Low oil could be a reason for a blown head gasket. No lubrication causes more friction and metal fatigue.
A blown head gasket can cause many problem like coolant leakage and reservoir overflow and can lead to much bigger problems in a big hurry.
If you can't fix the car then you do have one option left, but remember that the car is still broke! Don't idle in traffic or drive it more than 30 miles or attempt this in the Winter when temps are below freezing and make sure you plan ahead and allow your car to have some cool-down time. If you have to use the car then here is what you can do to get by...
I had a blown head gasket on an '83 Ford pickup that did the same thing and it lasted until the body rusted out. What you can do is loosen the radiator cap to the safety notch. (DO NOT DO THIS IF THE CAR IS HOT!!! Scalding water will burn in less than a second!!! sorry.... gotta point that out) This will allow some of the pressure to escape along with some water. Your car will still continue to puke out water like it did before, but if you always make sure it's full before you leave again... you won't have to walk. Carry at least two gallons of water with you wherever you go.
Hats off to your needed repair cause that's a schit load of elbow greese right there. I give it 8½ tubes on my difficulty scale!!!
It might be a bad thermostat, or something worse, such as a blown head gasket/cracked head. Either of those scenarios will cause the cooling system to pressurized beyond it's specified capacity, and the pressure will force the coolant out of the reservoir.
Some symptoms of a blown head gasket are white smoke out the exhaust, using coolant, blue smoke out exhaust, using alot of oil, running crappy and overall sputtering. Otherwise checking cylinder compression would also indicate this.
There's alot of ways you can test your vehicle for head gasket ,but the best way would be a cylinder leakage test,because once you see bubbles going into your coolant reservoir/over flow tank confirms this issue .This is a DIY job
have the head gasket replaced
In most cases is is blown head gasket. The engine suckes air through the hole in the gasket and sends it to cooling system. You never know how long it gonna last. Can also be caused by a defective pressure relief valve in the coolant reservoir cap. If it is the head gasket, you may also find you can smell combustion gases in the coolant. These won't smell the same as the exhaust gas though as the exhaust has been through the catalytic converter. If changing the cap fails to cure the problem, disconnect and isolate the ht leads or coil low tension wires and remove the pressure cap from the coolant tank. Get someone to turn the engine over on the starter motor while you look into the tank. If you see bubbles emerging in the coolant, it's probably the head gasket. And a worse case scenario, a cracked head is possible.
if the coolant in the overflow rises and overspills when you shut the car off or is boiling in the reservoir
head gasket
Usually a blown head gasket.
Head Gasket leak most likely.
If you mean coolant in the engine oil reservoir, then yes, it is slightly possible, but very unlikely, that the engine block water jacket has developed a hole between the water and oil pathways. Other than that, the head gasket is the only place where oil and water can come in contact with each other unless your car is equipped with an engine oil cooler which is internal to the radiator (very unlikely). If you are referring to coolant being in the radiator overflow reservoir, it is supposed to have coolant in it. When the engine is cool, the overflow reservoir should be around half full.
thermostat or blown head gasket....
Coolant overflowing from a 2003 Cavalier overflow tube usually indicates a blown head gasket. Check the cylinders for proper compression to confirm a blown gasket.
A bad gasket can cause the air fuel mixture to enter the coolant stream, and cause bubbles in the overflow bottle. The gasket needs to be replaced.
You will notice the coolant reservoir level low with no signs of leakage, as the condition advances you may notice white, sweet smelling exhaust coming out the tail pipe and worse, engine coolant mixing with the engine oil.
It is probable that you have a blown cylinder head gasket. It's possible you need a new thermostat. Depends on where it is bubbling from. From the top of the engine? Cylinder head gasket. From the overflow on the coolant reservoir, thermostat.
This is a indication of a blown head gasket,unless it has been over filled or overheated.If you are getting combustion in the cooling system you will see air coming up through the coolant in the reservoir,be careful it can blow hot coolant out without any warning.Most shops have a tool that will detect combustion gases in the coolant,it should be a inexpensive test.
a gasket as a rule
