damaged or faulty radiator If coolant is "pouring" out of the radiator with no damage evident, could be stuck thermostat, especially if it happens soon after starting car. Could also be blown head gasket if pouring out of the fill tube with cap off.
Look at the lower or rear of radiator
It is in the lower radiator hose
Yes it will.
That all depends on what kind of antifreeze was in there before. It comes stock with the green color. but if there is another color in there now either put the same color in or flush the whole system and put the desired type in there. If you mix colors your system will become clogged with antifreeze jello :(
Dex-cool is recommended to be changed every 5 years.
A 1996 Pontiac Sunfire uses Dexcool coolant. This should only be mixed with distilled water, never tap water. Replace the coolant every 2 years or as needed.
The radiator cap is on top of the radiator. It is located near the front of the engine compartment towards the right side of the car.
A Haynes or Chilton manual will have detailed instructions on how to get that radiator out. I highly recommend that you pick one up. I think they're about $17.
It's located on the engine side of the radiator. Lower passenger side. You have to get under the car to access it though. You can't see it from the top.
On top of the reservoir on the passenger side of the motor. It will say Caution do not remove when hot!. There is not one located on top of the radiator itself.
Call in the pros. I'd take it to a radiator shop.
