My car is overheating and leaking coolant, what's wrong with it?
If your radiator isn't clogged up , check to see if your thermostat is hanging up, may not be opening when it should causing your engine to run hot and boil over onto the ground. You could have a blown head gasket ,check your oil and see if you have coolant inside of the oil,it will look milky in colour, you might also unscrew the oil led and look on the bottom side of it to see if there's coolant under it.
Hole in the radiator
It could be a clogged radiator, sticky thermostat, bad radiator cap or a bad fan clutch.
Check to make sure the front of the radiator isn't all clogged up with bugs and debris. Changing the thermostat and radiator cap are cheap so start with these two. You can spin the fan when its warm and if the blade spins more than half a turn its a bad clutch. Rotting out the radiator is cheap too.
where is it leaking from. when your car is cold, open the radiator cap and start the car. let the car warm up. when the car is warm, look at the water in the radiator and see if it is moving. if it is not, your new water pump is not working. is the belt hooked up to it?. if it is working than something else is plugging your water from circulating your engine.
radiator...thermostat(replace both)
Step one, wash engine compartment. Step two, watch for signs of external leaking. Step three, read the GM litigation web-site about Dex-Cool lawsuits. Step four, Go to GM dealer armed with information about this. Step five, in the future, use only Mercedes Benz coolant in this car to prevent cooling system damage for 150,000 miles.
The leaking is likely causing the overheating. Wait till the engine and radiator cool down (the coolant is under pressure and you can get burned or scalded if you try to remove the radiator cap before cool down.
After at least 10 minutes cover the rad cap with a large cloth or rag and slowly turn to loosen, still be very careful, if you hear, see or feel steam; move away and let cool further. After removing cap look inside the reservoir or radiator. You should be able to see if the coolant is low. If in the reservoir there should be a cold and hot line. Top coolant to the line or fill radiator to top. You should use a coolant/anti-freeze but plain old water will do temporary in a pinch.
That will get you going. NOW, you have to find the leak. If the coolant is not low than while the engine is off check to see your belts are tight. A loose belt will cause the water pump to turn slow and also the fan will slow down; both causing heating problems. If that is OK then with engine OFF shine a flashlight from inside thru the radiator, see how much light you can see. If you see very little light as you move the flashlight around then your radiator is plugged or blocked and must be cleaned. This can usually be cleaned with air pressure at a gas station or garage.
Now the leaks. If the leak is at a connection you may be able to tighten the clamp. if the hose is leaking it should be replaced. If it is leaking from the head or block, you may need to move up to a 200 cavalier. Good Luck

You're putting in a 50/50 mix right?
change ur car .....ur car is getting old n dead change before it dies n tell u bye bye
If you are losing coolant anywhere other than the overflow tube, you need to find out why. If you are losing it from the overflow, you need it investigated anyway.
A cooling system place can put a pressure test on the system, and advise.
The overheating can be a symptom, or a cause. You need to find out before the engine is destroyed.
You need a new radiator
where is the water leaking from? If from the radiator, replace it. If you can't find the leak, check your oil and make sure it isn't leaking into it. If it is overheating, you may have blown a gasket.
