One basic thing about cars that some drivers fail to do is on how to handle cars that have suddenly overheated. Normally, cars would overheat due to:

1. Lack of Water
2. Damaged Water Hoses
3. Worn Out Belts (Alternator)
4. Lack of Ventilation
5. Engine Decompression
6. Busted Auxiliary Fans

Normally, a driver would stop the car for fear of breaking down somewhere unknown. But did you know that as much as possible, you should not turn off the engine (as long as it can) manually? If the engine would die normally, then that would be okay. But if you want to put water which is the normal impulse that people would think of, try not to fill up your radiator if you have just shut it down to avoid overheating.

Assuming you have replaced the hose or anything that needs to be fixed that are causes for overheating, try this out.

Cars normally come with a reserve water tank to which reserve water can be placed. If you happen to shut down your engine, it would be best to initially put water there. Once you do, try starting it. If it does, try out these things before turning that radiator cap:

1. Wet a piece of cloth with water and get lots of water.
2. Before you turn the radiator cap, pour water extensively on top of the cap and the radiator. This is to try and bring down the temperature as much as possible.
3. Get the wet cloth and try to place it on the cap first. Wait a couple of seconds and then try to put your weight on it, and slowly loosen the radiator cap. You are bound to feel the pressure from wanting to get out. Do not allow it to do so as extremely hot water is bound to spill all over you.
4. Once you have released the mounting pressure, open the cap and then put water while the engine is running.

Do not turn the engine off (unless you can wait for it to cool down) and place water. The sudden change in water temperature is bad for your engine and may force you to overhaul it if you are not careful.
