flow issue if the engine overheats when the care is not moving or is moving slowly. If the engine overheats only with AC on that narrows it down. Write back if that's the case. Lots of things can cause this. Antifreeze and a good radiator cap discourages boiling. Pressure in the radiator raises the boiling point but it can't build up pressure if the cap is bad. Antifreeze also raises the boiling point. If actual boiling happens in the engine then steam builds up in critical places and drives the collant out of the block making the engine even hotter than it already is. Replace the cap. Check the antifreeze.
