Re: heating problem. help please
It would seem that your overheated engine has warped the cylinder head and compression/pressure from the combustion chamber is adding to the pressure of the water/cooling system hence the spitting out. To verify, pls check your oil dipstick and see if the oil has turned to brownish milky color. If yes, then it calls for an engine overhaul, if not possibly air pockets inside engine water jackets.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

if you lost all the coolant most likely the engine overheat. temperature sensor is not accurate if no coolant to touch the sensor.after you fill again,the coolant enter inside the cylinder and kill the sparks.
Remove the spark plugs and inspect for coolant. crank the engine without spark plugs and see if coolant will blow out.turn the engine to cylinder #1 top and pressurize with air. look at radiator if the coolant bubble.
You may have to replace your thermostat. If the thermostat is not working properly, you will have over heat. You make also have a bad thermostat gasket and that's where the water leak from. It might be leaking a little at a time and the engine is hot so its dry before you can see it.
I doubt it. The sensor is for the computer and the temp gauge on the dash. If the heater hoses are getting hot, and the radiator is full of coolant, you may have a blend door problem. The blend doors direct air thru the heater core and the vents.
Raise the front of the car up in the air, fill the recovery tank full of fresh coolant to the top, run the engine until it gets nearly to the overheat Ara of the gauge then shut it off and run cold water over the radiator the coolant will be pulled from the the recovery tank and the air purged out of the system, do not let the tank run dry.
Add a mixture of one-half water and one-half antifreeze to the radiator. Fill it right up to the top.
Fill the overflow/coolant reservoir with the same 50/50 mixture.
Leave the radiator cap off, turn the engine on and let it run until the radiator "burps": You will see the coolant level drop and may see or hear a large air bubble come to the top as the system burps.
Keep an eye on the temperature gauge throughout this process.
Refill the radiator to the top and coolant reservoir as needed.
Put the radiator cap back on.
You might have some air inside coolant system, try follow the steps that i just created. if its not work out please relay me back thanks
This could be a lot of things, but let's start with the basics. WHen the car begins to warm up, does the heat gauge ever go to almost the top of the heat range and then fall quickly - before you engage the heater? If so, replace the thermostat. Failing that, you should check the underside of the car and see if there is any evidence of a leak near the water pump. If there is or if there is a bit of water showing at the weep hole in the water pump, it is bad and needs to be replaced. Failing that, it could be a low coolant level or a plugged up radiator. As an aside, if you are looking at problems such as this now, it may be time to replace the belts and hoses while you poking around if they have not been replaced in the past 3 - 4 years. Are you sure the coolant is a 50-50 mix of water and antifreeze? If you've been adding water regularly, you may have a diluted solution that is boiling and providing the proper cooling.
Hi! Theres a coolant reservoit that connects thru the radiator. The coolant level should not be full, it must be just on the HI / MAX indicator. You fill it too much it will spill and leave you with no coolant to circulate. That may be the cause of overheating. HOpe this helps and have a good one!
you could have an air pocket in the cooling system that has to be burped. With a cold engine, park uphill and leave the radiator cap loose. Fill radiator and coolant reservoir. Start engine with cap loose and run at 1500 rpm until temp gauge reads normal. Feel if top radiator return hose from engine to radiator is hot. If yes, coolant is flowing and thermostat is open. If cold, thermostat is not staying closed until engine is hot.
It sounds to me like you're low on coolant. When you checked the coolant level, did you actually open the radiator cap and make sure the radiator is full? The plastic tank you generally add coolant too is actually an 'overflow' or 'reserve' tank. There is a hose that runs from that tank to the top of the radiator so if the radiator gets low on coolant, more coolant -should- run in from the overflow tank. However in practice this does not always work. I have a Jeep that leaks
coolant and experiences this exact same problem. Coolant will not run from the reserve tank into the radiator because the hose is plugged up, and whenever the radiator gets low on coolant the temp gauge will go real high and
then drop, and the heater doesn't work well. This is because the
cooling system of your car is supposed to be a closed system, full of
coolant and no air. When coolant leaks out, the space it used to occupy
is now occupied by air, which does not transfer heat well. When 'air'
is passing through your cooling system, no heat can be transferred from
your engine to the heater and radiator, resulting in a hot engine and
no heat at the heater. Then when a pocket of water passes through the
system, the temperature gauge quickly falls as the water absorbs the
heat from the engine. The hot water that cools the engine is where the
heater gets it's heat from as well, so when water passes through the
heater core, the heater works, but when it's filled with air, it
