How can you tell if your gasket is blewn?

Head gasket I presume. If the car overheats quickly exhaust is getting into the radiator. With it cold, take the cap off and start the car. Water will shoot out of the radiator a foot or two. Check the oil. If water is getting into the oil it will look like chocolate milk. If water is going in the exhaust, you will have large clouds of white steam coming out. Usually it is one of these, in extreme cases you may get two or all of them.


How do you refill water in car battery?

Car should be OFF. If it CAN be refilled you would remove the caps located on top of the battery. Carefully add distilled water until water level is full but not overflowing. Replace caps. Wipe off any spilled water. Do NOT get any water from battery on your clothes, skin or eyes. Do NOT smoke while refilling your battery - it could explode!
